What we offer


Our product SeaCat PKI provides all C-ITS Security and C-V2X Security functions such as Root Certificate Authority, Enrolment Authority (EA), Authorization Authority (AA), and Trust List Manager (TLM) in compliance with ESTI standards TS 103 097 v1.3.1/v1.2.1 and ETSI TS 102 941 v1.3.1.
Certified for participation on ETSI Plugtests.

ITS-S Security Module

ITS-S Security Module is an implementation of the client-side (OBUs, RSUs or back-office) security features of C-ITS and C-V2X. The module can be used as a reference implementation for your projects, as a library for OBU and RSU or as standalone microservice with the API.
Certified for participation on ETSI Plugtests.

Open C-ITS / C-V2X Test PKI

We operate FREE, continuously available, online test PKI for all organizations interested in the implementation of C-ITS Security or C-V2X Security. The environment offers Root CA, Enrolment Authority, Authorization Authority, and Trust List Manager. The environment allows continuous testing of the C-ITS and C-V2X applications.


Thanks to our activities in C-Roads pilots, C-ITS / C-V2X Security workshops, and ETSI plugtests, we have deep expertise and practical experience with C-ITS Security. We offer expert consultancy in C-ITS and C-V2X security from the architecture to implementation and compliance validations.


Learn about C-ITS Security and C-V2X Security standards, requirements, and implementation best-practices. The training will accelerate the adoption of the C-ITS Security and will quickly boost C-ITS Security competency. Participants of the training will receive the certificate of participation.

EU CPOC managed relation

We manage all relations with European Commission C-ITS Point of Contact (CPOC), specifically the participation on the European Certificate Trust List (ECTL) / Trust List Manager (TLM) for your organisation. Thanks to our long term contribution and active cooperation with EU JRC, we ensure that the relationship is managed smoothly and efficiently.
