Best SOC 2 Compliance Software: 8 Platforms Ranked

ISO 27001 vs SOC 2 usually gets answered as "it depends on your customers" — SOC 2 for the US, ISO 27001 for everyone else — and that's true as far as it goes. But the question engineering leaders actually need answered is narrower: which specific access controls will an auditor test, and can one control set satisfy both? The short version: roughly 70–80% of the access-control work overlaps, but each framework wants that work documented differently. If you're mapping this out before an audit, Gart Solutions' compliance audit team can tell you in one session exactly which gaps are framework-specific and which are shared. Every engineering leader who has been asked "are you SOC 2 or ISO 27001 compliant?" by a prospect's security team knows the question is really a proxy for something else: can we trust who has access to our data, and can you prove it? Both frameworks answer that question, but they test it through different lenses — one through a period-of-time attestation, the other through a certified management system. Understanding exactly where they overlap and where they diverge is what keeps a compliance program from turning into two parallel, redundant projects. ISO 27001 vs SOC 2 at a Glance Before the detail, here's the comparison in one table — the version most people searching "ISO 27001 vs SOC 2" actually want first: DimensionISO 27001SOC 2What you getA certificate confirming your ISMS conforms to ISO/IEC 27001:2022An auditor's attestation report on your controls (Type I or Type II)Issued byAccredited certification body (e.g., BSI, LRQA, DEKRA)Licensed CPA firm, per AICPA standardsGeographyRecognized globally; strongest in EU, UK, APAC, Middle EastDe facto standard for U.S. and North American buyersStructure93 Annex A controls across 4 themes, scoped via a Statement of Applicability5 Trust Services Categories; only Security (the Common Criteria) is mandatoryAssessment stylePoint-in-time conformance audit against the management systemType I = point-in-time design check; Type II = 6–12 months of operating evidenceValidity3 years, with annual surveillance audits in betweenTypically re-issued every 12 monthsReport visibilityPublic-facing certificate (a logo you can display)Confidential report shared under NDA with customers/prospectsISO 27001 vs SOC 2 What Is ISO 27001? ISO/IEC 27001 is an international standard, maintained jointly by ISO and the IEC, that specifies the requirements for building, operating, and continually improving an Information Security Management System — the documented, risk-based process an organization uses to manage information security on an ongoing basis, not a one-time checklist. Certification confirms that your ISMS conforms to the standard: you've identified your information security risks, selected and implemented controls to address them (drawn from Annex A's 93 controls, organized into Organizational, People, Physical, and Technological themes), documented why each applicable control exists in a Statement of Applicability, and committed to reviewing the whole system on a fixed cadence. A first-time certification runs through a two-stage external audit — Stage 1 checks your documentation is complete, Stage 2 tests whether the ISMS is actually operating as designed — after which the certificate is valid for three years, with annual surveillance audits in between to confirm the system is still functioning. Unlike SOC 2, ISO 27001 doesn't lock you into one country's audit standard: the same certification is recognized by procurement teams and regulators across the EU, UK, Middle East, and Asia-Pacific, which is why it tends to matter more the further your customer base sits from North America. What Is SOC 2? SOC 2 (System and Organization Controls 2) is an attestation framework defined by the AICPA's Trust Services Criteria and delivered by a licensed CPA firm, not a certification body. Rather than certifying a management system, a SOC 2 report is the auditor's own opinion — did the organization's controls exist, and did they operate effectively, against whichever of the five Trust Services Categories the company chose to scope in: Security (mandatory for every report, also called the "Common Criteria"), Availability, Processing Integrity, Confidentiality, and Privacy. There are two report types, and mixing them up is the single most common SOC 2 misunderstanding: a Type I report is a snapshot — it confirms controls are designed appropriately as of one date — while a Type II report is what most enterprise buyers actually require, confirming those same controls operated effectively across an observation window, typically six to twelve months. Because SOC 2 tests operating effectiveness over time rather than certifying a management system, the report itself carries no multi-year validity — it's reissued roughly annually, and a lapsed report is treated by most procurement teams as equivalent to no report at all. Our step-by-step SOC 2 preparation guide walks through the full audit-readiness process if you're just starting that path, and our breakdown of why SOC 2 audits fail covers the evidence gaps that most often derail a Type II window. ISO 27001 vs. SOC 2: What Each One Actually Certifies The single most useful thing to internalize before comparing individual controls: SOC 2 is an attestation, and ISO 27001 is a certification. A SOC 2 report is an independent auditor's opinion, issued after they test whether your controls operated effectively over a defined period (typically 6–12 months for a Type II report). An ISO 27001 certificate, by contrast, confirms that your Information Security Management System (ISMS) — the documented, risk-based process for managing security on an ongoing basis — conforms to the official ISO/IEC 27001:2022 standard, re-verified through annual surveillance audits and a full recertification every three years. That distinction cascades into everything else. SOC 2 asks, "did your access controls actually work, consistently, over the last year?" ISO 27001 asks, "do you have a management system that identifies access-related risks, treats them, and reviews the treatment on a schedule?" A company can pass one and fail the other for reasons that have nothing to do with the strength of its actual access controls — usually because the documentation trail doesn't tie back to a Statement of Applicability or risk treatment plan the way ISO auditors expect. If you're earlier in the decision and haven't picked a framework yet, our dedicated guides go deeper on each: preparing for a SOC 2 audit and why ISO 27001 matters for growing companies. This article assumes you already know you need one or both, and want the access-control specifics. Access Control Requirements Side by Side SOC 2's access-control requirements live almost entirely in CC6 (Logical and Physical Access Controls), one of the nine Common Criteria every SOC 2 report must address regardless of which Trust Services Categories you scope in. ISO 27001's equivalent requirements are spread across Annex A.5 (Organizational Controls) and Annex A.8 (Technological Controls), per the AICPA's Trust Services Criteria and the 2022 revision of the ISO standard, respectively. Here's how the two map onto each other in practice: RequirementSOC 2 (CC6)ISO 27001:2022 (Annex A)Governing clauseCC6.1–CC6.8, Logical and Physical Access ControlsA.5.15–A.5.18 (access control, identity management, access rights), A.8.2–A.8.5 (privileged access, restriction, authentication)Multi-factor authenticationExpected wherever risk warrants it; tested as an operating control over the report periodRequired under A.8.5 (secure authentication) as part of the ISMS-documented policyLeast privilege / RBACCC6.3 — access restricted based on job role and functionA.5.15, A.5.18 — access rights granted per documented access control policyAccess reviewsTested as operating effectively across the audit period (evidence of periodic review required)Required on a defined schedule, tied back to the risk treatment plan and management reviewJoiner-Mover-Leaver processCC6.2 — provisioning and deprovisioning of credentialsA.5.16, A.5.18 — identity lifecycle management under the ISMSPrivileged access managementCovered within CC6.1/CC6.3 as elevated-risk accessA.8.2 — dedicated control for privileged access rightsEvidence styleOperating-effectiveness evidence sampled across a 6–12 month periodPoint-in-time conformance to the ISMS, verified via annual surveillance auditsAccess Control Requirements Side by Side What SOC 2 Actually Requires for Access Controls SOC 2's CC6 criteria are deliberately outcome-focused rather than prescriptive — the standard doesn't mandate a specific tool or exact review cadence, but auditors will expect to see evidence that access is provisioned based on role, reviewed periodically, and revoked promptly when someone changes roles or leaves. In practice, that means an auditor sampling your environment over the report period wants to see: registered and authorized user accounts before credentials are issued (CC6.2), access removed within a reasonable window of offboarding, and network segmentation or encryption protecting data in transit and at rest for anything access-controlled (CC6.6–CC6.7). The practical trap teams fall into is treating CC6 as a one-time configuration exercise rather than an operating control. Because SOC 2 Type II tests effectiveness over months, not a single snapshot, an access review policy that exists on paper but wasn't actually run in month four of the audit period will fail the test even if the policy document itself looks perfect. What ISO 27001 Actually Requires for Access Controls ISO 27001's access control requirements ask for the same underlying discipline — least privilege, MFA, timely deprovisioning — but wrap it in a formal management system. A.5.15 requires a documented access control policy; A.5.16 and A.5.18 require identity and access-rights processes that tie back to defined roles; A.8.2 singles out privileged access as needing dedicated controls; and A.8.5 requires secure authentication mechanisms appropriate to the risk. The distinguishing requirement, per the official ISO/IEC 27001:2022 standard, is that every one of these controls must trace back to your organization's risk assessment, appear (or be justifiably excluded) in your Statement of Applicability, and get revisited during scheduled management reviews. This is where the "ISO 27001 is more work" reputation comes from — not because the individual technical controls are harder to implement, but because the standard requires you to show why each control exists in relation to a specific identified risk, not just that the control is switched on. NIST's own access control catalog, SP 800-53 Revision 5, documents a similar principle in its AC control family: access controls are only as strong as the governance process that assigns and reviews them, regardless of which standard is doing the certifying. The Access Controls You Actually Need, Regardless of Framework Strip away the audit terminology and both frameworks are testing the same underlying security hygiene. If you build these seven controls properly, you've satisfied roughly 70–80% of the access-control requirements for either standard — the remaining work is documentation and evidence, not new technical controls: Multi-factor authentication everywhere it matters — every admin console, VPN, production system, and identity provider login, not just customer-facing accounts. Role-based access control built on least privilege — permissions assigned to roles, not individuals, with no standing access to production beyond what a role genuinely requires. Our deep-dive on RBAC in CI/CD pipelines covers this at the deployment-pipeline layer specifically. A documented Joiner-Mover-Leaver process — access granted on day one, adjusted automatically on role changes, and revoked same-day on offboarding, with an audit trail proving it happened. Scheduled access reviews — quarterly at minimum for privileged accounts, with sign-off from the resource owner, not just IT. Privileged access management (PAM) — a separate, more tightly monitored tier for admin and root-level credentials, ideally with just-in-time elevation instead of standing privilege. Centralized access logging and monitoring — every authentication and authorization event captured somewhere an auditor (and your own incident responders) can actually query it. Encryption tied to access boundaries — data at rest and in transit protected in a way that reinforces, rather than substitutes for, the access control layer. None of this is exotic — it's the same discipline good DevSecOps practice already asks for. Our guide to DevSecOps covers how to bake these controls into delivery pipelines rather than bolting them on before an audit. Building One Control Set for Both Frameworks Because the technical overlap is so high, the efficient path for most companies pursuing both certifications isn't building two access control programs — it's building one and mapping it to two sets of evidence requirements. A single access review process can satisfy SOC 2's operating-effectiveness test and ISO 27001's scheduled-review requirement, provided you keep the documentation trail both auditors need: Write one access control policy, but explicitly reference both the SOC 2 Trust Services Criteria and your ISO 27001 Statement of Applicability inside it, so either auditor can trace the same document to their standard. Automate provisioning and deprovisioning through your identity provider rather than ticket-based manual processes — this is the single highest-leverage control for passing both CC6.2 and A.5.16 cleanly. Practices like policy as code let you enforce and evidence this automatically rather than after the fact. Run access reviews on a fixed quarterly cadence and retain the sign-off records — SOC 2 auditors will sample across the report period, ISO auditors will check the schedule was actually followed. Tie every control back to a documented risk, even the ones you're implementing "because SOC 2 asked for it" — this single habit is what makes the same control set defensible under ISO 27001's ISMS requirements without extra work later. Centralize evidence collection — screenshots, logs, and approval records stored once, tagged against both frameworks' control IDs, rather than gathered separately for each audit cycle. Companies expanding into the EU should also factor in NIS2, which leans on many of the same access-control fundamentals for organizations providing digital infrastructure or services in scope — another reason to build the control set once, well, rather than framework-by-framework. Cost Comparison: What Each Framework Actually Costs in 2026 Cost is the question most competing comparisons answer vaguely — actual pricing depends heavily on company size, scope, and how mature your controls already are going in. Based on typical first-year totals reported across accredited certification bodies and audit firms in 2026 (audit fees plus reasonable implementation/prep cost, before any GRC tooling subscription), here's a realistic range by company size: Company sizeISO 27001 (first-year, implementation + certification audit)SOC 2 Type II (first-year, prep + audit)Startup / SMB (<50 employees)$25,000 – $60,000$20,000 – $45,000Mid-market (50–250 employees)$45,000 – $100,000$35,000 – $75,000Enterprise (250+ employees)$80,000 – $200,000+$65,000 – $150,000+Cost Comparison: What Each Framework Actually Costs in 2026 Two cost dynamics are worth planning around rather than being surprised by. First, ISO 27001's first-year cost usually runs somewhat higher than SOC 2's at a comparable company size, mostly because building a complete ISMS and Statement of Applicability from scratch is more upfront documentation work than scoping and preparing for an attestation — but ISO's costs flatten out more in years two and three, since only lighter surveillance audits are due until the three-year recertification. Second, SOC 2 doesn't have that grace period: because a Type II report is refreshed roughly annually, its cost repeats at close to full weight every year, which narrows the multi-year cost gap between the two frameworks more than a first-year comparison alone suggests. Timeline: How Long Each Certification Actually Takes Framework / report typeTypical timelineSOC 2 Type I4–8 weeks prep, then a point-in-time audit — fastest path to a first reportSOC 2 Type II4–8 weeks prep + a 6–12 month observation window before the report is issuedISO 27001 (first certification)3–6 months to build the ISMS, then a two-stage audit — 6–12 months total is typical end to endISO 27001 (ongoing)Annual surveillance audits (lighter scope) + full recertification every 3 yearsTimeline: How Long Each Certification Actually Takes The practical read: if a deal is closing in the next quarter and the prospect needs proof of security controls fast, a SOC 2 Type I report is the quickest credible artifact you can produce. If the requirement is a multi-year commitment or an international contract, budgeting for ISO 27001's longer runway up front avoids a scramble later — sequencing is covered in more depth in our guide to why ISO 27001 matters for growing companies. Which Framework Should You Choose? The honest answer is "it depends who's asking" — use these four signals, in order, to make the call: Your customer base is mostly U.S.-based Start with SOC 2. It's the default expectation in American enterprise procurement, and Type I gives you a credible artifact within weeks. You sell into the EU, UK, or APAC Prioritize ISO 27001. It's the internationally portable certification those buyers recognize immediately, and it often satisfies procurement checklists SOC 2 alone won't clear. You're pre-revenue or very early-stage A SOC 2 Type I report is usually the fastest, cheapest way to unblock your first few enterprise deals without committing to a multi-year ISMS build. You're regulated, or in a data-sensitive industry Consider both from the start — healthcare, fintech, and public-sector-adjacent vendors are increasingly asked for ISO 27001 and SOC 2 as separate, non-substitutable requirements. What Changed for ISO 27001 and SOC 2 in 2026 Two dated facts matter for anyone comparing these frameworks right now, and neither shows up in most existing "ISO 27001 vs SOC 2" comparisons written before this year: The ISO 27001:2022 transition deadline has closed. Per the International Accreditation Forum's three-year transition rule, every organization holding an ISO 27001 certificate had until 31 October 2025 to move from the 2013 revision to ISO/IEC 27001:2022, confirmed by accredited certification bodies including LRQA. That means every currently valid ISO 27001 certificate in the market is on the 2022 revision — if a vendor shows you documentation still referencing the 2013 control set, either it has lapsed or it's out of date, which is worth checking directly in vendor due diligence. SOC 2 didn't get a new official version, but audits got heavier. The AICPA hasn't issued a full new revision of the Trust Services Criteria for 2026, but auditors are applying existing guidance more strictly — particularly around documenting how risk assessment informs control design, and scrutinizing subservice-organization and vendor dependencies more closely inside the report itself. The practical effect for anyone preparing a report this year: budget more time for vendor and subprocessor documentation than a first-time SOC 2 program would have needed a few years ago. Common Mistakes When Choosing Between ISO 27001 and SOC 2 Picking based on which one a competitor has. The right first framework follows your actual customer base and deal pipeline, not industry habit. Assuming one substitutes for the other. Enterprise security teams frequently ask for both, especially once a vendor sells across regions — neither framework is a universal replacement for the other in a buyer's eyes. Underestimating SOC 2 Type II's observation window. Teams that start evidence collection late in the window often discover gaps with no time left to remediate before the report is due. Treating ISO 27001 as a one-time project. The certificate lapses without annual surveillance audits and a full recertification every three years — it's a maintained system, not a one-off deliverable. Building two separate control programs. Given 60–80% overlap, running ISO 27001 and SOC 2 as unrelated projects duplicates most of the actual engineering work for no real benefit. Confusing the framework decision with the tooling decision. GRC platforms automate evidence collection for whichever framework you've already chosen — they don't choose the framework, your risk assessment and customer base do. Which Framework Should You Get First? If most of your customers and prospects are US-based, SOC 2 Type II is usually the faster path to closing enterprise deals — it's the report US security teams ask for by default, and it can typically be completed in a shorter timeline than a first-time ISO certification. If you're selling into the EU, UK, or other international markets, ISO 27001 tends to carry more weight, partly because it's a recognizable international certification rather than a US-specific attestation format, and partly because it dovetails with regional requirements like NIS2 for in-scope organizations. Many growth-stage companies that serve both markets end up pursuing both within 12–18 months of each other. The sequencing advice we give most often: build the access control program to ISO 27001's documentation standard from the start — Statement of Applicability, risk treatment plan, management review cadence — even if SOC 2 is your first audit. It's far less costly to over-document once than to retrofit ISO-grade documentation onto a SOC 2 program that was built to a lighter evidentiary bar. Our infrastructure audit process walks through exactly where most companies' current documentation falls short of that standard before either audit begins.
