If you handle Controlled Unclassified Information on a DoD contract, you need CMMC Level 2 certification. The question most contractors ask next is: what software do I use to get there?
This guide covers the platforms that come up most often in the DIB market, what each one actually does well, and what you need to understand before you choose one. The list includes both purpose-built CMMC tools and general GRC platforms that have added CMMC modules. They are not equivalent.
How we ranked these platforms
Every platform on this list was evaluated against the same criteria. These are the things that actually determine whether a tool helps you pass a C3PAO assessment, not just check boxes on a spreadsheet.
| Criterion | Why it matters |
|---|---|
| CMMC-specific design | Built for NIST SP 800-171 and the CMMC assessment methodology, not repurposed from SOC 2 or ISO 27001 |
| All 110 requirements | Partial coverage leaves gaps that surface during assessment |
| SSP generation | The SSP is the primary document your C3PAO assessor evaluates; it must be substantive, not templated |
| SPRS score tracking | Contractors must submit a current SPRS score; real-time tracking is essential for maintaining and reporting it accurately |
| Deployment model | Cloud deployments may expand your CMMC boundary if compliance data qualifies as CUI |
| Ongoing compliance support | Certification is valid for 3 years with annual affirmations; the tool has to work beyond initial assessment |
| Small contractor fit | Enterprise GRC tools often require a dedicated compliance team to operate effectively |
Top CMMC compliance software platforms in 2026
Five platforms consistently come up when small DIB contractors are evaluating their options. Here is what each one actually delivers.
#1 — 1TEN (Best for small DIB contractors)
1TEN is the only purpose-built, air-gapped CMMC Level 2 compliance appliance designed exclusively for defense contractors. It deploys as an on-premises hardware appliance inside your network, with no cloud dependency and no data leaving your environment.
Every module maps directly to the CMMC Level 2 control set. There are no bolt-on CMMC modules and no framework crosswalks to manage. The platform was built from the ground up around NIST SP 800-171 Rev 2 and the CMMC assessment methodology.
- All 110 NIST SP 800-171 requirements across all 14 domains
- Real-time SPRS score calculation with point-weight visibility
- Automated SSP generation from your environment data
- Policy Generator producing all 14 domain policies
- POA&M tracking with remediation timelines
- Evidence Manager with control linkage
- Security awareness training with completion tracking
- Asset Inventory, Risk Register, Compliance Calendar
- Visitor log, supplier management, and more across 23 modules
- Air-gapped deployment: compliance data never leaves your network
- No CMMC boundary expansion from cloud vendor infrastructure
- Veteran-owned, built by people with DIB experience
- Single-platform coverage eliminates tool sprawl
- No per-user or per-module pricing surprises
- Works for organizations with no dedicated IT compliance staff

#2 — Vanta (Best for multi-framework GRC)
Vanta is a cloud-based GRC platform originally built for SOC 2 automation. It has added CMMC support through a framework module. It is well-known in the tech startup market and is one of the most commonly evaluated tools when defense contractors start their search, largely because of its name recognition from the commercial compliance space.
Vanta works well for organizations that need to manage multiple compliance frameworks simultaneously. If you need SOC 2 and CMMC, Vanta reduces the overhead of managing them as separate efforts. For contractors who only need CMMC, the added complexity of a multi-framework GRC tool is not an advantage.
- Polished interface with strong automation integrations
- Good fit for organizations managing multiple frameworks
- Large vendor ecosystem with pre-built integrations
- Established support and documentation
- Cloud-based: compliance data stored on Vanta infrastructure
- CMMC is a bolt-on module, not the core design
- SSP output requires significant manual customization
- SPRS scoring is not a native feature
- Pricing scales with users and integrations
#3 — Drata (Best for enterprise GRC teams)
Drata is another cloud-based GRC platform with strong SOC 2 roots that has expanded into CMMC. It competes directly with Vanta and offers similar multi-framework capabilities. Drata's interface is well-regarded, and its monitoring and evidence collection automation is genuinely useful for organizations with the IT infrastructure to take advantage of it.
Like Vanta, Drata is better suited to organizations with a dedicated compliance function than to small contractors managing CMMC alongside their core business. The platform assumes a level of compliance program maturity that most small DIB contractors are still building.
- Strong continuous monitoring and evidence automation
- Clean reporting and audit trail capabilities
- Good fit for organizations with existing cloud infrastructure
- Active development with regular feature releases
- Cloud-based with the same boundary expansion concerns as Vanta
- CMMC added as a framework module, not native design
- Requires dedicated compliance staff to get full value
- SPRS scoring and POA&M workflows are not primary features
#4 — PreVeil (Best for CUI-secure email and file sharing)
PreVeil is purpose-built for defense contractors, but it solves a different problem than the other tools on this list. PreVeil is an encrypted email and file sharing platform that uses end-to-end encryption to protect CUI in transit and at rest. It addresses specific NIST SP 800-171 requirements around CUI handling, particularly in the Access Control and System and Communications Protection domains.
PreVeil is not a full CMMC compliance platform. It does not generate SSPs, track SPRS scores, manage POA&Ms, or cover all 110 requirements. It is a CUI security tool that satisfies a subset of controls. Contractors using PreVeil still need a separate compliance management platform for the rest of their program.
- Purpose-built for DIB CUI handling requirements
- Strong encryption model for email and file sharing
- Addresses specific CMMC controls in AC and SC domains
- Relatively straightforward deployment for end users
- Not a compliance management platform — covers a subset of controls
- No SSP generation, SPRS scoring, or POA&M management
- Requires a separate tool to manage the full 110-requirement control set
- Best understood as a CUI handling solution, not a compliance solution
#5 — Sprinto (Best for SaaS-heavy environments)
Sprinto is a cloud-based compliance automation platform that has grown quickly in the SMB market. It supports multiple frameworks including CMMC and integrates with a wide range of SaaS tools common in tech-forward organizations. If your environment is heavily SaaS-based, Sprinto's integrations can reduce the manual work of evidence collection.
For traditional defense contractors with on-premises infrastructure, Sprinto's integrations are less relevant. The platform is cloud-based, carries the same boundary expansion considerations as Vanta and Drata, and is not designed specifically around the CMMC assessment methodology or DIB compliance requirements.
- Wide SaaS integration library for automated evidence collection
- Competitive pricing for small organizations
- Fast onboarding compared to larger GRC platforms
- Cloud-based with associated boundary risks
- Not designed around the CMMC assessment methodology
- Less DIB-specific than the other platforms on this list
- SPRS scoring not a native feature

What compliance software cannot do
No software certifies you. Software manages documentation, tracks your posture, generates required artifacts, and prepares you for the questions a C3PAO assessor will ask. It does not implement security controls on your behalf.
Control sufficiency — whether your implementation of a given requirement actually meets the standard — requires human judgment. A Registered Practitioner can assess whether your MFA configuration, access control model, or incident response procedure actually satisfies the requirement as written. Software records what you have; an RP tells you whether what you have is enough.
The right model for most small contractors is software plus targeted RP engagement. Software handles the operational compliance program. The RP handles the judgment calls. Trying to replace one with the other usually produces either documentation that fails assessment or consulting bills that never end.
Frequently asked questions
For small DIB contractors, the best CMMC software is purpose-built for CMMC Level 2, not repurposed from SOC 2 or ISO frameworks. 1TEN is the only air-gapped appliance built exclusively for defense contractors, covering all 110 NIST SP 800-171 requirements without cloud dependency or boundary expansion risk.
You likely need both, but in different roles. Software handles documentation, SSP generation, SPRS scoring, evidence collection, and ongoing tracking. A Registered Practitioner handles control sufficiency questions and assessment strategy. Software without RP input can produce documentation that fails assessment. RP input without software produces documentation that is difficult to maintain.
Yes. If a cloud-based tool stores your SSP, policies, or evidence artifacts and that content qualifies as CUI, the vendor's infrastructure may fall within your CMMC assessment boundary. An on-premises or air-gapped deployment eliminates that risk. This is one of the most overlooked procurement decisions small contractors make.
GRC platforms are general-purpose governance tools originally built for SOC 2, ISO 27001, or HIPAA. Most have added CMMC modules. CMMC-specific software is built from the ground up around NIST SP 800-171 and the CMMC assessment methodology, with features like SPRS scoring, C3PAO-ready SSP export, and CMMC domain-specific evidence workflows that general GRC tools handle as afterthoughts.
Pricing varies significantly by platform and deployment model. Cloud-based GRC tools typically charge per user per month, with total annual costs for a small contractor often running $10,000 to $30,000 or more depending on user count and feature tier. Purpose-built appliance platforms like 1TEN use different pricing models. Contact vendors directly for current pricing, and factor in the total cost of ownership including implementation, training, and ongoing support.
