AI Cybersecurity

A comprehensive approach to AI-powered cybersecurity

AI-powered attacks demand AI-powered defenses

Attackers are using AI to generate phishing campaigns at scale, mimic your executives' writing styles, and orchestrate multi-vector attacks designed to evade single-layer detection. Phishing now accounts for 77% of all attacks — up from 60% in 2024.

Mimecast's Multi-Vector Threat Protection correlates signals across sender authentication, domains, URLs, and content patterns to catch coordinated AI-generated campaigns, backed by intelligence from over two billion emails processed daily across 42,000+ organizations.

AI productivity without the security tradeoff

Your employees are already using AI, with or without IT's blessing. Mimecast gives you real- time visibility into which AI platforms employees are using, what data they're submitting, and where your acceptable use policies are being crossed.

See it, govern it, and enable AI adoption with confidence — without opening the door to data exposure.

Your security team, amplified.

Mihra, the Mimecast Intelligent Human Risk Agent, turns billions of daily signals into clear, actionable intelligence.

The Ask Agent delivers up to 7x faster investigations, giving security teams instant access to insights across their environment. The Investigation Agent brings agentic AI into your security workflows, automatically triaging alerts, summarizing events in context, and recommending next steps — so analysts start every investigation already informed.

And with the Mihra MCP Gateway, your team can bring their own AI tools into Mimecast workflows through a governed integration layer, making investigations conversational without compromising control.
