#2. On-Premises Browser Isolation
On-premises browser isolation expertise defends customers the identical manner as distant or cloud-hosted browser isolation does. However the distinction is shopping exercise is hosted on the servers managed by the organizations.
The disadvantage of on-premises browser isolation is that organizations should present their very own servers for browser isolation, which may be pricey.
Additionally, isolation normally occurs throughout the group’s firewall. This implies finish customers’ units are protected against malicious JavaScript, however organizations’ inside networks are at all times in danger.
Due to this fact, choosing distant or cloud-based browser isolation is an clever alternative.
#3. Shopper-Aspect Browser Isolation
Within the client-side browser isolation technique, internet pages/internet apps load, and related JavaScript code executes on the customers’ units however in an remoted setting, utilizing sandboxing or virtualization.
The core idea of browser isolation is predicated on bodily stopping dangerous code from downloading on the system.
