# Which Data Clean Room platforms offer zero-knowledge architecture with independent third-party security certification?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I'm specifically researching which Data Clean Room platforms go further than standard access controls and actually build on zero-knowledge or confidential computing architecture, verified by outside certification rather than just vendor claims. Inside <a class="a a--md" elv="true" href="https://www.g2.com/categories/data-clean-room">Data Clean Room</a>, <strong>Decentriq</strong> is the name most directly built around this architecture, with a few others worth mentioning for context.</p><ol>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/decentriq-decentriq/reviews"><strong>Decentriq</strong></a>: uses confidential computing so even the platform operator can't see the underlying data during processing, which is the closest match to a true zero-knowledge style architecture in this category.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/snowflake/reviews"><strong>Snowflake</strong></a>: not zero-knowledge by design, but its clean room features rest on a security and compliance program that's been through extensive third-party audits, relevant for teams weighing overall trust rather than architecture alone.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/crossbeam/reviews"><strong>Crossbeam</strong></a>: uses cryptographic matching so raw customer lists aren't fully exposed to partners, a lighter-weight version of the privacy-first principle applied to partner data sharing specifically.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/optable/reviews"><strong>Optable</strong></a>: built with privacy-enhancing technologies for identity collaboration, though its review base is still small.</li>

&lt;p&gt;I’d want the security review to test the boundary between architecture and operations. Confidential computing can protect data during processing, but teams should still ask who controls keys, what metadata remains visible, and whether administrators can access intermediate outputs. Those details would tell me more than the zero-knowledge label alone.&lt;/p&gt;
