Internal Penetration Testing Services

Assess your organisation’s internal networks, servers, and workstations to identify vulnerabilities that could be exploited by inside threats.

Our UK-based team of certified ethical hackers use a combination of automated tools and manual techniques to simulate real-world attacks on your internal networks to identify and exploit vulnerabilities.

What Our Internal Testing Includes

Internal penetration testing involves an assessment of your organisation’s internal networks, servers, and workstations. This type of testing is crucial for identifying vulnerabilities that could be exploited by attackers who have already gained access to your internal network, whether through phishing, social engineering, or other means.

Firewall and Network Device Testing

We assess the security of your firewalls, routers, switches, and other network devices to identify misconfigurations and vulnerabilities.

This includes testing for weak access controls, outdated firmware, and common misconfigurations that could be exploited by attackers.

Server and Workstation Testing

We conduct thorough assessments of your servers and workstations to identify vulnerabilities such as unpatched software, weak passwords, and insecure configurations.

Our team will simulate real-world attacks to uncover potential entry points that could be exploited by malicious actors.

Exploitation and Lateral Movement

We attempt to exploit discovered vulnerabilities to validate their existence and assess the real-world impact.

Through this we create an attack chain that can highlight the route to compromise. We continue our chain of attack by attempting to move laterally through the network.

Privilege Escalation

Our testing simulates real-world attack scenarios in your infrastructure, allowing us to determine if an attacker could gain higher-level access after initial compromise.

This includes testing for lateral movement through misconfigured permissions, weak access controls, and other vulnerabilities that could allow an attacker to escalate their privileges.

Active Directory Testing

We evaluate the security of your Active Directory environment to identify vulnerabilities that could be exploited by attackers.

This includes testing for weak group policies, misconfigured permissions, and other common issues that could lead to privilege escalation and lateral movement within your network.

Network Segmentation Testing

We assess the effectiveness of your network segmentation to determine if it adequately limits access between different parts of your network.

This includes testing for misconfigurations and vulnerabilities that could allow an attacker to move laterally within your network.

Password Cracking & Auditing

We perform password cracking and auditing to identify weak passwords and poor password practices within your organisation.

This includes testing password strength, identifying reused passwords, and providing recommendations for improving your password policies.

Detailed Reporting

We provide detailed executive and technical reports that include a summary of findings, technical details, and actionable recommendations for remediation.

Our reports are tailored to both technical and non-technical stakeholders, ensuring clarity and understanding.
