More About Valimail
Valimail provides email authentication services that help enterprises, public-sector organizations, and service providers implement and manage DMARC, SPF, and DKIM to secure their outbound domains and protect recipients from spoofed or fraudulent email. The company focuses on giving security, IT, and messaging teams a controlled way to deploy domain-based authentication at scale without relying on manual Domain Name System (DNS) management.
Valimail’s core offerings System Integration Testing (SIT) in the email security and identity management categories and are designed to work alongside existing secure email gateways, cloud email providers, and security stacks. Its services use DNS-based records to assert domain ownership and authenticate messages, enabling organizations to define and enforce policies for how receiving mail servers handle unauthenticated email. Through this model, Valimail targets domain spoofing, Business Email Compromise (BEC) vectors that rely on lookalike sender identities, and other abuses of brand domains in email headers.
Technically, Valimail centers its platform on internet standards including Domain-based Message Authentication, Reporting, and Conformance (DMARC), Sender Policy Framework (SPF), and DomainKeys Identified Mail (DKIM). The platform automates discovery of sending services that use an organization’s domains, assists with provisioning and maintenance of DNS records for these protocols, and provides reporting that aggregates authentication results from receiving mail systems. This feedback loop allows administrators to understand which senders are aligned with policy and which are failing authentication.
The company’s tools provide dashboards and workflows that guide organizations from monitoring-only DMARC policies toward stricter enforcement states such as quarantine or reject, reducing spoofed email that appears to originate from protected domains. By handling complex SPF record management and DKIM key alignment on behalf of customers, Valimail aims to reduce misconfiguration risk that can affect message deliverability or expose gaps in authentication coverage. Integration with cloud-based email providers and third-party sending services supports use in multi-domain, multi-SaaS environments typical of larger enterprises.
Within an enterprise technology directory, Valimail is categorized under email security, identity and access for email identities, and domain protection. Its platform is used by Security Operations (SecOps) teams, email administrators, and risk and compliance functions that require authenticated email flows for phishing defense, brand and domain protection, and adherence to policies that call for DMARC enforcement on organizational domains.
