Desktop & Thick-Client Penetration Testing
Desktop and thick-client application testing across binaries, IPC, and server communication.
Desktop and thick-client penetration testing assesses installed applications across their binaries, local storage, inter-process communication, and server traffic — surfacing privilege, tampering, and auth-bypass flaws unique to native software.
Where attackers get in — and where we look.
Binary & memory analysis
Local privilege & storage
IPC & DLL abuse
Traffic interception
Auth & licensing bypass
A proof-driven methodology.
Scope & recon
We agree objectives and rules of engagement, then map what you actually expose.
Map the attack surface
Enumerate entry points, roles, and trust boundaries a real attacker would target.
Manual exploitation
Certified testers exploit flaws by hand — chaining issues scanners never connect.
Prove impact
Every finding ships with a working, reproducible proof-of-exploit and business context.
Report & retest
Risk-ranked report with fixes, then a retest that confirms each issue is closed.
Proof you can act on.
Reproducible proof-of-exploit
Every finding ships with a working exploit and evidence.
Risk-ranked report
CVSS + business context, prioritized for your team.
Remediation guidance
Actionable fixes mapped to each finding.
Retest to verified fix
We confirm closure — proof it’s fixed, not assumed.
Make it continuous.
Pair this test with a program that keeps coverage live between engagements.
Desktop & Thick-Client Penetration Testing — questions buyers ask.
What is a thick-client application?
A thick (or fat) client is a desktop app that runs significant logic locally — .NET, Java, or C++ software — often talking to a backend server we also test.
What do you look for that web testing doesn’t cover?
Binary and memory analysis, local privilege escalation, DLL and IPC abuse, licensing bypass, and intercepting the app’s server communication.
Can you test air-gapped or on-prem software?
Yes — we can test in your environment or a provided lab build, including offline and on-prem deployments.
Prove what an attacker could actually do.
A short scoping call, no obligation.
