10 Types Of Penetration Testing: A Comprehensive Guide in 2025

A huge number of organizations will counsel penetration testing if they have an extensive cybersecurity strategy. Penetration testing usually includes an authorized and then controlled attack to value the security of computer systems, networks, applications, and their respective infrastructure for vulnerabilities that an attacker might use against internal systems to compromise their systems for confidentiality, integrity, or availability. This blog post will review, the types of pen testing across applications and networks through social engineering, IoT, and cloud penetration testing. This will cover key requirements in different domains and mention a few commonly used methodologies and frameworks. What are the Different Types of Pen Testing? Here are the various types of penetration testing:   Network Penetration Testing A network penetration test is required for any business or organization to assess the state of security of its network infrastructure by identifying vulnerabilities that can be exploited by threat actors (hackers) out of malicious intent. Such pen testing can include testing external, internal, and wireless network penetration. To a great extent, internet / external penetration testing is typically performed to discover whether and how an attacker from outside can break into a company network, primarily focusing on firewall attack vector tests or router pen tests. On the opposite ground, internal network penetration testing checks an organization’s internal infrastructure including servers, workstations, and network devices for intramural vulnerabilities abused by insider threats or unauthorized intruders who gain access to the internal network. Finally, wireless network pen tests assess the security of wireless networks and Wi-Fi and Bluetooth-connected devices within an organization to identify weaknesses exploited by attackers seeking unauthorized access or eavesdropping on wireless communications. Paid: Nmap Web Application Penetration Testing Web application pen testing is among the most common types of penetration tests wherein such applications are evaluated for their security through simulated attacks to identify vulnerabilities. Most typically seen in black-box, white-box, and grey-box testing, in which numerous aspects of information are available to the penetration tester. Whereas black-box testing is done without any knowledge of the application architecture, white-box testing allows a tester complete access to source code and other relevant information. The grey-box method is a compromise between the two, in which the tester has some knowledge of application internals. Paid: Open Source: API Penetration Testing API penetration testing is a technique for penetration testing of APIs to detect vulnerability existences in an organization/API, thus simulating attacks on them by a hacker. Since the API continues playing a major role in integrating other heterogeneous applications and services, it has now become the darling of a hacker craving unauthorized access to core functionality and data. Paid: Open Source: Mobile Application Penetration Testing Mobile Application Penetration Testing is a type of pen testing approach used to assess the security of mobile programs for various platforms, like Android, iOS, and Windows, which might be not typical. With the drastic increase in mobile applications and the sensitive user information and critical functions they handle, it is only natural that today, security risks (whether noticed or not) have increased. The iOS application testing audits ensure the security of Apple’s mobile-side developments, which is more focused on security and best practices. They also test the application’s data storage, communication protocol, and logging aspects. Android application testing is concerned with applications developed for Google’s mobile operating system. Since Android has a higher market share, it is more attractive to hackers. Common Mobile App Vulnerabilities found in Penetration Testing include: Paid: Open Source: Cloud Penetration Testing Cloud penetration testing development is, as is evident now, an important process wherein one assesses the security level of a certain enterprise cloud infrastructure and services, as companies now need to move to cloud infrastructures. As there are higher numbers of enterprises migrating to the cloud, the need to mitigate the vulnerabilities and weaknesses that attackers can exploit is reinforced. Cloud penetration tests can be classified into 3 categories:  IaaS, PaaS, and SaaS. Paid: Open Source: Social Engineering Penetration Testing Social engineering (SE) is another form of penetration testing that examines an enterprise’s human-based attack surface to prepare and educate its employees to detect and counter-attacks, including how to trick individuals into disclosing confidential information or performing activities that violate security procedures. This allows companies to be able to observe their weaknesses in educating their staff about security and threats. Phishing is one of the common techniques applied using SE, though attacks usually arise in phishing since these take forms like messages and emails where respectability and reputable companies appear with requests for divulging such vital information like banks’ information and passwords. Open Source: IoT Penetration Testing IoT (Internet of Things) penetration testing assesses the relationship between security and connected devices in company-specific infrastructure. The IoT penetration testing is based on security testing of the different types of layers such as: Open Source:   Latest Penetration Testing Report Download Red Teaming vs. Penetration Testing: Key Differences Red teaming and penetration testing are the breaches and tests; organizations may utilize them as security assessments in determining their posture in cybersecurity assessment. Despite both methodologies searching for vulnerabilities, they have different natures, objectives, and means of execution.  Understanding the types of pen testing helps organizations choose the right approach for their security needs. Red teaming, the simulation of attacks of a real-world adversary, is a far more involved testing of the organization’s capabilities to detect and respond to these attacks. It gives a very comprehensive picture of an issuer’s security status in the face of advanced persistent threats. Penetration testing, on the other hand, is a focused, technical evaluation of the organization’s systems, networks, and applications. Aspect Red Teaming Penetration Testing Scope & Objectives Broad scope assesses overall security posture & resilience Narrow scope, focuses on specific vulnerabilities Duration & Depth Longer engagements, comprehensive & iterative Shorter engagements, focused & linear Attacker’s Perspective Adopts real-world attacker mindset & techniques Primarily focuses on technical vulnerabilities Detection & Response Tests the organization’s detection, response & recovery capabilities Mainly identifies vulnerabilities, not detection & response

Types of Penetration Testing – Black, White, and Grey box testing

With types of penetration testing, there is often a bit of confusion. Some say penetration testing types are black, white, and grey-box penetration testing. While others say application, network, cloud, API, and IoT penetration testing. Nevertheless, all of these are correct to some extent. The black, white, and grey box testing are mainly the approaches to penetration testing. The application, network, and cloud are the assets on which penetration testing is done. Regardless of the actual types, it is important to know that all types of penetration testing are conducted for one purpose only – to identify vulnerabilities and their impact. Organizations can choose to perform one or multiple types of pen testing (depending on their business and priority asset) to prevent cyberattacks. In this blog, we are going to discuss different types of penetration testing, why they are conducted, and how they differ from each other. What Exactly is Penetration Testing? Penetration testing, a.k.a pentesting or ethical hacking is the process of purposefully breaching a system’s security to find vulnerabilities. In most cases, both human and automated tools research, plan, and attack the given environment using various methods and channels. Once inside the environment, penetration testers will check exactly how deep they can get into it with the ultimate goal of achieving full access. While this process may sound weird, it’s a growing and important trend. Some of the biggest organizations around the world use this method to stay one step ahead of cybercriminals. By purposefully attacking your own application or network, you can discover security weaknesses before a hacker does and attempts a potential breach. Penetration Testing is Performed To: Who are Penetration Testers? Penetration testers or pen testers (a.k.a ethical hackers) are trained and certified in many technical and non-technical skills that allow them to ethically and professionally test clients’ digital assets. Unlike bug bounty testers, pen testers usually work full-time rather than as freelancers. Additionally, you can often see a specialized penetration testing team in cybersecurity companies, made up of different testers with different skill sets. Pen testers have a deep understanding of multiple programming languages, along with coding and network protocols. They are also armed with certain soft skills to complete assignments, for example critical thinking and creative problem-solving. Common Certifications of Pen Testers Include: Different Types of Penetration Testing – Areas Before selecting a suitable provider, you need to be familiar with the various types of penetration testing available, so that you can decide which one to choose. Each type of penetration test requires specific knowledge, methodologies, and tools to perform. Moreover, the goals could range from identifying flaws in the code to meeting regulatory compliance. 1. Application Penetration Testing It has two types – web application penetration testing and mobile application penetration testing. Web application penetration testing is assessing websites and custom applications to uncover flaws in the coding, design, and development that hackers could exploit. The penetration testers look for vulnerabilities like SQL injection, cross-site scripting (XSS), and encryption errors. Mobile app penetration testing is testing Android, iOS, and other OS mobile apps for authentication, authorization, data leakage, and session handling issues. It is done to check how secure mobile apps are against data theft and unauthorized access. 2. Network Penetration Testing Network penetration testing uses various ethical hacking techniques to identify any vulnerabilities present in the organization’s network and its security measures. If hackers successfully penetrate an organization’s network, they can get access to particularly any digital assets. The pen testers try to simulate real attacks to get behind the firewall of the network. They check for vulnerabilities like denial of service (DDoS) attacks, domain name systems (DNS), and SQL injection. Organizations use pentest reports to check whether their network infrastructure is strong enough to avoid cyberattacks.   Want to see a real penetration testing report?

Cloud Penetration Testing Cloud penetration testing examines the security of cloud-native services, configurations, cloud system passwords, cloud encryption, applications, APIs, databases, and storage access for potential vulnerabilities. After examining, the testers provide a report. It contains the vulnerabilities detected with actionable remediation steps. Companies then use this report to improve the security measures of their cloud infrastructure. Around 94% of companies use cloud services globally. As a result, it makes the cloud a prime target for cybercriminals. Cloud pentesting helps organizations: 4. API Penetration Testing API penetration testing means evaluating the security of an API of all types (REST, SOAP, and GraphQL) by simulating real attacks. It aims to identify all the vulnerabilities on the server side and in all the API’s components and functionalities. The API pentest report consists of all the vulnerabilities discovered, their impact level, and corrective measures. By conducting regular pen tests, organizations can then reduce security breaches and ensure the security of sensitive data present in the APIs. Additionally, it can ensure that the API is functioning the way it is intended to. Common API security threats include: 5. IoT Penetration Testing IoT penetration testing replicated real-world cyberattacks on Internet of Things (IoT) devices and networks to find security flaws. The techniques used in IoT pentesting include analyzing network traffic, exploiting vulnerabilities in IoT web interfaces, and reverse-engineering the device’s firmware. Since more organizations and individuals use IoT devices, penetration testing checks and help in strengthening the security of these devices from cyber criminals. IoT Penetration Testing can detect the following security threats: 6. AI/ML Penetration Testing AI/ML penetration testing involves evaluating the security of artificial intelligence and machine learning applications (such as ChatGPT). These systems, which often make critical decisions based on data, can be vulnerable to unique security threats. Penetration testing for AI/ML systems aims to identify and exploit weaknesses in the algorithms, data, and models used by these systems. Common tests include: By performing AI/ML penetration testing, organizations can understand the security flaws in their AI/ML systems and take steps to protect against potential threats. As a result, it helps

Importance of Security Penetration Testing for Businesses

One of the major risks businesses are facing worldwide is hackers exploiting vulnerabilities that exist in their IT infrastructure. As technology and interconnectivity are growing, the landscape of cyber threats is also growing. To avoid hackers getting inside your internal network and using it for their gain, businesses need to perform regular security penetration testing. Penetration testing is where cybersecurity professionals use a hacker-style approach to find vulnerabilities that could lead to various cyberattacks. Cybercrimes have increased a whopping 600% since the beginning of the pandemic, which is why 85% of the US and European organizations have increased their penetration testing budgets. In this blog, we will learn about security penetration testing, what are its types, and why it is important for businesses globally. What is Security Penetration Testing? Security penetration testing or pentesting is the process of strategically hacking into your system or network to identify as many vulnerabilities as possible. Cybersecurity professionals or ethical hackers perform these tests with the full authorization of the client. Penetration testers use various tools and techniques to test the security measures of your IT infrastructure and check weak points through which real hackers can enter. After the testing, they generate a report on the vulnerabilities they found and the steps to fix them. In fact, in some cases, they offer advice to the developers in the fixing process. Security testing services has been around since the 90s, but with the rise of connectivity recently, its need has grown exponentially. More and more businesses are conducting penetration testing as a major part of their cybersecurity.   Are you also worried about data breaches and hackers stealing your information?

With regular pen tests, you can reduce cyber risk, protect customer data, satisfy client/stakeholder requirements, comply with industry regulations, and maintain the organization’s image and reputation. Security vulnerability testing is is essential for identifying and addressing potential weaknesses before they can be exploited by malicious actors. Additionally, you should perform penetration testing if you: Suspect new security risks Develop or update a new company network or software Move your office or network, or relocate to a fully remote work environment Set up a new internal data storage location, or relocate existing data Were recently attacked by hackers Implement a new end-user policy or program   Benefits of Conducting Regular Security Penetration Testing As per a recent global survey, 93% of organizations have faced at least one data breach in the past 3 years. If this isn’t a reason to conduct penetration testing, here are a few compelling reasons: Identify Vulnerabilities before Hackers Hackers or cybercriminals are always looking for ways to get inside your system. In fact, if they find just one vulnerability in your security measures, they can use it for unauthorized access and data theft. Security vulnerability testing helps you discover these vulnerabilities before they get into the hands of a hacker. As a result, you can promptly fix them before any significant damage is done. Comply with Industry Standards Many industries have made it mandatory for businesses to conduct security testing to protect customer data. These regulations include HIPAA, PCI DSS, SOC 2, GDPR, etc. However, many businesses don’t comply with these regulations and face legal penalties with huge fines. By conducting penetration testing, organizations can achieve these compliances and avoid consequences. Meet Shareholders/Client Needs Recently, most shareholders and clients have been demanding security testing certificates before they conduct business with you. This is because they want to ensure that their data and information are safe with you. With a penetration testing certificate, you can assure them that you have successfully conducted security testing on your products or services and that it is safe to do business with you. Additionally, having a pentest certificate will also attract more leads and clients. Maintain Customer Trust and Reputation Customers are sharing their confidential information with your website, for example, personal and financial details, and expect it to be secure. With the pentest certificate, you can assure them that their data is safe, additionally attracting more customers. Once your business reputation is hampered, it is very difficult to gain the same trust. Even a single data breach or a small cyberattack can significantly damage your reputation in the industry. So, protect your business reputation by conducting regular cyber security penetration testing on your digital assets. Prevent Data Breaches and Financial Loss Hackers or cyber criminals who hack into your system mainly have two motives – steal sensitive data or finances. Every day some or other company is getting hacked and facing severe losses. Penetration testing will help you discover weak points through which hackers can enter your system.
