The new system uses generative AI to detect sophisticated phishing and social engineering attacks that traditional filters may miss.
Paubox, a provider of HIPAA-compliant email security, has unveiled its new Inbound Email Security solution, which uses generative artificial intelligence (AI) to protect healthcare organizations against evolving cyber threats. The system is designed to improve upon traditional rule-based filters by analyzing the full context of incoming emails, including tone, sender behavior, and message intent.
Phishing attacks remain the leading cause of email security breaches at healthcare organizations, and conventional security tools are often unable to keep up with sophisticated, AI-generated attacks. According to Paubox, despite regular training, only 62% of healthcare staff can correctly identify phishing emails, leaving organizations vulnerable to data breaches.
“Traditional rule-based email security fundamentally doesn’t cut it anymore when we’re up against AI-generated attacks,” says Hoala Greevy, CEO and founder of Paubox, in a release. “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.”
Contextual Analysis for Threat Detection
Unlike legacy systems that rely on static rule sets, the new solution employs large language models and vector databases to analyze each email. The company reports the system has successfully identified and quarantined phishing attempts, including fake invoice scams and brand impersonation, that other filters missed. For security teams, the platform provides confidence scores and clear explanations for why an email is flagged, aiming to increase visibility and speed up response times.
The system’s AI model is designed to continuously learn from new threats and communication patterns, strengthening defenses as the threat landscape changes without requiring manual updates. It also adapts to an organization’s specific communication patterns as security teams provide feedback on email classifications.
“We’ve essentially given healthcare organizations their own AI security analyst that works 24/7,” Greevy says, in a release. “It understands the nuances of healthcare communication and can distinguish between legitimate urgent requests and sophisticated social engineering attempts.”
The HIPAA-compliant solution integrates with Microsoft 365, Microsoft Outlook, and Google Workspace. Inbound Email Security is now available as part of the Paubox Email Suite Plus and Premium tiers.
