Internal Network Penetration Testing
Sophisticated cybercriminals often look to circumvent your firewalls and other security controls to gain authorized internal access to critical systems and data. Cybercriminals often achieve this goal by launching targeted phishing attacks that entice employees to click a malicious link, open an infected document or lead them to the attacker’s website. Organizations must develop strong layers of internal security to mitigate the risk of these attacks.
Internal network penetration testing aims to identify security vulnerabilities that exist inside of the corporate network for enumeration and remediation. This test simulates a malicious employee (e.g., an employee that’s been phished, an employee that’s gone rogue -or- someone walking into the office and plugging in a rogue device). The primary objective of network penetration testing is to improve your network’s security resiliency.
Canary Trap has developed a robust methodology for internal network penetration testing. We simulate a real-world attack launched by a sophisticated cybercriminal on the corporate network, network devices and applications. Our elite team of security experts seek to identify holes and gaps before cybercriminals can locate and exploit them.
To meet a high standard of security, internal network penetration testing should be performed on a regular cadence. Most cyber insurers now demand that policy holders undertake an internal network penetration test annually as a condition of coverage.
Penetration testing will identify weaknesses that exist within your security model. Committing to undertake regular offensive security (penetration) testing ensures that your business can remain vigilant and resilient to new threats. Undertaking internal network penetration testing can assist with improved planning when it comes to business continuity and disaster recovery.
Canary Trap combines human expertise with sophisticated tools, proven methodologies and, where appropriate, threat intelligence to ensure a thorough, in-depth approach to security testing and assessments.

FAQs
What is an Internal Network Penetration Test?
An Internal Network Penetration Test simulates an attacker who has gained access to your internal corporate network (through phishing, malware, or insider threat). The goal is to identify vulnerabilities, misconfigurations, and weaknesses that could allow lateral movement, privilege escalation, or data exfiltration.
Why is internal penetration testing important for my organization?
Internal testing helps uncover risks that firewalls and perimeter defenses cannot prevent. It validates the effectiveness of internal security controls, identifies gaps in patch management, and ensures compliance with cyber insurance requirements and industry standards.
What systems and areas are typically tested during an internal assessment?
We assess a wide range of internal assets, including:
- Workstations and servers
- Active Directory (AD) and domain controllers
- File shares and databases
- Internal applications and services
- Network segmentation and access controls
How often should internal penetration testing be performed?
Best practice is annually or whenever significant changes occur in your IT environment (e.g., new systems, mergers, or infrastructure upgrades). Many cyber insurers now mandate annual internal penetration testing as a prerequisite for coverage.
What deliverables will Canary Trap provide after the test?
You’ll receive a comprehensive Findings Report that includes:
- Executive summary for leadership teams
- Technical findings with severity ratings
- Proof-of-concept exploits (where applicable)
- Actionable remediation guidance
- Findings review meeting with our security experts
