ISO 27001

Every B2B software website has a row of certification badges somewhere in the footer. Most visitors scroll past them. But if you're the person filling out a security questionnaire, responding to an audit, or evaluating vendors for a tender — those badges are suddenly the whole conversation. So let's skip the logo wall and explain what ISO 27001 actually is, and what it buys you when it belongs to the company running your email.

ISO/IEC 27001 is the international standard for information security management systems — an ISMS. It doesn't certify a product; it certifies that an organization runs a systematic, audited process for managing information security risk: identifying threats, applying controls, reviewing them, improving them, repeat. Independent auditors verify it, and it's re-audited on a cycle. A certificate on the wall means the processes behind the product are real, documented and externally checked.

Here's the part that gets lost in badge collections: our certification becomes your evidence.

Vendor due diligence. When your security team assesses suppliers, "the vendor holds ISO 27001" is the answer that closes the question. You'll find it as a line item in virtually every enterprise security questionnaire.

Tenders and procurement. Public and enterprise tenders increasingly list ISO 27001 as a requirement for suppliers of communication infrastructure. A certified platform keeps you eligible.

Your own audits. If your organization works toward ISO 27001, NIS2 or similar frameworks yourself, your suppliers' certifications are part of your documentation. Under NIS2's supply-chain requirements, they're explicitly expected.

A security posture that isn't self-declared. Anyone can write "we take security seriously." Certification means someone independent checked.

IceWarp holds ISO/IEC 27001 certification for its information security management system, alongside an independent SOC 2 Type II audit report (covered in a companion article). Our data center facilities add their own layer, the Prague site, for example, operates at Tier III with its own ISO certifications including 27001.

If you need the certificate or supporting documentation for your audit file, your procurement process or your security questionnaire — contact our team and we'll provide it.

The bottom line

ISO 27001 isn't a decoration. It's the difference between "trust us" and "here's the audit." When the platform handling your organization's communication can show certified, externally verified security processes, your next questionnaire, tender and audit gets shorter.

Is IceWarp ISO 27001 certified? Yes. IceWarp holds ISO/IEC 27001 certification for its information security management system, independently audited and renewed on the standard's cycle.

Can we get the certificate for our own audit or tender? Yes. Contact our team and we'll provide the certificate and supporting documentation for your audit file, procurement process or security questionnaire.

What's the difference between ISO 27001 and ISO 27017/27018? ISO 27001 certifies the overall information security management system. ISO 27017 and 27018 are companion guidelines focused on cloud security controls and protection of personal data in the cloud, respectively — they build on the 27001 foundation.

Does the certification cover cloud and self-hosted? The certificate covers IceWarp's organizational processes. Ask us about the specific scope — we'll tell you exactly what it covers, which is the answer you should expect from any vendor.

Does our provider's ISO 27001 make us certified? No — certification is per-organization. But a certified supplier is documented evidence in your own compliance work, and under frameworks like NIS2, your suppliers' security posture is part of what you're required to assess.
