In today's digital age, people are utilizing technology in all aspects of life. In work, study, socializing, entertainment, in addition to online banking and shopping, technology has become an integral part of our life. The rapid advancement of the internet and communication technologies means most people utilize at least one computing device. For example, according to Statista, the number of smartphone users worldwide surpasses three billion and is forecasted to increase by several hundred million in the coming few years.
Whenever a user connects to the internet, he/she is connected to a network with billions of other users. In such a broad public environment, we cannot trust anyone. Unfortunately, similar to the real world, the internet is full of criminals from all types and places aiming to harm IT systems or steal sensitive information for commercial gain.
Cyber attacks are becoming more sophisticated and are increasing rapidly. According to Risk Based Security, the total number of records compromised in 2020 exceeded 37 billion. On the other hand, Cyber Security Ventures projected the global cost of cybercrime annually would reach $10.05 trillion by 2025.
It is essential to install security software to keep your operating system and sensitive files away from hackers and other cybercriminals. This article will discuss the top free security solutions that any user or organization can leverage to protect endpoint devices and home/office networks. It is good to mention why organizations must use advanced security solutions to protect their sensitive data and IT systems from malicious actors.
Why should businesses use security programs?
Protect against ransomware attacks
Ransomware is among the most significant threats that organizations face today. Unfortunately, ransomware does not announce its presence until it finishes encrypting infected system files.
Before using a security solution, it is essential to check its capabilities and make sure it can detect and prevent ransomware. Most of these solutions are commercial.
Protect sensitive business data
Enterprises computing devices such as servers, endpoints, and mobile devices contain a trove of sensitive data. Without robust security programs such as antivirus, firewalls, and IDS, hackers can compromise this data and sell it to competitors or leverage it for their financial gain.
Increase customer's trust and boost sales
Cybercriminals utilize viruses and other malware types to steal data or disrupt normal business operations; however, the real damage is done to business brand and reputation. The majority of customers will lose trust in a business after a data breach. A report published by Centrify found that 65 percent of data breach victims lost confidence in an organization due to the breach.
On the other hand, customers are more willing to deal with a company that protects their data. They will feel comfortable purchasing products and services from highly secured enterprises.
