We are Costa, and we make it easy to connect and secure thousands of computers across clouds, on the edge, and everywhere in between.
The future of the $500B, 2030 cyber industry is a unified platform. The big players are moving slowly, trying to integrate legacy services. Costa was built from the ground up to be that unifying platform.
Costa has a unique architecture that is already in path at some of the largest companies in the world.
We are still in stealth. We are backed by Silicon Valley VCs. We have taken companies from inception -> IPO before. And we are laser-focused on solving some of the hardest problems in network security.
