External network testing
We test what an attacker on the open internet can see and exploit.
Find Weaknesses Before They Become Breaches
Expert Network Security Assessment & Penetration Testing Services
Your network is the foundation of your business, and a single weakness can expose your entire environment. PlutoSec simulates real world attacks to uncover misconfigurations, weak access controls, and exploitable vulnerabilities before attackers do.
- Certified Network Penetration Experts
CEH and CompTIA Security+ certified engineers evaluate your network architecture and defenses.
- Real World Approach
We test firewalls, segmentation and configurations against techniques real attackers use to move laterally.
- Detailed Reporting
Findings come with a clear risk rating and practical steps to strengthen your network posture.
- Confidential & Secure
Network diagrams and assessment data stay protected under strict confidentiality agreements.
Experts in Network Penetration Testing
About Network Pentest
Network penetration testing examines your servers, firewalls, switches, and other infrastructure for the kind of weaknesses attackers actually use to move through an environment: outdated software, weak credentials, exposed services, and misconfigured access controls. It goes beyond a vulnerability scan by attempting to chain smaller issues together into the kind of attack path a real intruder would use.
Most networks grow over time, picking up legacy systems, forgotten services, and inconsistent configurations along the way. A network penetration test gives you a realistic view of how an attacker, whether external or already inside your network, could move laterally, escalate privileges, and reach sensitive systems. It's one of the most direct ways to validate that your infrastructure can actually withstand a real attempt.

Frequently asked questions
Answers to the questions we hear most. Still unsure how it applies to your environment? Our engineers are happy to talk it through.
What's the difference between internal and external network testing?
External testing simulates an attacker on the open internet with no prior access. Internal testing simulates an attacker, or a compromised device, that's already inside your network.
Will network testing cause downtime?
We schedule testing windows and use controlled exploitation methods specifically to avoid disrupting business operations or critical systems.
How often should we run a network penetration test?
Most organizations test once or twice a year, and after any major infrastructure change, new data centre, new office, or significant network redesign.
Do you test cloud infrastructure too?
Yes, we test virtual networks and exposed services in AWS, Azure, and GCP as part of our network testing scope, or as a standalone cloud assessment.
What do we receive after the test?
A full report with categorized findings, proof of exploitation where applicable, business impact, and step-by-step remediation guidance, plus a free retest.
Is this the same as a vulnerability scan?
No. A scan identifies known issues automatically. Our testers manually validate and exploit those issues to confirm real risk and uncover what automated tools miss.
