Smallstep

Certificate-based device identity platform enforcing that only trusted hardware reaches company resources.

Smallstep issues cryptographic certificates bound to device hardware, so access to networks, applications, and infrastructure can be limited to machines a company actually manages. The approach removes reliance on shared secrets and supports zero trust architectures. The company also maintains the open source step-ca certificate authority tooling. Founded in 2016.
