FleetWave Hit by Major Cybersecurity Outage in UK and US Chevin Fleet Solutions, provider of the FleetWave SaaS platform, has taken portions of its system offline following a cybersecurity incident, triggering a "major outage" for customers in the UK and US. The disruption, first acknowledged on April 3, led the company to proactively shut down Azure-hosted environments in both regions as a precautionary measure. FleetWave, a critical tool for managing vehicle fleets, drivers, maintenance, and logistics, supports day-to-day operations for organizations across transportation and emergency services. The outage has left users without access to essential systems, though Chevin has kept some EU and Australian infrastructure online, suggesting a targeted or phased response. In a customer email obtained by The Register, Chevin confirmed it is working with external cybersecurity specialists to analyze artifacts, hunt for threats, and reinforce security controls. However, the company has provided no details on the nature of the incident, whether customer data was compromised, or what triggered the shutdown. A public update on restoration timelines is expected by April 10. The lack of transparency has left affected customers including organizations like Shropshire Fire and Cox Enterprises in the dark about potential risks. While Chevin has not disclosed whether the attack was broad or targeted, fleet management platforms are high-value targets due to their access to operational and commercial data. A breach in one tenant could have cascading effects across multiple users. Chevin has not responded to media inquiries, and customers remain without clarity on whether they were directly impacted. The incident underscores the operational and security challenges of centralized SaaS platforms in critical industries.
