What Is External Penetration Testing?

External penetration testing is a security assessment that simulates real-world attacks against your internet-facing assets. Unlike internal tests, external pentests focus on what an attacker can see and exploit without any prior access to your network.

What We Test

Our external pentest methodology covers your web applications, login portals, email systems, DNS infrastructure, and any publicly exposed services. We attempt to compromise user accounts through password spraying, credential stuffing, and exploitation of authentication weaknesses.

Why It Matters

Most data breaches begin from the outside. Attackers target weak credentials, unpatched software, and misconfigured services. An external pentest reveals these vulnerabilities before real attackers do.
