Network Security Assessment

Hybrid work and SD-WAN adoption have dramatically expanded enterprise attack surfaces.

Traditional perimeter-based security models are no longer sufficient, and organizations are

shifting to zero-trust architectures. A network security assessment is the essential first step in

understanding where your perimeter actually stands.

Key Benefits

•External and internal network scanning and topology mapping

•Firewall rule analysis for unnecessary exposure and policy drift

•Network segmentation testing can attackers move laterally once inside?

•Wireless network security review including rogue AP detection

•Actionable findings prioritized by exploitability and business impact

What We Do

Securiglobe’s Network Security Assessment provides a thorough evaluation of your internal and

external network infrastructure from firewall rule reviews and segmentation analysis to traffic

monitoring and device configuration audits. We identify paths an attacker could use to move

through your network undetected.

How It Helps Your Business

Your network is the highway attackers travel once they’re inside. A network security assessment

tells you where the roads are, which ones are unguarded, and how to put up the right

checkpoints supporting both your security posture and business continuity.

What We Assess

Network topology, segmentation design, DMZ configuration, trust zone mapping, and traffic flow analysis

Firewall rule review, IDS/IPS configuration, exposed services, port scanning, and external attack surface mapping

VLAN configuration, inter-VLAN routing controls, microsegmentation, and lateral movement paths

Router and switch hardening, management access controls, firmware versions, SNMP configuration

Wi-Fi authentication, encryption standards, rogue AP detection, guest network isolation

VPN configuration, split tunnelling, MFA enforcement, remote desktop exposure

SIEM integration, NetFlow logging, alerting coverage, and traffic baseline review

DNS security extensions, internal DNS hygiene, DHCP snooping, and rogue server risk

Our Process

We map your network topology, identify all in-scope devices, and agree assessment boundaries with your team.

Analysis of network design documents, firewall policies, segmentation diagrams, and change records to identify design-level weaknesses.

Credentialed and uncredentialed scanning of network devices, services, and traffic flows across the defined scope.

Review of firewall ruleset, router ACLs, switch configurations, and network management plane settings against CIS benchmarks.

Review of NetFlow data, DNS query logs, and monitoring system alerts to identify anomalous patterns and coverage gaps.

All findings are rated by severity and exploitability. A full technical report and executive summary are delivered with a prioritised remediation plan.

Frequently Asked Questions

Will the assessment affect our network performance?

We schedule active scanning during off-peak hours and use scan profiles that minimise bandwidth and device load. Network performance impact is negligible

Do you need administrative access to our devices?

Credentialed assessment provides deeper insight into device configurations. We work with your team to establish read-only access through a secure, audited process.

How often should a network security assessment be conducted?

We recommend a full assessment annually and after any major network changes — such as acquisitions, new site additions, or significant infrastructure upgrades
