Imagine working on a global communication network that’s used by 3.7 billion people and every day more than a quarter trillion messages cross this network. There’s just one problem: Because authentication isn’t built into this platform, nobody can be certain who is sending most of these messages. This gap means that companies are vulnerable to a whole host of attacks on their employees, partners, and customers. Whether it’s wire fraud, W-2 thefts, or “fake news” in an attempt to destroy a brand, companies have been powerless to protect themselves against these impersonation attacks.

Valimail solves this problem. We’ve built a revolutionary platform on top of open standards — DMARC, DKIM, and SPF — that for the first time makes it possible for any organization to protect itself against email impersonation. Valimail pioneered the notion of automated email authentication, with innovative components like our DNS-based Authenticator (including our patented Instant SPF). Our system enables organizations to authenticate their email quickly, easily, and reliably.

We’re committed to building a more trusted email ecosystem by being a leader in Email Authentication as a Service. As part of that commitment, we’re active participants in the open source and standards communities. We’re co-authors of open standards like ARC and BIMI, and contribute to a variety of open source projects that serve the wider community.
