The team

The people behind every engagement

Our founder and our compliance team are public; the operators who run engagements are not. They work sensitive engagements for government-adjacent and highly regulated clients, where public exposure would undermine the OSINT resistance we help our clients build.

Our mission

Enterprise-grade testing, without the enterprise gatekeeping

Invadel was founded in 2023 by a team of cybersecurity veterans who believed strong security shouldn’t be a luxury reserved for the largest corporations.

We set out to make expert, manual-led penetration testing accessible to organizations of every size, from early-stage startups to regulated enterprises.

That mission hasn’t changed. We’ve helped businesses across finance, healthcare, SaaS, and beyond strengthen their security posture, navigate complex compliance requirements, and defend against evolving threats, with fixed-scope engagements and a free retest included with every penetration test.

Our goal is simple: prove where you’re exposed before an attacker does, and give your team a clear path to close it.

What we believe

Principles that shape every engagement

Findings over noise

A ten-page report of real, exploitable issues beats a hundred pages of scanner output. We report what matters and say so plainly.

Testing is a craft

Our testers research, build tooling, and chain vulnerabilities the way real adversaries do. Automation assists; it never substitutes.

Straight answers

If something is out of scope, risky to test, or not worth your budget, we tell you before the engagement, not after.

Partners, not vendors

The engagement ends when your fixes are verified, not when the report is delivered. Retesting is part of the job.
