Services overview

What is Internal Penetration Testing?

Unlike external penetration tests, internal pen testing offers an insider’s perspective. It focuses on what could happen if someone with internal access, such as employees or contractors, tries to exploit vulnerabilities within your organization.

Leveraging tailored strategies, our seasoned cybersecurity experts simulate insider cyber-attacks to identify vulnerabilities in your internal networks, and mission critical systems. This isn’t a checkbox exercise; it’s a rigorous, custom analysis designed to root out vulnerabilities that generic testing might overlook. The goal is to provide a thorough security analysis that uncovers potential internal risk. This enables us to deliver actionable mitigation strategies that will security your internal IT environment against costly cyberattacks such as ransomwarets.


Why Should You Perform an Internal Penetration Test?

  • Ransomware Resilience
    Internal systems are prime hunting grounds for ransomware attacks, which can paralyze business operations and compromise critical data.
  • Insider Threat Landscape
    Standard security controls often neglect the risks originating from inside the organization, leaving vulnerabilities in internal defenses.
  • Growing Internal Complexity
    The growing interconnectedness of devices and systems compounds the complexity of managing internal vulnerabilities, making a thorough assessment ever more crucial.
  • Compliance Challenges
    Stringent industry regulations increasingly require internal assessments to safeguard data integrity and ensure compliance.
  • Security Solutions Shortcomings
    While conventional security tools may catch routine threats, they are often ill-equipped to defend against sophisticated internal cyberattacks.

Industry best practices recommend conducting internal pen tests at least annually to stay ahead of emerging cybersecurity threats. Additional internal testing is especially important in certain situations, such as before deploying new internal systems, after significant changes to the network, before compliance audits, after security incidents, and before significant business events such as mergers and acquisitions. This ensures that your internal network remains resilient to evolving cyber threats.

Our internal penetration testing helps a wide range of organizations meet their compliance goals each year by identifying critical vulnerabilities that require immediate remediation and efficiently meeting compliance standards such as SOC2, ISO27001, PCI-DSS.

The cost of an internal pen test varies greatly depending on the scope of the assessment.One of the key factors affecting the cost is the number of internal systems and endpoints that need to be evaluated.

Our certified penetration testers use globally recognized frameworks, such as the MITRE ATT&CK and OSSTMM testing methodologies, to provide an accurate snapshot of your current external cybersecurity risks that could escalate into an incident.Using a blend of manual and automated techniques, we not only identify vulnerabilities, we contextualize them.This helps our clients effectively allocate their IT and network security resources to protect sensitive data.

Internal pentesting is conducted from within the organization’s network by a tester who has access to the internal network. External pentesting is conducted from outside the organization’s network and simulates an attack on public-facing systems. The primary difference is the point of origin of the test, with internal testing being more focused on internal network security measures while external testing focuses on identifying vulnerabilities in systems that are accessible from the internet.
