# Which client side protection platform is best for a SaaS company monitoring third-party scripts that are injected by tag managers and could exfiltrate session data?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Tag managers make it easy to inject scripts and hard to see what those scripts do once they run, which is the core risk for a SaaS company worried about session data leaving the browser. These picks from the <a class="a a--md" elv="true" href="https://www.g2.com/categories/client-side-protection">Client-Side Protection</a> category focus on runtime visibility into injected scripts.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/reflectiz/reviews"><strong>Reflectiz</strong></a> (4.7 stars, 32 reviews) is credited by reviewers with continuous visibility into scripts loaded through tag managers and third parties, flagging when a script changes behavior or starts touching sensitive fields. Reviewers note a learning curve to use it fully.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cside/reviews"><strong>cside</strong></a> (4.8 stars, 12 reviews) intercepts every third-party script before it reaches the user and monitors both script behavior and HTTP header changes in real time, which reviewers value for tag-heavy sites. A few mention the dashboard grouping logic takes time to learn.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/jscrambler/reviews"><strong>Jscrambler</strong></a> (4.4 stars, 31 reviews) governs how third-party scripts and sensitive data behave at runtime, and reviewers use it to keep session and form data controlled in the browser before it can be exfiltrated. Reviewers note integration effort depends on how your app ships.</li>

Interested in how SaaS teams here keep marketing's tags from becoming a security gap.</p>

&lt;p&gt;I&#39;ve found the blocking vs. alerting question is really a tension between marketing&#39;s needs and security&#39;s nightmares. For a SaaS company, alerting on change is usually enough if you can respond fast. cside reviewers describe weekly reports and only stepping in when action&#39;s needed, which keeps marketing operational. But if your tag managers let business units add scripts without approval, you probably need inline interception to stop the gap from widening.&lt;/p&gt;
