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.
Foothold Setup
We start with the access level you specify — VPN credential, phishing-simulated endpoint, or direct network drop.
Internal Reconnaissance
Map your internal topology, identity infrastructure, and high-value assets the way an attacker would.
Lateral Movement & Privilege Escalation
Demonstrate the actual blast radius of the assumed compromise.
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
