Internal Network Penetration Testing for Small Businesses

 

What Is Internal Network Penetration Testing?
Internal network penetration testing simulates what a malicious actor could do after gaining access to your internal systems — whether through phishing, compromised credentials, or a rogue employee.

We simulate real-world attacks from inside your environment to identify weaknesses in:

1.) Internal servers

2.) File shares

3.) Domain controllers

3.) Active Directory configurations

4.) Network segmentation

5.) Credential storage and reuse

6.) Workstation security policies

Think of it as a “fire drill” for your internal cybersecurity defenses — so you can fix weaknesses before they’re exploited.

Why It Matters for Small Businesses
Most attacks today don’t come from the outside — they come from:

1.) Phished employees

2.) Infected devices

3.) Compromised VPNs

4.) Misconfigured internal access

Once inside, attackers can:

A.) Access sensitive client or financial data

B.) Move laterally to higher-value systems

C.) Escalate privileges to become domain admins

D.) Drop ransomware and disrupt your entire business

Small businesses are especially at risk because they often lack proper segmentation, least privilege controls, and logging.

What We Test During an Internal Pentest
Our internal penetration test includes:

1.) Workstation & Server Enumeration

2.) OS fingerprinting, patch levels, and privilege checks

3.)  User & Credential Attacks

4.) Password reuse, hash dumping, credential spraying

5.) Shared Drive & File Server Exploits

6.) Sensitive files, open shares, misconfigured permissions

 Network Segmentation & Lateral Movement

Can an attacker jump from one department to another?

A.) Active Directory Misconfigurations

B.) Kerberoasting, AS-REP roasting, GPP password abuse

Privilege Escalation & Exploit Paths

Can we become an admin with basic access?
