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 Architecture Review

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

Perimeter Security

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

Internal Segmentation

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

Network Device Security

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

Wireless Security

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

Remote Access

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

Network Monitoring

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

DNS & DHCP Security

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 a network security assessment affect our network performance?

Our network security assessment services are designed to minimize impact on production environments. Active network security testing is scheduled during off-peak hours, and scan profiles are configured to reduce bandwidth consumption and device load. With proper scoping and rate limiting, network performance impact is typically negligible.

Do you need administrative access to our network devices?

Administrative access is not always required. A credentialed network security assessment can provide deeper visibility into device configurations, security controls, and vulnerabilities. Where access is required, we work with your team to establish secure, read-only access through an audited process.

How often should a network security assessment be conducted?

We recommend conducting a comprehensive network security assessment at least annually and after significant changes to your environment. This includes acquisitions, new office or site additions, major infrastructure upgrades, network architecture changes, and deployment of new critical systems.

What does a network security assessment include?

Our network security assessment services can include network discovery, vulnerability identification, security configuration review, exposed-service analysis, firewall and network-device assessment, segmentation review, and controlled network penetration testing where applicable. The scope is customized based on your infrastructure and security requirements.

Do you provide network security assessment services in India?

Yes. Our network security assessment services in India help organizations identify vulnerabilities, misconfigurations, exposed services, and weaknesses across their network infrastructure. Assessments can cover on-premises networks, remote offices, data centers, network devices, and hybrid environments.

What is the difference between a network security assessment and a network vulnerability assessment?

A network vulnerability assessment primarily identifies known vulnerabilities and security weaknesses across network assets. A broader network security assessment evaluates vulnerabilities alongside configurations, access controls, network architecture, segmentation, exposed services, and other security controls to provide a more comprehensive view of the organization’s network security posture.
