Network pentest

Network penetration testing

We test your network the way an attacker would: from the internet-facing perimeter, from an assumed foothold inside, and across segmentation boundaries. Following PTES and NIST SP 800-115, a pentest confirms that a weakness can be exploited instead of only scanning for it.

Scope

Three perspectives

A penetration test confirms that a weakness can be exploited, not only that a vulnerability is present (NIST SP 800-115). We cover the external perimeter and the internal network from an assumed foothold. Just as important, we test segmentation by trying to cross it instead of only scanning it.

Typical scope
  • External perimeter: internet-facing services, exposed assets and remote access
  • Internal network: lateral movement, privilege escalation and Active Directory attacks
  • Segmentation: actively attempting to reach the sensitive zone (CDE) from outside it
  • Misconfigurations, weak services and credential weaknesses
  • Insufficient input validation and exploitable service vulnerabilities
  • Exploitation chained to demonstrate real, prioritised impact
How we work

A standards-based engagement

We follow the NIST SP 800-115 phases, where the attack phase loops back to discovery as new access is gained, and structure the engagement per PTES. Box type (black-, grey- or white-box) is agreed with you up front.

  1. 1

    Planning

    We agree scope, the threat model, targets and rules of engagement, and sign an NDA before any access.

  2. 2

    Discovery

    We enumerate hosts, services and trust relationships to build an accurate picture of the attack surface.

  3. 3

    Attack

    We confirm weaknesses by exploiting them, and go back to discovery whenever new access opens new paths.

  4. 4

    Segmentation validation

    We actively attempt to cross isolation boundaries into the sensitive zone, rather than relying on a scan.

  5. 5

    Reporting & free re-test

    You get a prioritised report including segmentation results; we re-test fixed issues at no extra charge, within the window set in the Statement of Work.

Deliverables

What you receive

A report structured along the lines of the PCI SSC penetration-testing report outline, with a dedicated segmentation section and the depth of our sample report.

What you get
  • Executive summary, statement of scope (CDE vs non-CDE) and methodology
  • Testing narrative and a dedicated segmentation-test results section
  • Each finding: exploitability, evidence, steps to reproduce and remediation
  • Severity scored with CVSS 3.1 and translated into business risk
  • References to CVE and CWE, plus tools used and a cleanup statement
  • Free re-test of remediated issues, within the window set in the SoW; optional confirmation letter (not a QSA attestation)
Methodology & standards

Grounded in PTES, NIST SP 800-115 & PCI guidance

PTESNIST SP 800-115PCI DSS Req 11.4CVSS 3.1CVECWE

External, internal and segmentation testing follows PTES and NIST SP 800-115. Segmentation testing checks isolation in practice and supports your PCI DSS Req 11.4 penetration-testing requirements. We provide readiness and testing; we are not a QSA and do not issue certifications. We can provide a confirmation letter, which is explicitly not a QSA attestation. Findings are scored with CVSS 3.1.

Tell us about your perimeter, your internal environment and any segmentation you rely on. We'll scope the engagement, agree the rules with you and deliver the report under NDA. The first consultation is free.
