What is a pentest?

A pentest, or penetration test, is a controlled attack simulation on your systems. Our Pentest Agent autonomously maps your full attack surface, finds vulnerabilities, safely exploits them and proves the real impact. Certified hackers (OSCP, OSWE) verify quality. You receive a report with reproduction steps, severity ratings and concrete recommendations. First results within 24 hours.

Our approach

How our Pentest Agent works

Our Pentest Agent is trained on years of experience and the proven methodology of our own hackers, not generic AI. It uses the same techniques as real attackers, but autonomously and in hours rather than weeks: it safely exploits vulnerabilities and proves the real impact.

An organisation's attack surface, mapped autonomously
01

Map

The Pentest Agent autonomously maps your full attack surface: applications, APIs, endpoints and data flows.

02

Test autonomously

It attacks, finds vulnerabilities and safely exploits them — broader and faster than is feasible manually.

03

Proof + report

Reproducible findings with proof of impact and concrete fix suggestions, quality-checked by our certified hackers.

Why DEFION

Four things that set us apart

AI speed combined with senior expertise. No scan-and-send reports, no false-positive padding.

Trained on our own hackers

Our methodology

The Pentest Agent is trained on years of experience and the proven methodology of our OSCP/OSWE hackers. Not generic AI, but DEFION expertise at scale.

Hands-on certified hackers

Senior-only

OSCP, OSWE, CEH and CREST. Our pentesters have years of ethical hacking experience and verify the quality of every pentest. No junior consultants.

Reproduction steps + fix suggestions

Directly actionable

Every finding includes a curl command, code patch or step-by-step reproduction. Your dev team can act immediately — no detective work required.

Almost always a way in

Proven in practice

At nearly every organization we test, we find a route a real attacker would also find. No pat on the back for us, but you'll know exactly where to strengthen.

Frequently Asked Questions

FAQ

What is the difference between the Pentest Agent and a traditional pentest?
The Pentest Agent tests autonomously, broadly and within 24 hours. A traditional pentest is fully performed manually by our certified hackers and goes deeper on specific business logic. You can combine both.
Which AI does the Pentest Agent use, and is it EU-proof?
Our Pentest Agent runs on AWS Bedrock in an EU region and uses multiple frontier security models for maximum coverage. Your data stays within the EU, is not used to train models and is not shared with the model providers. We're ready to deploy Mythos-class models, the latest generation of security AI, as soon as they become available.
How long does a pentest take?
The Pentest Agent delivers first results within 24 hours. A fully manual pentest report is ready within 3–7 business days.
What does a pentest cost?
A pentest starts from €2,500. The final price depends on scope and depth; you get a fixed price upfront, no surprises afterwards.
What is the difference between a pentest and a vulnerability scan?
A vulnerability scan runs automated tools and stops there. A pentest adds exploitation, proves the impact and finds chained flaws that scanners miss.
How often should you run a pentest for NIS2 compliance?
NIS2 requires regular security assessments. At minimum annually, after major changes, and ideally continuously via continuous pentesting.
Do you always find vulnerabilities?
At nearly every organization we test, we find a way in. You'll then know exactly where you're vulnerable and what to fix.
What certifications do your pentesters hold?
DEFION pentesters are certified with OSCP, OSWE, CEH and CREST. They verify the quality of every pentest.
Can DEFION also test OT and industrial environments?
Yes. DEFION offers a dedicated OT Pentest and OT Red Teaming service. We test without disrupting your production processes.
What does a DEFION pentest report contain?
Proven findings with reproduction steps, CVSS scores and a management summary. Readable for both technical and executive audiences, immediately actionable.
