What platforms does Atlan support?
We have confirmed browser-based access to Atlan. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.
Can Atlan be self-hosted?
We have only confirmed a cloud / SaaS deployment for Atlan, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
What does Atlan integrate with?
We have confirmed 18 integrations for Atlan, including Snowflake, Databricks, BigQuery, Redshift, dbt, Airflow, Tableau and Looker, plus 10 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.

What security certifications does Atlan have?
We have independently confirmed GDPR for Atlan. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Atlan not holding them. Always confirm compliance directly before you rely on it.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Atlan, not the verdict.
