Evaluation depth.This is an independent, public-source provider profile and buyer’s guide. We reviewed PreVeil’s public CMMC, pricing, documentation, and customer materials and cross-checked every regulatory claim against primary sources (32 CFR Part 170, the DFARS clauses, NIST, the NIST Cryptographic Module Validation Program, and DoD CIO guidance). This is not a hands-on lab test, and it is not legal, contractual, assessment, or compliance advice, nor a guarantee of any outcome.
Disclosure & independence. The Defense Compliance Report is an independent trade publication on CMMC 2.0 and DIB compliance. We are not affiliated with PreVeil, the Cyber AB, the CMMC Program Management Office, DIBCAC, the Department of Defense, or any U.S. government agency. We were not paid or sponsored by PreVeil to produce this review, and the calls-to-action on this page route to a neutral provider-matching form, not to PreVeil. We may receive compensation for qualified introductions through our independent matching service, as disclosed on our editorial standards page.
This PreVeil CMMC reviewis built for the decision you’re actually making, not the one the sales deck wants you to make. You’ve probably already seen the pitch: 75% cheaper than GCC High, customers with perfect 110 scores, compliance in months. Some of that holds up under scrutiny. One piece of it is where most contractors get burned — and it has nothing to do with the software.
Bottom line up front:PreVeil is a legitimate encrypted email and file-sharing service that defense contractors use to protect Controlled Unclassified Information (CUI) for CMMC Level 2. For a small or mid-sized contractor whose CUI mostly moves through email and files, it’s one of the strongest value plays against the alternatives, and it can take a real bite out of your scope and cost. But PreVeil is not, by itself, a complete CMMC solution— no product is — and “supported by PreVeil” is not the same as “covered for your assessment.”
Your situation
PreVeil fit
Why
3–25 CUI users, mostly email/file exchange
Strong fit — evaluate it
This is exactly the workflow the enclave was built for
You must keep using Microsoft 365 Commercial
Potential fit — if CUI stays out of M365
PreVeil overlays M365 Commercial, but only if CUI is truly confined to the enclave
Heavy CUI exchange with outside suppliers
Strong fit to evaluate
Partners join free — just keep that exchange inside PreVeil, not in Teams or SharePoint
CUI lives in Teams, SharePoint, CAD/ERP/PLM, or on endpoints
Risky unless tightly engineered
The data-flow problem can exceed an email/file overlay
You handle FCI only, not CUI
Probably more than you need
Level 1 (FCI) is far lighter — confirm you even have CUI
You’re a large prime already standardized on GCC High
Compare carefully
Re-tooling around an enclave rarely pays once GCC High is entrenched
You expect “CMMC in a box”
Wrong expectation
CMMC assesses your organization’s implementation, not a product
PreVeil can be a strong CMMC Level 2 option for contractors whose CUI is concentrated in email and file sharing, especially small and mid-sized firms that want to avoid a full GCC High migration. It is a weaker fit when CUI is actively created, discussed, or stored across Teams, SharePoint, CAD, ERP, or unmanaged endpoints, because an email-and-file enclave can’t reach data it never touches. CMMC Level 2 maps to the 110 security requirements in NIST SP 800-171 Revision 2; PreVeil is a tool inside that obligation, not the obligation itself.
The honest decision rule is about data, not vendors. Before you ask “is PreVeil good,” ask “where does my CUI actually live, and can I keep it inside one controlled channel?”
You’re a strong-fit buyer if:
You’re a small or mid-sized contractor and a limited number of people touch CUI.
CUI mostly arrives by email or file transfer, and you can train users to keep it inside the enclave.
You want to keep your existing Microsoft 365 rather than rip and replace.
You have an internal team or outside provider handling endpoints, identity, logging, policies, and your SSP/POA&M.
Look elsewhere — or get matched — if:
CUI gets worked in Teams channels, stored in SharePoint, or edited in CAD/PLM and ERP systems outside any enclave.
Your people will bypass the enclave under deadline pressure (this is the quiet killer).
You expect a tool to produce a certification without the program work around it.
You handle only FCI. Level 1 is 15 basic safeguarding requirements — a paid CUI enclave is almost certainly more than you need.
Decide before you shop.
If you can’t yet say where your CUI lives or whether you can confine it, that diagnosis comes before any tool decision — and it’s the single thing that most often gets skipped.
What is PreVeil, and how does the enclave actually work?
PreVeil is an end-to-end encrypted email and file-sharing service that creates a small, walled-off “enclave” for your CUI, hosted in AWS GovCloud. You confine CUI to PreVeil and keep using your existing Microsoft 365 or email for everything else, licensing only the users who touch CUI. Founded in 2015 and based in Boston, PreVeil is a software vendor — not an assessor, not a certification, and not a one-stop compliance program.
The model is the opposite of the conventional answer. Most contractors are told to migrate their entire environment into Microsoft GCC High, a separate U.S. government cloud. PreVeil instead installs alongside what you already run, routes only CUI through itself, and shrinks the footprint that the hardest controls have to cover. Four design choices make it work:
End-to-end encryption.Messages and files are encrypted on your device and decrypted only on the recipient’s. PreVeil states that no one else — not even PreVeil — can read your data.
It overlays your existing tools.You keep your email address and can send through Outlook, Gmail, or Apple Mail via a plug-in, or use PreVeil’s own apps.
Free external collaboration.Suppliers and partners create free PreVeil accounts to exchange CUI with you — there’s no per-seat cost on their side.
GovCloud hosting. PreVeil states that CUI is stored in AWS GovCloud, which holds a FedRAMP High authorization at the infrastructure layer.
The one distinction most people miss: CMMC certifies organizations, never products. There is no such thing as a “CMMC-certified” software product. PreVeil can be a major part of a compliant environment, but it’s your company’sassessment — covering your whole CUI scope — that earns a CMMC status, not the software.

What did we verify about PreVeil — and what’s only company-stated?
We separated three kinds of claims: primary-source regulatory facts, PreVeil’s company-stated marketing, and the items only you can confirm with the provider’s evidence pack. The most consequential finding: PreVeil’s FIPS claim checks out at the source — at the cryptographic-module level. Its GovCloud hosting is company-stated unless you verify it against AWS/FedRAMP evidence for the specific service, and other claims (“supports 102 of 110 controls,” “85+ perfect scores”) are self-reported and yours to validate.

What you must request before relying on it
Applicable baseline?
CMMC Level 2 requirements are the 110 requirements in NIST SP 800-171 Rev. 2 (32 CFR Part 170). Rev. 2, not Rev. 3, is the controlling Level 2 baseline unless DoD amends the rule.
Markets its CMMC solution around Level 2 / NIST 800-171.
Rev. 2 is the controlling Level 2 baseline.
Your contract clause, required CMMC level, and assessment type.
Does PreVeil certify you?
When a contract requires Level 2 (C3PAO), an authorized C3PAO must perform the certification assessment.
Publishes customer 110-score stories.
PreVeil is a software/CUI platform, not a certification.
DoD CIO memo (Dec. 21, 2023): FedRAMP Moderate equivalency does not confer FedRAMP Moderate Authorization.
States its Gov Community offering is "FedRAMP Moderate Equivalent" and was the "first CSP" to meet the requirement.
The legal distinction confirmed. AWS GovCloud (the host) is FedRAMP High authorized. We did not see PreVeil’s full Body of Evidence.
The 3PAO-assessed Body of Evidence, the Customer Responsibility Matrix, and proof of zero control-related POA&Ms.
Is PreVeil FIPS validated?
A product is not “FIPS validated” just by embedding a validated module; the vendor should supply a signed letter referencing the certificate (NIST CMVP guidance).
States it has FIPS 140-3 validated cryptography.
Verified: NIST CMVP Certificate #5145, “PreVeil Cryptographic Module based on the OpenSSL FIPS Provider,” FIPS 140-3, active, Overall Level 1, “when operated in approved mode.”
The certificate-to-product/version mapping and confirmation it runs in approved mode.
Does it cover 102 of 110 controls?
Level 2 is the 110 Rev. 2 requirements; the contractor is assessed on implementation in scope.
States the platform supports compliance with 102 of the 110 controls.
The claim exists publicly; not that every buyer inherits those controls.
The Shared Responsibility / Customer Responsibility Matrix, broken into supported / shared / customer-owned.
Are outcome claims typical?
CMMC status depends on the contractor’s full implementation, scope, and assessment.
Publishes "85+ customers with perfect 110/110 scores."
The claim is published and has grown over time (earlier materials said 50+); it is self-reported.
References in your industry, with your CUI type and assessment path.
No.PreVeil substantially carries the technical controls that protect CUI inside its encrypted enclave — strongest in encryption, access control, identification, and audit for data in its system — and it accelerates your documentation. But the organizational, physical, personnel, training, and broader-system controls in NIST SP 800-171 Rev. 2 stay yours, no matter what tool you buy. “Supports 102 of 110” describes PreVeil’s capability and documentation mapping; it is not a statement that your company meets 102 controls.
The damaging admission:PreVeil’s “102 of 110” figure spans three very different things — the tool implements it, the tool helps you implement it, and we hand you a document template for it. A buyer who reads that as “PreVeil does 102 controls for me” is in for a bad day in front of an assessor. And the controls PreVeil doesn’t support directly aren’t the only ones you own; many of the “supported” controls still require your policies, your people, and your other systems.
The part that should put you at ease: For a small contractor, the controls PreVeil doescarry — encrypting CUI, controlling who can reach it, logging access, and proving all of it in documentation — are the most technically demanding and expensive part of the job. That scope reduction is the real product, and it’s a legitimately big deal. If your problem is “CUI in email and files,” PreVeil is aimed straight at it.

These calls are our editorial assessment based on PreVeil’s public documentation and NIST SP 800-171 Rev. 2. They are informed inferences, not verified control inheritance. Replace with PreVeil’s current Customer Responsibility Matrix for your specific deployment before using as assessment evidence.
The controls PreVeil doesn’t carry are where most assessments slip. If you now see that you need help with documentation ownership, endpoints, training, or the rest of your environment, that’s the readiness work, not the tool.
Does PreVeil reduce CMMC scope or take endpoints out of scope?
PreVeil can narrow your CUI boundary if — and only if — users keep CUI inside its email and file workflow. It does not automatically remove endpoints, identity systems, logs, or other connected assets from CMMC scope. Under 32 CFR Part 170, scope is defined by where CUI is processed, stored, or transmitted, plus the systems that protect those assets and any systems not isolated from them. Scope reduction is about data flow, not the vendor’s name.
If a user opens, downloads, edits, caches, screenshots, prints, syncs, or exports CUI onto a laptop, that endpoint is in the conversation. PreVeil can reduce where CUI is intended to live; you still have to prove where it actually goes. The enclave is a discipline, not a force field.

The contractors who succeed with PreVeil treat the enclave as the only place CUI is allowed to be, and they build the procedures and user habits to enforce that. The ones who struggle treat it as one option among several and let CUI scatter.
Is PreVeil FedRAMP Authorized or FedRAMP Moderate Equivalent?
Based on its public materials, PreVeil is not “FedRAMP Authorized.” It states that its Gov Community offering is “FedRAMP Moderate Equivalent” — a legitimate but more demanding pathway, and the one your assessor will scrutinize. Under DFARS 252.204-7012(b)(2)(ii)(D), any external cloud service that stores, processes, or transmits CUI must meet security “equivalent to” the FedRAMP Moderate baseline. A DoD CIO memo dated December 21, 2023 defined exactly what “equivalent” means.
That memo set a high bar. To qualify as FedRAMP Moderate Equivalent, a cloud offering must (1) demonstrate 100% compliance with the FedRAMP Moderate baseline — zero control-related POA&Ms— and (2) be assessed by a FedRAMP-recognized third-party assessment organization (a “3PAO”) using FedRAMP templates, producing a Body of Evidence. Critically, DoD also stated that equivalency is not the same as a FedRAMP Moderate Authorization. The simplest path for any cloud service is to be FedRAMP Authorized and listed on the FedRAMP Marketplace; equivalency is the alternate route, and it puts more of the validation burden on you and your assessor.
PreVeil states it has produced exactly the required Body of Evidence, attested by an independent professional source, and markets itself as the “first CSP to meet” the equivalency requirement (company-stated). Its underlying infrastructure, AWS GovCloud, carries a FedRAMP High authorization. Both points are favorable. But two things matter for you as a buyer.
First, equivalency is evaluated at your assessment, against youruse of the service. Second, a vendor’s equivalency claim is the start of your diligence, not the end of it.
The legitimate move:Get PreVeil’s 3PAO Body of Evidence in writing, confirm it shows 100% compliance with zero control-related POA&Ms, get the current Customer Responsibility Matrix, and ideally confirm a recent C3PAO has accepted PreVeil’s equivalency in a real assessment. And remember: the obligation is yours, not just the vendor’s. Under DFARS 252.204-7012 you must require and ensure your cloud provider meets the standard. Do notwrite “FedRAMP Authorized” into your own SSP unless you’ve verified that exact status.
Is PreVeil FIPS 140-3 validated?
Yes — we verified it at the source, with one precise caveat.NIST’s Cryptographic Module Validation Program (CMVP) lists the “PreVeil Cryptographic Module based on the OpenSSL FIPS Provider” under Certificate #5145 as FIPS 140-3 validated, active, Overall Level 1, “when operated in approved mode.” This is one of PreVeil’s strongest evidence points.
A FIPS validation certificate applies to a specific cryptographic module, version, and operational environment, operated in its “approved mode.” NIST’s own CMVP guidance is explicit that a product or solution does not automatically meet FIPS requirements simply by incorporating a validated module. The recommended verification is to ask the vendor for a signed letter stating that the product you’re buying incorporates the validated module, that the module provides the cryptographic services in the solution, and referencing the certificate number — then check that letter against the CMVP listing.
The accurate phrasing for your SSP is “PreVeil’s cryptographic module is FIPS 140-3 validated (NIST CMVP #5145),” paired with the mapping that confirms your deployment runs that validated module in approved mode. That’s stronger evidence than most CUI tools can show, and it’s worth confirming in writing rather than assuming.
What does PreVeil cost for CMMC?
PreVeil’s license cost is genuinely low next to a full GCC High migration — but license cost is not your CMMC budget. PreVeil is one line item. The larger, more variable costs are the readiness work for everything outside the enclave and the C3PAO assessment itself, neither of which PreVeil performs.

DoD modeled the small-entity cost of a Level 2 (C3PAO) cycle at approximately $101,752 for the assessment plus initial affirmation, and about $104,670 over the three-year cycle including two annual affirmations. That’s the government’s own estimate (CMMC Final Rule, Federal Register, Oct. 15, 2024), and it’s the number a low monthly license fee can lull you into forgetting. See our CMMC Level 2 cost breakdown for the full picture.
Want scoped numbers instead of guesswork? Cost depends on your CUI-user count, your starting maturity, and your assessment path.
PreVeil vs GCC High vs managed enclave: which path fits?
PreVeil is strongest when the goal is a narrow, lower-friction CUI email/file channel you bolt onto your existing environment. Microsoft GCC High or a managed enclave may be safer when CUI collaboration is broad, many users touch CUI, or you need integrated Teams, SharePoint, endpoint, identity, and security operations under one compliant architecture. Neither PreVeil nor GCC High is “more compliant” — PreVeil itself notes both have been used in successful assessments. The real differences are cost, speed, disruption, and how your data actually flows.
Path
Best for
Main weakness
What to verify
PreVeil
Narrow CUI email/file workflows; SMBs; supplier collaboration
User behavior and non-email/file workflows can break the model
FedRAMP-equivalency Body of Evidence, CRM, FIPS module mapping, endpoint scope
Microsoft GCC High
Broad Microsoft collaboration; many CUI users; Teams/SharePoint-heavy work
Cost and a disruptive full migration
Licensing, configuration, data residency, the surrounding endpoint/security stack
Managed enclave / VDI
Engineering-heavy or CAD/ERP CUI; high-control environments
Operational complexity; vendor dependency
Boundary design, user experience, SIEM/MFA/endpoint coverage, export-control fit
Small contractors who like PreVeil but need the rest built
Requires coordination and clear ownership
Statement of work, independence, control-owner matrix, evidence plan
The decision usually comes down to a single question: can you realistically keep CUI inside PreVeil, or will it spread through Teams, SharePoint, CAD, ERP, and endpoints anyway? If you can contain it, PreVeil’s simplicity is a genuine advantage. If you can’t, that same simplicity becomes scope risk, and a broader architecture is the safer bet. See our GCC High for CMMC guide for the full migration comparison.
What are the best PreVeil alternatives to compare?
The right PreVeil alternative depends on whyPreVeil might not fit. There’s no single “best” — there’s the architecture that matches where your CUI actually lives.
Microsoft GCC High— the default for larger or Microsoft-centric organizations that need Teams, SharePoint, and Office to handle CUI natively. More cost and migration effort; less workflow fragmentation.
Managed enclave / VDI— a hosted, locked-down workspace where CUI never leaves a controlled environment. Strong for CAD/PLM and ERP-heavy engineering shops; heavier to operate.
Secure file-transfer or data-sharing platforms — purpose-built for sending CUI to and from outside parties (vendors in this space include options like Kiteworks and Virtru). Good for narrow exchange; not a full internal-work solution.
An MSP, RPO, or MSSP— not a tool at all, but often the real answer. If PreVeil fits your data flow yet you have no one to own endpoints, identity, logging, policies, and your SSP/POA&M, the missing piece is a provider, not another product.
Not sure which architecture your CUI flow actually calls for?
Tell us where CUI lives today and what your contract requires, and we’ll show which category fits before you start collecting quotes.
What do PreVeil’s customer “110 scores” actually prove?
PreVeil’s customer stories show that some contractors have reached CMMC Level 2 successfully using its enclave. They do not prove you’ll get the same result, because a 110 score belongs to the contractor’s entire environment and program — not to the tool. PreVeil states that 85+ customers have achieved perfect 110/110 scores in C3PAO assessments (company-stated, self-reported). Read the named examples carefully, because they actually make our central point for us.

That’s not a knock on PreVeil — it’s the accurate picture, and it’s exactly the expectation you should set. The tool was necessary. It was not sufficient. No outcome here is guaranteed or “typical.”
Does PreVeil cover your SPRS score and DoD assessment obligations?
No — PreVeil doesn’t post your score or carry your assessment obligations. You still self-assess against NIST SP 800-171, post the result, keep it current, and flow requirements down to subcontractors.
If you’re required to implement NIST SP 800-171, you must have a current DoD Assessment score (not more than three years old) posted in the Supplier Performance Risk System (SPRS), the DoD’s score repository. Level 1 and Level 2 self-assessment scores, and the annual affirmations for every level, live in SPRS; Level 2 (C3PAO) and Level 3 (DIBCAC) certification results are recorded in the CMMC instantiation of eMASS and then flow to SPRS. Prime contractors must flow the requirement down to subcontractors that handle FCI or CUI, with the prime determining the appropriate level for each sub (32 CFR 170.23). An outdated or missing affirmation can flip your status to inactive and put contract eligibility at risk.
One caution on citations: these requirements were historically carried by DFARS provisions 252.204-7019 and 252.204-7020, but the 2025–2026 federal acquisition rule overhaul has been revising and renumbering them. Confirm the exact clause cited in your current solicitation rather than relying on a number you saw last year. PreVeil does not replace your SSP, your SPRS posting, your DoD Assessment, or your subcontractor flow-down.
What should you ask PreVeil before you buy? (14-question checklist)
Ask for evidence, not slogans. The safest buying process is to leave the sales call holding the exact documents your assessor, RPO, or internal compliance owner will need — before you commit to the architecture.

Don’t leave with a quote — leave with evidence. If you want a second set of eyes on what you’re being told:
Most contractors shouldn’t treat PreVeil as a solo purchase. Even a small firm typically still needs a readiness consultant or managed-compliance provider, an MSP/MSSP for the parts of the environment outside the enclave, and — when the contract requires it — a separate, independent C3PAO.
Readiness / RPO / managed-compliance provider — for CUI scoping, your SSP and POA&M, control interpretation, evidence planning, and getting assessment-ready. (An RPO is a Registered Provider Organization in the CMMC ecosystem.)
MSP / MSSP / vCISO— for endpoints, identity, logging, SIEM, vulnerability management, device hardening, and ongoing monitoring. This is the “everything outside the enclave” layer.
GRC / compliance software— as a supporting layer for evidence management and control tracking, not as the whole CMMC solution.
C3PAO— only when you’re assessment-ready or your contract requires Level 2 (C3PAO).
One rule you cannot get wrong:readiness help and formal assessment must stay separate. Under 32 CFR Part 170’s conflict-of-interest provisions, a CMMC ecosystem member that served as a consultant to prepare an organization for a CMMC assessment is prohibited from participating in that organization’s Level 2 certification assessment within three years. Don’t let a single vendor sell you remediation and your certification on the same engagement.
Need help deciding which categories you actually need?
How to decide if PreVeil belongs in your CMMC plan
Start with your CUI flow, not a vendor preference. Once you know where CUI lives, who touches it, and what assessment type your contract requires, PreVeil’s fit becomes obvious. Here’s the sequence:
Confirm your contract clause and the required CMMC level and assessment type (Level 2 Self vs Level 2 C3PAO).
Confirm whether you hold FCI only, CUI, ITAR/export-controlled data, or a mix.
Map every place CUI is received, created, edited, stored, transmitted, printed, downloaded, and archived.
Count the users who actually touch CUI.
Identify whether CUI requires Teams, SharePoint, CAD, ERP, PLM, ticketing, or project tools.
Decide whether CUI can realistically stay inside PreVeil.
Request PreVeil’s evidence pack (Body of Evidence, CRM, FIPS mapping, SSP support).
Map PreVeil-supported, shared, and customer-owned controls.
Validate the architecture with a readiness advisor or a qualified internal lead.
Pilot with real users, lock procedures, then engage a C3PAO only when you’re ready and the contract requires it.

CUI is mostly email/file exchange
Evaluate PreVeil seriously
CUI lives in Teams/SharePoint
Compare GCC High or a stronger enclave
CUI is engineering/CAD-heavy
Compare a managed enclave or VDI
You don’t know where CUI lives
Do scoping before selecting any tool
Your contract requires Level 2 (C3PAO)
Separate readiness from assessment now
Your deadline is inside 90 days
Focus on scope containment and evidence triage
Timing reality: CMMC requirements began entering DoD contracts on November 10, 2025(Phase 1 — Level 1 and Level 2 self-assessments). Phase 2 begins November 10, 2026: DoD intends to require Level 2 (C3PAO) certification as a condition of award for applicable contracts. Phase 3 (November 10, 2027) extends Level 2 (C3PAO) to all applicable contracts and introduces Level 3 (DIBCAC) assessments. With authorized C3PAO capacity still small relative to the tens of thousands of contractors that will need assessment, scheduling takes months. If your contracts will face Phase 2, the time to decide your architecture is now, not next fall.
What we actually verified
Verified against primary sources (checked ):
CMMC Level 2 maps to the 110 requirements of NIST SP 800-171 Rev. 2 — 32 CFR Part 170.
The phased rollout, the November 10, 2025 effective date of the DFARS acquisition clause, and the Phase 2/Phase 3 wording, against the DoD CIO CMMC program page and 32 CFR 170.3(e).
The FedRAMP Moderate equivalency standard (100% compliance, zero control-related POA&Ms, 3PAO Body of Evidence) and the rule that equivalency does not equal FedRAMP Authorization — DoD CIO memo, December 21, 2023.
NIST CMVP Certificate #5145 (FIPS 140-3, “when operated in approved mode”) for PreVeil’s cryptographic module — verified on the NIST CMVP validated-modules listing.
The DoD small-entity Level 2 (C3PAO) cost estimate (~$101,752 / ~$104,670) — CMMC Final Rule, Federal Register, Oct. 15, 2024.
The SPRS / DoD Assessment substance and subcontractor flow-down (noting the 2025–2026 acquisition-rule revisions).
Reviewed and labeled company-stated:PreVeil’s “supports 102 of 110 controls,” “85+ perfect 110 scores,” “first CSP to meet FedRAMP equivalency,” AWS GovCloud hosting, ITAR 120.54 alignment, Compliance Accelerator documentation, and published pricing — all attributed to PreVeil and flagged for your verification.
Reviewed for independent perspective:TechRadar’s hands-on review (praised the security and M365-overlay approach; flagged manual plug-in installation and no PGP-based encryption) and G2’s review profile (modest review volume, generally positive, with some users noting collaboration friction from the recipient-account requirement).
What we did not do:We did not deploy PreVeil in a test environment, observe a live assessment, receive PreVeil’s private evidence package, or accept payment from PreVeil for this analysis.
What we verified about PreVeil (named-provider summary)
Provider category:
CUI enclave / secure collaboration software (encrypted email and file sharing); GRC documentation support. Not a C3PAO, RPO, or assessor.
Cyber AB Marketplace:
Not applicable to PreVeil as a software vendor; the Cyber AB Marketplace lists assessors and consultants. Verify any partner assessor’s status there directly.
None in connection with this review; we were not paid or sponsored by PreVeil, and this page routes to a neutral matching form, not to PreVeil.
Evaluation depth:
Public-source profile and buyer’s guide — public materials, independent reviews, and primary regulatory sources. No hands-on test, no private evidence package, no paid engagement.

What we could not verify:
PreVeil’s full FedRAMP-equivalency Body of Evidence, its current private Customer Responsibility Matrix, individual customer assessment files, and any outcome’s typicality.
No single product is “CMMC compliant” on its own. PreVeil can support a CMMC Level 2 program by protecting CUI in an encrypted enclave and accelerating documentation, but a contractor’s CMMC status depends on its full scope, implementation, evidence, assessment type, and annual affirmation. The organization is assessed, not the tool.
Is PreVeil a C3PAO?
No — and it doesn’t claim to be. PreVeil is a software vendor (a CUI enclave for encrypted email and file sharing) that markets itself as a tool used alongside C3PAOs; it cannot perform your certification assessment. Readiness help must be kept distinct from formal assessment.
Is PreVeil FedRAMP Authorized?
Based on its public materials, PreVeil is not FedRAMP Authorized; it states its Gov Community offering is FedRAMP Moderate Equivalent and is hosted on AWS GovCloud (which is FedRAMP High authorized at the infrastructure layer). Equivalency is a legitimate pathway under DFARS 252.204-7012, but DoD says it does not confer FedRAMP Authorization, and your assessor evaluates it — so request and validate the Body of Evidence.
Is PreVeil FIPS 140-3 validated?
Yes, at the module level. NIST’s Cryptographic Module Validation Program lists PreVeil’s module under Certificate #5145 (FIPS 140-3), based on the OpenSSL FIPS Provider, as active “when operated in approved mode.” Confirm your deployment runs that validated module in approved mode and ask PreVeil for a signed letter mapping the certificate to your product version.
Does PreVeil replace GCC High?
Sometimes it can avoid the need for GCC High, and sometimes it cannot. The deciding factor is whether you can keep CUI inside PreVeil rather than spreading it through Teams, SharePoint, CAD, ERP, and endpoints. SMBs with narrow CUI flows often choose PreVeil; large Microsoft-centric organizations frequently choose GCC High.
Can I use PreVeil with Microsoft 365 Commercial?
Yes — that’s a core part of the model. PreVeil overlays M365 Commercial and handles CUI, while M365 continues to serve non-CUI work. But it only works if CUI is genuinely kept out of M365 Commercial workflows that aren’t in your compliant boundary, which requires a real data-flow diagram and user discipline.
Does PreVeil take endpoints out of scope?
Not automatically. If endpoints process, store, transmit, display, cache, or protect CUI, those endpoints remain in scope. PreVeil reduces where CUI is intended to live; you still must prove where it actually goes.
What does “PreVeil supports 102 of 110 controls” mean?
It’s a company-stated capability and documentation claim, not proof that your organization meets 102 controls. Request the Shared Responsibility / Customer Responsibility Matrix and map each control to product-supported, shared, and customer-owned, then build your evidence accordingly.
How much does PreVeil cost for CMMC?
PreVeil publishes Business at about $30 per user per month, Gov Community as custom, and a PreVeil Pass bundle starting around $450 per month for three users (company-stated; verify in a quote). PreVeil is one line item; readiness work and a separate C3PAO assessment — which DoD models near $101,752 for a small entity — are usually the larger costs.
Does PreVeil handle my SPRS score?
No. You still self-assess against NIST SP 800-171 and post a current score (not more than three years old) in the Supplier Performance Risk System (SPRS), with annual affirmations and subcontractor flow-down. PreVeil doesn’t replace your SSP, your SPRS posting, or your DoD Assessment obligations.
Do I still need a C3PAO if I use PreVeil?
Only if your contract requires Level 2 (C3PAO). The acquisition rules let the contracting officer specify the required level and assessment type, and Level 2 (C3PAO) assessments must be performed by an authorized C3PAO that is separate from your readiness help.
Is PreVeil good for small contractors?
It can be — it’s designed for exactly that buyer, especially when only a subset of users handles CUI and email/file workflows dominate. Confirm your data flow, your evidence pack, and the total program cost beyond the license.
