TYPO3 delivers open source with the structure and reliability public institutions and enterprises of any size require. [ Talk to an Expert ](https://typo3.com/partners "Talk to an Expert") Why TYPO3? ------------ Be ready for future demands ------------------------------- Digital infrastructure decisions carry long-term consequences. Organizations need technology they can understand, trust, and maintain — without being tied to a single vendor or platform. TYPO3 offers professional open source: transparent code, a stable governance model, [predictable development cycles](https://typo3.com/typo3-cms/why-typo3/security-stability), and an ecosystem of [qualified partners](https://typo3.com/partners). It supports long-term planning in environments shaped by compliance, sovereignty strategies, and rising security expectations. 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](https://typo3.com/products-services/extended-support-elts). This predictable lifecycle allows IT teams, agencies, and procurement units to plan multi-year roadmaps confidently.

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](https://en.wikipedia.org/wiki/Cyber-security_regulation#NIS_2_Directive), 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. #### TYPO3 Recognized as a Digital Public Good ##### Reflecting its Commitment to Open Source Values [ ![](https://typo3.com/fileadmin/_processed_/6/a/csm_dpg2_445303e74a.webp) ](https://typo3.com/fileadmin/TYPO3_CMS/Why_TYPO3/professional_open_source/Digital_Public_Goods_%E2%80%93_Quick_Guide.pdf) Click to download our PDF Quick Guide Enterprise Open Source in Daily Operations -------------------------------------------- ### TYPO3 gives organizations freedom without fragmentation.

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](https://typo3.com/typo3-cms/why-typo3/flexibility-scalability) through open standards - [straightforward staffing and onboarding ](https://typo3.com/typo3-cms/what-is-typo3)for PHP developers - reliable partner selection through [association memberships](https://typo3.org/association/membership) and [certifications](https://typo3.com/products-services/certifications) Open Source ------------- Learn how TYPO3’s open-source model ensures transparency, flexibility, and innovation.
