What is Network Penetration Testing
Network Penetration Testing by Cyberous helps organizations identify security weaknesses within their internal and external network infrastructure. Our experts simulate real-world cyberattacks to uncover vulnerabilities in firewalls, routers, servers, and connected devices. Using a blend of automated tools and manual testing techniques, we assess network configurations, patch levels, and access controls to ensure complete protection. With Cyberous Network VAPT Services, businesses can detect potential threats, prevent unauthorized access, and strengthen their overall network security posture against evolving cyberattacks.
Network Penetration Testing Methodology
Network VAPT Methodology
The Network VAPT methodology at Cyberous combines advanced manual testing techniques with automated tools to simulate real-world cyberattacks and uncover hidden vulnerabilities. Aligned with PTES and NIST standards, our experts identify, validate, and prioritize critical security flaws while providing actionable remediation steps. With a regularly updated custom checklist and proprietary methods, Cyberous ensures comprehensive, reliable, and business-focused network security assessments that strengthen your organization’s defenses.
Scope Definition
Every Network Penetration Testing engagement at Cyberous begins with a clearly defined scope to ensure a precise, safe, and effective assessment. During this phase, our experts collaborate closely with clients to identify in-scope systems, network segments, and testing boundaries. For External Network Assessments, this includes relevant IP addresses, IP ranges, or IP pools, while for Internal Network Assessments, we establish secure VPN access or remote connections to simulate insider threats. Clients can also define sensitive or restricted assets that should not be scanned or exploited, ensuring safety and business alignment.
Information Gathering
After scope definition, Cyberous conducts comprehensive information gathering to map the in-scope network. Our experts enumerate open ports, identify running services, and profile the environment using techniques like banner grabbing, OS fingerprinting, and protocol identification. This detailed reconnaissance creates a precise blueprint for targeted vulnerability discovery and effective Network Penetration Testing.
Vulnerability Analysis
In the Vulnerability Analysis phase, Cyberous identifies and prioritizes security weaknesses across the network using manual techniques and automated tools. Our experts evaluate defenses against privilege escalation, intrusion attempts, and unauthorized access while detecting device-level misconfigurations that could expose your infrastructure to threats. This step ensures a clear understanding of risks for effective Network Penetration Testing.
Reporting
In the final stage of Network Penetration Testing, Cyberous delivers a clear and comprehensive report that includes an executive summary, detailed vulnerability findings with risk ratings, and step-by-step remediation guidance. Our goal is not just to identify risks but to provide practical, actionable solutions that help strengthen your network security posture and protect your organization against real-world cyber threats.

Black-Box Testing
Black-Box Testing
Black-Box Testing simulates a real-world external attack where the tester has no prior knowledge of the organization’s network, assessing how well your external security controls withstand genuine cyber threats.
At Cyberous, Black-Box Testing begins with detailed reconnaissance to identify open ports, exposed services, and publicly accessible assets. Our experts then attempt to exploit vulnerabilities in routers, firewalls, load balancers, and web servers to gain unauthorized access. The goal is to determine whether an attacker can breach the perimeter and how far they could move inside the network—providing clear insights to strengthen your external defenses.
Grey-Box Testing
Grey-Box Testing
Gray-Box Testing provides testers with partial knowledge of the network, allowing assessments that simulate insider threats or attackers who have limited access.
At Cyberous, our Gray-Box methodology delivers faster, more targeted assessments while still reflecting realistic attack scenarios. By analyzing specific network segments with informed precision, we uncover critical vulnerabilities and provide actionable insights to help organizations strengthen their defenses against both targeted attacks and insider-style threats.
White-Box Testing
White-Box Testing
White-Box Testing provides the most in-depth evaluation of network security by giving testers complete internal visibility into the environment.
At Cyberous, our White-Box assessment includes detailed reviews of network traffic, firewall and router rules, access controls, and configuration settings to identify flaws that could lead to privilege escalation, lateral movement, or internal compromise. With full transparency, vulnerabilities are uncovered faster and with greater accuracy, making White-Box Testing essential for strengthening internal network resilience and protecting against both insider misuse and persistent threats.
Frequently Asked Questions
Network Penetration Testing is a security assessment that identifies vulnerabilities in an organization’s internal and external network by simulating real-world cyberattacks.
It helps prevent data breaches, detects security gaps early, validates security controls, and strengthens your overall network security posture.
Cyberous examines open ports, services, firewalls, routers, access controls, misconfigurations, and potential attack paths using manual and automated techniques.
Organizations should conduct Network VAPT at least once a year or after major system changes, upgrades, or security incidents.
External testing simulates attacks from outside the organization, while internal testing evaluates risks from insiders or compromised devices within the network.
