Which of the following Sophos products focuses on endpoint protection?

The correct choice is centered on the specific function of the software in question. Endpoint Protection is a dedicated solution designed to safeguard individual devices within a network, such as laptops, desktops, and mobile devices. It addresses various types of threats including malware, ransomware, and phishing attacks, ensuring the security and integrity of endpoints against these risks.

In contrast, the other options serve different purposes within the realm of cybersecurity. Firewalls are primarily used to monitor and control incoming and outgoing network traffic based on predetermined security rules, effectively acting as a barrier between trusted internal networks and untrusted external networks. Managed Detection and Response (MDR) offers advanced threat detection and response capabilities, typically involving human expertise combined with technology to address complex threats, but it does not specifically focus on individual endpoint protection. Lastly, a VPN (Virtual Private Network) provides secure and encrypted connections over the internet, protecting data in transit but does not directly protect endpoint devices themselves from threats.

Thus, Endpoint Protection stands out as the solution specifically tailored for securing individual endpoints, making it the accurate choice in the context of this question.
