php2shell Response: Lessons for PHP Teams from Pantheon

When a critical vulnerability hits, can your web team respond quickly without going into crisis mode?

Join Pantheon's Co-founder Josh Koenig, Director of Engineering William Burke and Principal Developer Advocate Steve Persch for a deep-dive on PHP security, vulnerability response, and the php2shell incident. Get a behind-the-scenes look at how security and engineering teams respond when a critical PHP vulnerability puts web applications at risk.

Learn how Pantheon monitored threats, applied runtime and network-level mitigations, and patched hundreds of thousands of PHP services in a few hours. Josh will also discuss how AI is accelerating exploit timelines, and the incident-response and software-development practices PHP teams can use to reduce exposure, keep workflows moving, and avoid creating new problems under pressure.

If you work with PHP applications, web infrastructure, or application security, this conversation offers a practical look at what effective vulnerability management can involve.
