Complete defense against viruses, spyware, adware and PUAs across the widest range of platforms of any vendor. Sophos Anti-Virus is 100% Checkmark-certified for spyware detection.
PureMessage for Microsoft Exchange
Integrated gateway and messaging protection from spam, viruses and spyware. It scans all inbound, outbound and internal email messages and Exchange message stores to protect against new or unknown email-borne threats and prevent loss of sensitive and confidential data.
Sophos AutoUpdate
The smallest, fastest protection is automatically distributed at pre-set times or on-demand. Failsafe updating and bandwidth throttling ensures remote laptop users stay protected.
Centralized cleanup
Computers can be completely disinfected in a single operation. Unwanted registry entries, running processes, and even files on disk are removed.
Intrusion prevention
Sophos Client Firewall offers zero-day protection, preventing intrusion by hackers and application hijacking, and blocking malware and spyware from stealing and distributing confidential information.
Proactively protect against known and unknown threats
Behavioral Genotpye® protection identifies malicious code and blocks it before execution, giving the benefits of a Host Intrusion Prevention System (HIPS).
High performance scanning
Scanning can be performed on access, on demand and automatically at scheduled times. Decision Caching™ technology means only those files that have changed are rescanned.
