Network Testing Services That Map Every Path Into Your Infrastructure

Our network testing services cover external network penetration testing from the internet-facing perimeter, internal network penetration testing from a simulated compromised position, wireless network security testing, network segmentation validation, vulnerability identification with controlled exploitation, lateral movement testing, and a detailed findings report with CVSS ratings, exploitation evidence, and remediation guidance.

External network penetration testing starts from outside your network with no prior access and tests what an outside attacker could accomplish against your internet-facing assets. Internal network penetration testing starts from a position inside your network — representing a compromised device or insider threat — and tests what that access position could reach across your internal environment. Both are necessary because perimeter controls reduce but do not eliminate the risk of internal compromise.

A vulnerability scanner identifies known vulnerabilities through pattern matching against a database. Network pen testing chains vulnerabilities, tests whether findings are actually exploitable, explores what access each exploitable condition enables, and simulates the lateral movement that turns an initial foothold into access to your most sensitive systems. The chained, contextual attack paths that pen testing produces are what scanners cannot identify because they evaluate each finding in isolation.

Network segmentation testing actively attempts to pass traffic between segments that should be isolated from each other — the cardholder data environment and the rest of the network in the PCI DSS context. If traffic passes, the segmentation is not effective regardless of how the firewall rules are documented. PCI DSS Requirement 11.4.5 specifically requires penetration testing to validate segmentation controls, making segmentation testing a compliance obligation rather than an optional security activity.

Our internal network security testing for hybrid environments covers on-premises network attack paths and the connectivity layer between on-premises infrastructure and cloud platforms, including VPN security, cloud gateway configurations, identity federation trust relationships, and lateral movement paths that cross between the on-premises and cloud environments rather than staying within one.

Wireless network security testing covers authentication protocol weaknesses for each SSID, rogue access point detection, the segmentation between corporate and guest wireless networks, and the paths that a wireless compromise could use to reach wired internal systems. Each SSID is assessed separately because corporate, guest, and IoT networks carry different access levels and different risk profiles.

Network infrastructure penetration testing for environments with legacy equipment specifically accounts for the vulnerability categories that older systems carry — unpatched CVEs in end-of-support operating systems, weak cryptographic protocols still active on legacy devices, default credentials on older network hardware, and SNMP community strings that provide network-wide visibility to anyone who knows the community name.

A standard external network pen testing services engagement for a small to medium organization takes one to two weeks from scoping through report delivery. Internal testing, wireless coverage, and segmentation validation extend that timeline. Complex environments with large IP ranges, multiple segments, and hybrid infrastructure take two to four weeks. Timeline is confirmed during the scoping conversation before testing begins.

Yes. Most cyber insurance carriers that require penetration testing accept network vulnerability testing reports that meet minimum scope and methodology requirements — external testing at minimum, often internal testing as well. We can confirm the specific requirements of your carrier’s application before scoping the engagement so the report we deliver satisfies what they need without requiring additional testing.

After your team completes remediation, we conduct a targeted retest of confirmed findings to verify that each fix addresses the specific vulnerability identified rather than only the surface symptom. Retest results are documented in a remediation validation addendum to the original report that satisfies the retesting requirements in PCI DSS, SOC 2, and most cyber insurance frameworks.
