Your Email Protection Service
As you assess the security infrastructure of your company and your email protection service it may become apparent that you need to do more to try and prevent cyberattacks that are aiming to steal your data or lock you network, requesting a ransom to be paid in order to give you access again.
When you are faced with a situation like this it is time to do some serious research to identify the gaps in your security that need to be addressed. The first step in this is calculating how much, on average, spam email traffic is currently bypassing you security measures already in place. Most email security measures that come with the product with purchases will detect up to 97% of the spam that lands on your email servers.
Using this figure you could estimate that, if you have a staff of 20 people that are sent around 20 emails per day, a total of 400 emails, this means that there are 12 emails that make it past all of your cybersecurity measures every working day. Over an average working year of 260 days this gets even more scary as the figure is then in excess of 3,000. With this level of spam landing on your system you are heavily reliant on your staff spotting and removing spam emails that are basically being created to do everything possible to trick them into replying or downloading a file.
The upshot of this is that you must conduct ongoing cybersecurity training with your staff. While this is an advisable step regardless of how much spam you emails filters are detecting the best result from it is that they will be in a position to spend some of their valuable time addressing the spam attacks themselves. Along with this even the most tech savvy employee can make a random mistake and click on a spoofed email that appears to be from a genuine sender.
If you wish to stop incidents like this taking place then you simply must implement cybersecurity measures that will optimize the email spam detection rate and alleviate the pressure that you staff are facing to spot incoming spam messages. This is where your email protection service must give you complete and utter confidence that your systems are as safe as can possibly be expected.
You can achieve a spam detection rate of just below 100% if you invest in the best features possible. These include:
- SURBL & Real Time Blacklists: Putting these filters in place will fight the arrival of email spam from known sources of cyberattacks. They will check the IP address or domain that the mail message originated from. They will also check to see if they are attempting delivery to inactive email addresses. Additionally the network administrator manager can refine the sensitivity levels of these filters.
- Greylisting: This is a process where every received email message is sent back to the returned to the sender with a request for it to be sent again. Spam email servers will rarely notice this request as they are typically so overloaded it is difficult to spot anything that is unexpected. Should it happen that they are noticed and make it to the server they will be subjected to RBL and SURBL.
