Anti-Spam and Anti-Virus Protection for Emails

Anti-spam and Anti-Virus Email hosting

Ever get unwanted email?  Asking that question is like asking if you’ve ever tasted something you didn’t like.  We all have. But you can reduce your unwanted spam emails with a good anti-spam product.

Many anti-spam vendors are offering low cost software and businesses can now afford advanced email spam and virus protection with a simple to use interface. Our Web Hosting product comes with excellent anti-spam included, but you may want a desktop version of the software for more control.  The great thing about technology is that is always evolves, gets faster,  has additional features and becomes more economical. Over the past decade the same evolution has taken place with anti-spam technology and services. Increased spam and email users means an increase demand on quality products, which means increased supply.

Typically its not practical to have anti-spam software running on desktops in a networked business environment.  Its much easier and cheaper to block the spam at the source… your email server. Managing all employee junk email software at the desktop is not realistic. It can be a nightmare and costly in terms time, updates, and licensing.

Anti-spam appliances are hardware/software devices that sit in front of your email server so that when email comes in it will first go to the spam appliance and the email will be scanned for spam as well as viruses. Their filter will block the message if it identified as known spam or if it contains malicious attachments, like spyware or viruses. Some appliances can even quarantine messages, that is if the filter is not clear if the email is legit or not it will quarantine and hold the email and it will be stored until the recipient deletes it, releases it to their email box, or they can white list a trusted correspondent so that future emails will not be held back. This will greatly reduce the load on your email server and reduce your bandwidth needs.

I was once an email server administrator for a few years at an ISP.  At that time, we documented that over 90% of all of our email traffic was spam.

Most ransomware attacks and virus outbreaks occur via email and for little cost an appliance can block viruses before they reach your network and user’s inboxes. This provides an extra layer of defense in addition to your current anti virus solution.

If your website is hosted with Secure Digital Technology, your email is already protected against spam and viruses. If you’re interested in consulting to help you configure desktop or server systems for your business, we can help with that to, just contact us.

If you decide purchase your own anti-spam filter, a subscription to updates may also be required. Be sure you get upfront pricing for the add-ons that you will need.  For example, if you’re running Office 365 or Microsoft Exchange, you may need a special add-on or plugin. If you have more than 100 email users and the technical staff to maintain the spam appliance, buying your own filter may be your best option as you’ll have more control over it.

Generally the basic model, allowing your hosting company to support it, will work for most organizations. Large organizations with thousands or tens of thousands of users will require a spam filter appliance with increases capacity and features. Spam appliances are designed to work with all mail systems but some do have specific enhancements for Exchange server, Microsoft’s popular collaboration software and mail servers that support Active Directory or LDAP (light weight directory access protocol). Spam appliances use the LDAP protocol to verify recipients before delivering messages to your email server, this avoids consuming additional server resources.

If your business has five to fifty employees, then an outsourced anti spam and virus filter service is going to be a good economical choice for your organization, and Secure Digital Technology Group can help you find one, even if our hosting isn’t the best fit for you. Fees are typically based on the number of users and you only pay for what you use. You will not have hardware to buy, maintain, or upgrade. The upfront cost is minimal and most email filtering providers will let you try the service for free at first. Another added benefit to outsourcing your spam control is redundancy.

Anti-spam technology is constantly improving and the costs are getting lower. If you have a really skilled set of technical developers and devops group, you could even find open-source solutions that can help you with little to no costs. With increased productivity and an added layer of defense against virus attacks, an anti-spam appliance or service is something your business can not afford to be without.
