Cloud Based Email Filtering

Cloud based email filtering is one of the simplest and most convenient ways of eliminating unwanted and unsafe emails. Like most cloud based applications, an email filtering solution hosted in the cloud has no capital expense, is automatically updated and offers a high degree of flexibility.

Secure, scalable, and universally compatible, cloud based email filtering is an effective way to mitigate the cost and risks of unfiltered email with minimal maintenance overhead. Furthermore, with a cloud based solution, organizations can manage their online security from any Internet-connected device.

The Cost and Risks of Unfiltered Email

The cost of unfiltered email is typically measured in lost productivity. Researchers have established that it takes an average employee four seconds to identify and delete a spam email. From that information it has been calculated that an organization with 500 employees – each receiving five spam emails per eight-hour day – will lose more than 109 days a year from the lost productivity.

The risks of unfiltered email are potentially much worse. Successful phishing campaigns, spoofed emails and email-based cyberattacks can cost organizations millions of dollars. Without effective protection against these risks, it is only a matter of time before a phishing email succeeds or an attachment containing malware is opened and the network is infected.

The 2020 Cost of a Data Breach report from IBM Security/Ponemon Institute revealed the average cost of a data breach, from a malware infection for example, was $3.86 million. Even data breaches and malware infections at small businesses can cost hundreds of thousands of dollars in losses. By comparison, the cost of implementing cloud based email filtering is typically $10.00 per employee per year.

How Cloud Based Email Filtering Works

Cloud based email filtering works in exactly the same way as other professional email filtering solutions. Multi-layered security mechanisms inspect every inbound email against lists of spammers and other malicious IP addresses. The security mechanisms also check for emails that contravene sender policy frameworks to detect phishing and spoofed emails. Antivirus protections are in place to identify malware, ransomware, and malicious code and advanced spam filters also include sandboxing to identify unknown malware threats.

Any emails that are rejected by the email filter are quarantined – along with any identified by anti-virus software as containing infected attachments or links to websites known to harbor malware. The filters also check outbound emails for spam and viruses to prevent the organizationĀ“s IP addresses from being blacklisted by global blacklisting services and reputation damage. Some spam filters, such as SpamTitan, allow certain data types to be tagged – e.g. Social Security numbers – to prevent the data from being sent via email.

The primary difference between cloud based email filtering and a virtual or physical appliance is the filtering mechanisms operate in the cloud. In order to access the service, organizations simply have to make a small change to their mail exchanger (MX) record in order to redirect inbound and outbound emails through the service providerĀ“s server.

Evaluating the Best Cloud Based Email Filtering Solutions

Not all cloud based email filtering solutions are the same. They can vary in their ability to identify spam block web-borne threats, or recognize bona fide senders. Some filtering solutions will tag spam email but not quarantine it, whereas others give end users the option of how it should be managed.

When evaluating the best cloud based filtering solution for their specific circumstances, organizations should consider the following:

  • Can the advertised levels of spam detection be verified?
  • What percentage of genuine emails get blocked (false positives)?
  • What anti-virus software is used to identify web-borne threats?
  • What method of recipient verification does the solution use?
  • What cloud based hosting options exist for the solution?
  • Can independent testimonials be provided by the service provider?

Thereafter, which is the best cloud based email filtering solution may depend on factors such as ease of use, technical support, and cost. Wherever possible, organizations should request a trial run of the solution in order to see it action in their own environment – and to see what results it returns.
