Network and infrastructure penetration testing.

We assess external internet-facing perimeters and internal corporate networks, testing routers, switches, firewalls, VPN gateways, and VLAN segmentation to identify exploitable network paths.

Network and Infrastructure Penetration Testing Architecture

What is in scope

Key technical areas and vulnerability classes evaluated during the assessment.

External perimeter assessment

Testing public IP ranges, exposed management interfaces, border routers, firewalls, and VPN gateways for exploitable services and weak authentication.

Internal network and VLAN segmentation

Testing whether traffic can cross between user networks, guest Wi-Fi, and restricted production or cardholder data subnets.

Network device configuration audit

Evaluating Cisco, Juniper, Palo Alto, Fortinet, and core switch configurations for default credentials, insecure SNMP, and management plane exposure.

Name resolution and spoofing attacks

Testing internal segments for LLMNR, NBT-NS, mDNS poisoning, ARP spoofing, and SMB relay exposures.

VPN and remote access security

Testing IPsec and SSL VPN concentrators for cipher weaknesses, split-tunneling risks, and multi-factor authentication bypasses.

Lateral movement path analysis

Evaluating how an attacker with a foothold on a single workstation or subnet could pivot to critical internal infrastructure.

Testing methodology

Our step-by-step engineering workflow from reconnaissance to verified proof of concept.

1. Host discovery and service enumeration

We identify live hosts, open TCP/UDP ports, running service versions, and exposed network protocols across in-scope subnets.

2. Vulnerability assessment and configuration review

We correlate service banners and device configurations against known CVEs and NIST/CIS network security baselines.

3. Controlled manual exploitation

Our engineers validate exploitable services, test segmentation rules, and demonstrate realistic pivot paths without disrupting network stability.

4. Firewall and network retest

We re-scan and re-verify network segments after firewall rules, ACLs, and patches are applied.
