APAC, 24 October 2025 — Mimecast, a global cybersecurity leader, has announced groundbreaking advancements in AI-powered security at its annual Elevate25 conference, showcasing innovations designed to help organizations transform human risk into measurable resilience.
At the core of its announcement is the introduction of Mimecast’s Mihra AI (Mimecast Intelligent Human Risk Agent), an integrated AI companion that improves threat investigation response times by up to sevenfold, enabling faster, more proactive defense within the company’s Human Risk Command Center.
These updates are a direct response to Mimecast’s 2025 Global Threat Intelligence Report, which found that phishing attacks now account for 77% of all cyberattacks, up from 60% in 2024. The report attributes this surge to cybercriminals increasingly leveraging AI to automate and personalize attacks, underscoring the need for AI-driven defense strategies.
Redefining Security in the AI Age
Mimecast’s latest platform innovations represent a strategic evolution from traditional perimeter defense toward human-centric cybersecurity, integrating AI, behavioral analytics, and automation to empower security teams and employees alike.
“Security teams are drowning in alerts while employees unknowingly create new vulnerabilities through shadow AI,” said Ranjan Singh, Chief Product & Technology Officer at Mimecast. “Our Mimecast AI agents turn hours of investigation into minutes, while simultaneously blocking employees from pasting confidential data into unauthorized GenAI tools. We’re the only platform addressing both sides of the AI risk equation.”
By combining AI-powered threat prediction, self-healing automation, and behavioral intervention, Mimecast aims to deliver adaptive protection — by AI, from AI, and for AI.
Three Layers of AI-Driven Defense
Mimecast’s unified platform introduces a holistic framework to manage modern digital risk:
1. Protection By AI
- Processes over 18 billion security events daily across 42,000 customers, using predictive analytics to pre-empt attacks.
- Mihra AI Agent brings automation and insight across compliance, administration, and investigation. Its Spotlight Agent offers enhanced visibility into collaboration data, improving situational awareness and response.
2. Protection From AI
- Detects and blocks AI-generated phishing and impersonation attacks, capable of mimicking internal communication styles to evade conventional filters.
- Guards against account takeovers, multi-vector threats, and AI-based social engineering tactics across email and collaboration platforms.
3. Protection For AI
- Offers real-time visibility into Generative AI (GenAI) usage within organizations, identifying unauthorized platforms and potential data leaks.
- Detects and prevents Shadow AI, monitoring when employees use unsanctioned AI tools and ensuring compliance with corporate data policies.
Competitive Differentiators: Unified, Intelligent, and Human-Centric
Mimecast distinguishes itself from conventional email-security providers by offering an integrated, AI-native ecosystem that secures email, collaboration tools, and AI activity under a single management console.
Key platform capabilities include:
- Unified Search: One interface to investigate threats across Microsoft 365, Google Workspace, and Slack.
- Behavioral Nudges: Automated user coaching when risky behaviors are detected, coupled with temporary access restrictions.
- DMARC Authentication Upgrade: Enhanced controls for brand protection and domain trust.
- Risk Scorecards: Personalized risk profiling for every employee with automated adaptive security controls.
- Unified Human Risk Management: Cross-platform visibility enabling dynamic control over data-sharing in GenAI applications.
Human-Centric Security as the Next Frontier
Mimecast’s latest innovations build on the company’s Human Risk Command Center, launched earlier this year, which forms the cornerstone of its human-risk intelligence platform.
According to Gartner, by 2027, 50% of large enterprise CISOs will adopt human-centric design principles in security architecture. Mimecast’s approach positions it at the forefront of this shift, turning human behavior from a vulnerability into an asset.
Availability
The new AI-driven capabilities will be rolled out to customers across Q4 2025. Mimecast says its roadmap reflects a sustained commitment to delivering adaptive, intelligent, and unified cyber defense, enabling organizations to thrive safely in an AI-accelerated world.
