Which of the following features is common in Sophos firewalls?

The feature that stands out as common in Sophos firewalls is the simultaneous support for both IPv4 and IPv6 protocols. This capability is essential as organizations continue to transition to IPv6 due to the exhaustion of IPv4 addresses. Supporting both protocols concurrently allows for greater flexibility in network design and ensures compatibility with a wider range of devices and internet services. Sophos firewalls are designed to accommodate diverse networking needs, making them effective in environments that require robust and versatile connectivity solutions.

In contrast, focusing solely on user permission management would limit the capabilities of the firewall. Filtering URLs, while important, is just one aspect of web protection and does not encompass the broader security features offered by Sophos firewalls. Similarly, minimal reporting capabilities would undermine the utility of a firewall in providing deep insights and analytics critical for network security management. Therefore, the choice that reflects an essential and versatile feature of Sophos firewalls is the support for both IPv4 and IPv6.
