Recent developments in technology and the shift of work from office space to remote working have made cybersecurity something that every business needs to take seriously. Besides, new technologies such as big data, IoT, Artificial Intelligence (AI) and machine learning are gradually moving into our daily lives accompanied by cyber threats. Additionally, the usage of mobile and web apps in transacting financial information has put the complete digital working system exposed to cybersecurity breaches. Successful security attacks result in devastating consequences to the victim including damaged reputation, financial loss, compromised business and customer data. However, reaching a 100% security level is near to impossible. Cybersecurity entails securing networks from unauthorised access and attacks, protecting systems from attacks executed through endpoints, encrypting network communications. Internationally, cybersecurity breaches have caused a yearly loss of US$20.38 million in 2019. Plus, cybercrimes accounted to 0.80% of the total loss of the entire world’s GDP, which summed up to approx US$2.1 trillion that year. A cybersecurity tool stack should include cybersecurity monitoring tools, cybersecurity analysis tools, cybersecurity detection tools, network defence or network monitoring tools, cybersecurity software tools, network security audit tools and attack tools, and computer network defence tools. Henceforth, Analytics Insight brings you a list of cybersecurity tools that are expected to dominate in 2021.



Firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. This has made firewall one of the most crucial cybersecurity tools. Its purpose is to establish a barrier between a system’s internal network and incoming traffic from external sources, such as internet, in order to block malicious traffic like viruses and hackers. If there are any connection attempts, it decides whether to pass it freely or not in a computer or network.


Kali Linux

Kali Linux is one of the most popular OS used by cybersecurity experts all over the world. Kali Linux is a Debian-based Linux distribution aimed at advanced penetration testing and security audition. Kali Linux contains several hundred tools which are geared towards various information security tasks. The main benefit of the tool is that it can be used by users with different levels of cybersecurity knowledge. As such, it doesn’t require an advance cybersecurity specialist to be competent. Most of the tools available in the operating system are executable meaning that users can monitor and manage the security of their network system with a single click.



NMap or Network Mapper is a free open-source tool for vulnerability scanning and network discovery. Network administrations use NMap to identify what devices are running on their systems, discovering available hosts and the services they offer, finding open ports and detecting security risks. NMap can be used to monitor single hosts as well as vast networks that encompass hundreds of thousands of devices and multitudes of subnets.



Metasploit is a popular penetration testing tool. The Metasploit Framework has a suite of extensively used tools that offer a broad platform for pen-testing and exploit developments. IT experts and cybersecurity professional use Metasploit to accomplish varying security objectives. These include identifying vulnerabilities in network or system, formulating strategies for strengthening cybersecurity defence and managing the completed security evaluations.


Antivirus Software

Antivirus Software is designed to find known viruses and oftentimes other malware such as Ransomware, Trojan Horses, worms, spyware, adware, etc. that can have detrimental impacts on the user or device. Antivirus software alerts the system in case of any virus and malware infections.



Wireshark is a network protocol analyser or an application that captures packets from a network connection such as from the computer to home office or the internet. It runs on Linus, Windows, Unix, Solaris, Mac OS, NetBSD, FreeBSD, and several others. Wireshark can be extensively used by educators, security experts, network professionals and developers.


PKI Services

PKI or Public Key Infrastructure is the framework of encryption and cybersecurity that protects communications between the server and the client. PKI is essential in building a trusted and secure business environment by being able to verify and exchange data between various servers and users. Through encryption and decryption, PKI is based on digital certificates that verify the identity of the machines and users that ultimately prove the integrity of the transaction.


Cain and Abel

Cain and Abel is one of the earliest cybersecurity tools used to uncover vulnerabilities in Windows Operating systems. Cain and Abel enable security professionals to discover weaknesses in the password security of systems running on the Windows Operating System. It is a free cybersecurity tool used for password recovery. Its functionalities include the ability to record VoIP communications. Also, Cain and Abel is capable of analyzing routing protocols to determine whether routed data packets can be compromised.


Network Security Monitoring Tools

Network Security Monitoring Tools or cybersecurity monitoring tools can help businesses detect outside network threats. It can also be used to analyze threats originating from inside the network. It can prevent many insider thefts by analyzing historical data to identify unusual or suspicious file share access, then alerts can be set up to warn of specific network activity by both traffic analysis and IDS engine from on-premise or cloud networks.



Netsparker is a commercial security tool that acts as a web app security scanner. Netsparker is a dead accurate, automatic, and simple to use web app security scanner. This tool is mainly used to identify security risks like Cross-Site Scripting (XSS) and SQL injection in web services, web apps and websites automatically.
