How does Sophos XG Firewall ensure secure remote access for employees?

Sophos XG Firewall ensures secure remote access for employees primarily by implementing SSL VPN or IPsec VPN for encrypted connections. These technologies provide a secure method for employees to connect to the organization's network over the internet.

SSL VPN, in particular, facilitates secure, remote access without needing additional client software since it can operate through standard web browsers. This makes it user-friendly while maintaining a high level of security through encryption, which protects the data being transmitted from eavesdropping or interception.

IPsec VPN is another robust option that secures the communication between remote devices and the internal network by establishing a secure tunnel for the data. This allows for the confidentiality, integrity, and authenticity of the data being sent, making it an essential tool for remote work scenarios where sensitive information may be involved.

Both VPNs leverage encryption protocols to ensure that the data being exchanged between remote workers and the enterprise network remains secure, which is crucial in protecting against cyber threats.

Other options presented do not provide the same level of security for remote access. An open proxy server could expose the network to various security vulnerabilities, simply allowing traffic without adequate protection. Limiting access to certain IP addresses may restrict access but does not encrypt any data, thus leaving it vulnerable to interception. Requiring
