CMS detector
See the CMS and server software a site gives away.
What this checks
Many sites announce the software that runs them, through a generator meta tag in the HTML and through response headers like Server and X-Powered-By.
This tool reads the homepage and reports the CMS, generator and server software it finds exposed, along with version numbers where they are published.
Why it matters
A published version number tells an attacker exactly which known vulnerabilities to try, so exposing it is a small but real risk that is easy to remove.
For an agency taking over a site, the exposed software is also a fast way to learn what a client is actually running before you quote the work.
How to fix common failures
Remove the generator tag
Most platforms can drop the generator meta tag, or a plugin or theme setting will hide it.
Trim the headers
Strip or shorten the Server and X-Powered-By headers at the web server or CDN so they do not name a version.
Keep software current
Hiding the version helps, but the real fix is staying patched so a known version is not worth attacking.
CMS detector is one check. Janitor watches exposed CMS and server software automatically across every client site and puts it in a branded report.

FAQ
CMS detector FAQ
Why can the tool not always detect the CMS?
A well-configured site removes the generator tag and trims its headers, so nothing is exposed to read. No detection here is a good sign, not a failure.
Is exposing the CMS actually dangerous?
On its own it is low risk, but it makes a site easier to target. Removing the version is a quick, sensible hardening step.
Can Janitor watch this across many sites?
Yes. Janitor flags exposed CMS and server fingerprints on every client site, so a theme or host change that starts leaking a version is caught.
