Network penetration testing that finds the way in.
Your network is the backbone of the business, and every device, service, and connection is a potential way in. SubRosa's network penetration testing exposes the internal and external weaknesses an attacker would chain together, then hands you a prioritized path to close them.

What is network penetration testing?
Network penetration testing is a controlled attack on your network infrastructure, both external (internet-facing) and internal, to find and safely exploit the weaknesses a real attacker would use: unpatched devices, weak configurations, exposed services, and paths for lateral movement. The goal is not a list of scanner output but proof of what an attacker could actually reach, and a clear plan to shut it down.
External and internal, every layer.
From your internet-facing perimeter to the inside of your network, we test everything an attacker would target.
External network testing
We attack your internet-facing perimeter the way an outside adversary would: exposed services, VPN and remote access, misconfigurations, and known-exploitable vulnerabilities.
Internal network testing
From an assumed-breach position inside the network, we test segmentation, privilege escalation, and lateral movement, showing how far an attacker gets once they are in.
Full infrastructure coverage
Routers, switches, firewalls and IDS/IPS, load balancers, VPN concentrators, DNS and DHCP, and file, mail, and database servers, all tested against real attack techniques.
Actionable reporting & retest
An executive summary, a detailed technical report with reproduction and remediation steps, a prioritized roadmap, and complimentary retesting once you have fixed the findings.
Offensive depth, business context.
20+ years breaking in
Two decades of hands-on offensive work across every kind of network, so testing reflects how attackers actually operate rather than a checklist.
Real exploitation, not scans
We safely chain and exploit findings to prove real-world impact and validate your controls, going well beyond automated scanner output.
Prioritized by real risk
Every finding is ranked by the risk it carries and the access it grants, so your team fixes what matters first.
From report to remediation.
Your network pen test findings land in Sable, prioritized, assigned, and tracked from open to retested, so remediation becomes a managed workflow instead of a PDF that gets forgotten.
