The Best Penetration Testing Tools You Should Use In 2021

A penetration test, also known as a “pentest,” is a manual security evaluation of a business. A penetration security testing services provider will use one or more penetration testers to detect and fix bugs in its network setting. Normally, these engagements will include a series of targets that will be employed to assess the difference between an effective and failed evaluation.

Penetration checks of a system may be taken out for a number of purposes. A penetration test’s most basic goals include:

Creation of defenses: As organizations’ ecosystems change and cyber-attacks grow, current defenses can be insufficient to safeguard against new threats. Penetration monitoring presents useful information on what an entity can identify and defend against, as well as the ability to include or alter protections to improve their effectiveness.

Regulatory compliance: Certain data privacy laws mandate an organization to shield those sorts of confidential data from unauthorized access. These regulations can mandate a company to conduct periodic penetration testing to assure conformity, either directly or indirectly.

Security assessment: Companies require better cybersecurity to help protect their activities and clients, in addition to administrative enforcement. A penetration test assists in the detection of flaws and defects in a company’s cyber defenses.

The Types of Tools you’ll need to conduct a Good Pentest 

A penetration tester’s toolkit can incorporate a distinct set of tools, with the tools required varying depending on the specifics of the penetration testing engagement. Here are our cents on the types of pentest tools that can be employed in a variety of situations:

Port scanners: Port scanners identify available ports on a server, and may help determine the OS and applications of network connectivity that are actually operating on it. These machines are utilized for reconnaissance and to present information on possible attack vectors.

Vulnerability scanners: These scanners go a little farther than port scanners, trying to detect programs working on a device that have recognized bugs as well as any configuration errors. Vulnerability scanner results may help a penetration tester in determining which weakness to use for initial entry.

Network sniffer: A network sniffer receives and analyzes data streaming over a network for review. This enables a penetration tester to identify active programs on a network more subtly and see for exposed passwords or other private data streaming through the network.

Password Cracker: Password hashes are a common target for attackers, and they can be used to increase or upgrade an attacker’s access to a target device or network. A penetration tester may use a password cracker to detect whether a company’s workers are using insecure passwords that could be exploited.

Most Popular Pen Testing Tools of 2021 

There are various tools available for each of these main types of penetration testing tools. The following are some of the best alternatives for each one


The only commercial tool on this checklist is Nessus. Tenable presents it under a variety of various licensing styles. The number of IPs that can be examined in the free edition is restricted while paying licenses to provide for unrestricted scans and the deployment of several scanners. Because of its extensive library of vulnerability signatures, Nessus is the most popular vulnerability scanner.

A Nessus scan will look over the target system, determine any operating utilities, and include a list of vulnerabilities detected, alongside updated data for manipulation and restoration. These scans incorporate a list of possible attack vectors for getting access to a target network or device to a penetration tester.

Burp Suite

Portswigger’s Burp Suite is a list of device security research techniques. Burp Proxy, their web proxy, is possibly the most well-known of these applications. A penetration tester may use Burp Proxy to carry out a man-in-the-middle attack by sitting between a web server and a browser.

This enables them to analyze and alter network traffic in real-time, allowing them to identify and manage web server bugs or data leakages.


The Network Mapper (Nmap) is software that helps you to examine a network or system. Nmap comes with a wealth of built-in information in the form of a broad range of scan modes. These various kinds of scans are designed to circumvent protections or detect peculiar characteristics that can be utilized to distinguish certain operating systems or applications.

Nmap makes a good balance between accessibility and extensibility. The Zenmap GUI offers a point-and-click interface for carrying out quick scans for new users. Both Nmap and Zenmap, on the other hand, enable more experienced users to use a list of flags to fine-tune the specifics of their network search.


Wireshark is by far the quickest network sniffing platform online. Wireshark has a wide number of integrated protocol dissectors, enabling it to define and break down a variety of network traffic in a consistent fashion. To aid in identifying packets of interest, the Wireshark GUI marks every area of a network packet and includes built-in traffic coloring, filtering, and link following.

Wireshark is something more than a pretty packet dissector below the hood. It comes with a lot of built-in network traffic analysis highlights which can be expanded to analyze custom traffic. This makes it ideal for penetration testing, as it encourages testers to eliminate main elements from a network traffic capture quickly and efficiently.

John the Ripper 

The password breaking tool John the Ripper is well-known and usually used. It is mainly designed for use on CPUs, but GPUs are recommended for faster cracking.

John the Ripper has a broad library of compatible hash formats and supports various of the most popular cracking approaches. It’s also an extremely versatile and customizable tool, enabling users to generate custom candidate password formats for dictionary attacks by defining specific combinations of hash functions.


Eventually, you have to be a good penetration tester with all the needed skills to use and benefit from these tools. You have to understand the pentest process to find and fix any vulnerabilities that appear in any system/app. If your business has a mobile app and/or a website, then it is highly suggested to hire a reliable penetration security testing services company. It will fix any malicious elements of your digital business and decrease hacker threats.
