What Is Endpoint Security?
Endpoint security is the process of protecting devices like workstations, servers, and other devices (that can accept a security client) from malicious threats and cyberattacks. Endpoint security software enables businesses to protect devices that employees use for work purposes or servers that are either on a network or in the cloud from cyber threats.
The modern business landscape is seeing an increasing volume of cybersecurity threats from increasingly sophisticated cyber criminals. Hackers launch a cyberattack every 39 seconds, with a daily total of 2,244 attacks. Endpoints are one of the most common targets, given the sheer number of them in use to connect to networks. According to Strategy Analytics insight, there were already 22 billion connected devices in 2018, which is predicted to rise to 38.6 billion devices by 2025 and 50 billion devices by 2030. As a result, Verizon’s threat report found that up to 30% of data breaches involved malware being installed on endpoints.
Every endpoint that connects to the corporate network is a vulnerability, providing a potential entry point for cyber criminals. Therefore, every device an employee uses to connect to any business system or resource carries the risk of becoming the chosen route for hacking into an organization. These devices can be exploited by malware that could leak or steal sensitive data from the business.
In the face of this, it is imperative for businesses to deploy solutions that can analyze, detect, then block and contain cyber attacks as they happen. Organizations also need to collaborate with one another and utilize technologies that provide their IT and security teams with visibility into advanced threats, enabling them to quickly detect security risks for swift remediation of potential issues.https://www.youtube.com/embed/umB71Azc4XM?si=lHE9IFBrpgU_kcCu
