Is your network truly safe from attacks? If you’ve recently made changes to your network or are planning to, a Network Architecture Review could be the difference between vulnerability and resilience.
The Network Architecture Security Review is a critical evaluation of your organization’s network design to identify weaknesses, assess gaps in existing security controls, and ensure alignment with your security objectives. At Securis360, we offer customizable packages tailored to your budget, helping you safeguard your business operations and critical infrastructure.
Our network architecture reviews go beyond surface-level assessments. We conduct in-depth technical and strategic evaluations of your network to uncover potential vulnerabilities. This includes reviewing personnel, processes, and technologies to ensure your network is secure from a holistic perspective. Here’s what our review covers:
1. Information Gathering
Our engineers gather comprehensive information about your network in two steps:
2. Analysis of Findings
The collected data is rigorously analyzed to ensure compliance with:
3. Recommendations
We provide a detailed report with actionable recommendations to address vulnerabilities. The report outlines:

With Securis360, your network is evaluated against the highest security standards to ensure resilience against threats.
A Network Architecture Review is a comprehensive assessment of an organization’s network design, infrastructure, segmentation, security controls, connectivity, and performance to identify risks, vulnerabilities, and improvement opportunities.
A secure and well-designed network architecture helps organizations improve cybersecurity, reduce downtime, optimize performance, and support business growth.
The purpose of a Network Architecture Review is to identify security gaps, improve network performance, validate segmentation, reduce attack surface, strengthen access control, and support compliance requirements.
A typical review includes network topology analysis, firewall and routing review, segmentation analysis, VPN security review, cloud connectivity review, access control assessment, and performance evaluation.
Reviews should be conducted annually, after major infrastructure changes, mergers or acquisitions, before compliance audits, and following security incidents.
Common risks include flat network design, weak segmentation, misconfigured firewalls, open ports, legacy protocols, and excessive permissions.
Network segmentation divides networks into smaller isolated zones to improve security and reduce lateral movement risks.
Segmentation helps limit cyberattack spread, protect sensitive systems, improve access control, and support compliance requirements.
A flat network is a network design with minimal segmentation where all systems communicate freely, increasing security risks.
Zero Trust Network Architecture continuously verifies users, devices, and traffic before granting access to resources.
Secure network architecture uses layered security controls, segmentation, firewalls, monitoring, and access management to protect IT environments.
Common weaknesses include weak firewall policies, insecure remote access, poor VLAN segmentation, unsecured Wi-Fi, legacy systems, and lack of monitoring.
A DMZ (Demilitarized Zone) is a secure network segment used to isolate public-facing systems from internal networks.
Defense-in-depth uses multiple layers of security controls to protect systems and networks from cyberattacks.
Network hardening strengthens security by disabling unnecessary services, tightening configurations, and applying security controls.
Firewalls help control traffic flow, enforce security policies, and protect networks from unauthorized access.
Access control restricts user and device access to systems and data based on permissions and security policies.
Least privilege access ensures users and systems only receive the minimum permissions necessary.
Network Access Control verifies device security before allowing access to the network.
Yes. Reviews commonly identify weak rules, exposed services, and insecure access configurations.
Cloud network architecture review evaluates AWS, Azure, and GCP connectivity, segmentation, firewall rules, and cloud security controls.
Hybrid architecture combines on-premise infrastructure with cloud environments.
Common risks include open security groups, weak VPN configurations, publicly exposed workloads, and poor IAM integration.
SD-WAN improves network management and connectivity across distributed offices and cloud environments.
SASE (Secure Access Service Edge) combines networking and security services into a cloud-based architecture.
Wireless security review evaluates Wi-Fi configurations, encryption, guest access, and wireless vulnerabilities.
Common Wi-Fi risks include weak passwords, open guest networks, rogue access points, and weak encryption protocols.
VPN architecture secures remote access connections between users, branch offices, and cloud environments.
Yes. Reviews help secure VPNs, remote access systems, cloud applications, and hybrid work environments.
Yes. Secure network architecture supports ISO 27001, PCI-DSS, HIPAA, SOC 2, and GDPR compliance requirements.
PCI-DSS recommends segmentation to isolate payment card environments from other systems.
Yes. ISO 27001 includes requirements for network protection, access control, and secure communications.
Network monitoring helps identify security incidents, performance issues, suspicious traffic, and unauthorized access.
Network traffic analysis examines data flow patterns to identify anomalies, attacks, and performance bottlenecks.
SIEM integration centralizes logs and security events for threat detection and incident response.
Yes. Reviews identify bottlenecks, latency issues, inefficient routing, and bandwidth limitations.
Common tools include Nmap, Wireshark, SolarWinds, Nessus, Cisco DNA Center, and PRTG Network Monitor.
Yes. They identify vulnerabilities, exposed services, insecure pathways, and attack surfaces.
Network penetration testing simulates cyberattacks to identify exploitable vulnerabilities in systems and networks.
Architecture risk assessment identifies weaknesses in network design that could impact security and business continuity.
Industries include banking, healthcare, telecom, manufacturing, government, SaaS, and education.
Cost depends on infrastructure size, locations, cloud integration, security scope, and compliance requirements.
Reports include risk findings, architecture diagrams, security gaps, segmentation analysis, and remediation roadmap.
Common mistakes include flat networks, weak segmentation, open firewall ports, legacy protocols, and lack of monitoring.
Yes. Zero Trust is becoming a standard security model for modern enterprise networks and cloud environments.
Yes. Poor design increases attack surface and enables easier lateral movement for attackers.
Micro-segmentation creates highly granular security zones to limit attacker movement within networks.
Future trends include Zero Trust, AI-driven monitoring, cloud-native networking, SASE adoption, and software-defined security.
Regular architecture reviews, penetration testing, monitoring, and compliance assessments help evaluate security.
Look for certified experts, cloud and hybrid experience, firewall knowledge, compliance expertise, strong reporting, and remediation support.
