Penetration Testing

227 InfoSec penetration testing identifies exploitable weaknesses in your networks, web applications, and APIs before an attacker can use them. Every engagement is scoped, authorized in writing, and conducted under agreed Rules of Engagement, and it goes beyond automated scanning to show how vulnerabilities can be chained together in a real-world attack.

We perform external and internal penetration tests, combining automated tooling with expert-led manual testing tailored to your environment and risk profile. Each engagement ends with a findings report and a walkthrough meeting with your team, followed by mitigation retesting to confirm your fixes work.

How an Engagement Works

Every penetration test follows the same documented process, so you know exactly what will be tested, when, and with whose permission.

  1. Scoping Call

    We learn your environment, goals, and constraints, and agree on exactly which networks, applications, APIs, and IP ranges are in scope.

  2. Rules of Engagement

    We document the testing methods, testing windows, points of contact, and any systems that are off limits before any testing begins.

  3. Authority to Conduct Letter

    Your authorized representative signs written permission for the test. No testing starts until this letter is in place.

  4. Testing

    We carry out the agreed tests within the approved scope and testing window.

  5. Findings Report

    You receive a written report with each finding, its risk, the evidence, the affected systems, and remediation guidance.

  6. Findings Report Meeting

    We walk your team through the results, answer questions, and help you prioritize remediation.

  7. Mitigation Retest

    Once you have remediated, we retest the findings to confirm your fixes are effective.

Tests your internet-facing systems from the outside, the way an attacker on the internet sees them.
