External Network Penetration Testing

Identify exposed vulnerabilities from an external attacker’s perspective

Your external infrastructure is the first point of contact for attackers. Any internet-facing system, service, or misconfiguration can be discovered and targeted without prior access.

This service evaluates your external attack surface to identify vulnerabilities that could allow unauthorized access, service disruption, or data exposure.


What This Service Covers

An external network penetration test simulates a real-world attacker operating from outside your organization. The goal is to identify weaknesses that are accessible over the internet and determine how they could be exploited.

This includes:

  • Discovery of internet-facing assets and services
  • Port scanning and service enumeration
  • Identification of outdated or vulnerable software
  • Misconfigurations in exposed systems
  • Weak authentication mechanisms
  • Exposure of sensitive services or data

Internet-Facing Services and Protocols

External environments often rely on publicly accessible services that must be properly secured. These services are a common entry point for attackers if misconfigured or outdated.

Testing may include:

  • Web servers and associated services (HTTP/HTTPS)
  • Remote access services such as VPN, RDP, or SSH
  • Email infrastructure and related services
  • DNS configurations and exposure
  • FTP and file transfer services
  • Cloud-hosted endpoints and publicly accessible resources

Each service is evaluated for known vulnerabilities, misconfigurations, and potential exploitation paths.


Attack Surface Analysis

Understanding what is exposed to the internet is a critical part of security. Many organizations are unaware of all externally accessible assets.

This assessment helps identify:

  • Unknown or forgotten exposed systems
  • Shadow IT or misconfigured services
  • Unnecessary open ports and services
  • Inconsistent security controls across environments

Who This Is For

This service is ideal for organizations that:

  • Have internet-facing systems or applications
  • Provide remote access to employees or customers
  • Want to understand their exposure to external threats
  • Need to validate perimeter security controls

What You Will Receive

After the engagement, you will receive:

  • A detailed report of externally exploitable vulnerabilities
  • Clear explanation of risk and potential impact
  • Prioritized remediation recommendations
  • Insight into your organization’s external attack surface

Why This Matters

Attackers typically begin with what they can see from the outside. Even a single exposed vulnerability can lead to initial access and further compromise.

Regular testing ensures that your external systems are not unintentionally exposing your organization to risk.


Get Started

If your systems are accessible from the internet, this assessment helps ensure they are not an easy entry point for attackers.
