Network Penetration
Testing

We go beyond surface-level assessments by performing a comprehensive penetration test of your network infrastructure.

We provide a clear risk classification framework

We don’t just identify weaknesses-we actively test how they can be exploited under controlled, ethical conditions. This enables us to determine the actual level of risk to your organization and establish whether critical assets are truly exposed.

Our network penetration testing service found vulnerabilities

The technology industry thrives on innovation, agility, and seamless digital transformation. At CyberZEALS, we empower tech-driven businesses with advanced IT solutions.

Identify and rectify insecure configurations that expose your network to vulnerabilities.

Detect and secure sensitive credentials that may lead to unauthorized access.

Assess and strengthen firewall rules to prevent unauthorized network traffic and attacks.4

Types of network penetration testing

Network penetration testing, also referred to as infrastructure penetration testing, can be carried out from two key perspectives:

Internal penetration testing

The purpose of an internal network penetration test is to assess what an attacker might do after gaining initial access to your internal systems.

This kind of evaluation simulates possible insider threats, such as situations in which staff members take detrimental acts within the network due to carelessness or malevolent intent.

External penetration testing

An external network penetration test simulates actual external attacks to assess the effectiveness of your perimeter defences.

In addition to finding vulnerabilities in internet-facing assets like web servers, mail servers, FTP services, etc., the objective is to ascertain how well your security policies can prevent and detect intrusions.

How We Do Infrastructure Penetration Testing

Our network penetration tests at CyberZEALS are conducted utilising a tried-and-true, systematic process intended to find vulnerabilities, try controlled exploitation, and offer helpful remedial advice.

Scoping

Together, you and our network and infrastructure security experts determine which assets, networks, and systems will be part of the evaluation. In this phase, we collaborate closely with your team to set specific goals and create a customised assessment plan that fits your security priorities and business needs.

Information Gathering & Reconnaissance

To find possible attack surfaces, we acquire a lot of intelligence. This involves looking for open ports, active services, vulnerable apps, and publicly accessible data that hackers could use to target your company.

Vulnerability Identification

We examine internet-facing systems using both automated and manual methods to find vulnerabilities like out-of-date software, incorrect setups, inadequate encryption, and authentication issues.

Exploitation (Controlled Testing)

Our ethical hackers try safe, controlled exploitation to verify the hazards after vulnerabilities are found. This step mimics how actual attackers might utilise the vulnerabilities found to obtain unauthorised access or interfere with operations without harming your systems.

Post-Exploitation Analysis

By examining what information or systems could be accessed and how far an attacker could travel inside your environment, we determine the possible consequences of a successful attack. This makes it easier to rank remediation according on business risk rather than just technical seriousness.

Reporting & Remediation Guidance

The last phase produces a concise, comprehensive report detailing: Every vulnerability found and the risks they pose The probability and consequences of effective exploitation Environment-specific business effect analysis Remedial recommendations that are practical and prioritised for your IT and security teams

Frequently Asked Questions

What is the purpose of a network penetration test?

The goal of a network penetration test is to identify security weaknesses in your internal or external network before attackers do. It shows how easily a hacker could break in, what data they could access, and what steps you need to take to fix vulnerabilities.

Can an internal pen test be performed remotely?

Yes, internal penetration tests can often be carried out remotely using secure VPN access or virtual machines. However, some organizations prefer on-site testing to simulate insider threats more accurately.

How are pen test findings reported?

After the test, you receive a detailed report that explains:

The vulnerabilities discovered
The risk level of each issue
Evidence of exploitation (if successful)

What is the difference between internal pen testing and external pen testing?

Internal pen testing simulates an attack from inside your network (like a malicious insider or someone who already bypassed perimeter defenses).
External pen testing focuses on your public-facing systems (like websites, firewalls, and VPNs) to see if outsiders can break in. Both are critical for full protection.

What information is required to scope a network penetration test?

To properly scope a network pen test, we need details like:

The number of IP addresses or systems to test
The type of environment (on-premises, cloud, or hybrid)
The depth of testing required (internal, external, or both)
