"earned ISO/SAE 21434:2021 Automotive Cybersecurity Process Certification"

ISO/SAE 21434 is an international technical standard that specifies how automakers and suppliers must address cybersecurity across a vehicle’s entire life cycle—design, development, production, operation, maintenance and decommissioning. For investors it signals whether a company follows recognized practices to reduce hacking risk, avoid regulatory penalties and limit costly recalls or liability; think of it as a building code for a car’s digital systems that affects product safety, compliance costs and market access.

unece un regulation no. 155 regulatory

"supports compliance with UNECE UN Regulation No. 155"

UN Regulation No. 155 is an international vehicle safety rule that requires car makers to have a documented Cyber Security Management System (CSMS) to identify, assess and manage cybersecurity risks across a vehicle’s lifecycle. Like a building’s fire-safety code for digital systems, it affects type approval and market access by setting mandatory processes, reporting and controls for preventing and responding to hacking or other cyber threats, which influences compliance costs and regulatory risk.

cyber security management system regulatory

"including its Cyber Security Management System (CSMS) requirements"

A cyber security management system is an organized set of policies, processes, technologies and roles that a company uses to identify, protect against, detect, respond to and recover from digital threats. It works like a security plan for a business’s computers and data, coordinating tools, staff training, incident plans and monitoring so risks are managed consistently. Investors care because the system affects the likelihood of costly breaches, regulatory penalties, operational disruption and reputational damage, all of which can influence a company’s value and future cash flow.
