Mail Filtering: An Integral Part of an Organisations Security Posture

In a world where there are multiple methods of communication, email is still king. A business can’t function without it.

Billions of emails are sent daily between individuals and companies and research shows that even though most of these emails are warranted, spam emails are more prevalent than ever.

Once upon a time Spam was easy to identify – often promoting products or services that were sent in bulk to a sales prospecting mailing list.

Impact on business would have been minimal and spam was more annoying than anything else.

Unfortunately, the people sending Spam have become more sophisticated and more determined to have their information reach you. Spam has matured into an aggressive threat, delivered by persistent attacks and rapidly evolving techniques.

 

As mentioned in our previous blog, Spam now contains malware, with hackers sending cleverly disguised emails to your inboxes. Once opened, it will infect a device or attempt steal private data. Malware will spread across the entire network and beyond to include your clients and vendors.

Relying on employees to pause and examine every link and attachment is a risky strategy and relies on humans behaving with computer like logic, it will only take one mistake to compromise the network.

 

To counteract this threat, a Mail Filtering system can be deployed.

The solution benefits an organisation in multiple ways by:

(1) Blocking Threats: The spam filter’s purpose is to block the spam from ever reaching your employees’ screens. The threat is automatically identified and either held securely or immediately deleted. This is the best way to avoid activating spam malware, as it’s so easy to click through links in an email that seems authentic and important. The effects of that one spam click may be instantaneous or may lie hidden for months. Removing the email before it becomes a risk is a much better option.

(2) Filtering legitimate emails: Real mail needs to be able to stand out and avoid the trash. Anti-spam filtering has sophisticated recognition abilities which block spam only and allow real mail to land safely in mailboxes.

(3) Meeting data regulations: Many businesses are subject to strict privacy and data storage regulations, some more so than others. To continue operation, they have to meet conditions including always using spam filtering to reduce the risk of data breach.

(4) Increasing Productivity: Employees should not be wasting their time on tasks not directly related to their work. If employees have to sift through a lot of spam in their email inboxes to find the legitimate business related mail they are looking for, that is not their fault. It’s the company’s fault for not providing them with a spam filtering service to automate the process of deleting spam for them.
