Security firms are easy to evaluate on their marketing and hard to evaluate on their work. These are engagements where ours was visible.
In April 2023 our monitoring caught an approval bug in SushiSwap's RouteProcessor2 contract. We opened a war room with the Sushi team that night and deployed a cross chain watcher to front run the attackers across eight chains, recovering funds that were already being drained.

These are different services that find different problems. Here is the honest guide, so you buy the one that fits where you are rather than the one with the biggest name.
You have written smart contracts and want them reviewed line by line before they hold real money. Findings classified critical to minor, with up to two rounds of remediation review included.
Smart Contract AuditsYour product is running and you want to know what an attacker could actually take, across contracts, APIs, wallets, front ends and infrastructure rather than the code alone.
Penetration TestingYou have monitoring and a security team, and the real question is whether they would detect a determined adversary. Full spectrum simulation across technology, people and physical access.
Red Team and Adversarial SimulationYou have models, agents or AI generated code in production and need the offensive testing, defensive controls and observability that conventional security tooling does not cover.
AI SecurityNot sure? Most protocols need an audit before launch and a penetration test once live. Tell us what you have built and we will tell you honestly what is worth doing, including when the answer is nothing yet.
