Cars are smarter, more connected and, consequently, more exposed. The digitalization of the automotive industry has opened doors to innovation, efficiency, and comfort, but it has also created a new frontier of risks: cyberattacks. We will address how cybersecurity has become a strategic priority in the automotive sector, what international standards such as ISO/SAE 21434, UNR155 and (UNECE) WP.29 say, and how digital process management can be the first line of defense.

With vehicles increasingly integrated with the internet, smartphones and even urban traffic systems, protecting the vehicle means as much as avoiding mechanical failures. Today, a software loophole can compromise the driver’s steering, brakes, or data. And what was an IT problem is now a critical engineering, quality, and governance issue.
1. What is automotive cybersecurity? And why does she matter so much now?
Automotive cybersecurity is the set of practices, systems, and standards aimed at protecting vehicles against digital threats. These threats can include intrusions into control systems, data theft, remote manipulation of functionalities, and intentional failures caused via software.
With the evolution of Software-Defined Vehicles, the risk grows exponentially:
- Autonomous systems
- OTA (Over-the-Air) Updates
- V2V and V2X communication (vehicle-to-vehicle and vehicle-to-infrastructure)
- Integration with smartphones and third-party apps
2. The standards that are shaping the industry: ISO/SAE 21434 and UNR155
- ISO/SAE 21434: norma internacional que define os requisitos para engenharia de cibersegurança ao longo do ciclo de vida do produto desde a concepção até a desativação do veículo.
- UNR155 (ONU): regulações obrigatórias para homologação de veículos conectados em países da Europa e Ásia. Já afeta montadoras globais e seus fornecedores.
Empresas que não se adequarem a essas normas podem ter produtos barrados em mercados estratégicos.
3. Where does ISOQualitas fit into this scenario?
Digital risk prevention starts with structured management of processes, documentation, and traceability. ISOQualitas PLM is an essential tool for:
- Integrate engineering, quality, and safety on a single platform
- Control specific cybersecurity requirements on each project
- Track critical changes, tests, and validations with secure revision control
- Maintain auditable records of decisions, corrective actions, and protocols
- Facilitate compliance with ISO/SAE 21434, UNR155, WP.29 and standards
4. Cybersecurity starts with engineering
Não se trata apenas de TI: trata-se de garantir, na base do desenvolvimento do produto, que todas as possíveis vulnerabilidades sejam identificadas, controladas e reavaliadas continuamente. A engenharia deve projetar com segurança digital em mente e para isso, precisa de dados, controle e integração.
Um simples atraso na atualização de uma FMEA de projeto ou na documentação de uma mudança de projeto pode abrir uma vulnerabilidade crítica. A ISOQualitas ajuda a evitar isso.
5. Benefits of anticipating cybersecurity in your management
- Lower risk of recalls and failures in the field
- More confidence in negotiating with global automakers
- Preparation for international product approval audits
- Protection of sensitive company and customer data
Cybersecurity is no longer the sole responsibility of IT, it is now part of quality, engineering, and business strategy in the automotive industry. With increasingly connected vehicles, the risk is real and growing. The good news is that with the right digital management, your business can always be one step ahead.
ISOQualitas PLM is the foundation for connecting processes, protecting information, and ensuring that technological innovation comes with security for the product, the customer, and the future of mobility.
