External Network Penetration Testing

Testing of your internet-facing hosts, services, VPNs and perimeter controls, exactly where an outside attacker begins. We confirm what an unauthenticated adversary can actually reach and exploit from the public internet.

How it works

From exposed perimeter to proven path

We build the attacker's external picture, prove what is genuinely exploitable, and hand you a prioritised fix list.

01

Attack Surface Discovery and OSINT

You cannot defend what you do not know you expose. Forgotten subdomains, staging sites, exposed admin panels and leaked credentials are where most external breaches begin.

Our methodology

We map your full internet-facing footprint, external and third-party, using OSINT, DNS and certificate analysis and breach-data review, so testing starts from the same picture a real attacker would build before touching a single service.

  • OSINT
  • Subdomain discovery
  • Exposure mapping
02

Service and Configuration Testing

Every exposed port, VPN, mail server and web service is a potential door. Weak configurations and unpatched software are the most common way in.

Our methodology

We enumerate exposed services, fingerprint versions and probe for weak configurations, default credentials and known vulnerabilities, then confirm what is genuinely exploitable rather than reporting raw scanner output.

  • Service enumeration
  • Misconfiguration
  • Patch gaps
03

Exploitation and Proven Impact

A list of theoretical issues does not tell you your real risk. You need to know what an unauthenticated attacker can actually reach and do.

Our methodology

We safely chain exploitable findings into a proven path to impact, aligned to PTES and NIST SP 800-115, and every finding is verified by hand with reproducible evidence before it reaches you.

  • Exploitation
  • PTES
  • NIST SP 800-115
04

Prioritised, Actionable Reporting

A perimeter finding is only useful if your team can fix it quickly and prove it is closed.

Our methodology

You get a prioritised report mapped to business impact with reproducible steps and clear remediation, plus a retest to confirm the fix holds.

  • Prioritised
  • Reproducible
  • Retest
FAQ

External Network Penetration Testing FAQs

What is external network penetration testing?

It is a controlled assessment of your internet-facing attack surface, hosts, services, VPNs, mail and web servers and perimeter controls, from the position of an unauthenticated attacker on the public internet. It confirms what an outsider can actually reach and exploit, not just what a scanner flags.

How is it different from a vulnerability scan?

A scan lists potential issues from signatures. An external penetration test verifies which are genuinely exploitable, safely chains them into a real path to impact, and removes the false positives, so your team spends time on risk that matters.

Do you need credentials or access to run it?

No. External testing is deliberately unauthenticated, mirroring an outside attacker. We only need your in-scope targets and rules of engagement. Authenticated and internal perspectives are covered by internal network and application testing.

What standards do you follow?

Work is aligned to PTES and NIST SP 800-115, with findings mapped to business impact and, where relevant, CVE references. Reporting supports Essential Eight, ISO 27001 and similar obligations.

Is our data kept private?

Yes. Findings are isolated to your organisation and handled in access-limited environments we control in Australia. Nothing is pooled, sold or fed into public models.
