Vulnerabilities can be anywhere on your network. NetSPI’s internal network penetration testing identifies security gaps, provides actionable guidance on how to improve your network security, and helps you meet compliance requirements, such as PCI DSS.

Comprehensive Internal Network Security Testing

Internal penetration testing is crucial for identifying weaknesses within an organization’s internal network. By simulating realistic attack scenarios, NetSPI’s internal network penetration testing reveals vulnerabilities like excessive user privileges, unpatched systems, and poorly secured communication channels. Our network security testing also helps to uncover misconfigurations in firewalls, routers, or security policies that could allow unauthorized access to sensitive data or critical systems.

OWASP Top 10 Coverage

What do NetSPI Internal Network Assessments test for?

NetSPI’s approach to internal network penetration testing is based on best practices, including NIST SP 800-53, PCI DSS, OWASP Top 10, and the MITRE ATT&CK framework. Common internal pentesting methodologies include privilege escalation, lateral movement, identifying weak access controls, and evaluating the effectiveness of internal security policies. The scope of our testing scales to match your internal network infrastructure, including workstations, servers, and intranet applications.
