What is the key difference between Sophos Firewall and the SG Series?

The key difference highlighted in the context of the Sophos Firewall and the SG Series is that the XG Series includes advanced features and performance optimizations compared to the SG Series. The XG Series has been designed with modern threats in mind, incorporating cutting-edge technology and improved user interfaces that support advanced security capabilities such as deep packet inspection, enhanced reporting, and security automation, which are required for contemporary network environments.

The SG Series, while effective and reliable, lacks some of the newer features and performance improvements that the XG Series brings to the table. This includes enhancements in threat intelligence, user experience, and system responsiveness, all geared toward providing a more comprehensive defense against evolving cybersecurity threats.

Focusing on the other options, it is essential to note that the SG Series is not cloud-based; rather, it is primarily an on-premises solution. Additionally, while some aspects of customization may exist within both series, the XG Series is specifically designed to offer a wider range of customizable features based on the advanced capabilities it provides. Lastly, saying there is no difference implies the two series are interchangeable, which overlooks the significant technological advancements that differentiate the XG Series from the SG Series.
