External Network Penetration Testing

‘”top attacks before they start—test your perimeter like a hacker would.”

Your organization’s external-facing systems are the first thing attackers see—and often the easiest to exploit. External Network Penetration Testing from Patron Cyber Security identifies vulnerabilities across your internet-accessible assets, including firewalls, VPNs, mail servers, and cloud interfaces.

We simulate real-world adversaries to expose risks before cybercriminals do.

Why It Matters

Even one misconfigured server or unpatched endpoint can become an entry point to your entire network. External network pentesting helps you:

Proactively identify exploitable vulnerabilities
Prevent unauthorized access and data breaches
Meet compliance requirements (HIPAA, PCI-DSS, NIST, ISO 27001)
Understand your true exposure from an attacker’s perspective

What We Test

Our assessments include but are not limited to:

Public-facing IPs and domains
Open ports, exposed services, and APIs
DNS, SMTP, FTP, RDP, and web servers
VPNs, firewalls, and perimeter defenses
Cloud-hosted services (Azure, AWS, GCP)
SSL/TLS configurations and certificate hygiene
Vulnerability scanning & manual validation
Exploitation attempts using publicly known CVEs

Tools & Techniques

We use a blend of commercial and open-source tools combined with manual testing to ensure thorough results:

Nmap, Masscan, Nessus, Burp Suite, Hydra
Metasploit, Nikto, Gobuster, SSLyze
DNS zone transfers, subdomain enumeration, and brute forcing
Real-world exploit chains to simulate adversarial behavior

Deliverables

Our report provides clear, actionable findings:
