Understanding Proofpoint

Collaboration Security

Collaboration Security protects employees from attacks that arrive by email and other channels: phishing, business email compromise, account takeover and supplier fraud. Core Email Protection blocks threats before delivery, after delivery and at click time, while Collaboration Security Prime extends AI detection of human targeted attacks across several channels. Email Fraud Defense protects the organisation’s own domains from impersonation with DMARC support, and Account Takeover Protection detects and responds to compromised accounts.

• Secure Email Relay for application generated email
• Messaging Protection for messaging and collaboration tools beyond email
• Email DLP and Encryption
• SSO Password Guard, which alerts on reuse of corporate passwords

Data Security

Data Security is for teams worried about data leaving through careless, compromised or malicious insiders. Enterprise DLP and Cloud DLP apply loss controls across email, cloud, endpoints and SaaS, and Adaptive Email DLP stops misdirected emails and hidden exfiltration. Data Security Posture Management finds and protects sensitive data in cloud and hybrid environments, Insider Threat Management watches for risky behaviour by insiders, and Data Security for AI finds AI data exposure and controls risky prompts and uploads.

Digital Communications Governance

Regulated firms that must retain and supervise communications use Archive, Capture, Discover, Supervision, Automate, Track and Patrol. Automate applies machine learning and GenAI to cut down low risk supervision content, and Prism Investigator uses agentic AI to speed up investigations. The Nuclei Discovery and Archive Suite serves small and medium businesses.

AI Security

AI Security is for organisations that want to adopt AI tools and agents without losing track of what they access. It works in three steps: see which AI apps, users, agents, MCP servers and external services exist; govern prompts, agent actions and app behaviour with context aware policy at runtime; and prove what happened with audit trails that run from a single prompt to a multistep agent workflow.

Identity Threat Defense

Identity Threat Defense finds the identity weaknesses attackers use to move laterally. Shadow Admin Detection finds privileged accounts the PAM tool does not manage, it surfaces forgotten service accounts that carry hidden admin rights, and Automated Risk Cleanup purges cached credentials, fixes misconfigurations and strips unneeded access from endpoints.

Threat Intelligence And Human Risk

Supplier Threat Protection, Active Exploits Protection, Emerging Threats Intelligence and Takedown for fraudulent domains extend threat protection beyond the inbox. The Human Resilience Workbench picks out high risk users and applies targeted controls, and ZenGuide delivers automated, risk based security awareness training. Proofpoint 365 Total Protection packages protection for humans and agents for channel partners.

Satori Agents

Satori Agents take on security operations work such as triaging data security alerts and reviewing user reported emails. Satori MCP Access uses the Model Context Protocol to connect them with third party AI assistants, so analysts can work with them from tools they already use.

Agent Integrity Framework

Proofpoint publishes the Agent Integrity Framework, a maturity model for securing autonomous AI, and has joined data security and AI security into one agentic system that extends AI investigations to Microsoft 365 with insider risk visibility into AI activity.
