Teamleader took Focus offline as a precaution after two critical vulnerabilities were found in PHP, the technology used to power websites and web apps. Teamleader did not wait for the official fix. The PHP security update was released the same day, and Teamleader installed it across its entire platform.

Teamleader said its technical teams worked overnight to bring Focus back online. The company said data security is its top priority. The post did not say how many customers were affected or whether any data was accessed.
