Internal Pentest vs Active Directory Security Assessment

Both internal penetration tests and Active Directory security assessments are valuable, but they address different questions and priorities.

Primary Focus

Internal Penetration Test: Finds exploitable vulnerabilities across internal hosts, applications, and services. Often CVE-driven and host-focused.

AD Security Assessment: Finds and breaks attack chains that lead to domain compromise. Identity-focused and relationship-driven.

Typical Output

Internal Pentest: Vulnerabilities by host, often organized by system or application. May include AD enumeration and attacks, but AD is one component among many.

AD Security Assessment: Attack paths, privilege relationships, and identity control failures. AD is the center of the assessment.

What Gets Missed

Internal Pentest: Often misses subtle privilege chains, delegated admin abuse, trust relationships, and identity misconfigurations that do not show up in vulnerability scans.

AD Security Assessment: Very little in AD scope, since AD is the focus. May miss host-level vulnerabilities outside of identity systems.

Identity Hygiene

Internal Pentest: Usually limited or out of scope. Focus is on exploitable vulnerabilities.

AD Security Assessment: Included. Examples include stale accounts, privilege sprawl, risky DC services, and KRBTGT rotation signals.

Methodology

Internal Pentest: Often starts from unauthenticated access and expands via exploitation across multiple systems.

AD Security Assessment: Three-phase approach: unauthenticated, standard user, then Domain Admin for maximum coverage of identity issues.

Remediation Approach

Internal Pentest: Fix the findings, often one host at a time.

AD Security Assessment: Clear fixes plus a roadmap for short-term, medium-term, and long-term improvements that break attack chains.

When to Choose Each

Choose an internal pentest when:

• You need broad vulnerability coverage across your network
• You want to test multiple systems and applications
• You need to validate patch management and host security

Choose an AD security assessment when:

• You need to understand identity takeover risk specifically
• You want to break attack chains before they become incidents
• You already run internal pentests but want deeper identity coverage
• You need a roadmap for AD hardening and hygiene improvements

Complementary Approaches

If you already run internal pentests, an AD security assessment complements them by covering identity takeover risk that scans and host-driven testing often miss.
