Why organizations choose Valimail. AI has changed email security. Attackers no longer rely only on malicious links or malware; they exploit trust in your brand and domain. Many phishing attacks succeed because criminals impersonate legitimate organizations. They spoof trusted domains and send messages directly to employees, partners, or customers. Traditional email security tools focus on inbound threats, like scanning messages, detecting suspicious links, or training users to recognize attacks. But when someone spoofs your domain and sends messages outside your environment, those emails may never pass through your security stack. That's why sender identity has become the real control point for email security. Domain-based Message Authentication, Reporting, and Conformance (DMARC) helps stop those attacks by authenticating sender identity and giving domain owners control over how unauthenticated messages are handled. But deploying DMARC can be complicated. Many organizations struggle to identify legitimate senders, configure SPF and DKIM, and move safely toward enforcement. Valimail's DMARC platform simplifies the process by helping organizations: * Discover legitimate email senders across their environment * Configure authentication correctly * Monitor authentication results in real time * Move to DMARC enforcement safely The result is stronger protection against exact-domain impersonation without disrupting legitimate email. The result is continuous protection against domain impersonation - and a stronger foundation for trust in every email your organization sends. Thank you to its customers.

Here are some of the reviews ValiMail has received this quarter: Simplifies DMARC Compliance Effortlessly: "I appreciate Valimail's free tier, which offers many basic features that help us get a good start on identifying what mail might be failing SPF and DKIM. Since we're just getting started with DMARC, it's useful in getting the ball rolling and seeing how much work might be needed. The initial setup was very easy as Valimail documented well what needed to be done, and once we updated our DMARC record, information quickly became available to start planning and taking action." - Scott L, Systems Engineer Valimail Delivers Instant Value with Clear, Hands-On Support: "The sales and support teams at Valimail guide you clearly through the product's capabilities and benefits, help you get it set up for use, and troubleshoot any issues along the way. The product itself adds value from the moment it's activated." - Pradeep P., Group IT Director Friendly Interface and Intelligent Identification in Valimail: "I really like the user-friendly interface of Valimail. It transforms a technical and complex protocol into a very visual management of assets. The intelligent identification is extremely useful, saving time by identifying thousands of SaaS services. I no longer need to do detective work to find out who owns the IPs; this eliminates the need for the reverse DNS process to verify if an IP is legitimate or belongs to a cybercriminal. Furthermore, the initial setup was very simple, just requiring the pointing of the SPF and DKIM records to Valimail once in my DNS manager." - Tiago M Your feedback helps improve Valimail and strengthens the broader email authentication ecosystem.
