Healthcare’s ultimate multitool for defense against phishing and ransomware

Phishing, BEC, and ransomware pose a serious and chronic threat to organizations in all sectors, but particularly those in healthcare. So what can providers in this sector – and indeed all sectors – do to help protect themselves?

What are DMARC & BIMI with VMC?

DMARC (Domain-based Message Authentication, Reporting, & Conformance) is an email authentication protocol that protects domains from exact impersonation (email spoofing). When implemented at the strongest policy of p=reject, it stops hackers from being able to impersonate your domain and send phishing emails to your employees, customers, and supply chain.

BIMI (Brand Indicators for Message Identification) is a relatively new standard that enables companies to show their registered logo on DMARC authenticated emails.

A VMC (Verified Mark Certificate) is a digital certificate developed by Entrust in cooperation with the BIMI Working Group. VMCs standardize the method for showing verified logos in email and create a more immersive email experience for businesses.

To qualify for BIMI with VMC, a business must be DMARC compliant.

We’ve put together this infographic explaining why DMARC & BIMI with VMC is the ultimate multitool to help healthcare providers and all organizations defend themselves against phishing and ransomware in 2022.
