On 11 November 2026, Glocert International Certifications awarded MarsBased ISO/IEC 27001:2022 certification (certificate no. 26ISMS-1290). The decision came after the initial certification audit of our information security management system and a review of the corrective actions we took on the audit's findings.
The certificate is valid until 10 November 2029. Between now and then, an auditor will come back every year for a surveillance audit, so this is a commitment we keep renewing for years to come.
ISO/IEC 27001 certifies how an organisation manages information security, not a product. Ours covers the way we design, build, deploy and maintain software for clients, on both client-managed and our own cloud infrastructure. It also covers the people, processes, cloud-hosted tools and corporate IT systems behind that work.
In practice, that means documented and audited controls for things like access management, supplier security, incident response, business continuity, secure development and how we onboard and offboard people.
You can download the certificate or look us up on IAF CertSearch with the certificate number, 26ISMS-1290.
Getting here took most of the year and a lot of work from people whose day job is building software, not writing policies. Thank you to everyone at MarsBased who drafted procedures, gathered evidence, sat through interviews and fixed what the auditors found.
If you followed the process from the start, this is where we left it. If you have questions about how we handle security, get in touch.

MarsBased is pursuing ISO 27001 certification. Our security practices were already robust. This formalises and validates our commitment to data protection.
