Paubox Unveils Generative AI-powered Email Security to Combat Evolving Healthcare Cyber Threats

August 29, 2025 at 15:19 PM EDT

Generative AI technology provides healthcare organizations with stronger protection, clear visibility, and reduced manual oversight

Paubox, the leading provider of HIPAA compliant email security, today unveiled its most ambitious product release to date—Inbound Email Security, the AI-powered inbound email security solution that improves upon rule-based filters with generative artificial intelligence.

Phishing attacks remain the top cause of email security breaches at healthcare organizations, and 89% of healthcare IT leaders now identify AI and machine learning as critical for email threat detection. Traditional email security solutions are proving inadequate against sophisticated threats targeting patient data and healthcare operations.

“Traditional rule-based email security fundamentally doesn’t cut it anymore when we’re up against AI-generated attacks,” said Hoala Greevy, CEO and Founder of Paubox. “Inbound Email Security represents the next generation of email security—our generative AI doesn't just look for known threats, it understands what normal healthcare communication looks like and stops sophisticated attacks that filters miss entirely.”

Generative AI technology addresses growing healthcare security challenges

As cyber threats become increasingly sophisticated, healthcare organizations face mounting pressure to protect sensitive patient data while maintaining operational efficiency. While 46% of healthcare IT teams have implemented advanced email filtering to combat the rising tide of phishing attacks, these traditional defenses are crumbling under the weight of increasingly sophisticated threats. The scope of the crisis becomes clear when considering that 95% of phishing attacks are never even reported to security teams—creating a massive blind spot that leaves organizations vulnerable to unknown breaches.

Perhaps most troubling, despite 81% of healthcare leaders conducting email security training twice yearly, only 62% of their staff can actually identify phishing emails. This disconnect between training investment and real-world preparedness reveals a core problem in current security approaches: traditional tools and training methods are failing.

Paubox's Inbound Email Security addresses these challenges with generative AI that analyzes tone, sender behavior, message intent, and historical patterns to identify malicious attacks before they reach user inboxes.

Smarter detection through generative analysis

Unlike legacy email security solutions that rely on static rulesets and outdated threat signatures, Paubox’s Inbound Email Security employs large language models (LLMs), vector databases, and generative AI to analyze each incoming email in full context. The solution provides transparent insights into its decision-making process, offering confidence scores and clear explanations for why emails are flagged as spam.

Inbound Email Security has successfully identified and quarantined sophisticated phishing attempts, including fake invoice scams that traditional filters missed. The AI's ability to detect sender domain mismatches and brand impersonation attempts provides healthcare organizations with a critical defense against data breaches.

Continuous learning and adaptation

Paubox’s Inbound Email Security's AI model continuously learns from new threats and communication patterns, automatically strengthening organizational defenses as the threat landscape evolves. This adaptive approach ensures healthcare organizations stay protected against emerging attack vectors without requiring manual updates or configuration changes.

“We've essentially given healthcare organizations their own AI security analyst that works 24/7,” added Greevy. “It understands the nuances of healthcare communication and can distinguish between legitimate urgent requests and sophisticated social engineering attempts.”

Key benefits for healthcare organizations

Stronger protection: Generative AI goes beyond keyword scanning to understand communication patterns, sender behavior, and message context, providing superior detection of advanced threats including business email compromise, spear phishing, and social engineering attacks.

Enhanced visibility: 69% of security professionals cite easy-to-read AI-generated summaries as a key benefit in threat intelligence. Unlike traditional filters that operate as black boxes, Paubox’s Inbound Email Security provides transparency into its decision-making process. Security teams can review confidence scores and clear explanations for every threat detected, enabling faster response times and more informed security decisions.

Adaptive learning: Inbound Email Security learns from your team's decisions, becoming smarter with every email you flag as safe or spam. As security teams provide feedback on email classifications, the AI adapts to your organization's unique communication patterns and preferences, reducing false positives and improving accuracy over time.

HIPAA compliant by design: Built specifically for healthcare, Paubox’s Inbound Email Security ensures patient data is never shared with third parties, maintaining strict HIPAA compliance while providing the security customers rely on.

Inbound Email Security integrates seamlessly with existing Microsoft 365, Microsoft Outlook and Google Workspace email systems and maintains compatibility with popular Paubox inbound security features including ExecProtect display name spoofing protection, virus and malware scanning, Paubox Transcription, and quarantine reporting.

Inbound Email Security is available immediately as part of Paubox Email Suite Plus and Premium tiers. Existing customers will receive the upgrade automatically, while new customers can begin protecting their organizations today.
