Proofpoint Unveils Innovative Agentic Collaboration Security System to Combat Cyber Threats
SUNNYVALE, Calif. and Proofpoint Protect 2026, San Diego — September 22, 2026 – Proofpoint, Inc., recognized as a global leader in human and agent cybersecurity, has announced the launch of its revolutionary Agentic Collaboration Security system. This groundbreaking initiative integrates an intent-based detection model alongside agentic capabilities, aiming to enhance the security of how individuals communicate and collaborate in the digital landscape.
The Agentic Collaboration Security system is built on a sophisticated reasoning framework, capable of discerning the intent behind interactions. It employs context-awareness to differentiate between malicious activities and legitimate communications, extending its protective mechanisms across email, collaboration tools, and browsing activities.
In an era where the most complex cyberattacks often masquerade as ordinary business activities, the challenge of detection becomes increasingly daunting. Attackers take advantage of compromised suppliers, infiltrating organizations through existing email threads that appear to yield normal exchanges. Fraudulent requests for payments can blend seamlessly into established business relationships, making them harder to identify. Additionally, threats targeting specific executives are often one-off occurrences that do not follow predictable patterns. As artificial intelligence (AI) evolves, it has amplified the volume, speed, and sophistication of these attacks. Given that accounts and requests frequently appear familiar, behavioral anomalies alone may fail to highlight the underlying threats. Thus, detection mechanisms must grasp the broader context surrounding an interaction and comprehend its intent.
Tom Corn, Executive Vice President and General Manager of the Threat Protection Group at Proofpoint, emphasized the changing landscape of cyber threats, stating, "Attackers increasingly operate inside the relationships and workflows organizations already trust. That changes the detection problem. Security needs to understand what an interaction’s goals are, reason over the context, and take action before the attacker succeeds. This must be achieved not through disparate tools, but as one cohesive system that becomes smarter with each decision it makes."
One Shared Foundation for Advanced Security
Central to the Proofpoint Agentic Collaboration Security system is the Proofpoint Knowledge Graph. This innovative framework amalgamates threat intelligence regarding active campaigns, industry-specific attack patterns, and information about compromised suppliers, all while factoring in organizational context, such as business relationships and communication patterns. This builds a holistic understanding of user risk.
The newly introduced Nexus Intent-Based Detection Model leverages this context to conduct multi-stage analyses, adjusting to the nuances of each interaction. Most decisions are made within milliseconds, but when ambiguities arise, the system conducts more in-depth analyses to determine the intended outcome of a message and its plausibility within the established context.
By coupling the Knowledge Graph with the Nexus model, organizations benefit from a shared foundation that enhances detection, investigation, and user protection through a unified approach.
From Intent-Based Detection to Agentic Action
Proofpoint’s advanced capabilities encompass both email gateway and API-based protections. This dual approach allows intent analysis to commence even before message delivery and persist in the inbox, with downstream intelligence continuously reinforcing pre-delivery detection protocols. Notably, Proofpoint stands out as the only secure email gateway capable of delivering intent-based detection prior to user interaction with a message.
Key Features of the System:
-
Intent-Based Detection: This mechanism engages intent reasoning at the email gateway and inbox level through APIs. It is particularly beneficial for individuals with significant access and authority, such as executives, through Privileged User Protection, which builds custom detection models tailored to identify targeted attacks directed at these specific individuals.
-
Autonomous Threat Investigation: The system autonomously reconstructs attack scenarios, identifies associated messages, assesses the extent of impact, and gathers requisite evidence for an organized response. This significantly minimizes the manual effort and time needed to investigate attacks across multiple affected users.
- Adaptive User Protection: Proofpoint continually identifies high-risk users and analyzes the unique risk factors associated with each organization. The system dynamically adapts protection measures and provides real-time coaching to these users, reinforcing security efforts.
Strengthening Protection at the Moment of Interaction
In addition to the aforementioned capabilities, Proofpoint is rolling out Advanced Browser Protection. This represents a comprehensive control point that extends collaboration security beyond traditional gateways and inboxes, focusing on security within the browser itself. Collaboratively developed with Push Security, this feature integrates Proofpoint’s renowned email threat intelligence with browser-native defenses. It aims to mitigate risks such as post-click phishing, malicious URLs, rogue browser extensions, and credential theft.
Browser telemetry is seamlessly incorporated into the Threat Protection Workbench, the Proofpoint Security Graph, and the Investigation Agent, providing security teams with cohesive visibility and investigative workflows that span the entire collaboration attack continuum—from initial message delivery to user interactions within the browser.
Availability
The capabilities of the Proofpoint Agentic Collaboration Security system will be delivered in Q1 2027 as an update to the existing collaboration security solution. This extension of protection is designed to enhance the existing tools without necessitating a migration process. However, availability may vary in regions with specific data residency requirements.
