What is Internal Penetration Testing?

Internal penetration testing is a type of network penetration test designed to identify and fix vulnerabilities within internal network infrastructures by replicating the same techniques used by malicious business partners or disgruntled employees attempting to breach your network from within. It is highly recommended to conduct an internal pentest at least once a year or following any major changes to the infrastructure to stay on top of the latest hacking methods. Conducting this is also required by various standards, such as PCI-DSS, ISO27001, and SOC 2.

What We Test in Your Internal Network

Organizations generally focus most of their efforts on securing their external networks, leaving their internal cybersecurity vulnerable to various threats. In order to maximize the identified vulnerabilities, our Internal penetration test focus on, but is not limited to the following:

Test Your Internal Network Remotely

Traditionally, Internal penetration testing specialists had to test your internal network directly on-site, requiring user access forms or visitor badges, which generates additional costs and approval times. Our experts have designed a remote testing device capable of testing any kind of internal network pentest while eliminating the need to be on-site.

Frequently Asked Questions

Penetration testing is essential to any business, but it remains a complex subject and choosing the right provider can be challenging. The following FAQ answers the most frequently asked questions to help you make an informed decision. Couldn’t find your answer? Ask an expert for free.

Typically, providers often require presence on-site to gain access and test your internal network.

This is not the case for us. The vast majority of our internal penetration testing projects are performed remotely. We provide various remote access options depending on testing scope and existing infrastructure, such as the Vumetric Teleporter that can be deployed anywhere around the world, or VPN solutions that leverage existing technologies, allowing us to perform any kind of internal testing remotely.

Internal penetration testing is conducted within an organization’s network and focuses on internal assets, while external penetration testing assesses the security of an organization’s external-facing systems, such as the network on which their public website is hosted. External penetration testing is generally considered to be more effective in preventing cyberattacks because it provides a more realistic assessment of how attackers would view and attack your system. Additionally, external testers are less likely to have inside knowledge of your system that could be used to exploit vulnerabilities.

Internal penetration testing is generally conducted by organizations with a well-developed and mature cybersecurity strategy or with specific compliance requirements, such as the card-processing standard PCI-DSS, which requires a yearly internal test to be conducted.

The cost of a penetration test varies significantly according to a number of factors. The most determining factor is the size and complexity of the testing scope. Contact sales to get a quote or read our blog post to learn more.

Average projects take between 2-3 weeks from start to finish.

We are flexible and usually can adapt to your deadlines.
Contact us to discuss planning and schedule.

Yes. At the end of the project, we offer a free retest of the identified vulnerabilities to validate your corrective measures.

Once this is done, we provide an attestation letter that allows your organization to easily comply with various third-party requirements (SOC 2, PCI-DSS, ISO27001, GDPR, etc.)
