SOC 2 Readiness FirmsPenetration Testing FirmsvCISO FirmsISO 27001 ConsultantsCompliance ConsultantsAll Service FirmsWe track 58 SOC 2 auditors with documented B2B SaaS experience, Type 2 from $7K with fieldwork from 1 week. Most firms can audit SaaS. Far fewer understand multi-tenant isolation, CI/CD change management, or matching your Availability scope to your SLAs.
Free and anonymous. At least 3 quotes in 48 hours. One call, not five.
For most SaaS companies, Thoropass, Prescient Security, and Johanson Group are the strongest starting points, with Type 2 entry pricing from $15K and fieldwork from 1 to 9 weeks. We track 58 SaaS-focused firms; compare the audit model, platform fit, and enterprise buyer deadline before choosing.
Six picks for the SaaS audit scenarios buyers actually run: economical boutique, GRC-bundled, deal-closing Type 1 in 30 days, Drata-native, multi-framework, and Vanta-native. Each names one firm with the qualifier that earned the pick.
Zero Day CPA is the value pick for a first SaaS SOC 2 from a credentialed boutique: audit managers with 5+ years at a Big Four or major national firm, so startups get enterprise-grade rigor at fixed pricing from around $5K on a 2 to 6 week turnaround, with SOC 1/2/3 and HIPAA coverage.
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.
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.
Prescient Security is an option for SaaS already on Vanta — Vanta partner, Slack-based same-day audit communication, no on-site visits, and SOC 2 + ISO 42001 available together for AI-first SaaS.
Choose a SaaS auditor by testing three things before price: whether the firm understands your tenant-isolation model, whether it will scope Availability against contractual SLAs, and whether its evidence workflow fits your CI/CD and GRC stack. Then compare named engagement staff, observation-period timing, renewal effort, and the exact deliverables in writing.
A B2B SaaS company scaling enterprise sales should work backward from procurement deadlines and likely framework fan-out. Use a fast Type 1 only when the buyer accepts it, start Type 2 evidence in parallel, and shortlist firms that can coordinate SOC 2 with ISO 27001, ISO 42001, HIPAA, or PCI without duplicating evidence.
A bundled provider can simplify contracting, evidence collection, and platform support, while an independent firm can offer more separation and flexibility across GRC tools. Neither model is automatically better. Ask who employs the signing CPA, how independence is protected, what happens if you change platforms, and which work is preparation versus attestation.
The proposal should explain how recurring evidence will be reused, which samples must be refreshed, how control changes are handled, and whether renewal pricing assumes a stable scope. A credible SaaS auditor can describe the year-two workflow before fieldwork begins, including GRC integrations, request ownership, expected engineering time, and the treatment of new subprocessors.

Independent directory. Not owned by any audit firm or compliance platform; we take no cut of audit fees and charge nothing per lead. How we choose →
All firms have SaaS listed as a core industry vertical with documented experience auditing multi-tenant and cloud-native products. Sponsored firms are paid placements and listed first; the rest follow by verification and Type 2 entry price. Pricing is in USD and timelines are in weeks.
Type 1 and Type 2 figures reflect a mix of firm-confirmed numbers, public sources, and our own estimates, refreshed periodically. Actual cost depends on company size, scope, and Trust Service Criteria.
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. Companies pursuing multiple frameworks who want shared evidence across SOC 2 + ISO 27001 + HITRUST + PCI in a single audit cycle. Mid-market SaaS, fintech, and healthtech seeking 25-50% savings vs. traditional audit firms with fixed pricing.
Differentiator · Bundles a proprietary GRC platform with an in-house CPA firm, PCI QSAC and ASV, and HITRUST Authorized External Assessor under one roof. Same auditor from Day 1 through report issuance, no handoff between readiness vendor and audit firm. First Pass and Smart Sort AI pre-screen evidence before audit, cutting manual overhead up to 80% and completing audits up to 62% faster. 30+ frameworks on a single shared evidence set, plus a standalone audit module that works alongside Vanta, Drata, Secureframe, Hyperproof, Archer, and OneTrust. Active healthcare practice (Array Behavioral Care, Alaffia Health, HealthSnap) covering HITRUST + SOC 2 coordinated audits in PHI-sensitive environments.
Best for · Startups and growing SaaS, healthcare, fintech, and AI companies (1–100 employees) needing a first-time SOC 2 (Type 1 or Type 2) or HIPAA audit done economically and fast across AWS, Azure, or GCP, with in-house penetration testing and flexible payment terms. Every manager brings 5+ years at a Big Four or major national firm, so the work stays high-quality at boutique pricing
Differentiator · Economical, efficient SOC 2 without cutting quality: every audit manager brings at least five years at a Big Four or major national accounting firm (EY, Grant Thornton, and other large firms), so buyers get enterprise-grade rigor at startup pricing. A boutique CPA firm covering SOC 1, SOC 2, SOC 3, and HIPAA plus in-house penetration testing, running hundreds of audits a year with a ~30-person team. Co-founded by President & CPA Lance Samona and CTO Patrick Sesi, a Drata Advanced Alliance Member rated 5.0 across 15 reviews, known for the fastest turnaround in the industry, 24/7 support, and flexible payment terms
Best for · B2B SaaS companies (Series A through growth stage) using Drata, Vanta, or Secureframe that want a fast remote audit. AI/ML companies needing SOC 2 and ISO 42001 together. FinTech, healthtech, and security vendors. CSPs pursuing FedRAMP authorization. DoD contractors needing a C3PAO (authorized March 2026). Teams that prefer same-day audit communication over Slack.
Differentiator · A cybersecurity-first firm founded in 2018 by CREST-certified penetration testers rather than traditional accountants, run from a Nashville HQ with a distributed team of 200+ across the US, EMEA, and APAC and a same-day Slack/Teams response guarantee. SOC 2 engagements start around $10K with report delivery in 4-6 weeks once fieldwork begins. Holds FedRAMP 3PAO, CMMC C3PAO (March 2026), PCI QSA, HITRUST, and ANAB ISO accreditation for 27001/27701/42001, plus CREST and CSA STAR. Its Cacilian PTaaS platform and CAIT (Continuous AI Tester) add offensive security to the audit workflow. Operates under Prescient Security Management LLC as an AICPA alternative practice structure.
Best for · Small-to-mid-sized organizations ($5M-$100M revenue) without enterprise budgets. First-time SOC seekers wanting bundled pricing transparency ($30K Year 1 package: Gap + Type I + Type II, then $25K annual renewals). MSPs and IT service providers. Healthcare organizations needing HITRUST + HIPAA. Budget-conscious buyers valuing long-term partnership over transactional audits
Differentiator · Pricing transparency: documented $25K-$30K bundled packages with clear annual renewal pricing. Strong MSP community reputation with 4+ year client relationships. PCAOB-registered quality standards at accessible mid-market pricing. Boutique personalization at scale (130 employees serving 2,000+ clients = ~15 clients per employee). 18+ years experience (founded 2005) with $42M revenue demonstrates financial stability without PE pressure
Best for · Early-stage to mid-market SaaS, startups, and financial services companies needing SOC 1, SOC 2, or SOC 3 reports with hands-on partner involvement
Differentiator · Both partners are KPMG-trained IT practitioners rather than traditional financial-audit backgrounds: Jordan Novak (Managing Partner, CPA/CISSP/CISA/CRISC/CISM/CITP) brings Big Four IT audit plus in-house SOC ownership experience, and Tasya Novak (IT Audit Director, CISA) brings 13+ years of KPMG IT audit. Together they have 30+ years of combined IT audit experience across government, private, and public companies. Every engagement is partner-led from planning through delivery — no junior handoffs, direct communication, and purpose-built engagement tooling for onboarding and evidence gathering. Readiness assessment work is typically included alongside a Type 1 engagement, and the firm works with any of the major GRC compliance platforms. Sage states that it provides independent IT audit and assurance services as a licensed CPA firm, with IT consulting and advisory delivered to non-attest clients only, separate from any external audit or assurance engagement.
Best for · Mid-market to enterprise companies that need multiple compliance frameworks (SOC 2 + ISO 27001 + HITRUST + FedRAMP + PCI) under one roof. CSPs pursuing FedRAMP authorization. Companies that want a top-three FedRAMP 3PAO and #1 SOC 2 issuer on the cover of the report.
Differentiator · #1 issuer of SOC 2 reports in the world with 5,700+ clients and 31,000+ audits completed. Top-three FedRAMP 3PAO; CMMC C3PAO authorized. A-SCEND platform was the first audit-management platform from a top-3 3PAO to achieve FedRAMP 20x Low authorization (Sept 2025), now augmented with EvidenceIQ AI evidence scoring and Cross-Service framework reuse. Acquired by Hg in July 2025 at a $1B+ valuation, accelerating European expansion and AI investment. CEO Scott Price (founder, 2009); Steve Simmons elevated to President in January 2026.
Best for · Companies that want a long-term audit relationship over a transactional, checkbox engagement — and need a firm that can start immediately and cover SOC 2 alongside ISO 27001, ISO 42001, NIST, or HITRUST without bringing in a second vendor.
Differentiator · Independent, employee-owned CPA firm headquartered in Cincinnati (founded 1965, 225 staff) with roughly 20 people working exclusively on SOC reports. Readiness, audit, and issuance are handled entirely in-house with no outsourcing, by a team distributed across six time zones that serves two-person startups through large multinationals. SOC engagements are priced as a fixed fee rather than billed hourly, so the number is known before fieldwork begins, and the firm holds strong AICPA Peer Review standing. Multi-framework coverage (SOC 2, ISO 27001, ISO 42001, NIST, HITRUST, AI systems compliance) consolidates parallel attestations into one report, with a quality-and-relationship orientation rather than checkbox auditing. Notably fast: able to start engagements immediately, where most peers have multi-month lead times.
Best for · First-time SOC 2 buyers. Pre-Series A through Series B SaaS startups already running Drata, Vanta, Secureframe, or Rippling who want a fixed-fee, 4-to-6-week audit from an accredited CPA firm that also issues ISO 27001 certifications, HIPAA assessments, and PCI DSS reports under one roof. Founders who prioritize speed and price transparency over a brand-name auditor.
Differentiator · Boutique CPA firm with deep startup focus. Quoted 4-6 week turnaround on SOC 2 reports (top quartile for the market), fixed-fee engagements, flexible payment terms. IAS-accredited ISO 27001 certification body (MSCB-314, updated for ISO/IEC 27006-1:2024 in April 2026). Issues real ISO certificates rather than just attestations. Multi-framework one-stop shop: SOC 1/2/3, ISO 27001/27017/27018/27701, HIPAA, PCI DSS, GDPR, NIST, BSI C5. One of the launch-cohort independent audit firms partnered with Rippling Automated Compliance (announced April 2026). Drata Alliance Member with Code of Ethics Pledge; uses Drata internally to run audits even when clients aren't on it. Distributed/global remote team across multiple time zones, English + Spanish.

Joined the Axiom GRC family (alongside IS Partners and IMSM) in 2026, continuing to operate independently.

Companies combining SOC 2 + ISO 27001 (or SOC 2 + ISO 42001 for AI governance) in a single engagement. APAC-connected companies needing Essential 8, CDR, or GS 007 alongside US compliance.

Best for · Companies of any size, from early-stage startups to public companies and across every industry, that want an experienced firm which deeply understands security, technology, AI, and the SOC 2 framework. Fit here is less about size than approach: Fine Assurance tailors controls to each client's actual risk posture and is the right call for teams that want a precise, meaningful audit rather than the bare minimum.

SOC 2 lets you choose which Trust Service Criteria to include. Security is mandatory. Most B2B SaaS starts with Security and Availability; the right additions depend on product behavior and customer contracts.
| Factor | 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 for sensitive business data |
| Processing Integrity | Accurate, complete, 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 |
Five 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.
If you have committed to uptime in a customer MSA, enterprise security reviewers look for Availability coverage. Most first-time audits scope only Security, which may work for a first deal but not for SaaS with contractual uptime.
SaaS-experienced auditors evaluate pull-request approvals, deployment gates, and feature flags without asking you to document every release manually. Branch protection, code reviews, and deployment approval gates usually satisfy controls without slowing delivery.
Your scope includes how you evaluate, monitor, and contract with every vendor that touches customer data. SaaS-specialised firms bring vendor-tiering templates and know which subprocessors require SOC 2 reports versus basic security assessments.
After the first Type 2, SaaS-experienced auditors can reduce renewal effort by 50–70% through automated evidence collection from GRC platforms, CI/CD logs, and cloud monitoring. Ask how the firm will streamline year two before signing.
Four lines: auditor fees, GRC platform, security tooling, and 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.

Five questions specific to SaaS architecture, TSC selection, and ongoing compliance, separate from the general first-audit questions on the startups page.
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 and timelines shown reflect a mix of firm-confirmed figures, public sources, and our own estimates, refreshed periodically. Actual costs and timelines vary based on company size, complexity, and scope.
