Management solutions enabling enterprises to proactively identify and

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
