How does Abnormal handle HIPAA compliance requirements?

Abnormal holds SOC 2 Type 2, ISO 27001, ISO 27701, and FedRAMP Moderate certifications. Data is encrypted in transit (TLS 1.2+) and at rest (AES-256). Abnormal executes BAAs and does not use customer data to train models. These controls satisfy healthcare procurement requirements for email security vendors handling adjacent PHI exposure.

Will this cause delays in clinical email workflows?

No. Abnormal connects via API — no MX record changes, no mail routing changes, no inline processing delays. Clinical communications flow normally. Only confirmed threats are remediated post-delivery, typically in under 6 seconds. False positive rates are below 0.003%.

Can Abnormal detect attacks from compromised internal accounts?

Yes. Because Abnormal connects via API rather than sitting in the mail flow, it sees internal-to-internal email traffic that gateway solutions structurally cannot access. This includes lateral phishing from compromised accounts, suspicious mail rule creation, and anomalous sending patterns — critical for protecting PHI-containing communications.

How quickly can we deploy without pulling clinical IT resources offline?

Deployment takes minutes via API integration with Microsoft 365 or Google Workspace. No MX changes, no transport rules, no policy configuration. Elara Caring's CISO described being "ready to turn it on the next day" with no training required for operations staff. Average enterprise customers spend fewer than 30 minutes per week in the portal.

What if Abnormal blocks a legitimate vendor email?

It happens — rarely. With 99.99% detection accuracy (validated at Honeywell across 188,000 attacks), false positives are exceptionally uncommon. When they occur, quarantined messages are easy to release. The system learns from each correction through Detection 360, continuously improving per-tenant accuracy. Clinical and vendor communications are prioritized for precision.

The Challenge

Your Gateway Passes Every Attack That Costs You Millions

Vendor Invoice Fraud Inside Existing Payment Threads

Attackers compromise a medical device supplier's email account and reply within a legitimate purchase order thread with updated wire instructions.

Credential Phishing Disguised as EHR Login Portals

A phishing page mimics your Epic or Cerner SSO portal and arrives via a clean URL with no prior reputation.

Executive Impersonation Targeting Revenue Cycle Teams

An attacker spoofs your CFO's display name and sends an urgent request to the billing director to expedite a vendor

Compromised Internal Accounts Forwarding PHI Externally

A nurse's email account is compromised via a phished credential.

Payroll Diversion Requests Impersonating Physicians

An attacker impersonates a physician and emails HR requesting a direct deposit change.

How It Works

Behavioral AI for Healthcare

Know When Your Vendors Are Compromised

VendorBase builds behavioral profiles for every vendor communicating with your organization — pharma suppliers, staffing agencies, device companies, billing intermediaries.

Compromised Accounts Locked in under 6 Seconds

When a clinician's credentials are phished, Abnormal detects the behavioral deviation — impossible travel, new mail rules, unusual sending patterns — and automatically terminates sessions and forces password resets.

Threats Removed before Clinical Staff Engage

Malicious emails are auto-remediated from inboxes before nurses, billing clerks, or front-desk staff ever see them. No user judgment required. No training dependency. Your workforce stays focused on patient care while behavioral AI handles the threats your gateway delivers.
