What we look for

Network vulnerabilities we hunt for

Your perimeter is the first thing an attacker sees. We probe every internet-facing system for the exposed services and misconfigurations that hand an outsider their first foothold.

Exposed Services & Ports

Internet-facing services that should never be reachable from outside.

We test for

  • Service and port discovery
  • Management interface exposure
  • Legacy and forgotten hosts
  • Default and sample content

Vulnerable & Unpatched Systems

Missing patches on perimeter systems that attackers exploit first.

We test for

  • Known-CVE exploitation
  • Outdated software and appliances
  • Insecure protocols
  • Version and banner analysis

Perimeter Authentication

Weak access controls on VPNs, portals, and mail that open the door.

We test for

  • Password spraying
  • MFA gaps and bypass
  • VPN and portal weaknesses
  • Credential reuse

Misconfiguration & Information Leakage

Configuration errors that hand an outside attacker an easy foothold.

We test for

  • TLS and SSL misconfiguration
  • Verbose errors and metadata
  • DNS and subdomain exposure
  • Cloud and CDN misconfiguration

FAQ

Frequently asked questions

What teams most often ask before scoping external network penetration testing.

Still have questions?
01What is the difference between external and internal network testing?

External testing assesses your internet-facing systems the way an outside attacker sees them, looking for the first foothold. Internal testing simulates an attacker who is already inside and tests how far they can spread. Many organizations run both for full coverage.

02What systems are in scope?

Typically your public IP ranges, VPNs, mail servers, exposed management interfaces, and other internet-facing infrastructure. We confirm the exact scope with you before testing begins.

03How long does an external network test take?

Most engagements run about one week depending on the size of your external footprint, followed by reporting and a complimentary retest.
