The incumbents
90d
Point-in-time tests, or machine noise with nobody reading it. Either way, a report that ages the moment it lands.
Greywatch
24/7
Always-on AI agents with a security engineer proving every finding before it reaches you.
Side by side

4 comparisons

No strawmen. Each of these built something real - the question is whether the model still fits how you ship.

Greywatch vs. Cobalt
Cobalt runs vetted human testers on a project cadence and delivers a report. Deep work - but a 90-day-old report is a historical document, not a security posture.

Greywatch vs. Astra Security
Astra flags what might be wrong across a broad surface. We show you the exact request that worked, the data it exposed, and the fix that closes it.
Read the comparison →
Greywatch vs. security scanners
Scanners find everything and understand nothing. A thousand findings with no prioritization is alert fatigue, not coverage.

Greywatch vs. AI pentest tools
Autonomous agents move at machine speed with no judgment. They cannot tell which finding is existential for your business and which is noise.

The short version

Where each model breaks

Rebut the model, not the company. All 3 are rational answers to the problem as it looked before AI collapsed the cost of attacking you.

Scanners find everything, understand nothing
A thousand findings, no prioritization, no human in the loop. You get alert fatigue and no idea which 3 actually matter.
Pentests go deep, then stop
Real depth, but point-in-time. You ship ~4x a day and get tested ~4x a year. Everything between deploys is unlooked-at.
AI agents move fast, judge nothing
Machine speed without judgment. An autonomous agent cannot tell which finding is existential for your business and which is noise.

What we actually do

If you already know the incumbents and just want the model itself.

Continuous penetration testing
Offensive testing that runs as continuously as the pipeline it tests, instead of once a quarter.

Penetration testing for startups
Built for Series A-C teams holding sensitive data with no dedicated security function in-house.

The journal
Real vulnerabilities we found in shipping products, written up with the request that worked and the fix that closed it.
