OBSIDIAN is the elite offensive security studio behind hard systems. Binary analysis, protocol audits & adversary simulation — engineered for teams that can't afford a breach.
Built around what you do best — offensive research. No retainer fog. Fixed scope, fixed price, fixed timeline. Ship the report, ship the fix, ship with confidence.
For teams shipping compiled code, firmware, or closed binaries. We tear it down to the metal.
Smart contracts, bridges, and Web3 infra. The bugs that drain treasuries before launch.
We attack like the real adversary — without touching prod. Private lab, real TTPs.
Fast, sharp, no fluff — like you work. Every engagement runs the same battle-tested pipeline.
Fixed price from code size & attack surface. NDA signed, repo access, threat model draft day 1.
Manual review + fuzzing + invariant attacks. Daily log in your Slack. No black box.
Every critical gets a working PoC + video. You see the exploit before an attacker does.
Patch guidance, re-audit included, and a deploy gate checklist. Launch with proof.
No hourly creep. You pay for outcome: findings + PoCs + fix review. Most teams start with Express.
For MVPs & pre-launch checks. 3-5 days.
For protocols & funded teams. 7-10 days.
For enterprises & high-value TVL. 2-3 weeks.
"OBSIDIAN found a reentrancy we missed after two prior audits. PoC in 48 hours, patch in 12. Saved our launch."
"The binary report was the best we've ever received. Actual ROP chain, not just 'theoretical overflow.'"
No hunting on live programs without scope. We triage your HackerOne reports, kill duplicates with our ScopeHawk filter, and surface only direct-impact bugs.
Express starts in 24-48h after scope lock. Standard/Forge within a week. We cap at 3 concurrent audits to keep quality hard.
You still get the full artifact — coverage, invariants, and a launch gate sign-off. That's the point. Proof of hardness is the deliverable.
