Hyperproof · TrustCloud (TryComp) · Scytale · Sprinto · Thoropass · Drata · Vanta · Delve · Scrut · Secureframe — on the one ISO 27001 axis nobody publishes but every CISO asks about: did the company pass on the first attempt. Operator-honest. Per-vendor confidence. No vendor sponsorship.

"First-attempt pass rate" is the axis nobody publishes a number on but every CISO asks about during procurement. ISO 27001 Stage 2 audits don't grade pass/fail in the binary way customers think — accredited certification bodies issue findings (minor non-conformities, major non-conformities, observations); a "pass" usually means "no major NCs, minor NCs closed in the corrective-action window." Across the 11 named vendors, Thoropass structurally biases toward high first-attempt rates because its in-house audit firm rehearses the audit before the certification body sees it. Hyperproof reviewers tend to report strong first-attempt outcomes because the platform is GRC-deep — the customers who pick Hyperproof are usually mature compliance teams who would pass anyway. Drata and Vanta have the largest customer cohorts on this list, and reviewer text on first-attempt outcomes is consistently positive when the customer follows the platform's evidence-collection guidance (variance is customer-driven not platform-driven). Secureframe and Sprinto reviewers report similar outcomes — strong first-attempt rates when onboarding rigor is followed. Scrut and Scytale have growing customer bases and reviewer text is positive but lower in volume. Delve is too new (2024+) for meaningful pass-rate evidence — vendor markets aggressive claims; verify with reference customers who have certificates in hand. TrustCloud (formerly TryComp / TrustComplianced) similarly has thin reviewer evidence on this axis at time of writing.
This ranking is operator-honest, not Gartner-published. Gartner Peer Insights itself does not publish a single "ISO 27001 first-attempt pass rate" leaderboard — and no vendor publishes a real number either. This is SideGuy's synthesis of public review text on that sub-axis as of 2026-05-13. Customer-side execution drives most of the variance; an immature compliance team will fail first-attempt regardless of vendor.

Note on outcomes: No vendor publishes a real first-attempt pass-rate percentage. Any specific number you see in vendor marketing should be treated as marketing not measurement. The table above uses qualitative reviewer-text reads — "strong / consistent / predictable / positive / sparse" — instead of fabricating numbers. 11th-vendor note: the original Gartner search query named 11 brand tokens — "trycomp" and "trustcompliance" resolve to the same company (TrustCloud, formerly TrustComplianced / TryComp.ai); functional list = 10 distinct vendors.

Thoropass's structural advantage on first-attempt outcomes is the in-house audit firm that effectively rehearses the audit before the certification body sees it. Findings get caught and corrected pre-Stage-2 in a way external-auditor models can't replicate as cleanly. Tradeoff: less independence-optics; some procurement teams require vendor-auditor separation.
Hyperproof's reviewer-noted strong first-attempt outcomes are partially selection effect — the platform is GRC-deep and the customers who pick it are usually mature compliance teams who would pass anyway. The platform itself supports thorough Annex A coverage and pre-audit gap analysis. If your team is already GRC-mature, Hyperproof minimizes platform-side risk; if you're brand-new to ISO 27001, you may want a vendor with more onboarding rails.
Drata reviewer text on Stage 2 outcomes is consistently positive when customers follow the platform's evidence-collection cadence. The smooth platform-to-auditor handoff compresses the back-and-forth that often surfaces minor non-conformities late in the audit. Large customer cohort means lots of public review evidence — read the actual review text for outcomes specific to your industry.
Vanta has the largest reviewer cohort for ISO 27001 outcomes on Gartner Peer Insights. First-attempt outcomes are positive when customers follow Vanta's playbook; variance is customer-driven not platform-driven. With 100+ auditor partners, the certification-body experience itself varies — ask Vanta which audit firm they're going to put you with and check that firm's reputation separately.
Secureframe's onboarding rigor produces predictable Stage 2 outcomes in reviewer text — the platform front-loads the gap analysis and policy-approval work that often surfaces as findings during the audit. If your buyer wants timeline + outcome confidence over absolute speed, Secureframe is the safer cohort pick on this axis.
Sprinto's reviewer text on ISO 27001 outcomes is strong for its India/APAC mid-market ICP, with consistent first-attempt success when the platform's onboarding cadence is followed. US enterprise customer reviewer count is lower; ask for US reference customers if that's your segment. Aggressive onboarding cadence reduces customer-side execution variance.
Scrut's reviewer text on ISO 27001 outcomes is positive but lower in volume than the larger incumbents. The platform's UX is cleaner for first-time ISO 27001 buyers, and Annex A coverage is full. Worth a direct conversation if you're new to ISO 27001 and want a leaner platform with auditor handoff included.
Scytale's reviewer text on ISO 27001 first-attempt outcomes is positive within its EMEA/Israel customer base, with lower public review volume than US-headquartered competitors. The auditor-partner network is EMEA-tilted, which is an advantage if your certification body is also EMEA-based. Annex A coverage is full.
Delve markets aggressive ISO 27001 outcome claims tied to its AI-positioning. Gartner Peer Insights review evidence on actual realized first-attempt outcomes is sparse — vendor is the youngest on this list (2024+). Treat marketing claims as marketing claims; ask for reference customers with ISO 27001 certificates in hand and dated Stage 2 reports before betting on outcomes.
TrustCloud frames ISO 27001 first-attempt outcomes inside its broader TrustOps platform pitch. Public reviewer evidence on this axis specifically is sparse on Gartner Peer Insights at time of writing — the platform is real and operational; the first-attempt-outcomes read is just under-witnessed. Verify directly with the vendor.
Lived-data observations from SideGuy compliance procurement work and the prior ISO 27001 cluster on these vendors. The scars vendors won't ship.
ISO 27001 Stage 2 audits don't grade pass/fail like a high school test. Accredited certification bodies issue findings in three buckets: major non-conformities (block certification until corrected), minor non-conformities (close in a corrective-action window, usually 30-90 days, then certify), and observations (advisory only). Most "first-attempt passes" actually mean "no major NCs, minor NCs closed in window." Vendor marketing collapses all of this into a single "pass rate" — which is why no vendor publishes the real number.
The single biggest first-attempt risk SideGuy has seen isn't control implementation — it's the scope statement. Customers under-scope to "look smaller and pass faster," then a Stage 2 finding catches an out-of-scope system that should have been in scope. Conversely, over-scoping creates unnecessary work and findings on systems that didn't need to be in. Spend more time on scope at Stage 1 than on any other deliverable; vendor choice matters less than scope discipline.
Thoropass's in-house audit firm structurally compresses first-attempt risk because findings get rehearsed pre-certification. But some procurement teams (especially regulated industries, financial-services-adjacent) explicitly require vendor-auditor separation as a governance control. Ask the buyer's compliance/legal lead before assuming Thoropass's structural advantage is a clean win.
If a vendor cites a specific first-attempt pass-rate percentage, ask three things: (1) sample size, (2) how "pass" is defined (no major NCs? all NCs closed?), (3) whether the percentage is across all customers or only a self-selected reference cohort. If they can't answer cleanly, the number is marketing. The honest answer most vendors should give is "our customers consistently certify on first attempt when they follow our playbook" — qualitative not quantitative.
Different accredited certification bodies (BSI, DNV, Schellman, A-LIGN, etc.) interpret Annex A controls with slightly different rigor. The same control implementation can produce a finding from one CB and an observation from another. When evaluating a vendor's first-attempt outcomes, also ask which certification bodies their customers most commonly use — and check that CB's reputation separately. Vendor + auditor network are joint inputs, not separable.
Operator-honest doctrine: every claim on this page has a confidence level. Use this section to calibrate how much weight to put on each vendor's ranking. KNOW = verifiable from public Gartner Peer Insights review pages or vendor public case-study pages. BELIEVE = consistent across multiple SideGuy data points but not directly cited. UNCERTAIN = sparse evidence; verify yourself.
KNOW: in-house audit firm is publicly stated; structural advantage on first-attempt outcomes is real. BELIEVE: reviewer-noted strong outcomes are causally driven by the in-house rehearsal model. UNCERTAIN: exact first-attempt percentage (vendor doesn't publish a real number — neither does anyone else).
KNOW: GRC-deep platform; reviewer text on Stage 2 outcomes is positive. BELIEVE: outcomes are partially selection effect — mature customer cohort skews positive regardless of platform. UNCERTAIN: how Hyperproof would perform with an immature compliance team that doesn't fit the typical ICP.
KNOW: large customer cohort with consistent positive reviewer text on first-attempt outcomes. BELIEVE: the smooth platform-to-auditor handoff compresses minor-NC surfacing late in the audit. UNCERTAIN: outcome variance by certification body — different CBs interpret findings differently.
