2.8 Updates
New threats are constantly evolving on the internet: viruses, spyware, and other security attacks.
To ensure that your appliance is able to deal with these changes, it automatically downloads and
installs updated information from SophosLabs.Website URL categorization data is also updated:
every 5 to 30 minutes for the standard categorization data and every hour for the enhanced
categorization data.
SophosLabs is a global network of highly skilled analysts with more than 20 years’ experience in
protecting businesses from known and emerging threats. SophosLabs sites around the world
provide rapid response to evolving threats like viruses, spam, phishing, spyware, and other
malware, 24 hours a day, seven days a week.
The appliance constantly updates anti-virus definitions and Sophos website categorization data
throughout the day. It also downloads "Critical" and "Maintenance" software updates. Critical
updates are security-related and protect against anything that can compromise the appliance.
Maintenance updates contain the latest non-critical software updates and bug-fixes. Maintenance
updates can be installed on a configurable schedule to avoid slowdowns at peak periods.
