Release notes and updates indicate ongoing feature expansion, including granular file transfer controls, expanded custom file type support, and additional platform support across different OS distributions.
Important scope note: Review platforms typically focus on Prisma Access / Prisma SASE rather than RBI as a separately reviewed SKU. RBI sentiment is therefore inferred from:
G2’s Prisma Access reviews include both positive and negative signals:
RBI itself is not the primary review unit on these platforms, but these platform-level issues affect RBI when deployed within Prisma Access.
Search attempts for Palo Alto remote browser isolation on Hacker News did not surface high-signal discussions specific to RBI in the retrieved results.
Palo Alto provides vendor materials including datasheets describing execution approaches and deployment services details.
Limitations: No independently validated RBI-specific ROI case studies with transparent methodology were found in publicly accessible sources. Outcome claims in vendor materials should be validated through independent references or a customer-provided proof of concept.
Community threads offer operational narratives, for example scenarios where Prisma Access scaling issues were mitigated by adjusting virtual firewall instance counts and autoscaling settings. These signals indicate performance can be sensitive to architecture and capacity planning, which is relevant for RBI deployments that route browsing traffic through cloud isolation infrastructure.
A suitable fit is typically:
Likely fits include financial services, healthcare, government, defense, critical infrastructure, and other sectors with elevated phishing and zero-day risk concerns.

Gartner Peer Insights for Prisma Access contains several reviews and reflects a generally positive-to-moderate overall rating. Common themes:
Direct RBI-specific quotes were not observed; Gartner reviews are for Prisma Access overall.
Community threads reveal recurring themes relevant to RBI adoption:
Palo Alto Networks Remote Browser Isolation (RBI) is a cloud-delivered web isolation capability that executes browsing sessions in a remote, isolated environment and streams a rendering back to the user, with the goal of preventing active web content (scripts/exploits) from executing on endpoints. Palo Alto positions RBI as an additional control layer for unknown or high-risk web traffic—particularly for zero-day web threats—while aiming to preserve a user experience similar to native browsing.
In practice, RBI is typically deployed as part of Prisma Access / Prisma SASE (SSE/SASE stack) and is enforced via policy (for example, URL category-based redirection to isolation) with per-session controls (download/upload/copy/paste/print restrictions). Palo Alto supports integrating Prisma Access with third-party RBI providers (Ericom, Menlo) via its URL Access Management / URL filtering redirect workflow, but notes that Palo Alto’s native RBI cannot be run simultaneously with a third-party RBI provider for isolation.
Target: mid-market to large enterprises and regulated organizations that:
Positioning: Palo Alto describes its RBI as designed to reduce classic RBI tradeoffs (such as latency and page compatibility issues) by combining multiple isolation techniques and integrating with SASE policy and logging.
