Email Spam Filter for Exchange

It is important, in the face of the ever-increasing efforts of hackers to steal private data, that the security of your Microsoft Exchange Email server is addressed as soon as possible.

Neglecting to put in place adequate measures could lead to the private data that you are sharing being stolen and used to commit fraud. If you fail to do so then your organization will run the risk of not having an automated update completed and will leave databases susceptible to new strains of spam and malware.

This solution operates by running a range of checks on incoming emails. Searches are conducted to see if they are originating from any blacklisted sources or IP addresses known to host malware.

The is a granular solution, meaning that internal staff members with responsibility for the security of the network can manage just how strict the parameters established are. Different thresholds can be set for different departments. In addition to this security updates are applied in real time, meaning that you will not be dependent on IT staff manually running updates – leading to a vulnerability. Each inbound email is scanned by anti-virus solutions and SUBRL filters conduct a review to see if URLs that often appear in unsolicited emails and malicious links used for phishing or malware distribution are included.

Outbound scanning is also an important feature to insist on having. If you do not have it then you run the risk of having your group’s IP address is added to a global blacklist. This usually happens when unsuspecting members of staff click on a link in an email that takes them to a malicious website or reply to a phishing message. The anti virus solutions and spam filters that come free with Microsoft Exchange do not include this measure.

Holding anti spam software for Exchange 2013 up against everything else that is available on the market should be with a contrast versus Microsoft´s premium “Advanced Threat Protection” (APT) service. There has been some criticism of this service for involving too much maintenance. There are a number of other key security features missing from this solution.

Despite being more expensive than third party anti spam software for Exchange 2013, APT lacks several key security mechanisms such as greylisting – a strong anti spam measure that works by returning all inbound emails with a request for them to be resent. SPam email servers are generally too busy for these to be noticed.

What Should a Third Party Solution Include?

Ask yourself the following questions to help you identify the features that you require:

  • What is the process for filtering spam emails?
  • Is there a known, and verified, spam capture rate?
  • What is the percentage of authentic emails that is regularly marked as spam?
  • What happens if there are email outages? Will messages that were received during downtime be received after being scanned?
  • Are there current customer reviews available?

If you are investing, as you should, in a third party email filters then there is a lot that you need to think about. Whatever your level of investment it is important that you do everything possible to avoid cyber attacks from infiltrating your databases. These could lead to breaches and resulting regulatory fines or , worse, again, hackers stealing hard-earned money from you and your clients.
