Internal Infrastructure Penetration Testing
If an attacker gets a foothold - a phished laptop, a stolen VPN credential, a compromised contractor - what happens next? Pentiq's internal penetration test answers that question with a controlled simulation across your internal network, mapping how far a real attacker could realistically go from the moment they land inside.
Testing Focus
Comprehensive internal network security assessment
Lateral Movement
Testing movement between network segments and systems using techniques like Pass-the-Hash, Kerberos relay, and credential theft.
Privilege Escalation
Identifying paths to root or local-admin access through system misconfigurations and vulnerability exploitation.
Network Segmentation
Validating the effectiveness of network controls, VLANs, firewalls, and micro-segmentation implementations.
Endpoint Security
Assessing workstation and server hardening, local privilege escalation, and endpoint protection bypass.
Service Vulnerabilities
Identifying and exploiting vulnerabilities in internal services, databases, and applications.
Egress & Monitoring
Testing whether internal systems can reach attacker-controlled infrastructure - and whether anyone notices.
Attack Scenarios
Realistic internal threat simulation
Compromised User Account
Starting from a standard user account compromise through phishing or malware.
Insider Scenario
Testing what a trusted user could reach with legitimate network credentials - whether through misuse, mistake, or a compromised account.
Physical Access
Assessing impact of physical access to offices, server rooms, or network infrastructure.
Stolen Laptop
Evaluating network access possible from a compromised corporate device.
Guest Network Pivot
Testing whether guest or contractor networks can access corporate resources.
IoT Device Compromise
Assessing lateral movement from compromised IoT or operational technology devices.
Common Findings

Unnecessary service exposure
Weak endpoint protection
Excessive user privileges
Insufficient monitoring
Legacy system vulnerabilities
Insecure service configurations
Permissive egress policies
Default credentials on internal services
Cleartext protocols on the wire
Common questions
Frequently asked questions.
Do you need physical access to our network?
No. Internal testing is typically performed via a remote drop box or VPN-tunneled connection from our office. We agree the access method during scoping.
What's the scope of an internal pen test?
Internal infrastructure tests cover Active Directory, lateral movement paths, privilege escalation, network segmentation, and service-level vulnerabilities across the agreed in-scope IP ranges. We confirm exact scope at the kick-off call.
How disruptive is internal testing?
Testing is tuned to be safe against modern infrastructure. We agree change windows and rate limits at scoping; fragile legacy systems can be flagged out of scope or have testing approach adjusted accordingly.
Will testing trigger our SOC or EDR?
It usually will, and that's intentional in some engagements. We can run loud (so detection is triggered, useful for purple-team exercises) or quiet (assumed breach, evading detection). Tell us which you want.
