Network Security Expertise You Can Trust

Your network is the backbone of your business operations. Every server, endpoint, and device connected to it is only as secure as the network itself. At Codesecure Solutions, we specialize in identifying and eliminating vulnerabilities within network infrastructure through thorough network penetration testing, firewall configuration audits, and Active Directory security assessments. Our approach covers both external-facing perimeter defenses and internal network segments where lateral movement attacks often go undetected.

As a focused network security company in Chennai, we bring hands-on experience in testing complex enterprise networks, multi-site architectures, and hybrid cloud environments. We help you understand exactly where your network is vulnerable and provide clear steps to fix each issue.

Our Network Security Services

We provide specialized testing across every layer of your network infrastructure, identifying risks that could allow unauthorized access or data compromise.

  • Network Penetration Testing - External and internal testing to find exploitable paths, open ports, weak protocols, and misconfigured services
  • Firewall Configuration Audit - Rule-by-rule analysis of your firewall policies to identify overly permissive rules, redundancies, and security gaps
  • Active Directory Assessment - Evaluation of AD configurations, group policies, privilege assignments, and Kerberos authentication weaknesses
  • Wireless Network Testing - Assessment of Wi-Fi security including encryption standards, rogue access point detection, and authentication mechanisms
  • Cloud Network Security - Testing of virtual networks, security groups, VPN tunnels, and cloud-to-on-premises connectivity
  • Network Segmentation Review - Verification that network segments properly isolate sensitive systems and prevent unauthorized lateral movement
Network security testing and infrastructure analysis

How We Secure Your Network

Our network security assessment follows a structured approach that covers every critical component of your infrastructure.

Phase 1: Network Mapping

We discover and map all network assets, services, and connections to build a complete picture of your infrastructure, including devices that may not be documented.

Phase 2: Vulnerability Discovery

We identify weaknesses across network devices, operating systems, services, and protocols using both automated scanning and manual analysis techniques.

Phase 3: Exploitation Testing

We attempt controlled exploitation of identified vulnerabilities to validate their severity and demonstrate the real-world impact of each finding on your network.

Phase 4: Lateral Movement Analysis

After gaining initial access, we test how far an attacker could move within your network, identifying segmentation failures and privilege escalation paths.

Phase 5: Reporting and Hardening

We deliver a detailed report with network diagrams, attack paths, severity ratings, and specific hardening recommendations for each identified vulnerability.

Why Codesecure for Network Security

  • Deep Infrastructure Knowledge - Our team has hands-on experience with enterprise routers, switches, firewalls, load balancers, and complex network topologies
  • Internal and External Testing - We test from both outside your perimeter and within your internal network to simulate different attacker scenarios
  • Attack Path Visualization - Our reports include clear diagrams showing how an attacker could chain multiple weaknesses to reach critical assets
  • Configuration-Level Fixes - Remediation guidance includes specific configuration commands and policy changes for your network devices
  • Segmentation Validation - We verify that your network zones properly isolate critical systems like payment processing, databases, and management networks
  • Free Retesting Included - After your team implements fixes, we retest to confirm vulnerabilities are properly resolved

Compliance Standards Our Network Testing Supports

Network security testing is a core requirement across major compliance frameworks. Our assessments help you meet and maintain these standards.

ISO 27001

Network security testing validates Annex A controls related to network access control, segregation, and secure communication channels.

PCI DSS

Our network testing addresses PCI DSS requirements for network segmentation, firewall management, and regular penetration testing of cardholder data environments.

SOC 2

Network security assessments provide evidence for SOC 2 criteria related to logical access controls, system boundaries, and infrastructure security.

HIPAA

Our testing validates network-level technical safeguards protecting electronic protected health information from unauthorized access and interception.

DPDP Act

Network security testing ensures that the infrastructure transmitting and storing personal data meets the protection requirements under India's DPDP Act.

RBI Guidelines

Our assessments address RBI cybersecurity framework requirements for network security controls, segmentation, and regular infrastructure testing.

Frequently Asked Questions About Network Security

A network security assessment includes external and internal network scanning, firewall rule analysis, network segmentation testing, wireless security evaluation, Active Directory review, and manual penetration testing to identify exploitable paths across your infrastructure.

We use controlled testing techniques with predefined rules of engagement. Testing windows are scheduled during low-traffic periods, and we coordinate with your IT team throughout the assessment to ensure business continuity is maintained.

Yes, we test on-premises networks, cloud environments (AWS, Azure, GCP), and hybrid architectures. Our testing covers VPNs, virtual networks, cloud security groups, and the interconnections between your on-premises and cloud infrastructure.

We test for unauthorized access paths, lateral movement opportunities, man-in-the-middle attack vectors, DNS poisoning, ARP spoofing, VLAN hopping, privilege escalation through network services, and weak authentication in network devices.

We recommend network security testing at least annually, after major infrastructure changes, when adding new network segments, and after deploying new network devices or services. Organizations in regulated industries may require more frequent testing.
