# Which client-side protection systems maintain strong performance while providing endpoint security controls?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I'm researching which client-side protection systems keep strong performance while enforcing security controls, since anything that slows the page tends to get ripped out. Quick note: these tools secure the client-side web layer more than the device endpoint, so I read performance from that.

Oh good question, because some client-side tools add scripts to your pages and you worry about slowing things down. Reflectiz is notable here because it monitors your web pages out-of-band rather than injecting heavy runtime code, so it flags client-side risks without adding page-load overhead, which is a real performance advantage. Feroot Security is also built for client-side protection with an eye on not degrading the user experience. Cloudflare&#39;s approach benefits from running on its global edge network, so protection happens close to the user. To be real, the honest way to judge this is to measure it, run each in a staging environment and check the impact on page-load and Core Web Vitals before rolling to production. Is your concern real-user performance on the site, or overhead on your build and deploy? The monitoring-based tools help most with the former.
