Automotive cybersecurity: a strategic issue for fleet managers

The development of embedded technologies, telematics, and SaaS solutions in fleet management represents a major step forward for businesses. It enables real-time tracking, route optimization, predictive maintenance, and the electrification of vehicle fleets, while raising a key issue: automotive cybersecurity, and more specifically the cybersecurity of connected cars, which is essential to ensuring both efficient and secure management.

As soon as a vehicle becomes connected and communicates with a mobile application or online platform, it enters a potentially vulnerable data ecosystem. Fleet management thus becomes not only a technical challenge, but also a strategic one in terms of IT security.

Cyber risks affecting corporate vehicle fleets

Today's cars rely on multiple, often critical, information flows. Here are the main threats facing fleet managers:

• Vehicle hacking via connected interfaces (OEM): Some models allow remote access to mechanical or electronic functions, which can be misused for malicious purposes.
• Theft or falsification of telematics data: Incorrect data can alter decision-making, distort performance analysis, or mask risky behavior.
• User identity theft: In the event of a security breach on the mobile application or web portal, third parties can access sensitive information or even interact with operational modules (maintenance, fines, fuel, etc.).
• Intrusions on poorly protected SaaS platforms: If automated flows are not secure, they can be exploited to create fake work orders, delete files, or disable essential alerts.
• Phishing campaigns targeting fleet managers, particularly via fraudulent ANTAI text messages or emails, imitating official traffic violation notifications and exploiting teams' lack of knowledge to steal access data or spread malware.

These threats are no longer the stuff of science fiction: they are now part of everyday life for fleet managers in digitalized environments.

Strengthening automotive cybersecurity for your fleet: best practices

The digital security of a vehicle fleet relies on several technical and organizational pillars. Here are the essential recommendations to follow:

• Host data in an encrypted environment that complies with European standards (GDPR)
• Assign differentiated access rights according to profiles (HR, finance, logistics, management, etc.)
• Implement active monitoring of the platform (alerts in case of suspicious activity)
• Centralize data to avoid vulnerable silos or duplicates
• Use secure connections (HTTPS, strong authentication, etc.) on all interfaces
• Document the history of sensitive operations (complete system log)
• Train employees in best practices (passwords, phishing, public connections, vigilance against fraudulent ANTAI emails, etc.)
