Quick Answer

Cloud-based email security puts the filtering layer in front of the corporate network, so spam, malware, phishing, and zero-day attachments are caught at the gateway rather than after they hit user inboxes. With 91% of security threats originating in email, the gateway position matters: stopping a payload before it reaches an endpoint means it can't propagate laterally. DuoCircle's cloud solution provides spam filtering with continually updated threat intelligence, virus and malware blocking, real-time scanning of suspected URLs and attachments at click time, and a single admin console for policy across the organization. Because it's cloud-hosted, there is no on-prem hardware, software, or provisioning to maintain, and threat intelligence updates apply tenant-wide automatically. The two practical effects: fewer threats reaching endpoints (system performance and security both improve), and one policy surface to manage instead of per-server or per-mailbox configuration.

Cloud-Based Email Security

The security of any organization’s information to a large degree is only as good as the security of their email. With 91% of security threats originating from email-based vulnerabilities, organizations must prioritize systems that protect against email attacks.

With DuoCircle’s Cloud-Based Email Security solution, your organization will be protected against a wide variety of threats. With any email security solution, you can expect spam protection as well as virus and malware mitigation, but DuoCircle also provides secure cloud spam protection, allowing your organization to quickly respond to threats that could spread throughout the entire enterprise. This additional layer of protection goes far beyond what traditional email security measures are designed to provide.
