Identity & Security
Automated Private PKI with Caddy & Smallstep
Stop managing spreadsheets of internal certificates. We build automated, identity-based encryption pipelines using Caddy as the edge and Smallstep as the private Authority.
Zero-Trust Internal Communication
Encryption shouldn't be hard. We make mTLS the default, not the exception.
Leverage the ACME protocol internally. Caddy talks to Smallstep to renew certs automatically without human intervention.
Certificates are issued based on cryptographically proven identity, ensuring only authorized services can talk to each other.
Reduce your blast radius. We configure systems to use certificates that expire in hours, not years, minimizing risk.
The Step-CA Workflow
Smallstep acts as your internal Let's Encrypt. By deploying a private CA, your internal microservices gain the same high-grade encryption as your public-facing websites.
- →Root CA Isolation: We keep your root keys offline and secure, using intermediate authorities for daily issuance.
- →Seamless Trust: Automatically distribute root certificates to all your containers and servers.
Zero-Trust Roadmap
Moving to internal mTLS is a journey. Our structured approach ensures your services stay online while we tighten the security perimeters.
Declarative mTLS
Configuring internal encryption shouldn't require hundreds of lines of code. With Caddy and Smallstep, it’s a simple block that handles the heavy lifting of key exchange and rotation.
- ✓ No more manual certificates or key file management
- ✓ Automated OCSP stapling for private domains
- ✓ Industry-standard Elliptic Curve (ECDSA) support
