Incident Timeline
Monitoring
Earlier today we took Teamleader Focus offline as a precaution. The PHP foundation had announced two critical security vulnerabilities in PHP, a technology our platform runs on, and we didn't want to wait for the official fix while exposed.
The official fix was released today and we have now installed it across our platform. All services are available again.
Our investigation has found no evidence that these vulnerabilities were used against Teamleader. That investigation is still ongoing, and we will update this page if anything changes.
Thank you for your patience. If you notice anything unusual, please contact our support team.

Identified
Teamleader Focus is unavailable at the moment. We took it offline on purpose.
Two critical vulnerabilities were made public in PHP, the programming language behind many websites and web apps worldwide, including Teamleader Focus. To stay ahead of any risk, we switched off Teamleader Focus as a preventive measure. We’re not aware of any security issues or misuse, and our team is investigating to be fully sure.
When will we be back?
For now, we’re aiming to make Teamleader Focus available again at 19:00 CEST. We can’t confirm yet whether that will be possible any sooner, because we first need to take the necessary steps to bring it back online safely. We’ll keep you posted on this page.
Thanks for your patience, and sorry for the inconvenience.
