Internal Network Penetration Testing

Simulate an insider breach and see how far an attacker can reach

NeedSec conducts internal network testing from within your environment — simulating a compromised device, malicious insider, or attacker who has bypassed your perimeter. We identify lateral movement paths, privilege escalation routes, and which systems an attacker could realistically reach.

Manual-led testing

Every assessment is led by a qualified security engineer — human judgment, not just automated scanning.

Evidence-backed findings

Each vulnerability includes proof of concept, reproduction steps, and a business-impact risk rating.

Actionable fix guidance

Reports are structured for developers and decision makers so remediation can start immediately.

What We Test

Focused testing against realistic attack paths

NeedSec combines manual testing, structured methodology, and business-focused reporting to identify issues that matter — not just scanner noise.

01

Internal network scanning — live hosts, open ports, and running services

02

Active Directory enumeration — users, groups, GPOs, and trust relationships

03

Kerberoasting, AS-REP roasting, and credential abuse techniques

04

Weak and default credentials across services, shares, and endpoints

05

Lateral movement path mapping — pass-the-hash, pass-the-ticket

06

Privilege escalation — local admin to domain admin attack paths

07

Network segmentation validation — VLAN bypass and cross-segment access

08

SMB, RPC, and Windows protocol abuse testing

09

Internal web applications, admin panels, and management portals

10

Sensitive data discovery — file shares, databases, and credential stores

11

Post-exploitation impact analysis — access to critical business systems

12

Detection and logging gap observations
