Features, pricing, ratings, and pros & cons — compared head-to-head.
anon.li Drop is a commercial data masking tool by anon.li. Themis is a free data masking tool. Compare features, ratings, integrations, and community reviews side by side to find the best data masking fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Development teams building applications that handle sensitive authentication data or need encryption primitives without vendor lock-in should start with Themis. It's open-source with 1,954 GitHub stars and provides cryptographic services across authentication, storage, and messaging in a single library, letting you avoid piecing together multiple dependencies. The tradeoff: Themis is a low-level building block, not a managed data masking platform; it requires engineering effort to integrate and won't give you the policy engine or compliance reporting that off-the-shelf data masking tools provide.
