The test here is how much frontend change a tool demands to start working. These are picks from the <a class="a a--md" elv="true" href="https://www.g2.com/categories/client-side-protection">Client-Side Protection</a> category that stood out during my research.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cloudflare-application-security-and-performance/reviews"><strong>Cloudflare Application Security and Performance</strong></a> is easy to slot in for teams already routing traffic through Cloudflare, with reviewers describing smooth integration with existing infrastructure and no added hardware. For those teams, client-side coverage via Page Shield is a configuration step rather than a new deployment, though its reviews focus on the wider platform.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cside/reviews"><strong>cside</strong></a> is repeatedly described by reviewers as a single script tag that goes live in under ten minutes with little to no development effort, monitoring third-party scripts without reworking the frontend. Reviewers note it is a newer product with some rough edges.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/fastly-s-web-application-and-api-security/reviews"><strong>Fastly's Web Application and API Security</strong></a> fits teams that want protection at the edge layer they already operate, with reviewers highlighting customizable rules that configure quickly. It is a WAF and API-first product rather than a dedicated client-side script monitor, and reviewers point to higher pricing and thin documentation.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Does your stack already terminate through a CDN or edge provider you could extend, or would you add a standalone tool? Curious how much frontend change teams here were willing to accept.</p>

&lt;p&gt;I&#39;d lean toward the standalone approach for speed. cside reviewers consistently mention a single script tag and near-zero development effort, which beats the complexity of extending your existing CDN or WAF with new rules. If you&#39;re already on Cloudflare or Fastly, extending is cleaner operationally, but if you&#39;re not, adding a standalone tool keeps your security stack separate and lets you move fast. The tradeoff is that cside is newer with some rough edges, whereas Cloudflare or Fastly integration feels more mature if you&#39;re already invested in those platforms.&lt;/p&gt;
