Built by the team at After Dark Systems — engineers who got tired of credentials showing up in Slack messages, Notion pages, and sticky notes.
After Dark Systems has been building infrastructure and security tooling since 2019. Over the years, we kept solving the same problem for clients: secrets scattered across too many places, with no audit trail, no rotation policy, and no way to safely share them across teams.
We built SecretServer.io because existing tools were either too expensive for small teams, too complex to self-host, or too generic to handle the real variety of credential types we see in production environments — disk encryption keys, LDAP bind passwords, code signing certs, and everything in between.
SecretServer.io is a product of After Dark Systems — a managed infrastructure and security company. Our SSO, billing, and support infrastructure runs through the same systems we use for all our managed services clients. When you sign up for SecretServer.io, you're signing into the After Dark Systems platform.
