External Penetration Testing Services

Unlike internal pen testing, this engagement starts entirely from outside your network, with nothing but what's public. Before any active testing begins, we collect your target IP ranges, domains, and ASN data, then run passive OSINT: subdomain enumeration, Shodan and Censys scans, DNS reconnaissance, and checks for leaked credentials.

At this stage, we also agree on the testing model: black-box, where testers start with zero knowledge and simulate a full external attacker, or grey-box, where partial information speeds up coverage for a compliance-driven engagement.

Which model fits often comes down to your threat modeling priorities. Before a single test runs, we also lock in the scope document, the rules of engagement, which internet-facing systems are in play, any out-of-scope systems, and emergency escalation contacts.

This is where reconnaissance turns into evidence. Asset discovery starts with active port scanning, service fingerprinting, and technology stack identification, and it's also where forgotten or shadow assets nobody remembered were still live tend to surface.

From there, vulnerability identification matches each discovered service version against known CVEs, checks for misconfigurations and weak authentication, and flags exposed admin panels and unpatched services that automated security tools alone tend to miss.

Exploitation comes next: we manually exploit each finding to prove practical impact, whether that means reaching sensitive data or gaining a foothold, and what it means for your business. To test what an attacker can reach once inside, we apply network penetration testing.

Finally, attack chain analysis ties individual vulnerabilities into a real exploit path, from initial access through privilege escalation to potential lateral movement risk into your internal networks. This is what a vulnerability scanner cannot show you.

You get three deliverables from every engagement, plus a live walkthrough. The executive summary is written for your CISO and C-level in plain language: the attack path narrative, a business risk summary, and the top remediation priorities, including what's at stake if an attacker reached your internal assets through this path.

The technical report covers per-asset findings with CVSSv3 severity ratings (Critical, High, Moderate, or Low), proof-of-concept evidence, affected service details, and a remediation guide your developers can act on directly. The letter of attestation gives auditors, compliance reviewers, and enterprise partners the third-party proof they need that the test happened.

Then we debrief live: the tester who ran the engagement walks your security and engineering teams through the findings, explains each attack chain, and answers questions in real time.

Once you've closed the findings, we re-test to confirm each fix holds, rather than just moving the same exposure one step closer to your internal systems. Re-testing is included as part of the engagement: we stay with you through remediation until every finding is verified closed.
