Each year, an increasing number of spam emails are sent to corporate employees, threatening to clog corporate email servers and slow productivity to a crawl. With the rising concern to business that spam has created, more organizations are turning to cloud-based spam filtering solutions to ameliorate the threat of disruption from spam.

Beyond being a mere constant irritation that fills up mailboxes and distracts users from completing their daily tasks, spam can also be a security threat. Many spam emails contain malware, ransomware, or viruses, or are phishing attacks which will, if allowed to propagate on your network, bring business to a standstill and possibly be devastating to the corporate bottom line.

In a cloud-based spam filtering solution, spam is stopped before it reaches the corporate network. This keeps spam messages out of employee inboxes, which in turn denies possible malicious content the opportunity to spread across your network.

A cloud-based anti-spam solution also has the benefit of being free of hardware costs and maintenance overhead, as well the costs of software.

Such a cloud-based solution is an easily implemented and affordable way to ensure that your network remains free of spam and any email-borne threats it might contain.
