Sqreen logo

Sqreen protects distributed applications against sophisticated attacks by automatically detecting and tracing vulnerabilities down to the line of code. Acquired by Datadog.

Security is shifting-left - from the security team to the development team, but developers often don't have the expertise in making systems secure. The only way for security to become ubiquitous is for it to be as easy as adding a few lines of code.

Sqreen, based out of Paris, was founded by Pierre Betouin and Jean-Baptiste Aviat, who both previously worked at Apple's Red Team.
