Vulnerability Research & Exploit Dev

Find the bugs no one has reported yet.

Original vulnerability research and exploit development against software, devices and protocols — the same work behind our published CVEs, applied to the products you ship or rely on.

Proven, not aspirational

Most testing checks for known issues. Research finds the unknown ones — in your own product, in a dependency, or in a device you rely on. Our team does this for real, with CVEs published across widely-used software.

We develop proof-of-concept exploits where they're needed to prove impact, and support coordinated disclosure when research touches third parties.

What we research

  • Web, API and application internals
  • Thick-client and desktop software
  • IoT and embedded devices
  • Protocols and file formats
  • Third-party dependencies
  • Proof-of-concept exploit development

How it works

  1. Define the target

    We agree the product, depth and disclosure approach.

  2. Research

    Deep manual analysis, reversing and fuzzing as needed.

  3. Prove

    We develop PoCs to demonstrate real impact.

  4. Disclose

    Findings to you, and coordinated disclosure where relevant.

What you receive

Clear deliverables, agreed in the proposal, with no surprises at the end of the engagement.

  • Research findingsDocumented vulnerabilities with technical detail.
  • Proof-of-conceptWorking PoCs that demonstrate real impact.
  • Remediation guidanceConcrete fixes and hardening advice.
  • Disclosure supportCoordinated disclosure handling where needed.
