Network Penetration Testing Services
Your network is your organisation’s backbone. A single unpatched vulnerability, misconfigured firewall rule, or weak credential can give attackers a direct path to your most sensitive data. Intrix Cyber Security’s network penetration testing simulates real-world attacks against your infrastructure to find weaknesses before cybercriminals do.
What Is Network Penetration Testing?
Network penetration testing is a controlled, authorised simulation of a cyber attack against your organisation’s network infrastructure. Our CREST-certified ethical hackers use the same techniques as real-world attackers to identify vulnerabilities in your firewalls, routers, switches, servers, and endpoints.
Unlike automated vulnerability scanning, penetration testing involves manual exploitation of discovered weaknesses to determine real-world impact — including whether an attacker could move laterally through your
network, escalate privileges, or exfiltrate sensitive data.
Internal & External Network Penetration Testing Australia
External Network Penetration Testing
We simulate an attacker with no internal access, targeting your internet- facing infrastructure:
Perimeter firewall and router configuration review
Public-facing server and service enumeration
Remote access gateway testing (VPN, RDP, Citrix)
DNS, email, and web server security assessment
SSL/TLS configuration analysis
Public IP range reconnaissance
Internal Network Penetration Testing
We simulate a threat actor who has gained initial access (compromised employee, rogue insider, or breached endpoint):
Active Directory security assessment
Privilege escalation testing
Lateral movement and pivoting
Network segmentation validation
Credential harvesting and pass-the-hash attacks
Sensitive data discovery and exfiltration testing

Reporting & Remediation
Detailed technical report with executive summary, risk ratings, evidence, and prioritised remediation guidance.
Frequently Asked Questions
What is the difference between a vulnerability scan and a penetration test?
Yes, when authorised. We operate under a signed Statement of Work with clear rules of engagement, authorised scope, and emergency contacts. Our testers carry authorisation letters at all times.
How often should we conduct network penetration testing?
Most organizations conduct network penetration testing at least once a year. However, additional testing is recommended after major infrastructure changes, system upgrades, or when new applications and services are introduced to ensure new vulnerabilities have not been created.
Will penetration testing disrupt our business operations?
Penetration testing is carefully planned to minimize disruption. Our team coordinates with your IT staff to schedule testing during appropriate times and uses controlled techniques to avoid impacting critical systems or normal business operations.
How long does a network penetration test take?
The duration depends on the size and complexity of the network. Small networks may take a few days, while larger or more complex environments can take one to two weeks to complete a comprehensive assessment.
What do we need to provide before testing begins?
Before testing starts, we typically require details such as the scope of the network, authorized IP ranges, contact information for key personnel, and written authorization to perform the test. This ensures the testing is conducted safely and within agreed boundaries.
Do you provide a retest after remediation?
Yes, we offer retesting after vulnerabilities have been fixed. This helps verify that the issues have been properly resolved and ensures your systems are protected against the previously identified security risks.
