What is Internal Penetration Testing?
Network testing is a way to find and fix problems in your computer network. It looks for weaknesses that bad people might use to break in and cause trouble. This kind of testing copies what bad people might do, like if someone who works for you gets mad and wants to do bad things. It’s a good idea to do network testing once a year or after you make big changes to your network. This helps you keep up with the latest tricks and ways to break into networks. Some rules say you have to do network testing, like PCI-DSS, ISO27001, and SOC 2.
Why Conduct an Internal Pentest?
Conducting an internal penetration test provides invaluable insights into the potential security risks your organization may face from internal threats. Here is what you will gain after conducting a project with our team:
Validate your existing security controls
Our external penetration tests will help validate the effectiveness of your existing security controls in preventing and detecting external attacks. By simulating an attacker, our experts will identify gaps in your defenses and provide remediation measures to improve your ability to prevent cyberattacks.
Understand the potential impact of a cyberattack
Our internal penetration testing service will simulate real-world attack scenarios to help you understand the consequences of a successful breach. This includes the potential for data loss, system downtime, and reputational damage. By knowing the potential impact, you can prioritize remediation efforts and better protect your organization.
Identify & fix vulnerabilities in your internal network
Using a mix of automated and manual techniques, our team will identify all security vulnerabilities within your internal network, including misconfigurations, outdated software, and weak access controls. This will help you prioritize remediation efforts and reduce your overall risk exposure.
Improve internal network security posture
Comply with regulatory requirements
Many regulatory frameworks require internal penetration testing to be performed as part of their compliance requirements. Our tests will help ensure that your organization meets these requirements efficiently and avoids potential penalties for non-compliance.
When Should You Perform an Internal Penetration Test?
Knowing when to conduct internal penetration testing is essential for maintaining a strong security posture. It is highly recommended to perform internal pentests in the following situations to stay proactively prepared to handle potential threats:
- After making significant changes to the network, infrastructure or IT systems
- As part of your organization's regular security assessment routine
- When new regulations or industry standards are introduced
- In response to a security incident or data breach
- Prior to launching a new product or service that requires internal access
Common Cybersecurity Risks &
Vulnerabilities Identified
Internal penetration testing often reveals several common vulnerabilities, including:
Weak encryption protocols
Inadequate encryption can leave data transmissions susceptible to interception and unauthorized access.
Unpatched software and systems
Failing to apply security patches can leave your systems vulnerable to known exploits and attacks.
Insufficient monitoring and logging
A lack of proper monitoring and logging can make it difficult to detect and respond to potential security incidents in a timely manner.
Insecure user authentication & access controls
Weak or improperly implemented authentication mechanisms can allow unauthorized access to sensitive data and systems.
Inadequate segmentation of sensitive data
Without proper data segmentation, an attacker could potentially access multiple parts of your network, leading to increased damage.
Compromised employee accounts or devices
Attackers can use stolen credentials or infected devices to infiltrate your network and access sensitive information.
We Guide You Through Each Step of The Process
If your organization has not gone through network penetration testing before, you may not know what to expect. Even if you have, certainly, you are wondering what Vumetric’ stages of testing are. Here is a high-level breakdown of each step of our proven process:

The Main Benefits of Testing The Security of Your Internal Network
Frequently Asked Questions

The purpose is to assess the vulnerability of your internal network infrastructure to insider threats, such as employees, contractors, or partners. The test helps identify weaknesses, potential entry points, and the impact of a successful attack on your organization’s confidential information.
The process includes internal network scanning, port scanning, system fingerprinting, vulnerability identification, exploitation, manual vulnerability testing and verification, firewall and ACL testing, privilege escalation testing, password strength testing, network equipment security controls testing, and third-party/vendor security configuration testing.
Before engaging with a provider, prepare a checklist that includes your goals for the test, the number of internal workstations, servers, and internal and external IPs on your network that you wish to assess.
Our internal penetration tests are designed to minimize any potential impact on your network. The overwhelming majority of our clients never notice that any testing is being done. With that said, we take all necessary measures to prevent downtimes and work closely with your team to identify any areas that may be susceptible to causing disruption to your operations.
For an internal penetration test, the tester may require some level of authorized access to your network, such as user credentials or VPN access. This allows the tester to simulate an insider attack and identify vulnerabilities that may not be visible from an external perspective. The scope of access will be defined during the planning phase. In the event that on-site access is required, our team has built an internal pentesting device that can be shipped and deployed instead of requiring a tester in your facilities.
Internal penetration testing is a critical component of a comprehensive and mature cybersecurity strategy. It complements other security measures, such as external penetration testing, vulnerability assessments, and security awareness training, by identifying vulnerabilities within your internal network that may be exploited by an insider. Regular internal penetration tests can help you stay ahead of emerging threats, evaluate the effectiveness of your security controls, and demonstrate your commitment to maintaining a strong security posture to clients, partners, and regulators.
Our internal penetration tests helps several organizations of all types meet compliance requirements every year by identifying vulnerabilities that need remediation. Once remediation testing is completed, we provide an official attestation confirming that vulnerabilities have been remediated, helping organizations meet compliance requirements efficiently.
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.
Professional Reporting With Clear & Actionable Results
Our penetration reports deliver more than a simple export from a security tool. Each vulnerability is exploited, measured and documented by an experienced specialist to ensure you fully understand its business impact.
Each element of the report provides concise and relevant information that contributes significantly towards improving your security posture and meeting compliance requirements:
