At some point, a bigger customer's procurement team sends your startup a security questionnaire, or flatly asks for a SOC 2 report before they'll sign. If you're a five-person team with no dedicated compliance hire, the usual advice — "just use Vanta" — skips over the actual problem: even with the best dashboard, someone still has to know which controls apply, what evidence an auditor actually wants, and how to talk to the auditor in the first place. The tools below are built specifically for that first-time situation, not for a company that already has a compliance program and just wants to keep it running.
The short version: three of these pair you with an actual human who has done SOC 2 audits before (Probo, SecureSlate, ComplyJet) — good if you have zero compliance knowledge in-house. Two are flat-fee, AI-assisted self-serve software built for small teams (AuditBadger, Klaay) — good if you're comfortable running the process yourself with software doing the busywork. One is free and open source (Openlane) — good if you'd rather self-host than pay anyone. And one (Secureframe) is the closest thing to a safe, recognized default if a customer's procurement team is going to double-check the vendor name.
1. Probo — a dedicated compliance officer, not just a dashboard
Most compliance software assumes you already know what to do with it. Probo's difference is pairing the automation with an actual dedicated compliance officer who manages the process end-to-end — useful when your team has zero in-house compliance expertise and would otherwise be Googling "what evidence does a SOC 2 auditor want" at 11pm. It covers SOC 2 Type 1 & 2, ISO 27001, ISO 27701, ISO 42001, GDPR and HIPAA, with Slack-triggered workflows and branded trust pages. It's Y Combinator-backed with an open-source deployment option, and counts Ahrefs and Typebot among its customers.
Watch out for: pricing isn't published, and the service-plus-software model likely costs more than pure self-serve software.
Pick Probo if: you want an actual person managing the process, not just a checklist app.
2. SecureSlate — fixed price, guided by a former auditor
SecureSlate pairs an AI platform for evidence discovery with a dedicated compliance lead who has real auditor experience — and agrees the price with you upfront, before work starts, instead of the unpredictable hourly billing a compliance consultant usually charges. It covers SOC 2, ISO 27001, HIPAA, and notably ISO 42001 (AI management systems) — a framework almost no competitor in this list supports, relevant if your product itself uses AI. Pricing starts around $284/month with no surprise hourly add-ons.
Watch out for: the guided model costs more than pure self-service, and exact pricing still needs a consultation.
Pick SecureSlate if: you want fixed, predictable pricing and a former auditor walking you through it — and ISO 42001 matters to you.
3. ComplyJet — cheapest way to bundle software and a real auditor
ComplyJet automates evidence collection through 350+ real-time integrations, then bundles access to a vetted auditor network so you're not separately hunting for someone accredited to actually sign off on your audit. It also throws in a fractional "vCISO" option for startups that need security leadership without a full-time hire. The company positions itself at roughly half the price of legacy vendors — Core tier is $4,000/year for one framework (up to 50 employees), Plus is $6,400/year for two frameworks; separate audit services start at $3,000.
Watch out for: published tiers cap out at 50 employees — bigger teams go custom — and audit services are billed on top of the subscription, not included in it.
Pick ComplyJet if: you want the lowest all-in price for software plus a real auditor relationship, and you're under 50 employees.
4. AuditBadger — flat fee, unlimited users, built by actual auditors
AuditBadger was built by people who used to sit on the other side of the table as working auditors, so the checklist — controls, evidence, policies, risk tracking — reflects what an auditor actually asks for, rather than a generic compliance template. It's the only tool here with genuinely flat, seat-free pricing: $250/month covers SOC 2 and ISO 27001 together, unlimited users, no annual lock-in, no sales calls. Support comes directly from the founders.
Watch out for: only two frameworks are covered (no HIPAA, PCI-DSS, or FedRAMP), and as a newer player its integration library is smaller than the established names.
Pick AuditBadger if: you specifically need SOC 2 + ISO 27001, want a flat monthly number with no seat math, and don't want to talk to sales.
5. Klaay — the cheapest entry point, fully AI-driven onboarding
Klaay targets exactly the company that finds a $10,000–$30,000/year compliance consultant absurd for a five-person startup: fully AI-driven onboarding, autonomous agents that flag compliance gaps continuously instead of waiting for a quarterly review, and 100+ integrations to pull evidence automatically. Pricing scales with headcount — Starter is $149/month for up to 10 employees, Professional $299/month for up to 30, Advanced $499/month removes the cap.
Watch out for: the per-employee add-on charge means costs climb faster than AuditBadger's flat fee once you're past 10-30 people.
Pick Klaay if: you're a very early-stage team (under 10-30 people) and want the lowest possible starting price with the process handled almost entirely by AI.
6. Openlane — free, open source, self-hosted
Openlane offers a genuinely different path: the same automated evidence-collection idea as Vanta or Drata, but as Apache 2.0-licensed, self-hostable software — free, if you're willing to run it yourself. It covers 12+ frameworks (SOC 2, ISO 27001, GDPR, HIPAA, PCI-DSS, NIST 800-53, ISO 42001), with native integrations for AWS, Azure, GCP, GitHub, Google Workspace, Slack, and Entra ID, plus a public Trust Center. Because it's open source, an auditor (or you) can actually inspect how evidence gets collected instead of trusting a SaaS black box.
Watch out for: a much smaller community than the paid leaders (under 300 GitHub stars), no dedicated audit/auditor relationship built in, and self-hosting means the reliability of the system your auditors will scrutinize is now your responsibility.
Pick Openlane if: budget is the hard constraint, you're comfortable self-hosting, and you already know how to find your own auditor.
7. Secureframe — the safe, recognized default if procurement checks the vendor name
Secureframe is the closest thing on this list to "the Vanta/Drata of this list" — automated evidence collection connected directly to your cloud infrastructure, continuously checking your actual configuration against SOC 2, ISO 27001, HIPAA, PCI DSS, GDPR, CCPA, NIST, and CMMC 2.0 (relevant if you sell to defense contractors). Three tiers (Fundamentals, Complete, Defense) add third-party risk management, questionnaire automation, and SSO/SCIM as you go up. The company backs it with 30+ in-house compliance experts.
Watch out for: pricing isn't published anywhere, and it competes in the most crowded part of this market (Vanta, Drata, Sprinto, Thoropass, Trustero) without an obvious differentiator on the site itself.
Pick Secureframe if: a customer's procurement team is going to look up whichever vendor you picked, and you'd rather show them a name they already recognize.
Which one should you actually pick?
| Tool | Model | Starting price | Best for |
|---|---|---|---|
| Probo | Software + dedicated compliance officer | Not published | Zero in-house compliance knowledge |
| SecureSlate | Software + ex-auditor guide | ~$284/mo | Fixed pricing, ISO 42001 support |
| ComplyJet | Software + bundled auditor network | $4,000/yr | Cheapest all-in software + auditor |
| AuditBadger | Flat-fee self-serve software | $250/mo, unlimited users | SOC 2 + ISO 27001, no seat math |
| Klaay | AI-driven self-serve software | $149/mo (≤10 employees) | Very early-stage, lowest entry price |
| Openlane | Free, open source, self-hosted | Free (self-hosted) | Budget-constrained, technical team |
| Secureframe | Established SaaS platform | Quote required | Recognized name for procurement |
If you genuinely have no idea where to start, pay for the human — Probo, SecureSlate, or ComplyJet will keep you from wasting weeks on a wrong framework or missing evidence. If you're comfortable driving the process yourself and just want software that doesn't cost a consultant's salary, AuditBadger's flat $250/month or Klaay's $149/month starting tier both beat the unpublished-pricing crowd on transparency alone. And if the only thing standing between you and a signed deal is a procurement team that's never heard of any of these names, Secureframe (or the already-covered Vanta/Drata) buys you instant recognition — at the cost of an unpublished quote.
