Flexera Software delivers market-leading Software Vulnerability
Management solutions enabling enterprises to proactively identify and
remediate software vulnerabilities, effectively reducing the risk of

Flexera Software supports and contributes to the community in
several ways. We have always believed that reliable vulnerability
intelligence and tools to aid identifying and fixing vulnerabilities
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 vulnerabilities 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 vulnerabilities.
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
Flexera Software.

The public Advisory database contains sufficient information for
researchers, security enthusiasts, and consumers to lookup individual
products and vulnerabilities and assess, whether they need to take
any actions to secure their systems or whether a given vulnerability
has already been discovered
