Detailed, data-rich reports for efficient remediation

Our comprehensive reports include contextualized logs that detail the protocol path and message sequences, vulnerability mapping to industry standards such as CWE and injection type, and single test cases so you can re-create each issue and verify the fix. You can also generate remediation packages for your suppliers to facilitate secure, collaborative remediation across the supply chain.

Scale fuzz testing with automation

From scanning for the test target to determining the number of layers to connect to, Defensics offers a rich set of APIs for flexible, scalable automation to meet all your needs.

A versatile fuzzer that fits any team’s needs

Procurement

Defensics is a black box fuzzer, so it doesn’t require source code to run. Users can ensure the interoperability, robustness, quality, and security of software and devices before introducing them into IT or lab environments.

Development

Defensics fits nearly any development workflow—whether in a traditional SDL or CI environment. Its API and data export capabilities also enable it to integrate with surrounding technologies, making it a true plug-and-play fuzzer.

Quality assurance

Defensics’ intelligent, targeted approach to fuzzing allows organizations to ensure software security without compromising product innovation, increasing time to market, or inflating operational costs.

Security

Black box fuzzing is one of the top fuzzing security techniques used by adversaries. Use Defensics to uncover zero-day and unknown vulnerabilities before they lead to costly patches and recalls.
Properly executed fuzzing techniques can provide a low-cost, efficient means of finding vulnerabilities, covering more code paths and value iterations than a manual analysis can perform in a short period of time.”
