Phishing is still the top way attackers breach healthcare organizations—and traditional defenses are failing. Enter Paubox Inbound Email Security, the company’s most ambitious product launch yet. The HIPAA-compliant provider unveiled the generative AI–driven platform today, promising smarter protection for hospitals, clinics, and healthcare IT teams drowning in increasingly sophisticated threats.
Why Healthcare Needs a New Playbook
The numbers paint a bleak picture:
- 89% of healthcare IT leaders say AI is critical for threat detection.
- 95% of phishing attacks go unreported.
- Despite training programs, only 62% of staff can spot phishing emails.
Rule-based filters and semi-annual training sessions simply can’t keep up with adversaries now deploying AI to craft convincing attacks. “Traditional rule-based email security fundamentally doesn’t cut it anymore,” said Hoala Greevy, CEO and Founder of Paubox. “Our generative AI doesn’t just look for known threats—it understands what normal healthcare communication looks like and stops attacks that filters miss entirely.”
Generative AI as a Security Analyst
At its core, Inbound Email Security leverages large language models (LLMs), vector databases, and generative AI to analyze messages in full context. Instead of scanning for suspicious keywords, the system evaluates tone, sender behavior, message intent, and historical patterns.
Each flagged email comes with confidence scores and transparent explanations, giving IT teams visibility that legacy black-box filters don’t provide. Early use cases include blocking fake invoices, detecting domain mismatches, and flagging brand impersonations—all areas where rule-based filters struggle.
Learning and Adapting in Real Time
Unlike static filters, Paubox’s AI continuously learns from both external threats and internal feedback. If security teams flag emails as safe or malicious, the system adapts, aligning with each organization’s unique communication patterns. Over time, this reduces false positives and strengthens accuracy.
Greevy describes it as giving healthcare orgs their own “AI security analyst that works 24/7,” capable of distinguishing a legitimate urgent request from a sophisticated social engineering attempt.
Key Benefits for Healthcare Providers
- Stronger protection against advanced threats like business email compromise and spear phishing.
- Enhanced visibility through AI-generated summaries and clear decision rationales.
- Adaptive learning that improves with organizational feedback.
- HIPAA compliance by design, ensuring patient data stays secure.
Seamless Integration
Inbound Email Security integrates directly with Microsoft 365, Outlook, and Google Workspace, while extending Paubox’s existing inbound protections like ExecProtect spoofing defense, virus scanning, and quarantine reporting.
The product is now available as part of Paubox Email Suite Plus and Premium tiers, with current customers receiving the upgrade automatically.
The Bigger Picture
Generative AI has already shown its power in writing, coding, and automation—but Paubox is betting big on its security potential. In a healthcare sector where phishing attacks can compromise both patient trust and clinical operations, AI-powered defenses may quickly move from nice-to-have to non-negotiable.
