What our clients say.

Hired them to look at our app before launch. Found 12 issues we had no idea about. Worth every penny.

Good report, took a bit longer than expected to schedule but the actual work was solid.

We had a breach and these guys were on it within hours. Helped us figure out exactly what happened and how to fix it. Would definately use again.

fast and thorough

Found stuff our other security company completely missed. Really impressed.

Helped us understand what SOC 2 actually requires.

Actually enjoyable process. Never thought I'd say that about a security audit.

Excellent mobile forensics work for a family law matter. WhatsApp messages and location data extracted cleanly with full chain of custody. Court-ready report accepted without challenge. Professional and discreet throughout.

Ryan audited our AI-generated codebase and found 14 critical vulnerabilities in a Bolt-built SaaS app we were about to launch. Passwords stored in a JSON file, no server-side auth, SQL injection in every form. Saved us from a very public breach.

Commissioned a vendor validation of our Darktrace deployment. ShadowTap testing revealed 3 detection blind spots we had no idea existed. Darktrace support could not explain why their product missed the test traffic. Eye-opening.

Engaged Sherlock after a ransomware incident. Response within 2 hours on a Saturday. Had our systems triaged and containment plan executed by Monday morning. Cannot overstate how critical that speed was for our business continuity.

Third year working with Sherlock for our PCI compliance testing. They know our environment and catch things every year that we thought we had fixed. The consistency and institutional knowledge is what keeps us coming back.

Used the Quick Audit for my startup before our seed round. Found hardcoded API keys and a broken auth flow that my Cursor-generated code introduced. $1,500 well spent considering what an investor security review would have uncovered.

Our insurance broker recommended Sherlock for our annual pentest. Report was accepted by our carrier without a single question. Renewed our policy at a lower premium as a direct result.

Hired Sherlock for a forensic examination after an employee data theft. Chain of custody documentation was impeccable. Ryan testified as expert witness and the judge accepted every finding. Case won.

Solid pentest of our e-commerce platform. Found a payment flow manipulation vulnerability that could have cost us significantly. Only reason for 4 stars is scheduling took a bit longer than expected, but the actual work was thorough.

Ryan found an auth bypass in our SaaS API that three different automated scanners missed. The report was detailed enough that our developers fixed everything in two days. Exactly what we needed for our SOC 2 audit.
