Service description

What Network Penetration Testing covers

External attack surface analysis and internal lateral movement validation.

Network Penetration Testing evaluates the security of an organization’s network by identifying exposed systems, open ports, and running services that could be exploited by an attacker. The objective is to identify vulnerabilities and misconfigurations in network-accessible services and determine whether they can be leveraged to gain unauthorized access. Testing is conducted in alignment with PTES and NIST SP 800-115.

External Network Penetration Testing focuses on internet-facing assets by enumerating hosts, open ports, and exposed services, and assessing them for known vulnerabilities, weak authentication mechanisms, outdated software, and insecure configurations. Discovery and validation commonly use tools such as Nmap, Masscan, Nuclei, along with manual exploitation techniques where applicable.

Internal Network Penetration Testing assumes access to a system within the internal network, such as a workstation or VPN-connected host. From this position, internal IP ranges and subnets are scanned using tools such as Nmap or RustScan to identify vulnerable services and systems. Testing includes service enumeration, credential abuse, and Active Directory enumeration using tools such as BloodHound, CrackMapExec, and Impacket, with manual verification of privilege escalation and lateral movement where applicable.

Flowchart

Our network penetration testing process

A systematic approach from reconnaissance to domain compromise.

Engagement stages

Validating risk through controlled exploitation, lateral movement, and full domain compromise.

Step 01

Reconnaissance & Network Mapping

Identify live hosts, discover subnets, and map the external and internal attack surface so we understand exactly what an attacker can see.

Step 02

Service Enumeration & Exploitation

Enumerate exposed services, identify vulnerable versions and misconfigurations, and safely validate exploitability using real-world attacker techniques.

Step 03

Vulnerability Assessment & Analysis

Deep-dive analysis of discovered issues to differentiate between theoretical risks and truly exploitable security gaps.

Step 04

Post-Exploitation & Credential Harvesting

Perform safe post-exploitation on compromised hosts to retrieve credentials, session tokens, and sensitive cached information.

Step 05

Lateral Movement & Expansion

Pivot between network segments and systems to demonstrate the impact of weak internal trust and lack of network segmentation.

Step 06

Actions on Objectives

Target key infrastructure and business-critical systems to demonstrate realistic impact without disrupting production operations.

Step 07

Domain & Identity Abuse

Abuse domain trust, group memberships, and identity paths to simulate attacker persistence and privilege abuse across the environment.

Step 08

Attack Chain Analysis & Reporting

Document full attack chains end-to-end and translate them into prioritized remediation guidance for network and security teams.
