On May 27, 2023, Westamerica Bank experienced a cybersecurity incident that originated at a third‑party vendor rather than within the bank’s own internal systems. The incident unfolded over several days and potentially exposed the personal information of some of the bank’s customers. There was no evidence that the exposed data was subsequently misused. In response to the event, Westamerica Bank notified the affected individuals and offered them complimentary credit monitoring services for one year. The bank emphasized that its internal networks remained secure throughout the episode.

This incident underscores the importance of vendor risk management for financial institutions that rely on external partners for various services. Westamerica Bank’s handling of the breach included timely communication with customers and the provision of protective measures. The episode serves as a reminder of the interconnected nature of modern banking operations and the need for vigilant oversight of third‑party relationships.
