An email protection service provides a contact filtering and virus scanning program which will help defend networks against both internal and external danger posed by cyber threats.
Usually, a contact safety service features a top spam detection fee (above 99.9 %), identifies efforts to compromise business mail accounts, and also stops emails being sent from business mail accounts which could end up in the business’s IP address getting blacklisted.
This is also an invaluable tool for identifying viruses which might have been inadvertently placed on the network by a member of staff. This may occur if, for instance, a worker adds an infected USB flash drive to the network on the desktop workstation or laptop. If this happens, and the staff member’s email account becomes compromised, then outbound email scanning can spot this and prevent anything untoward from being sent to a valued business contact.
An email filter will achieve a top spam detection rate by way of implementing a process referred to as greylisting. When enabled, this method returns all incoming messages to the originating mail server, asking for it to be resent. Normally the genuine mail servers respond to the email within a few minutes whereas Spammers’ mail servers are usually too occupied mailing out spam to react to the request, and so fail to resend the spam email.
Following the reply being sent from a, supposedly, genuine, mail server the email content filter then runs it from a number of further checks to make sure that the email is legitimate. These checks include Real Time Blacklists as well as SURIBL directories to find matches with IP addresses of acknowledged spammers, receiver verification checks to make certain each email is actually being sent to a currently active email account and HELO testing to prevent spoofed emails making it past your security measures.
Using this process, an email content filter will spot emails from both known and unknown sources of spam. With this in place your system manager can also refine the acceptable spam thresholds after they review the automatically produced reports. Using these methods it has been shown that companies are able to reduce inbound email spam traffic by an average of 67%. This is a huge advantage to have in the fight against phishing, ransomware and malware.
Among the advantages of a good spam detection rate is the fact that fewer phishing emails will avoid detection. A successful phishing attack could lead to a worker revealing the login credentials for their email account or allow a spammer to take over the bank account with potentially severe consequences. With management of the email account, a spammer is able to release Business Email Compromise (BEC) strikes or even make use of the account to transmit malware laden spam email to the business’s associates from your domain which would be listed as a “trusted account”.
A spammer will look to take over a trusted account in order to bypass the email filters that your business clients have in place. They will not be seen as a threat when sending computer viruses from your domain and IP address. Something like this happening would severely damage your business relationship.
