External Network Penetration Testing

Every attacker on the internet sees the same IP addresses and domains you do. An external test checks whether that view opens a door you don't know about.

Forgotten test servers, admin panels left with default passwords, unpatched VPN appliances and misconfigured cloud services are still among the most common ways in.

We start with passive reconnaissance to map your assets, then actively test services within the agreed scope. We never touch systems outside that scope.

What we test

  • Domains, subdomains and DNS configuration
  • Open ports and services; version and configuration analysis
  • VPN, remote desktop and other remote access points
  • Email security: SPF, DKIM, DMARC
  • TLS/SSL configuration and certificates
  • External exposure of cloud storage and management interfaces

How we work

  1. Passive reconnaissance

    We identify your internet-facing assets using open-source intelligence and certificate transparency logs.

  2. Service analysis

    We scan approved IP addresses and domains for ports and services and review versions and configurations.

  3. Verification and exploitation

    We verify findings manually and demonstrate their impact in a controlled manner.

  4. Reporting

    You receive an asset inventory, the findings and prioritised hardening advice.

What you receive

  • Inventory of internet-facing assets
  • Executive summary
  • Technical findings scored with CVSS v4.0
  • Hardening and remediation advice

A good fit for

  • Businesses with remote teams
  • SMEs hosting their own servers
  • Ahead of cyber insurance or customer audits

Frequently asked questions

We don't know our IP addresses. Is that a problem?

No. We present the assets we find during reconnaissance, and we confirm the scope with you before any active testing.

Do we need permission from our hosting provider?

Some cloud and hosting providers have testing policies. We check any required notifications together during scoping.
