We find what others miss.
Elite security engineers who think like attackers, not consultants who run scanners. For two decades, we’ve found the critical flaws automated tools and other testers walk right past.
We find the risks that actually threaten your business.
For twenty years, organizations have called us when checkbox security isn’t enough, including, quietly, some of the largest names in the industry. We don’t just hand you a report and move on. We find the vulnerabilities that could actually harm your business, show you how an attacker would exploit them, and help you close them, so passing the test means you’re secure, not just compliant.
Senior-led, always
Every engagement is run by a senior engineer who exploits for a living. No junior analysts cutting their teeth on your network.
Real attack paths, not scanner noise
We chain vulnerabilities the way attackers do and prove impact, then hand your team findings they can actually act on.
Depth where others stop
IoT, embedded, hardware, and AI security are core to us, not afterthoughts. We go where most firms can’t.
Two decades of trust
Securing organizations since 2006 across finance, healthcare, government, and technology, under strict confidentiality.
Human-led. Argus-amplified.
Every engagement runs on Argus, our proprietary AI engine, built and operated in-house. It works alongside our engineers, expanding coverage and surfacing leads faster than any human could alone, so our experts spend their time where it counts: turning real vulnerabilities into proven, exploitable impact. Scanners can’t replace expertise. Argus amplifies it.
Argus covers the breadth
It works your full attack surface in parallel, faster and wider than a person testing alone, and it never gets tired or cuts corners.
Our experts own the depth
Every lead is validated, exploited, and judged by a senior engineer. You get proven impact, not scanner noise or AI guesses.
You get both
The reach of automation with the judgment of seasoned engineers, in a single engagement. More found, found faster, and nothing important missed.

A test costs a fraction of a breach.
The cheapest line in your security budget is finding the flaw before someone else does. Here is the trade you are actually making.
- Days, not months
- You set the scope and the timeline
- Fixed before anyone can exploit it
- 241 days to identify and contain*
- Regulators, insurers, and customers set the timeline
- Disclosed, reported, and remembered
* IBM Cost of a Data Breach Report 2025: U.S. average breach cost $10.22M (record high); global average $4.44M; mean time to identify and contain 241 days.
