Breach Your Network Before Attackers Do
Your network perimeter is the first line of defense — and your internal network is where attackers pivot, escalate, and exfiltrate after gaining initial access. Our network penetration testing covers both sides: external assessments that probe internet-facing infrastructure for exploitable weaknesses, and internal tests that simulate a compromised employee or contractor to map the blast radius of a breach through your Active Directory, network segments, and critical systems.
What we test
Our testers systematically evaluate every attack vector relevant to this assessment type.
External Perimeter Testing
We probe your internet-facing attack surface — firewalls, VPN concentrators, mail servers, DNS infrastructure, web servers, and exposed services. Testing covers port scanning and service enumeration, version-specific vulnerability exploitation, SSL/TLS misconfiguration analysis, default credential discovery, and publicly accessible management interfaces that should be restricted.
Active Directory Attacks
Active Directory is the backbone of enterprise networks and a primary target for attackers. We test for Kerberoasting, AS-REP roasting, NTLM relay attacks, delegation abuse (constrained, unconstrained, resource-based), DCSync, Golden/Silver ticket attacks, GPO abuse, ACL exploitation, and AD Certificate Services (ADCS) misconfigurations that enable domain compromise.
Lateral Movement & Pivoting
Starting from a simulated foothold, we move through your network using pass-the-hash, pass-the-ticket, overpass-the-hash, WMI execution, PSRemoting, SMB lateral movement, and RDP pivoting. We map trust relationships, identify network segmentation gaps, and determine how far an attacker can reach from a single compromised workstation or server.
Privilege Escalation
We identify local and domain-level privilege escalation paths including misconfigured services, unquoted service paths, writable scheduled tasks, DLL hijacking opportunities, kernel exploits on unpatched systems, credential harvesting from memory and credential stores, and group policy preference passwords that provide a direct path to domain administrator.
Network Segmentation Validation
We verify that your network segmentation actually works by attempting to cross VLAN boundaries, bypass firewall rules between segments, access production systems from development networks, and reach sensitive environments (PCI cardholder data, HIPAA ePHI) from general corporate segments. Poor segmentation is one of the most common findings in enterprise environments.
Wireless Network Assessment
We evaluate your wireless infrastructure for WPA2/WPA3 implementation weaknesses, evil twin susceptibility, rogue access point detection gaps, client isolation enforcement, guest network segmentation, and RADIUS/802.1X configuration flaws. Wireless attacks can provide an attacker with internal network access without needing a physical connection.
Our approach
A structured methodology that ensures thorough coverage and actionable results.
Scoping & Reconnaissance
We define the engagement scope — target IP ranges, network segments, Active Directory domains, and testing restrictions. Passive and active reconnaissance identifies live hosts, open ports, running services, OS versions, domain structure, and network topology. For external tests, we also perform OSINT to discover shadow IT and forgotten infrastructure.
Vulnerability Assessment
Using Nessus Pro and supplementary scanning tools, we identify known vulnerabilities, misconfigurations, default credentials, and weak protocols across all in-scope systems. Every automated finding is manually validated to confirm exploitability and eliminate false positives. We prioritize vulnerabilities based on real-world attack utility, not just CVSS scores.
Exploitation & Post-Exploitation
We exploit confirmed vulnerabilities to gain footholds, then perform post-exploitation activities: credential harvesting, lateral movement, privilege escalation, and persistence establishment. The goal is to demonstrate realistic attack paths to your most sensitive assets — domain controllers, databases, file shares containing sensitive data, and critical business systems.
Reporting & Remediation
Our report maps every attack path with step-by-step evidence, from initial access through domain compromise. Each finding includes severity ratings, affected systems, exploitation evidence, and specific remediation guidance. We provide both quick wins for immediate risk reduction and strategic recommendations for long-term network hardening.
