Your security controls stop at the edge of the browser.
Info-Tech Research Group examines what changes when policy moves inside the rendering engine, and how to judge whether your risk concentrates there.
Key findings in this report
A decade of security investment went to the layers around the browser: secure web gateways, CASB, ZTNA, DLP, EDR. The browser itself stayed a consumer artifact, instrumented from the outside.
Proxy-based decryption handles URLs and categories. It cannot reach the rendered DOM, intercept clipboard events, or block a single page element, and SSL interception keeps getting harder against TLS 1.3 and certificate pinning.
Island terminates TLS at the endpoint, so policy applies to decrypted application content where it arrives in plaintext. Rivera calls this true Layer 7 visibility, and it is the structural reason the category exists.
BYOD scalability is the consequence Rivera flags as most important to buyers. The browser becomes the posture and policy surface that travels with the user, with no dependency on MDM enrollment or hardware-linked identity.
Network controls can block an AI tool at the URL level, which pushes users to the next one. Rendering-layer controls apply policy to the prompt itself, including logging, PII redaction before submission, and separation between corporate and personal AI sessions.
What you’ll learn
Rivera walks through how Island works at the rendering layer, which parts of a layered web access stack it can genuinely substitute, and how it compares with proxy-based ZTNA and remote browser isolation on the controls that matter in SaaS-first environments.
The report is equally direct about limits. You'll get named strong-fit profiles, from contractor-heavy workforces to organizations running VDI purely for browser security, alongside the cases that call for augmentation or a different tool entirely, plus the two constraints every buyer should weigh before standardizing on a non-default browser.
