Dispel: Security, For All

Dispel is redefining how the world’s most critical industries connect, protect, and operate. Built for both Operational Technology (OT) and security teams, our Zero Trust Engine delivers secure, scalable connectivity across every make, model, and generation of equipment—enabling fast, reliable remote access, industrial data streaming, and integrated threat monitoring in even the most complex environments.

We don’t just keep operations safe, we make them better. With OTFusion, Dispel unifies applications and systems across sites, streamlining operations, cutting complexity, and driving measurable efficiency gains.

Since 2015, we’ve been pioneering cybersecurity innovation: inventing network-level Moving Target Defense (MTD), securing 54 million utility users worldwide, protecting over $500B in manufactured goods annually, and ensuring the everyday essentials people rely on—from 50% of the U.S. baby formula supply to 1 in 5 non-alcoholic beverages in America—are made and delivered safely.

If you're passionate about providing security, for all, this is the place to be.
