📊 Industry Insights

Stay ahead of the curve with our analysis of API security trends, developer tool innovations, and best practices from the security community.

Why Zero-Exposure Matters

Traditional key management is risky. API keys stored in .env files, hardcoded in source code, or shared via insecure channels create massive security vulnerabilities.

Zero-exposure key management offers a better way:

• Keys never leave your device unencrypted - Complete local control
• AES-256-GCM encryption with PBKDF2 key derivation (100,000 iterations)
• Automatic detection and secure storage - No manual management needed
• Session-based unlocking - Maximum security with minimal friction
• No cloud storage - Your keys stay on your device, always

Our Mission

At Cirklu, we believe developers deserve security tools that actually work with their workflow, not against it. By combining zero-exposure architecture with intelligent automation, we're making API security effortless.

Traditional password managers weren't built for API keys. They lack context-aware autofill, don't understand API key patterns, and force manual workflows that developers avoid. Cirklu was purpose-built for developers who need fast, secure access to their API keys.

What's Coming

In the coming weeks, you'll find content including:

• Security deep-dives on zero-exposure architecture and encryption
• Integration guides for popular development tools and workflows
• Case studies from developers using Cirklu in production
• Best practices for API key management and security hygiene
• Product tutorials and feature spotlights
