Advanced fuzzing harnesses for software that cannot fail

Our engineers work closely with your team to design a fuzzing strategy that zeroes in on bugs that matter most. The harnesses we deliver are yours to keep: run them locally or on our infrastructure, KaaS, for continuous assurance long after the engagement ends.

You set the goals, we do the rest

From your first design review to a dedicated AI agent running your fuzzing harness long after we're done. Our engineers handle the complexity so you can focus on shipping.

Step 01

Design review

We dive deep into your codebase to map its most critical properties. The foundation every good fuzzing campaign is built on.

Collab work
Step 02

Fuzzing harness specification

Designing an effective harness for your codebase, maximizing coverage of key critical properties with the right techniques.

Manual work AI assisted
Step 03

Manual code review

Our engineers perform a formal methods-based code review, augmented by in-house AI tooling, to catch what automated fuzzing alone can miss.

Step 04

Running your campaign and results with KaaS

Free infrastructure to run your fuzzing campaign with comprehensive, easy-to-read reports.

KaaS-powered
Step 05

Continuous security with a dedicated AI agent in KaaS

Re-run campaigns anytime and deploy AI agents to triage and remediate issues, so your security posture keeps improving after our engagement ends.
