Why you cannot wait: Kentico 13 end-of-life explained

End of life is not a soft cutoff. From 1 January 2027, every new vulnerability in Kentico 13 stays unpatched. Here is what that actually means for your organisation.

01

Security without support

Once patches stop, new vulnerabilities in Kentico 13 become your problem, not Kentico's. The Australian Cyber Security Centre has flagged large-scale exploitation of unsupported CMS platforms targeting Australian businesses.

02

Insurance and compliance exposure

Cyber insurance policies increasingly exclude incidents on end-of-life software, so a breach after the deadline may not be covered. Privacy Act obligations are also harder to defend when your site runs on unsupported software.

03

Specialist capacity is filling

Experienced Kentico migration partners book out well ahead of the deadline. Starting early means more partner choice, more timeline flexibility, and room to handle unexpected complexity.

04

It is a rebuild, not an upgrade

Xperience by Kentico is a rebuilt platform: different content model, delivery architecture and tooling. Migration is a proper project with content mapping, template rebuild, integration and testing, which is exactly why it needs time and an experienced partner.

Kentico 13 end-of-life: what actually happens on 1 January 2027

End-of-life doesn’t mean your website switches off it keeps running. What stops is Kentico’s support: from 1 January 2027, Kentico 13 receives no security patches, no bug fixes and no vendor assistance. Any new vulnerability discovered after that date stays open on your site. It becomes your problem, not Kentico’s. For organisations that get security-audited local government, health, finance running unsupported software is also a compliance and cyber-insurance exposure.

The fix is Xperience by Kentico, and it’s evergreen. Instead of a big-bang version every few years, Xperience ships continuous updates so once you migrate, there is no next end-of-life date to plan around.

Phil Allen (Founder & Chief Strategist at Dapth) has been working with Kentico for over 10 years. This is his take on the biggest structural change he has seen in how the platform works.
