// Test Your Defenses Before Attackers Do
Internal & External Penetration Testing
Penetration Testing, often called pen-testing, is a controlled and authorized attempt to identify weaknesses in your systems by simulating real-world cyberattacks. Internal and External Penetration Testing serve different but equally important purposes, and understanding both provides a complete picture of your security posture.
At 4Leet, we perform professional penetration testing to help businesses uncover vulnerabilities, validate existing security controls, and reduce the risk of successful attacks. Our testing reveals how attackers could gain access, what damage they could cause, and how to strengthen defenses before an incident occurs.
External Penetration Testing
External penetration testing simulates an attack from outside your organization. This method evaluates how exposed your public-facing systems are to threats such as hackers, automated bots, and cybercriminals scanning the internet for vulnerabilities.
External testing focuses on assets like web applications, email systems, VPNs, firewalls, and exposed servers. Techniques may include identifying misconfigurations, exploiting vulnerable services, or testing how easily users could be tricked into granting access. The goal is to determine whether an attacker without internal access could breach your network.
Internal Penetration Testing
Internal penetration testing simulates an attacker who already has access to your environment — such as a compromised user account, malicious insider, or stolen device. This type of testing evaluates how much damage could be done once initial defenses are bypassed.
Because internal attackers may already understand your network layout, permissions, and systems, internal penetration testing often reveals deeper risks. It helps identify excessive access privileges, weak segmentation, lateral movement opportunities, and the potential for data theft or system disruption from within.
Accurate, Actionable Results
The combined results of internal and external penetration testing provide a realistic assessment of your organization’s security. You receive detailed findings that highlight vulnerabilities, explain their impact, and outline clear steps to remediate weaknesses. While no system can be made completely invulnerable, proper penetration testing significantly reduces the likelihood and impact of successful attacks.
