Penetration Testing

External & Internal Penetration Testing

Comprehensive infrastructure testing to identify exploitable vulnerabilities across internal and external assets.

Overview

What you get with External & Internal Penetration Testing.

Penetration testing exercises your internet-facing and internal infrastructure the way an attacker would — manually, methodically, and with the intent to chain weaknesses into real impact. Automated scanners find low-hanging fruit; our operators find the exploitable misconfigurations that scanners miss.

External testing measures your perimeter exposure: exposed services, weak authentication, forgotten subdomains, and the kinds of edge-case findings that fuel real breaches. Internal testing assumes a foothold and measures how far an attacker could go — Active Directory abuse, privilege escalation, and lateral movement to your most sensitive assets.

Every finding is exploited (or proved exploitable) under controlled conditions, then documented with reproduction steps, business impact, and remediation guidance your engineering teams can act on the same day.

  • Network exploitation testing
  • Privilege escalation analysis
  • Internal lateral movement testing
  • Infrastructure attack validation

Methodology

How we run the engagement.

01

Discovery & Mapping

Comprehensive enumeration of your in-scope assets — services, hosts, applications, and identities — to build an accurate attack surface map.

02

Vulnerability Identification

Manual and tool-assisted analysis to surface exploitable misconfigurations, missing patches, and design weaknesses.

03

Controlled Exploitation

Vulnerabilities are exploited safely to prove impact and validate which findings actually matter versus which are noise.

04

Reporting & Retest

Severity-ranked report with reproduction steps and remediation guidance, followed by a complimentary retest after fixes ship.

Outcomes

Measurable impact, not vanity metrics.

  • Validated, exploit-proven list of vulnerabilities — no false positives
  • Clear attack paths from external exposure to internal compromise
  • Risk-prioritized remediation roadmap your engineers can execute
  • Audit-ready evidence for ISO 27001, SOC 2, PCI DSS, and similar frameworks
Deliverables

What lands in your inbox.

  • Technical findings report with CVSS scoring and reproduction steps
  • Executive summary with risk heat-map
  • Remediation tracker with owner and effort estimates
  • Free retest of fixed findings within 30 days
Frequently Asked Questions

The questions clients ask most.

Should we do external or internal testing first?

We recommend both in the same engagement — external testing measures perimeter exposure, internal testing measures blast radius. Tested together they give a complete picture of how an attacker would move from internet to crown-jewel.

How often should we pentest?

At least annually for stable environments, and after any major infrastructure or application change. Regulated industries often require quarterly or post-deployment testing.

Will testing affect uptime?

Our testing is non-disruptive by default. Destructive techniques (DoS, fuzzing of fragile services) are only used in agreed test windows, if at all.
