Overview

What is Network Penetration Testing?

Network Penetration Testing (NPT) is the process of evaluating your internal and external network infrastructure to identify vulnerabilities, security weaknesses, and misconfigurations that could be exploited by malicious actors. These networks serve as the backbone for your most critical business operations — making them a top target for cybercriminals.

CyberHunt IT Solutions provides intelligent, proactive, and scalable cyber defense solutions using a combination of manual expertise and advanced scanning methodologies. We help organisations identify threats in routers, switches, firewalls, and servers before they escalate into damaging cyber incidents.

Our Approach to Network Penetration Testing

Reconnaissance
Scanning
Exploitation
Post Exploitation
Reporting
🔍

Reconnaissance & Information Gathering

Reconnaissance is an Information Gathering phase designed to map the external and internal attack surface of your network. It involves step-by-step processes of revealing valuable information about your infrastructure from existing sources — including IP block enumeration, open ports, routing information, and exposed services.

Our approach helps you understand how your network perimeter looks to an external attacker and what internal components are immediately visible to a rogue device — a critical foundation for a complete security assessment.

Vulnerability Scanning & Assessment

We perform both automated and manual scanning across your entire network environment — probing routers, switches, firewalls, and servers — using industry-standard tools combined with our proprietary methodology.

Every finding is manually verified to eliminate false positives, with severity ratings assigned per CVSS standards. We look for unpatched software, weak encryption protocols, default credentials, and configuration flaws.

Exploitation & Impact Analysis

Controlled exploitation of confirmed vulnerabilities is performed to assess the real-world business impact. We demonstrate how an attacker could leverage exposed services, weak authentication, or misconfigured network devices to compromise the network segment.

All exploitation is performed safely within the agreed scope, providing full evidence capture including screenshots and proof-of-concept demonstrations of unauthorized access.

Post-Exploitation & Lateral Movement

After gaining initial access to a device or network segment, we evaluate lateral movement opportunities, privilege escalation paths, and potential data exfiltration scenarios. This determines the maximum damage potential an attacker could achieve after breaching your perimeter.

We assess Active Directory weaknesses, internal trust relationships, routing protocol flaws, and the ability to chain multiple lower-severity issues into critical network-wide compromise.

Reporting & Remediation Guidance

A comprehensive Network VAPT report is delivered within 48 hours of assessment completion. The report includes an executive summary for management, a detailed technical breakdown for network administrators, CVSS-scored findings, step-by-step reproduction steps, and actionable remediation recommendations.

A free re-test is included after fixes are applied — ensuring your network remediation was effective and your environment is secure.

Testing Types

Network Security Assessment Types

Choose the testing approach that matches your requirements and risk profile

External / Black Box Testing

Black Box
Testing

Zero-knowledge testing that simulates an external attacker trying to breach your network perimeter over the Internet. We test firewalls, exposed servers, and VPN endpoints to identify vulnerabilities visible to the outside world.

  • External attacker simulation
  • No prior network knowledge
  • Tests internet-facing attack surface
  • Real-world breach scenario
Internal / Grey Box Testing

Grey Box
Testing

Simulates an attack from the perspective of an insider threat or an attacker who has already breached the perimeter. Tests internal network segmentation, Active Directory security, and internal system vulnerabilities.

  • Internal network perspective
  • Simulates malicious employee/malware
  • Assesses lateral movement risks
  • Most common engagement type
White Box / Architecture Review

White Box Testing

Full-knowledge testing with access to network diagrams, routing configurations, and firewall rulesets. Provides the most thorough coverage — uncovering configuration flaws, insecure routing protocols, and vulnerabilities hidden by complex network layers. Ideal for compliance audits and new infrastructure deployments.

  • Firewall rule review
  • Router & switch configuration analysis
  • In-depth network design flaw analysis
  • Compliance-ready documentation
Why It Matters

Benefits of Network Security Testing

Secure Network Infrastructure

Identify vulnerabilities in routers, switches, and firewalls that could compromise your entire corporate environment before attackers do.

Ensure Compliance

Meet strict PCI-DSS, ISO 27001, HIPAA, and SOC 2 regulatory compliance requirements with documented, certified security testing evidence.

Prevent Ransomware & Breaches

Proactively lock down internal spread vectors and close external entry points to prevent devastating ransomware infections.

Maintain Business Continuity

Ensure critical network services remain available by mitigating DoS risks and protecting infrastructure from malicious disruptions.

Common Questions

Frequently Asked Questions

What is meant by network penetration testing?
Network penetration testing is the process of evaluating an organisation's network infrastructure (both internal and external) to identify vulnerabilities, weaknesses, and misconfigurations. It simulates real-world cyberattacks to uncover risks in firewalls, routers, servers, and endpoints, helping organizations prevent data breaches and maintain a secure perimeter.
What are the main approaches to network security tests?
The primary approaches to network security testing include Black Box Testing (External testing with no prior knowledge to simulate an outside hacker), Grey Box Testing (Internal testing simulating an insider threat or compromised workstation), and White Box Testing (Full architecture and configuration reviews for maximum depth).
How long does a network penetration test take?
The duration depends heavily on the scope, specifically the number of live IP addresses and the complexity of the network. A standard network VAPT typically takes 3–7 business days for testing, with the detailed report delivered within 48 hours of assessment completion. Large corporate networks may require 10–15 days for comprehensive coverage.
What factors decide the timeline of a Network VAPT?
Network VAPT timelines depend on the total number of internal and external IP addresses, the number of active network devices (routers, switches, firewalls), physical locations, and whether the testing includes wireless networks or Active Directory exploitation. We define a clear timeline during the initial scoping call.
What is the methodology for network security testing?
Our approach follows a structured framework aligned with PTES and NIST SP 800-115: (1) Reconnaissance & OSINT, (2) Port & Vulnerability Scanning, (3) Exploitation, (4) Post-Exploitation & Lateral Movement, and (5) Detailed Reporting with Remediation Guidance.
Will our network experience downtime during testing?
No. Our network security assessments are conducted carefully using controlled exploitation techniques to ensure there is no service disruption. Testing is coordinated with your IT team during agreed maintenance windows if necessary, and we avoid performing any destructive actions (like DoS attacks) without your explicit written consent.
