Endpoint security is significant in corporate networks as it protects devices like laptops and smartphones from threats, ensuring that sensitive data is secure. By deploying security measures such as anti-virus software and firewalls, organizations can prevent data breaches, malware attacks, and unauthorized access. This is crucial in maintaining compliance with regulations and protecting the overall integrity of the network. As remote work and mobile device usage increase, effective endpoint security becomes even more essential for safeguarding company assets and ensuring business continuity.
