Paubox launches generative AI email security for healthcare

Written by Farah Amod | October 01, 2025

A new AI-powered email defense system is now available to help healthcare organizations combat rising phishing and impersonation threats.

 

What happened

Paubox has released a new generative AI-based product called Inbound Email Security, designed to detect and stop advanced email threats targeting healthcare organizations. The new tool, announced as part of the company’s HIPAA compliant email platform, replaces traditional rule-based filters with AI that analyzes tone, context, and behavior.

CEO Hoala Greevy says that older security methods can’t keep up with AI-generated phishing attacks. Inbound Email Security is designed to learn continuously and detect patterns that static filters miss, offering healthcare teams better protection with less manual oversight.

 

Going deeper

Paubox’s generative AI solution uses large language models and vector databases to analyze the full context of incoming messages. This allows it to detect nuanced attacks like invoice scams, brand impersonation, or domain spoofing threats that frequently bypass conventional filters.

Beyond detection, the product also improves visibility. Security teams receive confidence scores and explanations for flagged emails, making it easier to evaluate and respond to threats. The system adapts over time based on user feedback, enabling it to better distinguish between legitimate internal messages and suspicious activity.

 

The big picture

Greevy describes the new tool as “an AI security analyst that works 24/7,” built specifically to understand healthcare communication. The product is fully HIPAA compliant and does not share data with third parties. It integrates with Microsoft 365, Google Workspace, and existing Paubox features like ExecProtect, malware scanning, and transcription services.

According to Paubox, the AI model learns with each email flagged as safe or suspicious, adapting to organizational communication habits while reducing false positives.

 

FAQs

How does generative AI differ from traditional rule-based email filters?

Generative AI evaluates the context, tone, sender behavior, and intent of emails, rather than relying on static rules or keyword lists. This allows it to detect previously unknown threats.

 

Can Paubox Inbound Email Security be customized to specific organizations?

Yes. The system adapts to an organization’s communication patterns over time, learning from manual classifications of spam and safe emails.

 

Does the AI model require manual updates to stay effective?

No. It updates automatically as it processes new threats, reducing IT teams' need for ongoing configuration or patching.

 

What makes this solution HIPAA compliant?

The platform is built exclusively for healthcare use, and Paubox does not share any patient data with third parties. It also operates within the security frameworks required for HIPAA compliance.

 

Is this product only available to new customers?
