Internal Penetration Testing

Assume breach. Then see how far an insider can move.

Real attackers eventually get inside — through phishing, supply chain, or a single compromised credential. Internal pen testing simulates that foothold and measures how much damage is possible from there.

What we test

  • ▸Active Directory / identity infrastructure
  • ▸Internal network segmentation + lateral movement paths
  • ▸Privilege escalation opportunities (local + domain)
  • ▸Internal services, file shares, databases
  • ▸Endpoint detection bypass (EDR/AV evasion)
  • ▸Credential harvesting + reuse patterns

How we approach this engagement

Each phase is signed into the QSurface provenance chain in real time.

01

Foothold Setup

We start with the access level you specify — VPN credential, phishing-simulated endpoint, or direct network drop.

02

Internal Reconnaissance

Map your internal topology, identity infrastructure, and high-value assets the way an attacker would.

03

Lateral Movement & Privilege Escalation

Demonstrate the actual blast radius of the assumed compromise.

04

Reporting & Remediation

Detailed attack-path narrative + QSurface chain + prioritized remediation plan.

What you receive

  • ✓Attack-path narrative (how we got from A to crown jewels)
  • ✓Technical findings with EDR/SIEM detection gaps noted
  • ✓QSurface provenance chain
  • ✓Identity + segmentation hardening recommendations
  • ✓Free retest within 90 days

Why TLN

  • ★We chain identity + network + endpoint findings into a single attack story
  • ★Your blue team gets actionable detection-engineering input
  • ★AI-augmented coverage of large internal estates
  • ★QSurface chain proves exactly what we touched
