Paubox, a leader in HIPAA-compliant email security for healthcare, has launched Inbound Email Security, a new generative AI-powered solution designed to combat increasingly sophisticated cyber threats targeting patient data and healthcare operations. The platform marks a significant advancement in email security by moving beyond traditional rule-based filtering methods that are no longer effective against AI-generated attacks. Hoala Greevy, CEO and Founder of Paubox, emphasized the growing inadequacy of legacy systems. “Traditional rule-based email security fundamentally doesn’t cut it anymore when we’re up against AI-generated attacks,” she said. “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.” Phishing remains the top cause of email security breaches in healthcare, with 89% of IT leaders now viewing AI and machine learning as essential for detecting threats. Despite this, many organizations still struggle. A staggering 95% of phishing attacks go unreported to security teams, creating blind spots that attackers exploit. Even with regular training—81% of leaders conduct it twice a year—only 62% of staff can reliably identify phishing emails, highlighting a gap between training and real-world effectiveness. Paubox’s Inbound Email Security leverages large language models, vector databases, and generative AI to analyze incoming emails in full context. It evaluates tone, sender behavior, message intent, and historical communication patterns to detect malicious activity. Unlike traditional systems that rely on static rules and outdated signatures, this AI-driven approach identifies threats such as fake invoice scams and brand impersonation attempts that evade conventional filters. The solution provides transparency by delivering confidence scores and clear explanations for each flagged email, helping security teams make faster, more informed decisions. This feature is particularly valuable, as 69% of security professionals cite easy-to-understand AI summaries as a key benefit in threat intelligence. The system continuously learns from new threats and user feedback, adapting automatically to evolving attack tactics. When security teams mark emails as safe or spam, the AI refines its understanding of the organization’s unique communication patterns, reducing false positives and improving accuracy over time. Built for healthcare, the solution is HIPAA compliant by design, ensuring patient data is never shared with third parties. It integrates seamlessly with Microsoft 365, Outlook, and Google Workspace, and works alongside existing Paubox features like ExecProtect for display name spoofing protection, malware scanning, transcription, and quarantine reporting. Inbound Email Security is now available as part of the Paubox Email Suite Plus and Premium tiers. Existing customers will receive the update automatically, while new customers can begin deployment immediately. Paubox, founded in 2015, is trusted by over 7,000 healthcare organizations, including Cost Plus Drugs, Covenant Health, Devry University, and Oura Ring. According to G2 rankings, Paubox leads in multiple categories, including Best Secure Email Gateway, Email Security, and HIPAA Compliant Messaging Software, and is the only HIPAA-compliant email provider listed on G2’s 2025 Best Healthcare Software Products.
