Who should implement client-side security solutions?

Any business that needs a strong web presence should think about client-side security. This is very important for e-commerce sites, financial services, healthcare organizations, and companies that handle sensitive customer data. If your website uses client-side scripts (and 98.9% do), you need client-side protection. This is important if you let customers share sensitive information. Even websites where users don’t enter sensitive information but that contain adverts could be a prime target for client-side attacks, as advert networks are essentially distribution networks for malicious client-side JS. It also matters if you accept online payments. You need to follow rules like PCI DSS, GDPR, or HIPAA. Any web environment that allows users to enter sensitive data is a high-value target, and bad actors will look for ways to execute attacks where security is limited, which is often the client-side.
