SSH Keys Don’t Scale. SSH Certificates Do.
- Most teams traditionally use SSH public key authentication which becomes unscalable with more users and hosts, leading to operational and security risks.
- SSH certificate-based authentication offers a more scalable approach and is already used by companies like Meta, Uber, and Google.
- SSH key management sprawl, unclear access boundaries, and maintenance challenges arise with traditional SSH key authentication.
- SSH certificates enable a centralized, auditable, and secure SSH access model with short-lived credentials.
- Setting up SSH certificates requires initial engineering effort but simplifies user access management to hosts.
- SSH certificate-based authentication relies on CA-signed certificates for users and hosts, forming a mutual trust model.
- Users are configured to trust host certificates, and hosts only allow access to users with valid certificates.
- Infisical SSH offers a solution to abstract the complexity of setting up SSH certificate-based access for teams and infrastructure.
- Infisical SSH simplifies the setup process by handling CA management, trust configuration, and SSH certificate issuance.
- Users can register on Infisical SSH to establish secure SSH certificate-based connections with hosts.
