Intelligent Fuzz Testing
Detect bugs that other tools miss
The number of ways to misuse a system is infinite, however your resources to test for security issues are not. Our intelligent fuzz testing tool, Defensics, helps you effectively and efficiently “shrink” your security problem to a manageable size by reducing the infinite pile of misuse cases to those that matter the most.
We uncovered Heartbleed
Defensics was used to identify the OpenSSL Heartbleed vulnerability, which had gone unidentified for over two years and impacted over 500,000 websites.
