Knowing what an agent can access is only part of the problem. Security teams also need to understand what it's doing with sensitive data, whether that action matches business intent, and when to intervene.

Identity + Data + Intent is becoming the new AI security conversation.

Proofpoint has been named a Pace Setter in Gartner's inaugural 2026 Emerging Market Quadrant™ for AI Application Security – Established Vendors. https://t.co/wgzciI0tGp

We believe this recognition reflects the growing importance of securing AI across the entire enterprise.

Fal.Con put AI agent runtime and identity in the spotlight. Both matter, but authenticated does not always mean aligned. Proofpoint adds the human, intent, email, MCP and data context needed to verify what an agent was asked to do and what it actually did. #AISecurity

Today, through the @OpenAI Daybreak Defense Network, we unveiled the Proofpoint SOC Analyst Agent, an agentic AI capability to help security teams investigate threats and make informed decisions faster. https://t.co/HPUMO2g8zb

A core Proofpoint belief: As attacks accelerate and evolve, securing the #agenticworkspace requires understanding user intent, protecting data, and responding at machine speed.

AI is industrializing trust abuse. Lookalike domains can appear legitimate, Teams messages can impersonate IT, and agents can act at machine speed. Where does trust verification break across email, suppliers, collaboration, data, and AI workflows?

Through a new integration, Proofpoint DLP policies can now be applied to @AnthropicAI’s Claude to block prompts carrying sensitive data in real time. This stops organizations’ data from ever reaching the model.

AI security is no longer just a model problem. It is a data-and-intent problem: who triggered the action, what data the agent touched, which tools it called, and whether the outcome still matched human intent. Secure people, data and agents together. #AgenticAI #Cybersecurity

SecurityWeek reported that the next MCP specification makes the protocol more enterprise-ready but shifts more security responsibility to developers and platform operators.

This reinforces Proofpoint AI MCP Security as a timely conversation.

AI-speed attacks are changing the operating model. Proofpoint adds the human- and agent-centric control layer that reduces phishing, impersonation, account compromise, and data-loss paths before they become SOC workload.

Updates are coming to #DMARC, the cornerstone for domain protection and anti-phishing.

This @Proofpoint blog outlines the emerging specification aimed at making enforcement more reliable at scale. https://t.co/zuhcQYfE6V
