Service Level Agreement (SLA)

MetaDefender for Microsoft 365 is committed to delivering a reliable and high-performance email security solution. This Service Level Agreement (SLA) outlines our service availability and content delivery performance commitments to our customers.

Platform Availability

We guarantee 99.9% monthly uptime for the MetaDefender for Microsoft 365 platform. This includes our web interfaces and backend processing systems.

Uptime Calculation Excludes:

  • Scheduled maintenance (with at least 24-hour advance notice)

  • Force majeure events (natural disasters, internet backbone outages, etc.)

  • Downtime caused by third-party services or customer infrastructure

Delivery Performance

We commit to ensuring efficient content processing under normal operating conditions:

  • 90% of content (P90) will be fully processed and delivered within 1 minute from the time they are received by our platform.

Exceptions to this performance target include:

  • Policy-Based Actions: Content that is quarantined, blocked, or delayed due to configured security policies

  • Mail Delivery Loops: Situations where misconfigured routing causes repetitive email handoff

  • Downstream Server Unavailability: Cases where the customer’s mail server is temporarily unreachable or refuses delivery

  • Upstream Notification Delays: Delays in Microsoft 365 or Microsoft Graph delivering subscription-based change notifications that inform MetaDefender for Microsoft 365 that a new Teams message is available for processing.

Monitoring and Reporting

  • Customers may access real-time and historical system metrics via the product dashboard.

  • Outage and maintenance notifications will be published on our status page trust.opswat.com.
