Network Infrastructure Audit / VAPT

Internal and external network penetration testing covering firewalls, routers, switches, VPNs, AD and servers. Aligned with NIST SP 800-115 and CIS benchmarks, delivered by OSCP and OSEP-certified consultants.

Automated + manual testing 1-2 week delivery (by size) Starts from INR 30K Instant response, no delay Free retest included

At a Glance

  • Engagement type: Internal + external network penetration testing
  • Coverage: Firewalls, routers, switches, VPN, AD, servers, segmentation, lateral movement
  • Typical duration: 1-2 weeks total, based on network size and host count
  • Starts from INR 30,000: fixed price scoped after a free 30-minute call
  • Response time: instant, no delay. We start same day or next business day after scoping

What is It?

A network infrastructure audit is a comprehensive penetration test of your internal and external network surface. We test firewall rules, network segmentation, Active Directory, VPN, exposed services and lateral movement paths from compromised footholds.

Codesecure's network VAPT is delivered by OSCP and OSEP-certified consultants under signed NDA. Every engagement follows PTES and NIST SP 800-115, with output mapped to CIS benchmarks plus your compliance frameworks. Both external (internet-facing) and internal (assumed-breach) perspectives covered.

Why It Matters

Network is the path attackers take from initial foothold to crown jewels. The 2025 Verizon DBIR shows 60%+ of breaches involve lateral movement through internal networks once initial access is achieved. Flat networks, weak segmentation and misconfigured AD remain the top enablers.

For Indian enterprises, especially banks, NBFCs and manufacturers, RBI Cyber Security Framework and ISO 27001 Annex A.8.20-8.22 require demonstrated network security testing. Regulators increasingly examine penetration test findings and remediation evidence during supervisory visits.

What We Test

Comprehensive coverage of the most exploitable risk categories for this service:

External PerimeterInternet-exposed services, edge device vulnerabilities, exposed VPN, RDP, SSH
Firewall & RulesACL review, NAT policies, segmentation bypass, vendor-specific issues
Active DirectoryKerberoasting, ASREPRoasting, Pass-the-Hash, GPO misconfigurations, delegation abuse
Network SegmentationVLAN hopping, inter-zone access controls, OT/IT separation, DMZ enforcement
VPN & Remote AccessAuthentication bypass, split tunneling, credential abuse, ZTNA evaluation
Lateral MovementPivot paths from compromised endpoints to crown jewels, privilege escalation chains
Services & ProtocolsSMB, LDAP, SNMP, DNS, NTP, weak protocols, insecure defaults
Wireless NetworksWPA2/3 testing, rogue AP detection, guest network isolation, 802.1X bypass
IDS/IPS EvasionDetection capability validation, signature gaps, alerting effectiveness
Patch & ConfigurationMissing critical patches, misconfigured services, weak baselines

Our Methodology

Every engagement follows a 5-phase methodology aligned with PTES, NIST SP 800-115 and OWASP testing guides:

1

Scoping & Reconnaissance

Free scoping call, signed NDA, fixed-price proposal in 24-48 hours. Asset discovery, OSINT, attack surface mapping.

2

Threat Modeling

Targeted threat models against OWASP, MITRE ATT&CK, your specific business logic and applicable compliance frameworks.

3

Automated & Manual Testing

External + internal network testing using Nmap, Nessus, Metasploit, Cobalt Strike, BloodHound, custom tooling, plus deep manual exploitation by OSCP/OSEP-certified consultants. Real attack-path demonstration, not just scanner findings.

4

Reporting & Walkthrough

Executive summary plus technical report mapped to OWASP, CVSS v3.1 and your compliance frameworks. Live walkthrough with your engineering team.

5

Retest & Sign-Off

Free retest of all critical and high findings within 30 days. Formal sign-off letter and certificate. Customer data deleted 90 days after sign-off.

Frequently Asked Questions

Do you test from both inside and outside our network?

Yes. External testing covers the perimeter (internet-facing services, edge devices); internal testing covers assumed-breach scenarios from inside the network. Most engagements include both for complete coverage; some clients add a red team scenario.

Do you need physical access for internal testing?

Not typically. Internal testing can be done via VPN access to a jumpbox, a deployed pentest VM, or a small hardware appliance we ship. Physical onsite testing is available for specific scenarios (wireless, physical security).

How long does a network engagement take?

Most networks complete in 1-2 weeks. Small networks under 100 hosts: 5-7 days; mid-size networks (100-500 hosts): 10-12 days; enterprise networks may extend to 3+ weeks. We respond instantly, testing starts same/next business day after scoping.

What does it cost in INR?

Pricing starts from INR 30,000 and varies by host count, external IP range, AD complexity and number of physical sites. Fixed price after free 30-minute scoping call.

How quickly can you start?

Instant response, no delay. Response within an hour during business hours, fixed-price proposal within 24-48 hours under signed NDA, active testing starts same/next business day after sign-off.

Will this affect production network performance?

We coordinate carefully on intensity and timing. Vulnerability scanning is typically done off-hours or with throttling; manual exploitation rarely affects performance. We have never caused a production outage on a properly scoped engagement.

Do you provide a network red team option?

Yes, as a separate engagement. Red team simulates a determined attacker over 4-8 weeks with limited scoping disclosure to defenders. Quoted separately from standard network VAPT.
