External Penetration Testing

Horizon Security Solutions conducts external penetration tests to identify vulnerabilities exposed to the internet before threat actors can exploit them. Our assessments evaluate your public-facing infrastructure and provide actionable remediation guidance.

What Is External Penetration Testing?

External penetration testing evaluates your organization's internet-facing assets from the perspective of an attacker with no prior access. These engagements help identify weaknesses in systems exposed to the public internet, including web servers, VPNs, firewalls, cloud services, and remote access infrastructure.

By simulating real-world attack scenarios, organizations gain visibility into how an external adversary could compromise systems and establish an initial foothold.

Our External Penetration Tests Include

  • External attack surface enumeration

  • Service and port identification

  • DNS and subdomain discovery

  • Firewall and VPN assessment

  • Vulnerability validation

  • Exploitation of identified weaknesses

  • Cloud exposure analysis

  • SSL/TLS configuration review

  • Public asset inventory validation

  • Identification of sensitive data exposure
