Kasteon builds carrier-grade security infrastructure—from constrained embedded devices to full enterprise deployments—engineered around open standards, post-quantum cryptography, and zero-trust access control.
Get in touchA deployable platform for organizations that need secure access today, and the underlying libraries for teams building it into their own products.
SDK, Agent, and Gateway that extend carrier-grade 5G authentication and IPsec encryption to any device, on any network—replacing VPN infrastructure, PKI, and carrier integration with SIM-based security that manages itself.
Explore SecureAccess →Post-quantum cryptography, IKEv2/IPsec, and core networking, engineered to run on constrained MCUs—and, from the same codebase, up through Linux, macOS, and Windows. No platform-specific code required in your application layer.
Explore KA Libraries →Every component implements published 3GPP, IETF, and NIST standards—including post-quantum cryptography under FIPS 203/204/205—so systems built on Kasteon interoperate with standards-compliant infrastructure rather than locking you into a proprietary stack.
