Offensive Security
Offensive Security
Think like an attacker. Explain it like an engineer.
We test the environments your business actually depends on: web apps, cloud, identities, networks and the people around them.
500+ pentests delivered
CREST / CTPAS certified
Free retest included

Simulated pentest output — actual engagement results
>The scenario
Your cloud migration is complete. The board signed off. Six months later, an external researcher reports a critical misconfigured S3 bucket - 2.3 million customer records exposed. The CISO calls you.
Most vulnerabilities aren't found by internal teams. Our pentesters find what scanners miss - because they built the systems they now break.
Average: 14 critical findings per engagement
Offensive services with engineering depth
From scoped pentests to long-running red team work. Clear findings, realistic attack paths and remediation you can actually execute.
> Attack methodology
Based on MITRE ATT&CK framework and real-world adversary tradecraft

> Our attack philosophy
We don't just run scanners - we think like the adversary. Our engineers built the systems they now break.
$ Attackers who build
Our pentesters built enterprise infrastructure before they learned to break it.
→ HP-UX 11.31 PA-RISC to modern K8s - we've secured and broken it all
$ Manual over automated
Scanners find CVEs. We find business logic flaws, chained exploits, and zero-days.
→ 72% of our critical findings come from manual testing, not tools
$ Real impact, not PDF theater
We demonstrate actual exploitation - data exfiltration, lateral movement, persistence.
→ Board-ready impact reports, not 200-page scanner outputs
$ Reports that land
No 200-page scanner dumps. Board-ready reports with risk matrix, business impact, and concrete remediation steps.
→ Your CISO gets an executive summary, your IT team gets the technical deep-dive

“I know (unfortunately) how attackers look at systems. Today I use that knowledge to make organisations more resilient, secure, and trustworthy.”
Acknowledged by Microsoft MSRC, CERT-EU and IBD. A unique background that I bring to every engagement - to defend you.
Read the full story“We hired Neo Security expecting a standard pentest report. Instead, they demonstrated a complete attack chain - from initial access through our VPN to domain admin in under 4 hours. The board presentation wasn't a list of CVEs, it was a live demo of what an attacker could do with our data. That changed everything.”
