Cloud Email Security

By investing, wisely, to add cloud email security to your information technology infrastructure, and to minimize spam traffic on your network, you will be saving yourself from the investment in additional hardware, securing a solution with easy management and configuration for a cost as low as $10.00 per employee annually.

It is important to remember that not all cloud email security solutions are the same. Some have spam detection fees averaging approximately 97% which means that 3% of all spam landing on your service is not being identified. With spammers becoming more and more advanced in the way they conduct phishing and malware attacks the chance of the one of that 3% tricking a member of staff is much higher.

Spam detection rates differ based on the steps that are put in place by your chosen cloud based email security solution and how it filters the incoming mail traffic. Many cloud email protection solutions utilize SUBRL and URIBL filters that check the IP addresses of inbound email messages against blacklists of known energy sources of spam and also use receiver verification protocols and Sender Policy Frameworks to be able to reject emails addressed to non existent mailboxes and spoofed email messages.

Generally, cloud email protection solutions also have some kind of “machine learning” mechanism to apply spam ratings to emails based on their composition and content. This process can use tasks called one of “Bayesian Analysis”, “Neural Networks” or maybe Adaptive Spam Filtering”.

Administrators are able to adjust acceptable spam thresholds depending on how effectively these tactics are identifying the incoming spam emails so as to keep the blocking of authentic emails to a minimum level.

The greatest spam detection rates are attained by cloud based email security which includes a greylisting process. When enabled, this particular process stops emails from unfamiliar sources of spam passing through its security screens by rejecting every email and asking for them to be resent. Spammers’ mail servers, as they are already overloaded, do not normally see the resend requests and the spam mail will never be sent a second time. This particular feature is able to generate the spam detection rate over 99.9 %.

Most security conscious companies implement two-way cloud based email protection – scanning their outbound and inbound messages. The intent behind outbound scanning is to recognize email accounts which might have been taken over by cybercriminals and to stop outbound emails distributing malware in phishing attacks on your business associates using company email compromise attacks. These kinds of emails may significantly harm the reputation of a company and may also lead to a business´s IP addresses getting blacklisted – not just adversely affecting communications, but additionally any sites linked to the blacklisted domain.

Compromised email accounts are of specific value to cybercriminals. Reliable accounts (i.e. business accounts with a great email history) are usually utilized to distribute malware infected spam messages to the business’s associates better than attempting to infiltrate each contact separately viaa blacklisted IP address. For the company that the spam emails are mailed from, the damage of credibility with the contacts could be as harmful as if it’d suffered a malware or maybe ransomware attack.
