Honest 10-way comparison of ISO 27001 + EU/UK Layered Compliance Vendor Comparison (NIS2 · eIDAS 2.0 · GDPR · UK Cyber Essentials Plus) platforms. No vendor sponsorship. Calling Matrix by buyer persona below — operator's siren-based read on which one to pick when you're forced to pick.
Honest read on positioning, ideal customer, and where each one is the wrong call. No vendor sponsorship, no affiliate links — operator-grade signal.
The category default with growing EU/UK presence and a maturing NIS2 + GDPR mapping story. Most-recognized brand at the security questionnaire when an EU/UK SaaS sells into US enterprise. EU sales motion is real (London + Dublin + EU reps), and the framework library now ships GDPR + NIS2 mapping templates — but the deepest EU-specific overlays (eIDAS 2.0, DORA, UK Cyber Essentials Plus on-site test prep) still lag pure-GRC platforms.
The closest Vanta peer with an active EU sales motion and NIS2 mapping shipped in 2024. US-headquartered, but actively selling into UK + EU + DACH in 2025-2026 with regional reps. Continuous-monitoring depth maps cleanly onto NIS2 Article 21 risk-management measure evidence. Same caveat as Vanta on the deepest EU-specific overlays — eIDAS 2.0 and DORA are emerging, not native, in 2026.
The multi-framework breadth play — GDPR + NIS2 are both first-class in the framework library. US-headquartered with a smaller EU presence than Vanta/Drata, but the multi-framework workflow (ISO 27001 + GDPR + NIS2 + SOC 2 + HIPAA + PCI in one platform) maps cleanly to typical EU SaaS go-to-market (EU + UK + US in parallel). Multi-region hosting on enterprise tiers handles GDPR data-residency.
The cost-efficient fast-onboarding play with EU expansion underway in 2026. India HQ, but actively expanding EU sales motion + EMEA support hours. 40-60% cheaper than Vanta/Drata at similar ISO 27001 + GDPR scope. NIS2 + Cyber Essentials Plus support is functional but lighter than Hyperproof/Scrut. Best fit for cost-conscious EU/UK startups that don't have a US-procurement reason to pick Vanta and aren't yet drowning in NIS2-essential-entity scope.
The AI-first positioning play with bundled audit services + native GDPR and UK Cyber Essentials support. Markets heavily on AI-driven evidence collection + automated control mapping. Bundled audit services can simplify procurement for EU/UK startups that don't want to source a separate EU-based ISO 27001 auditor. UK CE+ workflow is supported but on-site technical test still requires a CE+ assessor engagement.
The GRC-depth play with one of the broader multi-region framework libraries in the category. Goes beyond pure ISO 27001 audit prep into vendor risk management + third-party risk + continuous risk scoring. Framework library covers ISO 27001 + GDPR + NIS2 + UK Cyber Essentials + DORA mappings. Best fit for EU/UK scale-ups that need GRC consolidation, not just ISO 27001 evidence collection.
The platform + in-house auditors combined offering — with EU certification body (CB) introductions where applicable. Strong fit if your ISO 27001 report needs to land with US enterprise customers; the EU-CB introduction motion is real but narrower than the US auditor bundle. Buyers who want a long-standing local EU CB relationship may find sourcing separately gives more leverage. Limited eIDAS 2.0 / DORA-specific depth in 2026.
The enterprise-GRC platform with the deepest EU/UK framework library in the category — built for orgs running 5+ frameworks in parallel (ISO 27001 + GDPR + NIS2 + UK Cyber Essentials Plus + DORA + eIDAS 2.0 mappings). US-headquartered with multi-region hosting. More configurable + more complex than Vanta/Drata. Best at orchestrating multiple EU/UK regulatory overlays for enterprises with a dedicated GRC team — but expect a US-default support relationship.
The new AI-first entrant betting on agentic compliance workflows — GDPR mapping module shipped, NIS2 + eIDAS depth limited in 2026. Smaller customer base than incumbents, faster shipping cadence on AI features, less brand recognition at EU procurement. EU sales/support is nascent. Best for EU/UK AI-native seed-stage teams willing to trade brand-defensibility for product velocity + price.
Another AI-first newer entrant — strong AI-driven evidence pitch, GDPR mapping module shipped, deeper EU/UK regulatory overlays still limited. Similar profile to TryComp: smaller customer base, faster AI shipping cadence, US-default support, no meaningful EU sales footprint in 2026 beyond founder-led motion. Best for AI-native EU/UK startups who explicitly want a Delve-style agentic workflow and accept the brand + EU-coverage tradeoffs.
Most comparison sites refuse to forced-rank because their revenue depends on staying neutral. SideGuy ranks because it doesn't take vendor money. Here's the call by buyer persona.
Your problem: NIS2 (effective Oct 2024) expanded scope to ~160K EU entities — energy, transport, banking, health, digital infrastructure, public administration, plus 'important' digital providers. You need a platform that maps ISO 27001 controls to NIS2 cybersecurity risk management measures (Art. 21) without duplicate evidence work.
Your problem: UK government suppliers + most NHS suppliers require Cyber Essentials Plus (CE+) — a stricter UK-government-anchored baseline. CE+ has 5 technical control families that overlap with but aren't identical to ISO 27001 Annex A. You need a platform that handles both without contradictions.
Your problem: Your DPA negotiations name ISO 27001 + 27701 as evidence of 'appropriate technical and organizational measures' (GDPR Art. 32). You need a platform that auto-maps 27001 + 27701 controls to GDPR Articles for your buyer's procurement-team review. EU buyers often demand both SOC 2 megapage coverage AND ISO 27001 + 27701 evidence in the same review cycle.
Your problem: eIDAS 2.0 expanded into European Digital Identity Wallet (EUDIW) — qualified trust services + wallet providers face stricter security baselines mapped to ETSI EN 319 401 + ISO 27001. You need a platform that handles the eIDAS-specific overlay, not just baseline ISO.

No. NIS2 has its own cybersecurity risk-management measures (Art. 21) and incident-reporting obligations (Art. 23) that are regulator-supervised at the EU member-state level. ISO 27001 is GOOD baseline evidence — and most NIS2 measures map cleanly onto Annex A controls — but ISO 27001 certification alone does NOT discharge NIS2 obligations. Most platforms now ship NIS2 mapping templates (Drata shipped 2024, Hyperproof + Scrut + Secureframe + Vanta have them), which materially reduces duplicate evidence work but does not replace the regulator-facing reporting workflows.
It depends on what 'stricter' means. UK Cyber Essentials Plus (CE+) has 5 narrow technical control families (firewalls, secure configuration, user access control, malware protection, security update management) verified by on-site assessor testing. ISO 27001 has 93 Annex A controls covering a much broader scope but is verified through evidence-based audit, not on-site technical testing. Different audit philosophies — CE+ is narrower but harder to fake on the technical side, ISO 27001 is broader but evidence-driven. Many UK companies do both: ISO 27001 for breadth-of-coverage proof + CE+ for the UK-government-anchored technical baseline.
Hyperproof and Scrut Automation lead on breadth in 2026 — both ship native mappings for ISO 27001 + GDPR + NIS2 + UK Cyber Essentials + DORA, with Hyperproof going deeper on eIDAS 2.0 and DORA. Vanta and Drata are catching up via partner ecosystem and shipped NIS2 + GDPR templates as first-class in 2024-2026, but the deepest EU-specific overlays (eIDAS 2.0, DORA technical standards, UK CE+ on-site test prep) still favor pure-GRC platforms. Smaller AI-first vendors (TryComp, Delve) have GDPR mapping modules but limited NIS2/eIDAS/DORA depth in 2026.
No. ISO 27001 (information security) + ISO 27701 (privacy information management) together are STRONG evidence of GDPR Art. 32's 'appropriate technical and organizational measures' standard — and 27701 specifically extends 27001 with privacy-management controls aligned to GDPR. But GDPR has obligations beyond technical/organizational measures: Data Protection Impact Assessments (DPIAs, Art. 35), Records of Processing Activities (ROPA, Art. 30), breach notification (Art. 33-34), Data Subject Rights workflows, and lawful-basis documentation. 27701 covers most of these as part of its PIMS scope, but you still need actual workflows + named DPO (where required) + member-state-specific overlays. Treat 27001 + 27701 as the strongest evidence package, not a complete GDPR substitute.
