What Cypherbridge Systems does
Cypherbridge Systems is a private, founder-owned embedded security software company founded in 2005 and headquartered in Carlsbad, California. The company develops and licenses portable ANSI C software development kits (SDKs) and toolkits that provide cryptography, secure boot, networking, and connectivity functions for resource-constrained edge devices and IoT products. Its product portfolio — marketed under the SDKPac sub-brand — spans more than fifteen offerings, including the uSSL TLS stack, uSSH server/client, uVPN with IKEv1/v2 and IPsec, uLoadXL secure bootloader with NIST SP800-193 firmware resiliency, uCrypt Suite B cryptographic library, uMQTT, uMODBUS, uSMTP, uFTP, 802.1X, NTP, EST certificate enrollment, XZIP compression, FIDO authentication toolkits, and the AUTOPac AUTOSAR-compatible automotive bundle. Two SaaS services — CDXScan vulnerability management and CDXData edge device/OTA fleet management — extend the portfolio into recurring-revenue compliance tooling positioned around the EU Cyber Resilience Act.
The technology is designed to be portable across major embedded environments: it supports RTOS platforms including Eclipse ThreadX, FreeRTOS, MQX, Linux, and Android; toolchains from IAR, GCC, Keil, Green Hills MULTI, and TI CCS; and semiconductor reference platforms from NXP, Renesas, STMicroelectronics, Texas Instruments, Microchip, and ARM. SDKPac bundles are pre-integrated and tested on partner evaluation kits, enabling customers to drop the security stack directly into projects rather than assembling it themselves.
Cypherbridge sells primarily through enterprise field sales targeting embedded systems manufacturers across industrial control, medical device, automotive, energy, payment, and Mil/Aero verticals, supplemented by DigiKey Marketplace distribution, regional distributors in Europe (SDC Systems, Phaedrus Systems, Indes-IDS, Sightsys, Ultimate Solutions), and semiconductor partner channels. Customers range from venture-funded startups to Fortune 10 global companies. Revenue is generated from one-time SDK licenses, annual maintenance/support contracts, professional design and integration services, and the newer subscription-based CDXScan and CDXData SaaS services. Pricing is quote-based with no public list, supported by a 30-day full-function evaluation program for qualified prospects.
