Tenant Risk Exposure Dashboard Tackles Permission and Sharing Risks

The new Tenant Risk Exposure dashboard complements Proofpoint's existing 365 Permission Manager by providing administrators with a visual overview of permission and sharing risks across Microsoft 365 tenants2

2

. Dashboard widgets highlight specific vulnerabilities including anonymous access, external users, organization-wide permissions, public groups, inactive guests, and orphaned accounts2

2

. Each finding includes a shortcut for manual remediation, with automatic remediation also available1

. Daniel Hofmann, general manager and executive vice president of Proofpoint MSP Platform, emphasized that overly broad permissions and unclear sharing settings existed before AI arrived, and using the technology "can amplify their impact"1

Explainability in Email Live Tracking Improves False Positive Resolution

Proofpoint's AI-driven security features now include explainability for email verdicts, helping security teams understand why messages are flagged as suspicious or legitimate2

2

. When reviewing messages in Email Live Tracking, administrators see detailed explanations of how the AI reached its conclusions1

1

. This Explainability in Email Live Tracking feature enables teams to investigate rare false positives more efficiently and consider appropriate remediation measures2

2

. The transparency in email security assessments should accelerate response times when dealing with incorrectly classified messages.

AI-Powered Security Awareness Service Extends to Microsoft Teams

The AI-powered Security Awareness Service now operates within Microsoft Teams through integration with AI.MY, Proofpoint's AI Cyber Assistant2

2

. After employees complete an e-learning session, AI.MY acts as an Awareness Coach, asking three questions tailored to each person's awareness level1

1

. The adaptive training provides immediate feedback, and responses update individual knowledge profiles2

2

. Organizations can use these profiles to measure learning progress and identify employees requiring additional training1

AI Cyber Assistant Agent Streamlines Management for Managed Service Providers

The AI Cyber Assistant Agent integrates directly into the control panel of Proofpoint 365 Total Protection, a Microsoft 365 security suite originally developed by Hornetsecurity1

1

. Partners and administrators receive conversational, AI-powered support for onboarding, configuration, product usage, and security operations2

2

. For managed service providers, the agent helps match products to specific customer needs, translate pain points into recommendations, and identify opportunities to extend protection2

2

. Proofpoint expects this will reduce the effort providers invest in customer consultations1

Expansion Following Hornetsecurity Acquisition

Proofpoint closed its $1.8 billion acquisition of Hornetsecurity in December, then established the MSP unit atop that business in May1

1

. More than 12,000 managed service providers and channel partners now distribute the unit's products to upward of 125,000 customers1

1

. The four new capabilities are scheduled to reach these partners and customers in the fourth quarter1

1

. These updates signal Proofpoint's commitment to helping organizations build secure foundations as they adopt AI tools, addressing both the data and channel access concerns that Hofmann identified as critical alongside tool selection1
