In finance, protecting customer data isn’t just good practice. It’s a regulatory mandate. The SEC’s Regulation S-P (Privacy of Consumer Financial Information) requires financial firms to guard against unauthorized access, maintain robust data-disposal practices, and have a formal incident response program.

A new class of AI-powered browsers are rewriting the rules of data security. While CISOs focus on traditional vectors, employees are unknowingly creating permanent backdoors to your most sensitive data through browsers that remember everything, sync everywhere, and share it all with AI models. The bottom line: If you're not actively protecting against AI browser exfiltration, you're already leaking data. Here's why it's happening, what it costs, and how to stop it today.

As organizations evaluate modern DLP solutions, the gap between vendor promises and operational reality becomes critical.
