Thick Client Testing

Secure your desktop applications with advanced thick-client testing. We thoroughly assess client-side binaries, local storage, and the client-server trust boundary to identify critical vulnerabilities that web-focused testing misses.

Every finding is rated on the CVSS severity scale:

  • CRITICAL9.0–10.0
  • HIGH7.0–8.9
  • MEDIUM4.0–6.9
  • LOW0.1–3.9
  • INFO0.0

Questions we hear a lot.
