Network Security Assessments

Beyond Basic Vulnerability Scanning

Your network infrastructure is the foundation that connects all your critical business systems, but it’s also the primary pathway that attackers use to move through your environment. Traditional vulnerability scanners can tell you what’s broken, but they can’t tell you what matters most or how an attacker would actually exploit your environment. Our Network Security Assessments go far beyond basic scanning to provide the strategic insights you need to build a truly resilient network defense.

The Modern Network Security Challenge

Today’s network environments are more complex and challenging to secure than ever before:

Expanding Attack Surface

Cloud-first architectures with distributed workloads and services
Remote workforce connectivity through VPNs, zero trust networks, and direct cloud access
IoT and OT integration bringing operational technology onto corporate networks
Third-party integrations creating trust relationships with external entities

Sophisticated Threat Techniques

Living off the land attacks using legitimate network tools and protocols
Lateral movement techniques that hop between systems using network pathways
Traffic analysis and interception targeting sensitive data in transit
Network-based persistence mechanisms that survive system reimaging

Compliance and Regulatory Requirements

PCI DSS network segmentation requirements
HIPAA network controls for healthcare data protection
SOX network security for financial system integrity
Industry-specific frameworks with network security mandates

Operational Complexity

Hybrid cloud architectures spanning on-premises and multiple cloud providers
Software-defined networking with dynamic routing and micro-segmentation
Container networking with ephemeral workloads and service meshes
Legacy system integration requiring network bridges and translation layers

Our Strategic Assessment Approach

Comprehensive Network Discovery

We begin with a thorough understanding of your network landscape:

Asset Identification and Classification

Complete network topology mapping using active and passive discovery techniques
Asset inventory including servers, workstations, network devices, and IoT systems
Service enumeration to understand what’s running where
Data flow analysis to map how information moves through your network

Architecture Analysis

Network segmentation assessment to understand security boundaries
Trust zone identification and inter-zone communication analysis
Critical asset location mapping relative to network security controls
Network device configuration review for security best practices

Attacker-Focused Testing

We think like attackers to identify the paths they would actually use:

Lateral Movement Analysis

Privilege escalation pathway identification through network services
Cross-system communication vulnerability assessment
Network protocol exploitation testing for common attack vectors
Credential harvesting opportunities through network services

Network-Based Attack Simulation

Man-in-the-middle attack feasibility testing
Network traffic interception and analysis capabilities
Rogue device placement impact assessment
Wireless network security evaluation including guest and corporate networks

Advanced Threat Techniques

Living off the land attack pathway identification
Network-based persistence mechanism discovery
Covert channel communication possibilities
Network forensic artifact availability assessment

Business Impact Analysis

We prioritize findings based on actual business risk:

Critical Asset Protection
