EXT-01 // EXTERNAL PENETRATION TESTING

External Penetration Testing

Attack your perimeter the way the internet does.

// 01 · Mission Profile

We assault your internet-facing assets the way a real attacker would: domains, VPNs, mail servers, cloud edges and the forgotten subdomains nobody remembers. Then we hand you a clear path to lock every door we opened.

What you get out of it

  • Know exactly what an outside attacker can reach
  • Close exposed services before they're abused
  • Validate your perimeter defenses with real exploitation

Representative findings

[CRIT]Remote code execution via outdated component
[HIGH]Broken access control on privileged endpoints
[MED]Missing security headers & weak TLS configuration
[LOW]Information disclosure in verbose error responses

// representative severities · your real findings come with proof & remediation

Flight plan

  1. 01

    Scope & Recon

    We align on goals, rules of engagement and crown jewels, then map your real attack surface the way an adversary would.

  2. 02

    Attack & Exploit

    Hands-on, manual exploitation using the same tools and techniques as real threat actors, not just an automated scan.

  3. 03

    Escalate & Pivot

    We chain weaknesses, escalate privileges and move laterally to prove genuine business impact, not hypothetical risk.

  4. 04

    Report & Remediate

    Clear, prioritized findings with proof, a remediation roadmap, and a free retest to confirm the fixes hold.
