Mimecast, a global leader in managing human and AI risk, announced that its complete email security protection stack is now available through API deployment, eliminating a fundamental trade-off in the market. Current standalone integrated cloud email security (ICES) solutions offered fast deployment but at a cost: these solutions were built only for targeted, sophisticated attacks, quietly relying on native Microsoft or Google controls to handle the volume of everyday threats.
The just-released Mimecast State of Human Risk 2026 report quantifies the cost of that dependency: 64% of organizations acknowledge that native collaboration tool security controls are insufficient, yet many continue relying on them. The consequences are measurable: 53% report increased phishing volume and 48% see rising business email compromise attacks that native protections and current ICES solutions fail to stop at scale.
Mimecast’s API deployment is engineered to deliver the full detection stack, from deep URL and malware inspection to advanced AI-powered engines, through direct Microsoft 365 integration that deploys in minutes without requiring mail exchange (MX) record changes or mail flow modifications.

Threat Detection Capabilities Delivered Through API Architecture
Mimecast’s AI-driven detection engines have been trained across 24 trillion data points and hardened across 42,000 organizations globally. Customers using Mimecast’s new detection models are catching 3x more business email compromise and credential phishing attacks than traditional detection methods identify — these threats are specifically designed to bypass conventional security.
That detection capability, previously available only through gateway deployment, is now delivered through an API architecture. The API deployment also includes behavioral AI that is engineered to identify patterns across email and identity, along with broad threat protection capabilities that pure-play ICES vendors can’t offer at scale:
- Multi-Vector Threat Protection (MVTP) is built to correlate signals across sender authentication, domain reputation, URLs and content simultaneously, delivering the layered analysis that single-vector ICES engines cannot replicate
- Deep URL Inspection is engineered to deliver time-of-click analysis that catches threats evading pre-delivery scanning
- Advanced BEC Protection is designed to apply modern AI infrastructure across more than 20 languages, detecting impersonation and social engineering at a precision that requires real-world training volume to achieve
- Malware Detection and Active Sandboxing is designed to analyze attachments in isolated environments, catching zero-day threats that signature-based approaches miss
- Account Takeover Protection is engineered to identify post-compromise behavior through identity signal correlation, containing breaches before data leaves the environment
These capabilities are available today through an API architecture that is built to deploy rapidly.
