See your security through an attacker's eyes.

We simulate real adversaries across your entire attack surface and validate what could actually be exploited - then hand you the exact path to fix it. No checkbox audits, just risk you can act on.

Illustrative engagement - every instX test is run by hand against your real environment.

More than a test

We don't hand you a report and disappear.

A pentest is a moment in time. Risk is ongoing. instX acts as your offensive security partner across the full lifecycle - from the first engagement to annual retests, continuous programs, and board-ready reporting.

Findings you can act on

Every finding is validated by hand, risk-ranked and paired with step-by-step remediation guidance your developers can follow immediately.

Free retest included

After you fix, we come back at no extra cost to verify the issues are genuinely closed - not just patched on the surface.

Reporting for every audience

Technical depth for your engineers. Executive summary for your board. Risk matrices for your auditors. One engagement, three tracks.

Continuous security programs

Move beyond point-in-time tests. Our retainer programs give you scheduled engagements, priority response and a persistent offensive security partner.

Engagement packages

Choose the engagement that fits your risk

Every package delivers manual testing by senior offensive security engineers - not automated scans. Scoped to your environment, priced on engagement depth.
