TYPO3 Professional Open Source
A Trusted Community, A Secure Ecosystem
Independence, transparency, long-term stability. TYPO3 delivers open source with the structure and reliability public institutions and enterprises of any size require.
Open Source, Professionally Managed
TYPO3 combines the freedoms of open source with the discipline of a structured development organization.
A non-profit association oversees the project’s long-term direction, while the TYPO3 company provides commercial services and operational continuity. The contributor community — agencies, developers, integrators — anchors TYPO3 in real-world practice.
Releases follow a fixed schedule, and each major version receives up to seven years of support, including optional Extended Long-Term Support. This predictable lifecycle allows IT teams, agencies, and procurement units to plan multi-year roadmaps confidently.
Roadmap
The TYPO3 CMS development roadmap follows an 18-month release cycle for Long Term Support versions.
Open Source Security, Practiced Professionally
Security is a core responsibility within the TYPO3 ecosystem.
TYPO3’s dedicated Security Team operates with defined workflows for reporting, reviewing, and publishing fixes. As a CVE Numbering Authority (CNA), TYPO3 is trusted to assign official CVE identifiers.
This level of transparency and responsibility supports organizations working under NIS2, CRA expectations, and stricter supply-chain requirements. TYPO3’s recognition as a Digital Public Good further strengthens its position for public-sector digital strategies built around openness, verifiability, and long-term independence.

Reflecting its Commitment to Open Source Values
Enterprise Open Source in Daily Operations
TYPO3 gives organizations freedom without fragmentation.
It can be hosted on-premise, in private or sovereign clouds, or through managed service providers. The extension ecosystem, open APIs, and standards-based architecture (PHP, Symfony, Composer, PSR guidelines) make TYPO3 maintainable and easy to staff.
The partner network — supported by certifications for developers, integrators, editors, and consultants — helps organizations identify qualified service providers and reduce project risk.
In practice, this means:
- independence from proprietary clouds and single vendors
- extensibility through open standards
- straightforward staffing and onboarding for PHP developers
- reliable partner selection through association memberships and certifications
