SOC 2 Readiness AssessmentCompare service firms
SOC 2 Readiness FirmsPenetration Testing FirmsvCISO FirmsISO 27001 ConsultantsCompliance ConsultantsAll Service FirmsWe track 63 SOC 2 auditors with documented B2B SaaS experience, Type 2 from $7K over 1 to 12 months. Most firms can audit SaaS. Far fewer understand multi-tenant isolation, CI/CD change management, or matching your Availability scope to your SLAs.
Updated / Different vertical? Healthcare · FinTech · AI · Startups
Seven picks for the SaaS audit scenarios buyers actually run — GRC-bundled, Vanta-native, deal-closing Type 1 in 30 days, Drata-native, multi-framework, Big 4 alternative, and mid-market. Each names one firm with the qualifier that earned the pick.
Thoropass is the typical pick for B2B SaaS that wants the GRC platform and the CPA audit on one contract — multi-tenant architecture review, Availability TSC scoping, and shared evidence across SOC 2 + ISO 27001 + HIPAA + PCI under a single engagement, with fixed-fee pricing 25–50% below traditional firms.
Prescient Security is the pick for SaaS already on Vanta — deep Vanta partner, Slack-based same-day audit communication, no on-site visits, and SOC 2 + ISO 42001 bundled for AI-first SaaS. The Vanta-native default from Series A through growth stage.
Johanson Group is the pick when an enterprise prospect is gating a SaaS contract on a SOC 2 report — fixed-fee Type 1 in 1–3 weeks from an accredited CPA, with the Type 2 observation period starting in parallel so the upgrade arrives in a single cycle. The fastest credentialed path to "we have SOC 2."
Sensiba LLP is the pick for Drata-native VC-backed SaaS closing the first enterprise contract — Drata, Vanta, Secureframe, and Sprinto partnerships, SOC 2 + ISO 27001 in one 4–8 month engagement, and ISO 42001 available for AI governance.
A-LIGN is the pick for enterprise SaaS that needs SOC 2 alongside HITRUST, FedRAMP, or PCI — one of the highest-volume US SOC 2 practices bundles every major framework under one engagement, and procurement teams know the brand on the cover of the report.
Schellman is the pick for SaaS whose enterprise buyers want a recognised brand on the SOC 2 report but who do not specifically require a Big 4 letterhead — Top 50 CPA, deep cloud and tech-services practice, and reports that satisfy Fortune 500 procurement without Big 4 rates.
Armanino LLP is the pick for mid-market SaaS ($10M–$500M revenue) that wants tech-industry fluency without a Big 4 budget — bundled audit-and-tax for PE-backed companies, West Coast presence, and SOC 2 + ISO 27001/27701 for international expansion.
All firms have SaaS listed as a core industry vertical with documented experience auditing multi-tenant and cloud-native products. Sorted by editorial rank — featured firms carry a left rule. Pricing in USD, timelines in months.
Best for · First-time SOC 2 / ISO 27001 / HIPAA / PCI / HITRUST seekers (under 200 employees) who want one vendor handling both the GRC platform and the audit, eliminating the handoff between Vanta/Drata-style automation and a separate CPA firm.

SOC 2 lets you choose which Trust Service Criteria to include. Security is mandatory. The right additions for SaaS depend on your product, customer contracts, and what enterprise security teams will ask for.
Most B2B SaaS start with Security + Availability. Adding Confidentiality or Privacy is common at growth stage when enterprise procurement teams add data-handling requirements to security questionnaires.
| TSC | What it covers | SaaS relevance |
|---|---|---|
| Security (CC) | Logical access, encryption, monitoring, incident response | Required — always in scope |
| Availability | Uptime, performance monitoring, disaster recovery | Required if you have SLAs |
| Confidentiality | Data classification, NDA enforcement, data destruction | Add if handling sensitive business data |
| Processing Integrity | Accurate, complete, and authorised data processing | Add for FinTech, payments, data pipelines |
| Privacy | PII collection, consent, data subject rights | Add for end-user PII at scale or EU customers |
Four control areas where the wrong auditor either generates findings against your engineering culture or underscopes risks that enterprise security buyers catch in security review.
Whether you run shared-schema with row-level security, siloed databases per tenant, or a hybrid — the auditor evaluates your isolation model before scoping begins. SaaS-specialised firms flag architectural risks before fieldwork and document tenant separation in a way enterprise security teams accept on review.
If you've committed to uptime in a customer MSA, enterprise security reviewers look for Availability coverage. Most first-time audits scope only Security — fine for a first deal, not for a SaaS with contractual uptime. Adding Availability after the first audit means another engagement and another observation period.
SaaS-experienced auditors evaluate GitHub PR approvals, deployment gates, and feature flags against SOC 2 change-management requirements without asking you to manually document 500 releases. Required branch protection, code reviews, and deployment approval gates usually satisfy controls without changing how fast you ship.
Your SOC 2 scope includes how you evaluate, monitor, and contract with every vendor that touches customer data — AWS, Stripe, Twilio, Datadog. SaaS-specialised firms bring vendor tiering templates that reduce the first-time inventory build from weeks to days and know which subprocessors require their own SOC 2 reports vs basic security assessments.
After your first Type 2, SaaS-experienced auditors reduce renewal effort by 50–70% through automated evidence collection — pulling from your GRC platform, CI/CD logs, and cloud monitoring rather than requiring manual evidence runs. If your year-one auditor can't articulate how they'll streamline year two, ask before signing.
Four lines: auditor fees, GRC platform, security tooling, internal engineering time. Year-two renewals typically drop to $12–30K in auditor fees with 50–70% less internal time once evidence collection is automated.
$15–50K
$8–15K
$5–12K
150–300 hrs
Five questions specific to SaaS architecture, TSC selection, and ongoing compliance — separate from the general first-audit questions on the startups page.
Almost certainly yes. If you've committed to uptime in a customer MSA or SaaS agreement, enterprise security reviewers will look for Availability coverage in your SOC 2 report. Without it, you'll spend more time answering security questionnaire exceptions than the TSC would have cost to add. The practical threshold: if any customer contract mentions uptime, SLAs, or business continuity obligations, scope Availability from the start. Adding it after your first audit means a separate engagement and another observation period.
Auditors evaluate how tenant data is stored, how access is partitioned, and what prevents one tenant from accessing another's records. Separate-database architectures are the cleanest to audit. Shared-schema with row-level security (RLS) is defensible but requires query-level evidence that RLS is consistently enforced. Shared-schema without RLS will generate findings. In fieldwork, auditors test logical access controls, database-level separation, and application-layer permissions — sampling both the design and operational consistency. If your architecture is still in flux, flag it before selecting an auditor; scoping assumptions drive everything downstream.
Change management gets tested at the process level, not the commit level. Auditors evaluate your change approval workflow (required PR reviewers), deployment controls (production gating), and rollback procedures. They sample a set of changes and verify controls operated consistently — not every deploy. What breaks CI/CD audits: no required reviewers on PRs, direct pushes to main, or environment promotion without approval gates. What works: enforced branch protection, required code reviews, deployment approval in your CI pipeline. Most modern engineering setups satisfy these controls without changing how fast you ship.
Standard practice is to share under NDA — available to customers and prospects who request it, not posted publicly. Publishing the full report creates risk: if a finding appears, it's visible to everyone. What works better is a trust center page (Vanta, Drata, and Secureframe all offer this) showing your SOC 2 status without exposing the full report. This lets prospects self-serve your compliance posture during evaluation and reduces the security questionnaire load on your team. Ask your auditor whether they'll provide a summary letter or executive overview for sales use without distributing the full attestation.
Your subprocessor scope doesn't mean every vendor gets audited — it means you document and manage vendor risk for vendors that process or store customer data. The framework: (1) maintain a vendor inventory with data classification, (2) collect SOC 2 reports from critical subprocessors — AWS, Stripe, Twilio, Datadog all publish theirs, (3) document your annual vendor review cadence. Auditors test whether your vendor risk management process exists and runs consistently, not whether every vendor is perfectly secure. SaaS-specialized auditors typically provide tiering templates that reduce the first-time inventory build from weeks to days.
If you're pre-Series A or building AI features into your SaaS, the vertical pages narrow scope further. The cost guide drills into per-stage benchmarks, and the directory and combined-framework lists widen the comparison.
Firms that handle SOC 2 + ISO 42001 and model versioning as change management.
Type 1, Type 2, and annual renewals — with SaaS benchmarks by stage.
Firms that run both engagements together when EU buyers want the certificate too.
The broader ranked auditor list. Compare it before narrowing to SaaS specialists.
Every firm we track, filterable by price, timeline, GRC platform, and company size.
SOC 2 attestation vs consulting · SOC 2 reports must be issued by licensed Certified Public Accountants under AICPA standards (SSAE 18). Many GRC vendors offer "SOC 2 preparation" but cannot issue the attestation report itself.
Verify credentials · confirm AICPA peer-review status and SSAE 18 attestation authority before signing. SaaS-specialised firms typically publish their AICPA peer-review report on request.
Disclaimer · pricing estimates and timelines shown are approximations based on publicly available information and user-submitted data. Actual costs and timelines vary based on company size, complexity, and scope.
