Your perimeter has already been crossed by someone, somewhere. We operate from inside your network — mapping every path from a compromised workstation to your crown jewels.
Modern breach statistics are unambiguous: attackers dwell inside networks for weeks before detection. The question is no longer whether someone gets in — it's how far they can travel once they do. Internal network penetration testing answers that question with evidence, not assumptions.
Privilege Zero operates from an agreed starting position — a standard domain workstation, VPN access, or VLAN membership — and methodically attacks internal hosts, authentication infrastructure, and network devices to demonstrate true lateral movement potential.
We don't stop at "we found open SMB". We chain vulnerabilities into complete attack paths and show your board exactly what a determined adversary would reach from a single compromised laptop.
Define in-scope subnets, agreed starting access (standard user, workstation, VPN), and crown-jewel targets. Establish a remote access channel mirroring the assumed breach vector — no privileged starting position unless specifically requested.
Sweep in-scope segments for live hosts, open ports, and service versions using traffic patterns calibrated to avoid IDS threshold alerts — replicating how a real attacker avoids detection during reconnaissance.
Deploy LLMNR/NBT-NS poisoning, SMB relay, and IPv6 misconfiguration attacks to capture and relay NTLM credentials — demonstrating how quickly a network-layer foothold becomes domain access.
Exploit confirmed vulnerabilities across all in-scope services — unpatched CVEs, default credentials on management interfaces, misconfigured network devices — chaining each to extend reach across segments.
Escalate from standard user through local administrator to domain administrator using misconfigured services, Kerberos attacks, credential harvesting, and Active Directory exploitation — documenting every step.
Demonstrate access to crown-jewel targets (domain controllers, database servers, backup infrastructure) through documented evidence. Remove all tooling, persistence mechanisms, and artefacts before disengaging.
BloodHound-generated graphs showing every path from your starting position to domain admin — not a list of vulnerabilities, but a map of what an attacker actually does with them.
Routers, switches, and firewalls get assessed for management interface exposure, weak credentials, and firmware-level vulnerabilities — not just servers and workstations.
We record which attacks generated alerts and which didn't — giving your SOC a prioritised list of detection gaps that reflect actual attacker behaviour in your environment.
We test whether your VLANs actually contain lateral movement — or whether a workstation on the guest network can reach your production databases.
Step-by-step walkthrough of the highest-impact attack path executed, from initial access to domain compromise — written for executive and technical audiences.
Exported attack path graphs with annotated screenshots showing every pivot point from workstation to crown-jewel target.
Per-finding documentation with CVSS scores, reproduction steps, and network-topology-aware remediation recommendations.
Annotated network map highlighting exploited pivot paths and recommended firewall rule and VLAN configuration changes.
Optional 2-hour workshop with your IT security team to walk through findings and prioritise remediation effort.
We scope from a single assumed-breach starting position and deliver full chain documentation within 10 business days.
