    WHAT CUSTOMERS SAY:

    Relief with Mimecast

    Unified platform

    Cisco’s email security comes as multiple, separately configured products that aren’t fully integrated. The gateway handles inbound mail while a different API tool covers internal threats. Managing both is exhausting.

    Mimecast secures inbound, outbound, and internal email through one platform. One console, one policy engine, one place to investigate threats.

    Maintenance & updates

    Talos is impressive, but the intelligence stays siloed in Cisco's network products. Correlating email threats with non-Cisco stack takes manual work.

    Additional ingestion and sharing of data and IOCs with more than 350 security tools is possible via purpose built API integrations that are quick to set up.

    Email archiving

    Cisco has no native archiving solution. We had to buy a separate product and manage another vendor just to meet compliance requirements.

    Mimecast includes cloud archiving out of the box. Tamper-proof storage, instant search, and compliance reporting without a third-party tool.

    Email continuity

    When Microsoft 365 goes down, Cisco offers no fallback. They queue emails for 72h when the primary mail server goes down. Users sit idle waiting for their email to come back online.

    Mimecast keeps email flowing during outages. Employees access a continuity portal and keep working while we wait for Microsoft to recover.

    Add-on sprawl

    Full protection requires stacking Cisco products. Gateway, threat defense, and DLP are all separate line items with separate configs.

    Mimecast bundles security, archiving, continuity, and training in one license and platform. We know exactly what we pay and what we get.

    Vendor lock-in

    Cisco email security works best when you run Cisco everything. Customers struggle with integration beyond Cisco functionality.

    Mimecast is vendor-agnostic. It plugs into Microsoft 365, Google Workspace, CrowdStrike, Splunk, and over 350 other security platforms.

    Frequently Asked Questions

    Mimecast delivers unified email security, archiving, and continuity in one cloud-native platform. Cisco IronPort splits protection across separate gateway and API products, requiring more configuration, maintenance, and add-on purchases to achieve comparable coverage. Buying either their SEG or gatewayless tool (but not both) can also lead to coverage gaps you wouldn’t face with Mimecast - even when you choose our step-in bundle.

    Mimecast delivers over 40 intercommunicating layers of AI-powered detection to protect your organization. We combine advanced, behavioral AI with time-of-click URL scanning, rewriting and deeply scanning every link, and full emulation sandboxing for all attachments. Our platform goes beyond traditional perimeter filtering by analyzing relationship patterns across mailboxes, organizations, and our global user base, and by assessing message intent and linguistic context using NLP. Integrated human risk management further strengthens defenses by identifying users most vulnerable to social engineering tactics—the very threats that legacy solutions like Cisco IronPort, which lacks native user behavior analysis, often miss.

    Yes. Mimecast's built-in continuity portal lets employees send and receive email during Microsoft 365 outages. Cisco offers no native continuity solution, leaving users without email access until Microsoft recovers.

    No. Mimecast deploys updates automatically across its cloud-native platform with zero maintenance windows. Cisco's architecture requires scheduled upgrades and hands-on patching, leading to planned downtime.
