Network Penetration Testing Services

Network penetration testing evaluates the security of an organization’s infrastructure by simulating how attackers attempt to gain unauthorized access to systems and move through internal networks.

These tests help identify weaknesses in network architecture, authentication controls, segmentation policies, and exposed services.

External Network Penetration Testing

External network testing focuses on internet-facing systems such as web servers, VPN gateways, firewalls, and remote access portals.

This type of penetration test answers critical questions like:

  • Could an attacker gain access to our environment from the internet?
  • Are exposed services properly secured?
  • Are there exploitable vulnerabilities in public-facing infrastructure?

External testing is often the first step in identifying real-world attack vectors.

Internal Network Penetration Testing

Internal penetration testing assumes an attacker has already gained initial access to the environment—often through compromised credentials, phishing attacks, or insider threats.

The goal is to determine how far an attacker could move within the network.

This testing evaluates:

  • Active Directory security
  • Privilege escalation vulnerabilities
  • Lateral movement pathways
  • Access to sensitive systems and data

Internal network testing often reveals weaknesses that traditional vulnerability scans miss.

Network Segmentation Testing (PCI)

For organizations that process payment card data or must meet PCI DSS requirements, network segmentation testing validates whether sensitive cardholder environments are properly isolated from the rest of the network.

This testing ensures segmentation controls effectively prevent unauthorized access to regulated systems.

ICS & SCADA Penetration Testing

ICS and SCADA systems control critical infrastructure in industries like manufacturing, energy, utilities, and transportation. Because these systems manage real-world operations, security vulnerabilities can disrupt production and create serious safety and operational risks.

ICS and SCADA penetration testing evaluates the security of industrial networks and control systems to identify weaknesses that attackers could exploit. uMercs safely assesses components such as industrial devices, network segmentation, remote access systems, and industrial communication protocols.

This testing helps organizations protect critical systems, strengthen operational technology (OT) security, and reduce the risk of cyber incidents that could impact physical operations.

Application and Cloud Security Testing

Modern organizations rely heavily on web applications, APIs, and cloud platforms. These technologies expand the attack surface significantly and require specialized security testing.

Web Application Penetration Testing

Web applications are one of the most common targets for cyberattacks.

Our web application penetration testing identifies vulnerabilities such as:

  • SQL injection
  • Cross-site scripting (XSS)
  • Authentication flaws
  • API vulnerabilities
  • Session management weaknesses

Testing is performed using both manual techniques and automated tools to ensure thorough coverage.

Mobile Application Penetration Testing

Mobile apps often handle sensitive data and connect directly to backend systems, making them a common target for attackers. Mobile application penetration testing evaluates the security of iOS and Android apps to identify vulnerabilities that could expose data, user accounts, or business systems.

uMercs tests mobile applications for issues such as insecure data storage, weak authentication, API vulnerabilities, improper encryption, and insecure communications between the app and backend services.

This testing helps organizations protect user data, secure mobile platforms, and ensure their applications are resilient against real-world cyber threats.

Cloud-Based Penetration Testing

Cloud environments introduce unique security challenges due to shared infrastructure, misconfigurations, and identity management complexity.

Our cloud penetration testing evaluates security across major cloud platforms such as:

  • AWS
  • Microsoft Azure
  • Google Cloud

Testing focuses on cloud architecture, access controls, misconfigured storage, and identity privileges.

Cloud Configuration Security Assessment

Misconfigured cloud environments are responsible for a large percentage of modern data breaches.

Our cloud configuration assessments identify:

  • Over-permissioned IAM roles
  • Publicly exposed storage
  • Misconfigured network policies
  • Insecure cloud services

These assessments help organizations strengthen their cloud security posture before attackers discover configuration errors.

Wireless and Human Attack Surface Testing

Not all cyber threats originate from software vulnerabilities. Attackers frequently exploit human behavior and wireless networks to gain access.

Wireless Penetration Testing

Wireless networks can expose organizations to unauthorized access if they are improperly configured.

Wireless security testing identifies vulnerabilities such as:

  • Weak encryption protocols
  • Rogue access points
  • Poor network segmentation
  • Unauthorized wireless devices

This testing ensures wireless infrastructure does not become an entry point for attackers.

Social Engineering Testing

Human error remains one of the most common causes of security breaches.

uMercs provides multiple social engineering testing services designed to evaluate how employees respond to real-world attack scenarios.

Email Phishing Simulation

Phishing testing simulates malicious emails designed to trick employees into revealing credentials or clicking malicious links.

Vishing (Voice Phishing)

Phone-based social engineering attempts to manipulate employees into providing sensitive information or granting access to systems.

These tests help organizations measure employee susceptibility to social engineering attacks and improve security awareness.

Artificial Intelligence Security Testing

As organizations begin deploying AI systems, the attack surface continues to expand.

AI Penetration Testing

AI systems introduce new vulnerabilities related to data poisoning, prompt injection, model manipulation, and adversarial inputs.

Our AI penetration testing evaluates how AI-driven systems respond to malicious inputs and whether attackers could manipulate system behavior.
