Secure Managed Email Services (SMES) offers an additional layer of protection for agency networks, proactively scanning and monitoring email traffic before it enters the system. The service supports email security functions such as anti-virus scanning, anti-spam filtering and content control. Security engines are continuously updated to maintain effectiveness against emerging threats and inappropriate material. SMES can scan millions of email messages a day without noticeable delays to end-users. The service works in conjunction with existing agency email systems and can be implemented without additional investment in hardware and software at agency sites.
