Products and Services

Based on Valimail's IDEA platform and built to support the global standard DMARC (Domain-based Message Authentication, Reporting & Conformance), Valimail Enforce™ addresses the ongoing operational challenges of email authentication with true automation. Valimail’s cloud-based authentication system guarantees customers get to DMARC policy enforcement — and keeps them there. Valimail has patented technology that addresses the organizational and technological hurdles to enforcement and offers the Valimail Enforcement Guarantee™. Valimail Enforce is an FedRAMP-authorized email authentication service and, because it uses no personally identifiable information (PII), it is also GDPR compliant. In 2018, Valimail announced its newest product, Valimail Defend™. Valimail Defend provides immediate, highly accurate, and effective email fraud protection, eliminating inbound email impersonation attacks, including friendly-from spoofing as well as lookalike-domain attacks. Valimail Defend is an automated, identity-driven solution that reliably blocks inbound impersonation emails. In addition, Defend generates actionable threat intelligence for take-down efforts and integration with other customer systems. Valimail Defend complements the company's existing automated email authentication solution, Valimail EnforceTM, to provide a complete, 360-degree defense against email fraud and impersonation attacks, without using personally identifiable information and protected health information. This simplifies compliance with data privacy standards such as HIPAA, GDPR, and more.
