"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."
Indigo, Baseline
"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."

How it works

Repo in. Scan out. Three steps.

Step 1 Drop your repo

Connect the GitHub repo or paste a contract address - Sentry takes it from there.

Step 2 Sentry scans it

Static, symbolic, and pattern-based passes run in parallel against the Guardian rule set.

Step 3 See the findings

Get a categorized list of issues with severity, affected files, and a fix-it-first ranking.

Why Sentry

An automated scan with real auditor pedigree

Most scanners are noisy. Sentry is calibrated against the rule sets and invariants Guardian uses on $50B+ in client TVL.

01

Trained on Real Audits

Detection rules distilled from five years of Guardian engagements - not generic OSS heuristics.

02

Low False-Positive Rate

Findings are pre-triaged by trained agents so you don't drown in nits before you find the bug.

03

Upgrade Path

Anything the scan flags can be escalated to a full Guardian audit with one click.

"Having seen many audits over many years, no one even comes close to Guardian's approach, and the quality of the audit is unmatched."

"Guardian demonstrated professionalism and attention to detail second to none. They identified issues our other auditors missed."

FAQ

Common Questions

How fast is the scan?

Most repositories finish their first pass in under 30 minutes. Larger codebases may take up to a few hours.

What do I get back?

A categorized findings list with severity, file/line references, and remediation hints - delivered by email and Telegram.

Is it actually free?

Yes. The automated scan is free. A full human audit is a separate, quoted engagement.
