DuoCircle's Spam Filtering Gateway sits in front of cloud-hosted or on-prem mail servers and provides: 99% spam removal with a 0.0001% false positive rate, 100% protection against viruses and malware with 100% uptime, user-configurable content filtering, per-employee allow and block lists, and support for SPF, DKIM, and DMARC validation. The Advanced Threat Defense bundle adds zero-day protection, attachment blocking, real-time activity logs and click reporting, Smart Adaptive Quarantine that pushes spam-sorting back to the sender, a 30-day MX backup queue for outage protection, unlimited users, and 24/7 chat, email, and phone support. Cloud delivery means no hardware costs, no on-prem maintenance, and continually updated threat intelligence.

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.
