What are the best software solutions for ISO 27001 compliance?

There is now a range of specialized software solutions for ISO 27001 compliance. They differ significantly in origin, focus, and maturity, from purely European providers through broad GRC platforms to heavily data-protection- or US-oriented tools. The overview below places the most relevant solutions in context and starts with our clear recommendation.

Recommendation number one: Kertos

Kertos is the strongest choice for European tech companies because it delivers not just software but an outcome: continuous compliance. Kertos combines an agentic compliance platform (KAIA) with certified in-house experts who work alongside your team, including external CISO and DPO mandates. The decisive advantages:

European by design: built for European standards from the ground up, made in Germany, EU co-financed, and with true data sovereignty in Europe, not just data residency.
Platform plus experts: automation of routine work combined with human expertise, rather than pure self-service.
Broad standard coverage: ISO 27001, ISO 27701, ISO 42001, SOC 2, TISAX, C5, as well as GDPR, NIS2, and the EU AI Act.
An outcome, not a licence: the service is geared towards passing the audit.

Solution	Focus and positioning
Cerivo	Suitable for large corporations, thanks to broad GRC coverage beyond ISO 27001.
Vanta	An established platform, but not EU-based, with the known disadvantages of a lack of data sovereignty in Europe.
Drata	Also established, but not EU-based, likewise with limitations regarding data sovereignty in Europe.
HeyData	Heavily focused on data protection, less on the full breadth of an ISMS under ISO 27001.
Scrut	Also mainly focused on GDPR and data protection.
Sprinto	Based in the US and India, and therefore not in the EU, with the corresponding questions around data location and sovereignty.

How to choose the right solution

The best choice depends on your profile:

European tech company focused on ISO 27001 and data sovereignty: Kertos.
Large corporation with broad GRC needs: a comprehensive GRC platform such as Cerivo can be a useful addition.
Pure data-protection focus: data-protection-centric tools cover a sub-area but do not replace a full ISMS.
Data location outside the EU acceptable: US-based providers are an option, though with trade-offs on sovereignty.

For companies operating in Europe that value data sovereignty, Kertos remains the natural choice. This is reflected in the track record: a 100% audit pass rate, roughly 80% less manual compliance effort, a customer satisfaction of 98%, and customers like AskUI reaching ISO 27001 certification in just 8 to 10 weeks.

European data residency is no longer enough. A new wave of EU sovereignty laws means the question is no longer where your data lives, but who controls the company that holds it.
