What is penetration testing?
Penetration testing is a simulation of a real cyberattack. It involves a systematic evaluation process that uncovers vulnerabilities in your people, systems, or processes.
Your ultimate guide to different types of penetration testing
Before you decide on the perfect provider, it’s essential to understand the various types of pentesting. Each of them focuses on specific aspects of security evaluation. They can vary in what they concentrate on, how deep they go, and how long they take. Let’s explore this topic to help you make the best choice for your needs.
1.Network penetration testing (internal and external)
This type of pentesting involves internal and external assessment of an organization’s network infrastructure for vulnerabilities and security weaknesses. Experts simulate real-life attacks to identify probable entry points that cybercriminals could exploit. They analyze network architecture, configurations, and devices to help you discover misconfigurations, open ports, weak authentication mechanisms, and other access points.
The process involves:
- Passive and active scanning
- Vulnerability assessment
- Attempts to exploit identified vulnerabilities
- Lateral movement to access all parts of the network
- Post-exploitation to show the impact of found vulnerabilities
The goal is to provide insights into potential risks, prioritize remediation efforts, and enhance the network’s security posture.
Who needs network penetration testing?
Any entity relying on computer networks can benefit from this type of pentest: government agencies, financial institutions, healthcare providers, tech companies, critical infrastructure, and service providers.
2. Wireless penetration testing
This service aims to uncover vulnerabilities of wireless networks that malicious actors could use to access your digital ecosystem. It may involve attempts to bypass authentication mechanisms, gain unauthorized access to a network system, or intercept sensitive data. By emulating potential threat vectors, testers can pinpoint areas where defenses are weak.
Who needs wireless penetration testing?
Any organization using wireless networks should perform such tests to protect data and prevent unauthorized access.
3. Mobile penetration testing

5. Social engineering campaign
Even with the latest firewalls, antivirus, and other security measures, businesses still remain vulnerable. Why? Because in most cases the weakest link in the entire security chain is not technology but the employees.
Social engineering involves manipulating or deceiving individuals to gain unauthorized access to sensitive information or systems. Attackers exploit human psychology and various tactics, such as phishing emails, text messages, and even AI technologies for Deepfake and Voice Synthesis.
Ethical hackers conduct social engineering campaigns where they collect valuable information to create customized scenarios. They maintain a flexible approach that adjusts to emerging social engineering tactics like spear-phishing, pretexting, and vishing. The aim is to help clients identify vulnerabilities, bolster employee resilience, and reduce susceptibility to social engineering attacks.
Who needs social engineering penetration testing?
It is crucial for all businesses, no matter how much an organization invests in hardware and software security. A social engineering campaign will help assess human risk as an attack vector in your company.
6. Cloud penetration testing
During this type of penetration testing, experts perform cyberattacks on your cloud infrastructure and assess configurations to discover weaknesses and possible entry points.
As cloud providers implement a shared responsibility model, testers focus on the vulnerabilities that are part of the client’s obligation. While the cloud service provider accounts for the security of hardware, network, and cross-tenant access, clients are responsible for the code and data security they deploy. Depending on the chosen cloud platform, security engineers will examine the setup for particular misconfigurations associated with that provider’s environment.
Who needs cloud penetration testing?
It is crucial for businesses utilizing cloud services: AWS S3 buckets for storage, GCP Compute engine for virtual machines, AWS Lambda for serverless applications, Microsoft Entra ID (prior Azure AD) for identity management, and more.
7. IoT penetration testing
This type of pentesting evaluates Internet of Things (IoT) devices for security vulnerabilities and existing misconfigurations. Its goal is to detect weaknesses and suggest realistic safeguards that will not disrupt business processes or require device reengineering.
This service involves simulating attacks on IoT devices and communication protocols to check each chip/component for known vulnerabilities, such as side-channel attacks, memory leaks, power glitching, etc. It helps to ensure the hardware design is security-focused. In terms of software, penetration testers will examine communication protocol gaps, including but not limited to Wi-Fi, Bluetooth, RFID, ZigBee, Modbus, or other custom-made protocols.
Who needs IoT penetration testing?
IoT penetration testing is critical for businesses and industries relying on IoT (e.g., smart devices, industrial automation, ICS/SCADA systems) to ensure data protection and prevent unauthorized access.
8. Red team attack simulation
Red teaming is a comprehensive and structured cybersecurity assessment approach designed to uncover vulnerabilities and weaknesses within an organization’s overall security posture. It goes beyond traditional penetration testing by simulating sophisticated and persistent cyberattacks that mimic the tactics, techniques, and procedures (TTPs) employed by real adversaries. Red teaming can also help organizations comply with regulatory requirements and strengthen their overall security posture.
Who needs a red team attack simulation?
It is valuable for organizations that require a thorough evaluation of security measures, especially those in high-stakes industries like finance, healthcare, government, and critical infrastructure.
The average cost of a data breach exceeds $3.8M.

The most popular approaches to penetration testing
Apart from penetration test types, there are three fundamental approaches to penetration testing, including:
Black box (zero knowledge)
It is a simulation of an external cyberattack on a company’s domain or application environment. Ethical hackers have limited information, typically just the link to the target system. The objective of black box penetration testing is to identify vulnerabilities and potential entry points solely based on external-facing components.
Pentesters utilize various tools, techniques, and methodologies the attacker could use. They perform reconnaissance, scanning, vulnerability assessment, and exploitation attempts.
The advantage of black box testing is that it provides an unbiased assessment from an outsider’s perspective, mimicking real-world attack scenarios.
Gray box (basic knowledge)
This approach involves starting the assessment with a certain level of access already granted. This information is typically provided by the client or obtained through limited access to the system. The level of shared information may vary, but testers usually have access to some documentation, login credentials, or network schemes.
The goal of this testing methodology is to emulate the actions of a motivated attacker who has obtained a minimum level of access. By adopting this perspective, the pentest team can uncover vulnerabilities that may have been overlooked during regular security assessments.
White box (full knowledge)
During such assessments, penetration testers have complete internal visibility, including access to the system’s functionality, architecture, configuration, and implementation details. They also have access to the application’s source code, database schemas, system documentation, and other relevant information.
Ethical hackers can perform activities such as code review, static and dynamic analysis, configuration review, and architecture assessment. By having complete visibility into the system, they can identify weaknesses that may not be apparent from an external perspective.
As you can see, various types of penetration tests serve specific purposes. Choosing the most suitable one for your needs can be challenging. To provide clarity and assist you in making an informed decision, we’ve created a comparison table based on our clients’ most common requests.
