# CMS Monitoring — Know What Your Site Is Really Running

Every site exposes a technology fingerprint: the CMS, its telltale paths, headers and markup. WatchFor detects that fingerprint on schedule and alerts you when it changes unexpectedly — an early signal of a botched deploy, migration drift, or something more malicious.

## Fingerprint checks with a purpose

Detection first, change alerts always.

### CMS detection

Identifies the platform a site presents — WordPress, Drupal, Joomla, and other common systems — from its public fingerprint.

### Expected-platform assertion

Tell the monitor what the site should be running — if detection stops matching your expected platform, an incident opens. A site that suddenly 'becomes' something else usually has a story to tell.

### Migration verification

Replatforming? The monitor confirms the new stack is what production actually serves — everywhere, not just on the box you tested.

### Multi-region checks

Fingerprints are checked from several regions, catching cache layers or split deployments serving different versions of your site.

### Confirmed alerts

Changes are verified before an incident opens, so a transient cache quirk doesn't page anyone.

### History of what changed when

A timeline of fingerprint changes — invaluable when reconstructing what happened during a messy release.

## Why watch a CMS fingerprint?

Your site's technology fingerprint should be boring: it changes when you migrate, and never otherwise. When it changes on its own — a different CMS suddenly detected, platform markers vanishing, an unexpected version surfacing — something happened that you didn't plan. That's exactly the kind of signal worth an automated watcher.

## How CMS monitoring works

Fingerprint, compare, alert.

1

### Add the site

Point WatchFor at any public site — yours, a client's, or one in your portfolio.

2

### We detect the fingerprint

Each check inspects the site's public technology markers and identifies the CMS it presents.

3

### Changes get confirmed

When the detected fingerprint differs from the last known one, the change is verified from multiple regions.

4

### You get an alert with context

See what was detected before and after, and when the change first appeared.

## Who needs CMS monitoring

From security signal to portfolio oversight.

### Security-conscious site owners

A fingerprint that changes without a deploy is a red flag worth investigating immediately — defacement and injected platforms get caught early.

### Agencies with many client sites

One monitor per site keeps a live inventory of what each client runs — and flags the day a site unexpectedly changes underneath you.

### Teams mid-migration

Confirm the replatform actually reached production everywhere, and that no region or cache still serves the old stack.

### Ops teams inheriting estates

Acquired a portfolio of sites? Continuous detection documents what's really running, without logging into anything.

## CMS monitoring FAQ

Common questions about fingerprint monitoring.

What is CMS monitoring? CMS monitoring detects the content-management platform a site publicly presents — its technology fingerprint — on a schedule, and alerts you when that fingerprint changes unexpectedly.

Why would the fingerprint change without a deploy?

Which platforms can be detected?

Can I monitor sites I don't own?

How often are checks performed?
