8) About Flexera Software



Flexera Software helps application producers and enterprises increase

application usage and the value they derive from their software.





http://www.flexerasoftware.com/enterprise/company/about/



Flexera Software  delivers  market-leading  Software  Vulnerability

Management solutions enabling enterprises to proactively identify and

remediate software vulnerabilities, effectively reducing the risk of

costly security breaches.



http://www.flexerasoftware.com/enterprise/products/



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
