Start from a neutral baseline and add what matters to you. Criteria are labeled by source — the platform baseline is architecture-neutral; buyer-contributed criteria are shown separately.
This evaluation is stored in your browser only. We cannot see it, and it is not tied to any account. Save it to a link or create an account to keep it across devices — you can export it at any time either way.
Signing up adds sharing with your team, sending this as an RFP to vendors, and private document sharing. Nothing above is taken away, and nothing here is sent anywhere until you choose to.
Different techniques suit different use cases (synthetic data for test environments vs. dynamic masking for production query protection); look for a clear match to the buyer's actual use case, not one technique marketed for everything.
Broken referential integrity after masking is the most common real-world failure mode, breaking downstream test/dev environments; look for a demonstrated, customer-referenced example of preserved integrity at realistic complexity.
Synthetic data claiming to be 'private' without a stated re-identification-risk methodology (e.g., differential privacy guarantees) may not actually be privacy-safe — look for a rigorous, named methodology.
Look for automated sensitive-data discovery feeding the masking policy — a masking tool that only works on manually-identified fields misses unknown sensitive data.

Verified buyers can suggest criteria (anonymized before pooling).
Dynamic masking sits in the live query path and can add real latency; look for measured overhead figures under realistic load, not lab conditions.
Look for broad, portable coverage across modern data architectures — a tool limited to traditional relational databases misses a growing share of real data estates.
Not all masking techniques legally qualify as 'anonymization' under every regulation (some remain 'pseudonymization,' which carries different obligations) — look for the vendor being precise about this distinction, not conflating the two.
Look for automated pipeline integration — a masking process that requires manual data-team involvement for every environment refresh becomes a development bottleneck and gets bypassed.
Look for transparent, predictable scaling economics; a vendor unable to project cost at meaningfully larger data volume creates real budget risk for a growing data estate.
This is the core defensibility question for this whole product category — a vendor should provide real evidence (independent testing, published methodology) rather than an unsubstantiated claim of anonymization.
Trend-over-time coverage reporting is a distinct capability from a per-source masking configuration — confirm this exists as a maintained, exportable report.
Look for genuine integration avoiding redundant discovery work; two overlapping tools each independently scanning for sensitive data creates real reconciliation burden.
A reversible tokenization mapping is itself a high-value target — ask specifically about access controls over that mapping, not just the masking process itself.
Over-masking can break legitimate test-environment functionality just as under-masking creates privacy risk — ask for a real accuracy figure and a fast correction workflow for development teams.
Ask for an honest per-environment coverage breakdown; uneven masking coverage across environments is a common real gap a vendor should disclose rather than obscure.
AI training-data masking has distinct scale and utility-preservation requirements from traditional QA/test-environment masking — a vendor should give a specific answer on this increasingly common use case rather than assuming traditional masking capability extends automatically.
