While conventional security strategies focus on protecting network perimeters, external defenses alone won’t protect your organization from attackers who are already inside your system. Compromised employee accounts or third-party supply chain risk allow attackers to escalate privileges and move laterally inside your network, often undetected until after damage has been done.

What Is an External Network Penetration Test? | Nexoryn Systems

Nexoryn Systems — Fri, 24 Apr 2026 17:28:01 GMT

An external network penetration test (pentest) assesses your digital perimeter’s resilience to attacks such as phishing, brute-force password attacks, and SQL injection. This gives you insights into vulnerabilities that might be used by attackers who haven’t yet penetrated your perimeter. Conducting external network pentests helps you protect critical assets by securing your security perimeter before attackers get an initial foothold.
