A note from the founder

Why I built Pentest Express.

I have been performing penetration tests for fifteen years. In that time I have watched the same problem repeat itself across hundreds of engagements: a company needs an external pentest for compliance, calls three vendors, sits through three scoping meetings, waits two weeks for proposals, and ends up with either a $30,000 invoice or a $2,000 report full of false positives that an auditor will not accept.

Neither of those is the right answer. The first one wastes money the company should be spending on actually fixing things. The second one wastes the auditor's time and creates real risk because the buyer thinks they have been tested when they have not.

Pentest Express exists because most external network pentests are not actually that complicated. They are repeatable, well-defined work that benefits from a senior tester following a rigorous methodology. They do not benefit from a sales process, a custom SOW, or a tiered "platform." Those things exist to extract more money from buyers, not to produce better outcomes.

So I built the version of this service I wish existed when I was on the buyer side. Pricing is published. Scope is fixed. Manual validation is included on every engagement. There is no sales call. The report is written in a format that auditors recognize. And the person who finds the issues is the person who wrote the report, which, for now, is me.

If you need anything more involved than an external penetration test, internal testing beyond compliance, application testing, red team, custom scoping, that work goes to my parent company, Verification Labs. Pentest Express is deliberately narrow. That is the entire point.

Background

Fifteen years across the work that defines this field.

Hands-on technical depth, large-scale security operations, and extensive speaking and training experience across advanced security topics for some of the world's largest corporations and governments.

Trey has provided penetration testing and assessment services to hundreds of clients across the financial, government, retail, chemical, aviation, oil & gas, medical, educational, legal, telecom, and law enforcement sectors.

He has trained numerous Fortune 100 companies, consulting firms, and federal agencies — including the DIA, FBI, and NSA on network security, system security, attack and penetration testing, and cloud security. He has performed thousands of penetration tests for Fortune 500 companies globally across various infrastructure devices, operating systems, protocols, and applications.

He speaks frequently about advanced security topics at financial institutions and Fintech conferences in the US, Europe, and Africa. He has spoken at DefCon and MITRE ATT&CKcon, and delivered two keynotes at the Department of Homeland Security's annual CISA conferences.

Trey currently serves on several forensic, red-team, and penetration-testing advisory boards, and is a frequent television and podcast guest on topics including ransomware, deepfakes, supply-chain attacks, and the weaponization of AI.
