What Is Internal Infrastructure Penetration Testing?

Internal penetration testing simulates what an attacker — or malicious insider — could do once they gain a foothold inside your network.

It’s designed to test your internal defenses, detect weak points in architecture, and assess how far an attacker could move without being noticed.

Why It Matters

Perimeter defenses aren’t enough. Once inside — through phishing, stolen credentials, VPN misconfigurations, or supply chain compromise — attackers often find:

  • Poor segmentation
  • Overly trusted services
  • Reused or weak passwords
  • Unpatched systems
  • Legacy applications
  • And no real detection

Internal pentesting helps you:

  • Uncover real paths to domain compromise
  • Evaluate segmentation and access control
  • Spot privilege escalation opportunities
  • Test detection and response capabilities
  • Strengthen zero trust and defense-in-depth strategies

If you’re operating in a hybrid setup (on-prem + cloud), or if employees and services have access to internal resources — this test is essential.

What We Test

We simulate a low-privileged attacker inside your network and methodically map out escalation paths. This includes:

  • ✅ Network enumeration and lateral movement
  • ✅ Service and protocol exploitation (SMB, RDP, etc.)
  • ✅ Password reuse, credential harvesting
  • ✅ Privilege escalation on workstations and servers
  • ✅ Active Directory enumeration and attacks
  • ✅ Domain controller takeover simulation
  • ✅ Internal application abuse
  • ✅ Misconfigurations and outdated software

The goal: show what an attacker could do — and how to stop them early.

What We Deliver

At Cloud Tribe, we provide real insight — not just vulnerability noise. Our internal infrastructure pentests come with:

  • ✅ A structured, attack-path-driven assessment
  • ✅ Technical findings with real impact analysis
  • ✅ Clear remediation steps prioritized by risk
  • ✅ Executive summary for leadership
  • ✅ Optional retesting to confirm improvements

You can’t defend what you can’t see.

With Cloud Tribe, you’ll know exactly how secure your internal environment really is — and what to fix to make it stronger.
