Avast Business CloudCare Email Security Services (ESS) is a cloud-based system available only to CloudCare Partners. It is a hosted solution which requires the customer to have control of their DNS records, so mail is sent directly to us, and then passed along to the customer's mail server/cloud service. ESS checks email for spam, viruses, and unwanted mail using a variety of custom filters, so that mail is clean before it arrives on the customer's email server, and also offers email archives and encryption.

Email Security Services Components


  • Blocks unwanted email in the cloud before it hits the customer's network
  • Also blocks outbound email that contains spam or viruses, keeping your customers from inadvertently spanning their contacts
  • Provides ten levels of protection and stays up-to-date automatically
  • Spools inbound emails for ten days, which means that a customer's local server outage doesn't have to mean a major disruption

Email Archive

  • Provides email continuity to your customers by giving them on-demand access to email from any location, even if their internal server is down
  • Offers protected and encrypted long-term storage while filtering for spam and viruses in the process
  • Gives your customers the tools to search any email or attachment within the archive on multiple levels

Email Archive Lite

  • Provides customers with convenient, short-term storage
  • Users can access, search, and recover without the need to contact you
  • Improves network performance with secure archiving a rolling, 60-day basis
  • After 60 days, emails and information are automatically deleted

Encrypted Email

  • Encrypted email is maintained in SysTrust-certified and SAS-70 type II Data Centers
  • Deploys easily without additional hardware, software, or training-and saves time with automatic updates
  • Encrypt based on policy and regulatory compliance, along encryption based on subject line keywords, recipients, domains, and more
  • Covers PC-to-PC encryption and mobile devices as well
  • Emails that are sent unencrypted can be automatically encrypted, rerouted, or blocked if they do not comply with policy
