Network Penetration Testing Services

Network penetration testing is a security assessment in which skilled testers simulate real-world attacks against an organization's network infrastructure to identify exploitable vulnerabilities, including misconfigurations, outdated software, weak authentication, and insufficient network segmentation. Unlike automated scanning alone, it involves manual analysis and, where appropriate, controlled exploitation to validate that identified issues represent genuine, exploitable risk.

External network penetration testing simulates an attacker with no internal access, testing internet-facing systems such as firewalls, VPNs, and exposed services for vulnerabilities that could provide an initial foothold. Internal network penetration testing assumes an attacker already has some level of access, testing how far that access could spread through lateral movement, privilege escalation, and weaknesses in internal segmentation and controls.

Vulnerability scanning uses automated tools to identify known vulnerability signatures and misconfigurations, typically producing a broad list of potential issues with a notable false positive rate. Network penetration testing goes further, using manual analysis and controlled exploitation to validate which findings are genuinely exploitable and to demonstrate real-world attack paths, such as lateral movement or privilege escalation, that scanning alone cannot identify.

Network VAPT (Vulnerability Assessment and Penetration Testing) combines vulnerability assessment, which broadly identifies potential network weaknesses using automated and manual techniques, with penetration testing, which actively attempts to exploit identified vulnerabilities to confirm real-world impact. Together, VAPT provides both breadth of coverage and depth of validation.

Best practice is at least annually, with additional testing after significant network changes, such as new infrastructure deployments, office relocations, mergers, or major configuration updates. Organizations subject to compliance requirements like PCI DSS often have specific mandated testing frequencies, typically at least annual, with additional testing after significant changes.

HashRoot conducts testing carefully to minimize disruption, with rules of engagement agreed upon before testing begins to manage risk around critical systems. Exploitation of high-risk findings, particularly those that could impact availability, is done in a controlled and coordinated manner, often with your team informed in advance for especially sensitive systems.

Yes. Active Directory and broader identity infrastructure are common targets for privilege escalation and lateral movement in real-world breaches, so HashRoot's internal network penetration testing includes assessment of Active Directory configuration, permissions, and common attack paths such as Kerberoasting and misconfigured group policies.
