A supplier switch is the process of moving a customer from one energy provider to another. In modern utilities, this often happens through online forms, digital account portals, and automated back-office checks rather than paper paperwork. The switch itself is not a cyber threat, but the digital workflow around it can be abused if identity checks, consent checks, or data handling are weak.
In cyber security, supplier switching matters because attackers may try to hijack a customer account, submit a fraudulent transfer, or use phishing to collect enough personal data to authorize a move. Defenders reduce this risk with strong customer verification, multifactor authentication, secure portals, confirmation notices, audit logs, and fraud monitoring for unusual transfer requests. A well-controlled supplier switch protects both service continuity and sensitive customer information.
