TYPO3 Security Monitor: Automated Extension Security Monitoring

TYPO3 Security Monitor: monitor 800+ extensions, detect vulnerabilities. Free check available.

What is the TYPO3 Security Monitor?

The Gosign TYPO3 Security Monitor automatically checks over 800 TYPO3 extensions for security vulnerabilities, outdated versions and known weaknesses. When an extension receives a security advisory, Gosign clients know immediately - not at the next manual check. The monitor is a proprietary Gosign tool that continuously evaluates TYPO3 security bulletins, extension changelogs and CVE databases.

Why do TYPO3 operators need security monitoring?

TYPO3 installations typically use 30-50 extensions. Each one is a potential attack vector. The TYPO3 Security Team regularly publishes advisories, but who reads them all? Gosign's monitor does exactly that - automatically and in real time.

What the monitor checks

Area	What is checked	Frequency
Extension versions	Installed vs. current version	Daily
Security advisories	TYPO3 security bulletins, CVE databases	Real-time
End-of-life	Extensions without maintainer or updates	Weekly
TYPO3 Core	Core version vs. current Stable/LTS	Daily
PHP version	Compatibility and security status	Weekly
