## Our take

What our shortlists say about the one we picked.

### [Palo Alto Networks Remote Browser Isolation](https://cybersectools.com/tools/palo-alto-networks-remote-browser-isolation)

Best for: Prisma Access customers protecting high-value users from zero-days

RBI is not a replacement for EDR. It protects the browser session from web-delivered threats, but it does not cover file-based malware delivered via email, USB, or other vectors. Think of it as a complement to your endpoint stack for specific high-risk user populations: executives, finance teams, legal, anyone who is a frequent phishing target and whose compromise would be catastrophic. Deploying it universally across all users is expensive and often unnecessary.
