With a deep expertise in cloud, embedded, and automotive systems, we tailor our services & solutions to meet the demands of the rapidly changing connected vehicle and component ecosystem. Every decision on our team is made with passenger safety in mind. 

Our Solutions



Block Harbor has been solving challenges in automotive cybersecurity since 2014. We understand the challenges the automotive industry faces from regulations and standards like ISO/SAE 21434/UNECE WP.29 to developing components with a long supply chain. 


We get it: securing future vehicles comes down to more than just what’s inside the vehicles – it’s all of the related connected infrastructure, too. Cloud computing is an incredible enabling technology for global, scaling infrastructures, and we have years of experience making sure those cloud infrastructure are properly monitored for misconfigurations that might expose assets.


The lowest-level computing components are no stranger to us – from designing security solutions at the hardware layer like the proper use of HSM/TPM, to the related infrastructure such as a PKI to secure updates. We’re ready to implement solutions that work with your system or analyze what you’ve already got.
