Emails are the most common medium for attacking an organization. Hosted email security solutions contain advanced features in order to increase spam detection rates and limit the number of unwanted and malicious emails entering your network.
Why is blocking spam and unwanted mail so important?
At best spam is an annoying nuisance that heavily impacts an organization’s productivity levels, dealing with endless unwanted emails entering the system.
However phishing attacks – activated when a user clicks on an infected attachment or URL contained in an email – can give attackers access to sensitive company data and access to a whole network. Being subject to such threats can place an organization’s entire future in jeopardy.
In order to protect against spam and phishing attacks, organizations can create an account with a hosted email security provider, by adding their domain and a domain administrator, and connecting to the service provider´s servers by redirecting their MX records. As a result all incoming mail will pass through the email security provider’s servers and they are filtered according to the policies created by the domain administrator.
Scheduled reports will be sent to each user when mail is quarantined by the hosted email security software. Domain administrators can easily monitor the volumes of spam emails being detected, quarantined and rejected in real time via a portal, or historically via customizable reports.
Most hosted email security solutions use Real Time Blacklists to block emails from known sources of spam.
However those with higher spam detection rates use greylisting to also identify and inspect emails from previously unknown spam sources or from new threats. If the mail is legitimate, the sending server will be instructed to re-send and the mail will be accepted.
While greylisting can delay the delivery of emails to users, the benefits are substantial.
Hosted email security software with greylisting detect 99% of spam email, as opposed to 96.86% for those without greylisting. This can result in thousands of dollars being saved in lost productivity, as well as significantly reducing the potential for malicious emails to enter an organization’s network– and usually for no additional cost.
As a result Greylisting is an essential component of any hosted email security solution
