0x3 Security — Built by H4CK3RS. Not suits.

Offensive security built by operators, not suits. Penetration testing, red team operations, physical security, and 24/7 managed defense for small and mid-sized businesses — Arlington, TX.

Most "cybersecurity" is sold by people who've never popped a shell. We're the opposite: we think and operate like the adversary so SMBs don't have to. Every engagement is real tradecraft, mapped to MITRE ATT&CK, delivered with proof-of-concept — not a 200-page PDF you'll never read.

On this channel we show the work: sanitized engagement breakdowns, real attacker tradecraft, and how businesses actually get breached — plus straight-up guidance for anyone breaking into offensive security.

Led by Paul Nieto III — 22+ years across offensive and physical security. Receipts, not résumés: OSCP · CRTO · CRTP · CPTS · PNPT · CBBH · CDSA.
