Assessing the infrastructure that connects and protects your business.
Network security testing assesses the infrastructure connecting your business, perimeter, internal segmentation, and identity systems, for the misconfigurations that let an attacker move from initial access to full compromise.
Your network is the foundation everything else runs on. We assess perimeter defenses, internal segmentation, and the services exposed across your infrastructure to identify paths an attacker could use to gain and expand access.
Engagements can be scoped as external-only, internal (assumed breach), or a combination of both to reflect realistic threat scenarios.
Segmentation and perimeter weaknesses are what turn a single compromised laptop into a company-wide incident. Fixing them proactively limits the blast radius of any future incident, which many organizations see reflected in lower cyber-insurance premiums.
A clear picture of your network's actual exposure lets leadership make informed infrastructure investment decisions, instead of spending reactively after something goes wrong.
Every day undetected is a day of exposure.

From perimeter to attack path
A perimeter scan, a lateral-movement test from an internal foothold, and an Active Directory misconfiguration found along the way, assessed the way an attacker would actually move.

An illustrative walkthrough of how an engagement actually runs, not footage from a real client environment.
KazaSec itself runs behind Cloudflare, the same DDoS mitigation, WAF, and bot protection layer we assess and help configure for clients. Cloudflare's network has passed 500 Tbps of capacity across 330+ cities, and its H1 2026 DDoS Threat Report recorded 805 network-layer attacks exceeding 1 Tbps mitigated in Q2 2026 alone, a 519% surge in hyper-volumetric attacks over the prior quarter.

Process
Agree on network ranges, environments, and testing windows.
Enumerate hosts, services, and exposed protocols.
Attempt to gain, escalate, and pivot access where safe to do so.
Map findings to segmentation and identity risk.
Deliver a prioritized report with network diagrams and evidence.
Validate remediation of critical and high-risk findings.
We agree rules of engagement in advance, including blackout windows and any systems requiring careful handling, to minimize risk of disruption during testing.
Yes, for cloud-native network configurations (VPCs, security groups, peering), this typically pairs with our Cloud Security service for full coverage.
Yes, Active Directory and broader identity infrastructure is one of the most common paths from initial access to full domain compromise, and it's a standard part of an internal network assessment, not an add-on.
We agree on handling for fragile or legacy systems during scoping, that can mean lighter-touch testing, a maintenance-window schedule, or excluding a specific system from active exploitation while still assessing its exposure passively.
Yes, where useful for the finding, attack paths and segmentation issues are often clearer shown visually than described in prose alone, and we include diagrams in the report where they add real clarity.
Our methodology for network security is grounded in established, publicly available frameworks, not a proprietary checklist.
Share a few details about your environment and we'll help you scope the right engagement.
