Skygge is an independent security testing practice. We attack your software and hardware the way an adversary would — escalate every signal to real impact, and hand you a reproducible proof. Not a theoretical risk rating.

What we do
Engagements
Scoped to your threat model, priced to the work — not the clock.
Hardware
Hardware security testing
Firmware, embedded & IoT devices and secure elements — extraction, fault injection, side-channel and protocol attacks, down to the silicon.
Research
Vulnerability research
Deep, multi-pass study of a target until the critical bug surfaces. We don't stop at the first medium.
Proof
Proof-of-concept exploitation
Every finding shipped with a working, reproducible PoC and an honest blast radius — so your team can confirm it in minutes.
What a finding looks like
Proof, not theory
You get the same package an attacker would assemble — only handed to you first.
- A reproducible script that fires the exploit on demand
- A recorded walkthrough a triager can follow on one watch
- The concrete impact — what was read, moved, or bypassed
- A fix, scoped to the root cause, not the symptom
