However for even greater business email protection you can also add in the Kaspersky, Cyren and/or Sophos antivirus engines for the ultimate protection. This enables you to take advantage of the strengths of each engine. Antivirus engine vendors have different response times to new viruses and malware. This capability ensures your system can always detect new threats in the shortest possible time.
