Webinar: The Truth About Security In Open-Source CMS – For Enterprise Leaders

Who better to tell that truth than someone who’s helped secure a nation’s digital infrastructure in a time of geopolitical crisis?

26 August 2025 | 5 PM CEST

In this session, you’ll hear from Zoja Antuchevič, former advisor to Lithuania’s national cybersecurity infrastructure – one of Europe’s most resilient digital defense strategies in the face of increasing threats tied to the Russia-Ukraine conflict. With over 15 years of experience in IT security, Zoja now serves as CEO and Partner at SolutionLab and is an active member of Umbraco’s Security Team.

She’ll be joined by Emma Burstow, Director of Developer Relations at Umbraco, and Chris Osterhout, VP of Strategy at Diagram (USA), to explore what enterprise-grade security really looks like in the open-source CMS space.

Together, this expert panel will challenge the persistent myth that open-source platforms are less secure than proprietary alternatives – and unpack what today’s enterprises should truly be prioritizing when choosing a CMS. 

From encryption and compliance to transparency, architecture, and practical implementation, this session will give you a grounded, honest, and forward-looking perspective on open-source security in 2025.

What You’ll Learn:

✔️ Why open source is often more transparent and secure than closed systems

✔️ How Umbraco aligns security practices with enterprise expectations and regulatory standards

✔️ What questions enterprise leaders should ask when evaluating CMS platforms

✔️ How security and developer freedom can go hand-in-hand in open architectures
