Respected as #1 in digital asset security for 5 years.
Guardian's commitment to high quality audits, keeping up with industry best practices and alignment between the auditors and the protocol has led to them being a highly valuable partner in improving security of the protocol
10/10 They are hands down some of the absolute best security minds in the space. This is how auditing DeFi protocols should be.
10/10, Guardian has throughly evaluated our EVM implementation and has identified design flaws that AI agents can hardly identify.
Guardian demonstrated professionalism and attention to detail second to none. They identified issues our other auditors missed.
Having seen many audits over many years, no one even comes close to Guardian's approach, and the quality of the audit is unmatched.
Even with our super tight timeline, Guardian was professional, quick, and thorough, delivering high-quality work right on time. By far the best team we've worked with.
Our experience with Guardian has been amazing. All security researchers on the team were exceptional at understanding all intricacies of the design and the team is well suited to audit any novel DeFi product that comes their way.
Guardian has been an integral part of the growth of GMX and our ecosystem of protocols who also rely on them for audits. Having Guardian as a strategic partner has allowed us to move more quickly while keeping security as our highest priority.
Guardian auditors conducted a remarkably thorough review. Their approach was well structured and we greatly appreciated the speed and professionalism of their feedback.
My team and I have worked with many auditors in the past, including generally considered top tier firms. I can confidently say that we have never felt as secure as when working with Guardian.
Guardian found a key bug that had been missed in previous audits, despite being outside the audit's scope. This is an honest signal of commitment and going the extra mile is rare.
Extremely proficient. I feel like they care about their contribution on a personal level. They are on a mission to become the best auditors out there. They don't need much guidance and understand the codebase quickly.
Guardian has an impeccable eye to detail and goes above and beyond to ensure that the code is watertight. They are able to assess super advanced Solidity inline-assembly with ease.
We were impressed with Guardian's overall approach to security, focus on tests, attention to detail and streamlined audit process. We enjoyed working with them.
In our previous engagements, the Guardian team was extremely thorough. I also felt that the two-team approach would give a more in-depth coverage of our codebase.

The Guardian Model
Two independent teams, maximum security outcome.
One team pushes AI systems to their limits while another focuses on manual analysis and deep fuzzing.
Competitive incentives reward performance, and each team cross-checks the other so the final result is stronger than either workflow alone.
