Basics
At its core, Sophos Firewall acts as a barrier between your internal network and the outside world. It analyzes network traffic and enforces security policies to ensure that only authorized and safe connections are allowed. Sophos Firewall achieves this by examining various aspects of network communication, such as the source and destination IP addresses, ports, and application protocols.
One of the key features of Sophos Firewall is its deep packet inspection capability. This technology enables the firewall to analyze the content of network packets in real-time. By inspecting the data within each packet, Sophos Firewall can identify potential threats, such as malicious code or suspicious behavior, and take appropriate action to mitigate the risks.
Another important aspect of Sophos Firewall is its ability to create and manage virtual private networks (VPNs). VPNs allow authorized users to securely access the internal network from remote locations. With Sophos Firewall, organizations can set up VPN connections to ensure that remote employees can securely access company resources while maintaining the confidentiality and integrity of the data being transmitted.
