What is Network Penetration Testing?

Network penetration testing and security assessment is the structured process of identifying and exploiting vulnerabilities in your network infrastructure, including firewalls, routers, switches, VPNs, Active Directory, wireless networks and internet-facing services. A comprehensive network assessment covers both external attack surface (what an attacker can reach from the internet) and internal posture (what a compromised device or insider can access within your perimeter).

Codesecure delivers network security assessments under signed NDA with a fixed-price proposal within 48 hours. Our consultants hold OSCP, CEH and CISSP certifications and our ISMS is ISO/IEC 27001:2022 certified. Every finding is manually verified to eliminate false positives, CVSS v3.1 scored for prioritised remediation, and a free retest is included for all critical and high-severity network vulnerabilities after your team completes remediation.

Our Network Penetration Testing Services in Chennai

We cover every layer of your digital infrastructure, combining automated scanning with deep manual testing to deliver comprehensive security coverage:

External Network Penetration Testing Simulate real attacker techniques against internet-facing assets, perimeter firewalls, VPNs, DMZs and publicly exposed services
Internal Network Assessment Evaluate segmentation, lateral movement paths, privilege escalation routes and east-west traffic controls inside your corporate network
Firewall and Router Security Review Audit rule bases, ACLs, NAT configurations and routing protocols for permit-any rules, shadow rules and compliance violations
Active Directory Security Test AD for Kerberoasting, Pass-the-Hash, DCSync, delegation abuse and misconfigured GPOs that enable domain compromise
Wireless Security Testing Assess Wi-Fi networks for rogue APs, WPA2/3 weaknesses, PMKID attacks, captive portal bypasses and guest network isolation
VPN and Remote Access Review Evaluate SSL/IPSec VPN configurations, split-tunnelling, MFA enforcement and remote-desktop exposure for unauthorised access risks

Our Network Security Assessment Methodology

Every network and infrastructure engagement follows a 5-phase methodology aligned with PTES, NIST SP 800-115 and OSSTMM to systematically identify and validate vulnerabilities:

1

Reconnaissance and Asset Discovery

Passive and active discovery of internet-facing assets, internal subnets, domain infrastructure and network topology. OSINT, DNS enumeration, port scanning and banner grabbing to build a complete attack surface picture.

2

Vulnerability Identification

Automated scanning combined with manual analysis across all discovered hosts. Findings are verified to eliminate false positives and classified using CVSS v3.1 with network-specific exploitability context.

3

Exploitation and Lateral Movement

Controlled exploitation of confirmed vulnerabilities including privilege escalation, credential theft, Active Directory attacks and lateral movement to demonstrate real breach impact across network segments.

4

Reporting and Remediation Guidance

Executive summary with risk-ranked findings, detailed technical evidence, network topology diagrams and actionable remediation steps. Firewall rule recommendations and AD hardening guidance included.

5

Remediation Retest

Free retest of all critical and high-severity network findings after remediation. We confirm closure and issue a verification report for your ISO 27001 or PCI DSS audit evidence package.

Why Choose Codesecure for Network Penetration Testing in Chennai

Businesses across India and internationally trust us for network security because of the measurable difference in how we work:

ISO 27001:2022 Certified Our ISMS is independently certified. Consultants hold OSCP, CEH and CISSP. All network testing is conducted under strict rules of engagement with your IP ranges pre-authorised in writing.

Manual Testing, Not Just Scans Every vulnerability is manually verified and exploited where safe to do so. You get real attacker techniques, including lateral movement, credential theft and AD attacks, not scanner output.
Compliance-Ready Reports Reports map findings to ISO 27001, PCI DSS Requirement 11, NIST CSF, RBI IT Master Directions and DPDP Act. Accepted by auditors and enterprise procurement teams.
Free Retest Included After your team remediates critical and high findings, we retest at no extra cost and issue a remediation confirmation letter accepted by ISO 27001 and PCI DSS auditors.
Fixed Fee, No Surprises Fixed-price proposals within 48 hours of your free scoping call. The price covers all hosts in scope, with no per-host billing or surprise overages.

Compliance Frameworks Requiring Network Security Testing

Network penetration testing and infrastructure audits are required by multiple regulatory frameworks. Our reports are structured to provide the audit evidence each framework expects:

ISO 27001 A.8.8, Vulnerability Management

ISO 27001:2022 Annex A control A.8.8 requires systematic management of technical vulnerabilities. Regular network assessments and our reports satisfy this control requirement.

PCI DSS Requirement 11.3

PCI DSS v4.0 Requirement 11.3 mandates annual external and internal penetration testing for all in-scope network segments. Our reports meet all PCI DSS documentation requirements.

NIST CSF, Identify and Protect Functions

NIST Cybersecurity Framework Identify and Protect functions require asset management, network security and vulnerability management. Our network assessments support all five framework functions.

RBI IT Master Directions

RBI IT Master Directions mandate regular vulnerability assessment and penetration testing of network infrastructure for banks, NBFCs and payment aggregators in India.

DPDP Act 2023

India's Digital Personal Data Protection Act requires data fiduciaries to implement reasonable network security safeguards. Our network assessments identify exposures affecting personal data protection.

SOC 2 CC6, Logical and Physical Access

SOC 2 Trust Services Criteria CC6 requires logical access controls and network security monitoring. Network penetration testing provides technical evidence for CC6 control effectiveness.

Frequently Asked Questions

What is the difference between Vulnerability Assessment and Penetration Testing?

Vulnerability Assessment (VA) uses automated tools to systematically identify and catalogue known security weaknesses. Penetration Testing (PT) goes further: a consultant manually exploits those weaknesses, and others, to demonstrate real business impact. Network Pentest combines both to give you a complete picture of your security posture, from a broad scan to targeted attack simulation.

How often should Network Pentest be conducted?

At minimum once a year, and after any major infrastructure change, application release or new deployment. Internet-exposed applications handling customer or payment data should be tested quarterly. RBI-regulated entities (banks, NBFCs, payment aggregators) face more frequent requirements. Many organizations now run a continuous model with quarterly deep tests plus on-change validation.

What types of Network Pentest does Codesecure offer in Chennai?

We offer Web Application VAPT, Mobile App Security Testing (Android and iOS), API Security Audit, Network Penetration Testing (internal and external), Cloud Security Assessment (AWS, Azure, GCP), IoT Security Testing, Firewall Configuration Audit, Active Directory Security Audit and Thick Client Application Testing.

What standards does Codesecure follow for VAPT?
