Impact and Risks of Disabling Cache Shield on Website Performance and Security

  • 1.  Impact and Risks of Disabling Cache Shield on Website Performance and Security

    Posted 03-18-2025 08:59
    A website changes were not reflecting until the cache was purged. I compared the cache settings of the affected website with another site that does not experience this issue. I observed that Cache Shield was enabled for the affected site but disabled for the other.
    I would like to know the potential impact and risks associated with disabling it, considering its role as a protection mechanism and if disabling it will fix the issue of having to purge cache before changes reflect.

    Hi, Saheed.

    The risk depends upon the capability and performance of the origin, or origins (ie: your webservers) on the back end. 

    The Cache Shield is designed to be a single point of requests for resources to your websites, as opposed to the thousands of requests that you will receive from around the world from different Imperva IPs when Cache Shield is disabled.

    In other words, if your webservers can handle the load, it is not a risk.
