Investors Eye the Weak Spots in Vehicle Cybersecurity

3Lines backs SecureThings to boost real-time cybersecurity as vehicles grow more software-driven

18 Feb 2025

3Lines Venture Capital has invested an undisclosed sum in SecureThings, a cybersecurity company focused on protecting connected vehicles, as carmakers accelerate their shift towards software-led platforms and digital services.

The funding comes as cyber incidents involving connected cars, charging infrastructure and telematics systems continue to increase, exposing weaknesses in existing defences. Automakers have strengthened security in recent years, but the growing complexity of software-defined vehicles has widened the potential attack surface.

SecureThings develops tools that monitor activity across vehicle systems in real time, aiming to detect abnormal behaviour before it disrupts critical functions. The company uses artificial intelligence to analyse data from onboard computers, wireless interfaces and communication links that underpin modern vehicle operations.

As vehicles rely more heavily on over-the-air updates and cloud-based features, the ability to identify and respond quickly to threats has become more important. According to 3Lines, the investment reflects rising demand for security that is embedded across connected platforms rather than added as an afterthought.

Regulators in several major markets are also increasing pressure on manufacturers to demonstrate continuous monitoring and rapid remediation throughout a vehicle’s lifecycle. Analysts say this is pushing the industry towards faster and more adaptive cybersecurity systems that can evolve alongside vehicle software.

While the size of the investment has not been disclosed, it highlights the influence of targeted venture funding in shaping the competitive landscape. Venture capital groups and strategic investors have shown growing interest in vehicle cybersecurity, an area expected to see increased collaboration between automakers and specialist technology providers.

Integrating new security layers into increasingly complex vehicle architectures remains a challenge. However, industry observers say sustained investment and closer partnerships are likely to play a central role in maintaining trust in connected and electric vehicles as adoption grows.

The backing of SecureThings underscores how cybersecurity has become a core consideration in the development of next-generation mobility, alongside performance, safety and emissions.
