Management solutions enabling enterprises to proactively identify and

Flexera Software supports and contributes to the community in

intelligence and tools to aid identifying and fixing Vulnerability
should be freely available for consumers to ensure that users,
who care about their online privacy and security, can stay secure.
Only a few vendors address Vulnerability in a proper way and help
users get updated and stay secure. End-users (whether private
individuals or businesses) are otherwise left largely alone, and
that is why back in 2002, Secunia Research started investigating,
coordinating disclosure and verifying software Vulnerability.
In 2016, Secunia Research became a part of Flexera Software
and today our in-house software vulnerability research remains the
core of the Software Vulnerability Management products at
