Know where you are vulnerable.
Before attackers do.
First vulnerabilities in your environment within 24 hours. Every finding manually validated by certified ethical hackers. Breach rate: 93%.
From external scans to full red teaming: DEFION tests your entire attack surface. AI scans wide, our hackers go deep.
What is a penetration test?
A penetration test is a controlled attack simulation by certified security experts. DEFION tests networks, applications and infrastructure for vulnerabilities that real attackers would exploit. AI scans your full attack surface in hours, then our certified hackers (OSCP, OSWE) manually validate every finding. You receive a report with reproduction steps, severity ratings and concrete recommendations. First results within 24 hours.
Why organisations have specialists run their pentests
Automated scanners miss the real attack paths
Tools generate hundreds of findings but miss chained vulnerabilities and business logic flaws. The gaps surface in production. Often after an attacker found them first.
200-page pentest reports are unusable
Generic reports full of false positives. Your dev team doesn't know where to start, so they start nowhere. Real vulnerabilities stay open, drowned out by the noise.
A one-off pentest is a snapshot in time
The next release introduces new vulnerabilities. Between tests, your security posture is unknown. You only learn where you stand again when you test again. Often a year later.
Four traits that set us apart
No junior consultants, no scan-and-send reports, no false-positive padding.
Hands-on certified hackers
Senior-onlyOSCP, OSWE, CEH and CREST certified. Our pentesters have years of ethical hacking experience. Not junior consultants copying scan output into a Word template.
AI breadth + human depth
Best of bothTools cover the surface in hours; our experts find the chained flaws only humans see. Faster and deeper than either alone. First results within 24 hours.
Reproduction steps + fix suggestions
Directly actionableEvery finding includes a curl command, code patch or step-by-step reproduction. Your dev team can act immediately. No detective work to understand the issue.
93% breach rate
Proven track recordWe get in at almost every organisation we test. That's not a brag for us. It's a warning for you. And afterwards you know exactly where you're vulnerable.
13 specialised pentesting services
From external scans to OT red teaming. Every service manually executed by certified experts.
How a DEFION pentest works
We use the same tools and techniques as real attackers. We go beyond automated scanning: manual exploitation, chained vulnerabilities, realistic attack paths. No false positives from tools alone.
Reconnaissance
Passive and active discovery of all reachable systems, subdomains and services.
Manual testing
Expert-led exploitation. Finding chained attack paths that scanners miss. AI covers breadth, hackers go deep.
Reporting
Verified findings with proof-of-exploit, CVSS scores and prioritised recommendations for both technical teams and management.
