Network Penetration Testing

We attack your network the way a real adversary would: live tools, manual techniques, and lateral movement — to find every gap before someone else does.

What is a network penetration test?

A network penetration test is a controlled, authorized attack on your network infrastructure. Our team of certified ethical hackers deploys the same tools and techniques used by malicious threat actors to identify vulnerabilities in your systems, escalate privileges, and determine how far a real attacker could penetrate your environment.

Unlike automated vulnerability scanners, our manual methodology allows us to chain vulnerabilities together, discover business logic flaws, and uncover attack paths that software simply cannot identify. The result is a true picture of your risk, not a list of theoretical issues from a tool.

Scope options

External Network Testing

Simulates an outside attacker targeting your internet-exposed infrastructure — web servers, VPNs, mail gateways, firewall rules, and more.

Internal Network Testing

Simulates a threat from inside your perimeter — an insider threat, compromised endpoint, or lateral movement post-breach scenario.

Wireless Network Testing

Tests the security of your wireless infrastructure, including segmentation, rogue AP detection, and encryption weaknesses.

Our testing methodology

Reconnaissance: Active and passive intelligence gathering on all in-scope targets.
Scanning & Enumeration: Mapping all reachable hosts, services, and potential entry points.
Vulnerability Mapping: Identifying exploitable weaknesses, misconfigurations, and unpatched systems.
Exploitation & Privilege Escalation: Attempting to exploit findings and escalate access across the network.
Lateral Movement: Determining how far a breach could extend from the initial point of compromise.
Documentation & Reporting: Detailed findings with severity ratings, evidence, and prioritized remediation steps.

Based in New York. Working Nationwide.

Grid32 is headquartered in Jersey City, New Jersey and has conducted penetration tests for organizations across the United States since 2009 — from financial institutions and law firms in New York City to technology companies on the West Coast and enterprises throughout the country. Our engagements are conducted remotely, which means geography is never a constraint. We are particularly well-versed in the regulatory environment facing New York-based organizations, including financial institutions regulated under NYDFS (23 NYCRR 500) and healthcare organizations subject to HIPAA.

Ongoing Vulnerability Assessments

For clients who complete an annual penetration test with Grid32, we also provide ongoing quarterly vulnerability assessments — keeping your environment monitored and validated between full test cycles. This combination gives you both depth and continuity. Ask us about adding quarterly VAs to your program →
