The Real Difference: What Your Evidence is Built on
Take one ordinary SOC 2 control: when an employee leaves, their access is revoked within 24 hours. Every platform here can produce evidence for it. What differs is what that evidence shows. Vanta and Drata automate evidence by continuously checking that controls are configured correctly: the account was disabled, the access list was reviewed, encryption is on. Thoropass adds its own auditor reviewing that same configuration evidence. UnderDefense MAXI Compliance AI pulls evidence from an environment it already monitors around the clock, so that evidence shows the control actually operating in a live environment, across the period an auditor reviews.

Control tested: when an employee leaves, their access is revoked within 24 hours.
| A standalone tool (Vanta, Drata, Thoropass) | UnderDefense MAXI Compliance AI |
| Connects to your HR system and identity provider Confirms the account was disabled inside the 24-hour window Timestamps the change as evidence Result: proves the account was switched off on the day the evidence was pulled | Runs that same checkWatches the monitored environment around the clockConfirms no access came from that account after the person left, from the infrastructure activity it continuously monitors. Result: shows how the control behaved in production across the audit period |
At audit and in customer security reviews, “the account was disabled” and “no unauthorized access actually happened” are different questions. Reviewers increasingly ask the second, and evidence from a monitored environment answers it directly. That works because UnderDefense MAXI Compliance AI monitors your connected infrastructure around the clock through your existing stack, so its evidence reflects live activity across the period an auditor reviews.
Is a Compliance Automation Platform Enough for SOC 2?
For many teams, yes. If you need SOC 2 to close deals and you run a standard SaaS stack, Vanta or Drata will get you certified, and that may be all you ever need.
It starts to matter when the stakes move past the certificate. Enterprise security reviews increasingly ask how a control actually operated over the period, and regulated industries expect the same. If no one is actively watching the environment your evidence describes, a configuration snapshot is all you can show. That is where a Vanta or Drata alternative built on live infrastructure monitoring, or a vendor that includes human audit support, earns its place.
Pricing
On Vanta vs Drata pricing, and Thoropass and UnderDefense too: none of these platforms publish list prices, so every deal is quote-based. The ranges below are directional benchmarks from Vendr buyer data and 2026 pricing analyses, not quotes.
| Vanta | Drata | Thoropass | UnderDefense MAXI Compliance AI | |
| Pricing model | Quote-based, billed on employee headcount | Quote-based, tiered plans | Quote-based, platform and audit in one contract | Quote-based, scoped per engagement |
| Reported annual range | ~$10K to $110K+ | ~ $7.5K to $100K+ | ~$20K to $60K+ all-in | Custom, scoped to frameworks and environment |
| Median (Vendor) | ~$20K | ~$25K | ~$30K | Flexible, competitive quote |
| Audit fees | Separate, bring your own auditor | Separate, bring your own auditor | Included, in-house CPA audit | Partner auditors and in-house experts included |
| After certification | Renews yearly, tends to climb | Renews yearly, added frameworks ~$1,500 each | Renews yearly with the bundled audit | Steps down after you certify |
UnderDefense MAXI Compliance AI is the youngest option here, but that comes with advantages the older platforms do not have:
- Evidence is drawn from an environment under 24/7 infrastructure monitoring, so it reflects how controls actually operate
- Your first framework, in-house experts, and partner auditors are included
- The price steps down after you certify, so the first year carries the weight and later years cost less
- It stays open: it works alongside the security stack you already run, the evidence and policies you build remain yours.
- 80% of paperwork effort automated
- 100% of compliance audits are passed successfully
- 2x faster time-to-compliance (vs. traditional audit)
- Rated 4.9/5 on Gartner Peer Insights
Which Compliance Platform Should I Choose?
Choose Vanta if you want the most proven platform and the widest integrations, and your team is comfortable self-serving.
Choose Drata if you are scaling fast, engineering-led, and want the cheapest way to add frameworks.
Choose Thoropass if you want one vendor for both the software and the audit and are fine staying with their auditor.
Consider UnderDefense MAXI Compliance AI as a Vanta or Drata alternative when you want compliance evidence tied to live infrastructure monitoring, human audit support included, and a price that steps down after you certify.
TLDR: All four can get you certified. The difference is what your evidence proves once you are there.
