Infrastructure Penetration Testing Services
Manual penetration testing for your servers, networks, and on-premise systems. PlutoSec identifies exploitable vulnerabilities with zero false positives.
Why Infrastructure Penetration Testing Is the Foundation of Cyber Defense
Applications get a lot of attention in security conversations, but the servers, networks, and systems underneath them are often where attackers actually get a foothold. Unpatched operating systems, weak credentials on internal services, outdated protocols still running for legacy reasons, and overly trusting network segments are the building blocks of most successful breaches. PlutoSec's infrastructure penetration testing services manually test your internal and external network infrastructure the way a real attacker would, from initial access to lateral movement, so you know exactly how far a compromise could go and where to stop it.
What Infrastructure Testing Reveals
Realistic Assessment of Attack Impact
A realistic picture of how far an attacker could get if they breached your perimeter or got a foothold internally
Our Infrastructure Penetration Testing Process
We test infrastructure the same way an attacker would approach it: starting from the outside, then moving to what happens once someone gets inside, because both perspectives matter for understanding your real risk.
- 1
We map your external and internal infrastructure, including IP ranges, network segments, and key systems in scope
- 2
Our team manually tests internet-facing systems for vulnerabilities that could provide initial access
- 3
We simulate an attacker who already has internal access, testing lateral movement, privilege escalation, and access to sensitive systems
- 4
Where appropriate, we safely exploit identified vulnerabilities to confirm real-world impact, not just theoretical risk
- 5
We deliver a detailed report with prioritized findings and offer retesting once remediation is complete

Our Infrastructure Penetration Testing Services
External Network Penetration Testing
Testing of internet-facing systems, servers, and network devices for exploitable vulnerabilities
Internal Network Penetration Testing
Simulated attacks from inside your network to test lateral movement and access to critical systems
Active Directory Security Assessment
Testing focused on common Active Directory misconfigurations and privilege escalation paths
Server and Endpoint Hardening Review
Assessment of operating system configurations, patch levels, and hardening across servers and endpoints
Network Segmentation Testing
Validation that segmentation between network zones actually limits attacker movement as intended
Why PlutoSec for Infrastructure Penetration Testing
Manual Testing That Shows the Full Attack Path
Infrastructure penetration testing is one of the areas where automated scanning falls shortest, because the most dangerous findings often come from chaining several smaller issues together, something a scanner cannot do. Our certified team, holding credentials including OSCP, GPEN, and GPENT, manually tests your infrastructure with the same persistence and creativity a real attacker would bring. We do not stop at the first vulnerability we find. We follow it through to understand what it actually means for your business, then deliver a report with zero false positives that your team can act on immediately.
