Created to safeguard networks from internal and external attacks, an email protection service is an email filtering and virus scanning solution.
In the majority of cases a solution like this will boast an excellent high spam identification rate (above 99.9%), recognize attacks aimed at infiltrating company email accounts, and stop the sharing of any emails from company accounts that could lead to the organization IP address being added to a global spam blacklist.
This is a vital weapon to have in the war against cyber criminals as it can spot a computer virus that a member of your workforce may have unknowingly placed on your network. Occurrences like this can take place when someone introduces an external storage device that was used on a different network or if an infected mobile device links up with the business WiFi. For this reason outbound scanning is an extremely important feature to have in your cybersecurity solution.
Email Protection & Excellent Spam Detection
It is possible to record an excellent high spam detection rate with an email protection service if it includes the feature known as greylisting. Greylisting works by sending back all inbound emails to the mail server they came from while asking for the message to be sent once more. In most cases the email is sent again promptly. However, the emails server that a hacker uses are normally too busy sharing huge amounts of spam email to notice the request and the request is never processed.
This means that, after an email has been sent back to you a second time, it can be subjected to further tests to verify that it is authentic. These test include Real Time Blacklists and SURBL databases to identify any originating IP addresses that are connected to previous spamming campaigns and recipient verification checks to review if the mails are only being sent to active group email accounts and, finally, HELO tests to stop spoofed emails bypassing your security measures.
Using these methods an email protection service eliminates emails from known and unknown sources of spam mail. Greylisting has seen great success with some organizations recording a drop in the amount of spam landing in inboxes of up to 67%.
Email Protection Preventing Account Infiltration
If you are infiltrated by a phishing attack login details can be obtained by cybercriminals leading to serious ramifications including further fraud, bank account hacking and even fines being sanctioned against you by regulatory authorities. If you focus on introducing a high spam detection rate on your network then you will avoid this scenario. Otherwise a hacker may be able to initiate Business Email Compromise (BEC) attacks or leverage an email account on your network to share spam emails to your saved business contacts. This is an ideal case for a cybercriminal as it is likely that your domain will have been whitelisted by your business contacts to any possible delay in important messages being delivered to them.
If this were to happen it would seriously impact the good reputation that you have spent so long building for your company. Additionally, your IP address or domain could end up on a global blacklist if the email protection service of a recipient’s cybersecurity solution marks it as a known sender of spam emails.
Having an outbound email protection service in place will stop this from happening and put your business in a safe and trusted position.
