Adding Hosted Email Security to Your Network

Adding Hosted Email Security to Your Network is a smart step and one completed by any organization that has the best interests of its clients, associates and staff in mind.

This solution is designed to mitigate the threats posed by cybercriminals by ensuring the highest possible spam detection rates are in place to minimize the amount of phishing, malware and ransomware traffic entering the network.

Hosted cloud filtering solutions require minimal maintenance, with software updates being performed by the company providing the service. They also have the advantages of being universally compatible with every operating system, infinitely scalable and cost-effective – requiring no hardware investment or additional, and with 100% support available from the vendor’s technical department.

How Hosted Email Security Works:

  1. Business agrees to purchase solution, account is registered
  2. System administrators include their domain to the vendor and designate a domain administrator
  3. System managers point MX records to the vendor’s servers.
  4. User policies are set up using current directory tools
  5. Received email traffic is reviewed with the cloud filter thanks to the parameter set up by the system administrator.
  6. System administrator monitors reports on spam received and alters the spam thresholds to address this.

This is a simple, intuitive procedure for System administrators to competently the safety of business email servers and maintain the integrity of all data and private information. There is also the capability for specific domains and IP addresses to be whitelisted and allow them to avoid the filtering process, leading to a delay in business critical emails being delivered.

What is the Greylisting Process?

The best email filters deploy Real Time Blacklists and SURBL filters to prevent inbound emails from recognized sources of cyberattacks as described above. Here is an opportunity of making these security levels even stronger by implementing a solution called greylisting. This is a process that is carried out in the following steps:

  1. Company mails servers receive inbound traffic
  2. Alli inbound traffic is returned to the server that sent it with a request for it to be resent. Overloaded spam email servers are quite unlikely to recognize requests for the email to be sent a second time. This is the way that the process roots out unknown sources of spam.
  3. When emails are sent a second time following this request they go through SUBURL and Real Time Blacklists in order to be certain that any email do not include anything malicious.

By utilizing these greylisting steps hosted cloud filters can produce a spam detection rate in excess of 99%.
