External Infrastructure Penetration Testing
Senior-led external network penetration testing that maps your real internet-facing attack surface, then manually exploits it — every exposed port, service, VPN gateway and admin panel a real attacker would find first. We hand you a prioritised, evidence-backed report and a free retest to prove the perimeter actually holds.
- Full external attack-surface enumeration
- OSCE / OSCP-certified testers
- Manual exploitation — never a scan-and-send
- Free remediation retest included
Your perimeter is the one thing every attacker can already see.
Every internet-facing service, forgotten subdomain and open port is a door someone else is already testing — for free, around the clock. Automated scanners flag what's obvious; they don't chain an exposed admin panel to a weak VPN to a foothold on your internal network. A senior tester attacks your perimeter the way a real adversary does, before they get the chance.
Full coverage of your internet-facing attack surface — inside and out.
Structured around your real perimeter — every IP, port and service in scope — then extended with the OSINT and credential exposure work that separates a real external penetration test from a vulnerability scan.
-
Exposed Services & Ports
Full-range TCP/UDP enumeration and manual testing of every service reachable from the internet.
-
VPN & Remote Access
Authentication bypass, weak configuration and known CVEs in your VPN and remote-access gateways.
-
Firewall & IPS
Rule misconfigurations, filtering gaps and evasion techniques a real attacker would use to get through.
-
TLS & Certificates
Weak ciphers, expired or misissued certificates and protocol downgrade risks across every exposed endpoint.
-
Email & DNS Security
SPF, DKIM and DMARC gaps, zone transfer exposure and DNS misconfigurations that enable spoofing.
-
Web & API on the Perimeter
Internet-facing applications and APIs tested as an entry point into the wider network.
-
Credential Exposure & OSINT
Leaked credentials, breach-data exposure and open-source intelligence that shortcuts an attack.
-
Misconfiguration & Default Creds
Default passwords, unnecessary services and hardening gaps left open on internet-facing systems.
From scope to retest — a disciplined, four-phase engagement.
-
01
Scope & rules of engagement
We agree the IP ranges, domains and hosts in scope, and set safe testing windows and escalation contacts before anything starts.
-
02
OSINT & surface mapping
We enumerate the full external attack surface — hosts, ports, services and exposed credentials — the same way a real attacker would.
-
03
Exploitation of exposed services
We hand-test and safely exploit each exposed service and misconfiguration, chaining issues to prove real network access.
-
04
Report & free retest
You get a prioritised, evidence-backed report; after you remediate, we retest to confirm every exposure is closed — at no extra cost.
A report your engineers can act on — and your auditors accept.
-
Prioritised findings
Every exposure risk-rated by real network impact and ordered so you close what matters first.
-
Reproducible evidence
Step-by-step proof for each finding — the exact port, service and request — no vague, unverifiable claims.
-
Ops-ready remediation
Specific, actionable hardening guidance written for network and infrastructure teams, not a generic checklist.
-
Executive summary
A plain-language overview for leadership, boards and clients requesting assurance.
-
Free remediation retest
We re-test every exposure and confirm it's closed — included with every engagement.
-
Attestation letter
A summary letter you can share with customers, partners and auditors on request.
Evidence that maps to the frameworks you report against.
One engagement, structured so its output slots straight into the assurance work you already have to do.
| Framework | How this engagement maps |
|---|---|
| OWASP | Any web application or API discovered on the perimeter is tested against the current OWASP Top 10 and API Security Top 10. |
| PCI-DSS 11.4 | Satisfies the external network penetration-testing requirement for cardholder-data environments. |
| SOC 2 | Provides the independent external pentest evidence auditors expect for the Security trust-services criteria. |
| ISO 27001 (A.8.8 / A.8.9) | Supports the vulnerability-management and configuration-management controls in your ISMS. |
| Essential Eight (ASD) | Evidences patching and hardening maturity against internet-facing services and applications. |
What teams ask before an external test.
What's the difference between an external penetration test and a vulnerability scan?
A scan runs automated tools and lists potential issues; an external penetration test is a senior human manually exploiting exposed services and chaining them to prove real network access. We never scan-and-send.
What IP ranges or domains do you need from us?
Just the public IP ranges and/or domains you want tested. We confirm the exact scope with you before testing starts, and only test what's explicitly in scope.
Is it safe to test our production perimeter?
Yes. We work within agreed rules of engagement, avoid destructive actions by default, and coordinate any higher-risk tests — such as against fragile legacy services — with you in advance.
Do you test black-box or with credentials?
External engagements are typically black-box — no credentials, the same starting point as an internet-based attacker. We can add credentialed checks for specific exposed services on request.
How long does an external penetration test take?
Most engagements run three to five days, depending on the size of your external footprint. We confirm timing once the IP ranges and domains in scope are set.
Can we use the report for PCI-DSS, SOC 2 or client assurance?
Yes. The report and optional attestation letter are written to satisfy auditor and customer requirements across PCI-DSS 11.4, SOC 2 and ISO 27001.
Do you provide external penetration testing across Australia?
Yes. External infrastructure testing is delivered remotely Australia-wide from our Sydney base. See penetration testing across Australia for coverage, methodology and the engagement process.
