Concrete CMS websites, upgrades and support
An open-source CMS where editors change content on the page itself.
When to call us
When your Concrete site is falling behind
If your site is on concrete5 or version 8, it hasn't had a security fix since March 2026. We'll upgrade it, rebuild it on version 9, or help you move on.
Your site still runs concrete5 or version 8, and nobody has upgraded it.
Your editors like editing on the page, but the site looks dated and runs slowly.
You run several brands or regions and want them on one install.
You're deciding whether to upgrade Concrete or move to another CMS.

Questions
The things people usually ask
Plain answers on how Concrete CMS works, what it costs and what we need from you. Anything else, just ask.
Is concrete5 the same as Concrete CMS?
Yes. concrete5 was renamed Concrete CMS with version 9, which is the current version.
Is our version 8 site still safe?
Not for long. Concrete stopped backporting security fixes to version 8 in March 2026, so new vulnerabilities won't be patched. Version 9 is the supported line.
Should we upgrade or rebuild?
It depends on your add-ons, custom code and hosting. Older sites often have to be upgraded one version at a time, and a clean rebuild on version 9 can be quicker. We'll look at your site and tell you which.
Can one install run several brands or regions?
Yes. Concrete can run several sites, brands or languages from one install. We built Bottomline's multi-region site and Hornby's multi-brand platform on it.
Where should it be hosted?
Anywhere that runs PHP well. Concrete's own hosting is an option, but its cheaper plans don't give you access to the code, so check before you move.
