archTIS Spirion vs DataStealth Data Discovery: Side-by-Side Comparison (2026)

archTIS Spirion

Mid-market and enterprise security teams drowning in unstructured data across hybrid environments need archTIS Spirion for its 98.5% discovery accuracy and ability to scan both cloud and on-premises systems simultaneously, where most competitors force you to choose. The persistent data labeling and real-time policy enforcement across Microsoft 365 and SharePoint mean you're not just finding sensitive data, you're actually remediating it before exposure happens. Skip this if your organization has minimal cloud footprint or runs primarily on non-Microsoft platforms; the integration depth here is built for enterprises already committed to M365.

DataStealth Data Discovery

Mid-market and enterprise security teams drowning in data sprawl across cloud and on-prem will get immediate value from DataStealth Data Discovery because it actually finds what you've lost track of, not just what's in your inventory. Agentless deployment via DNS means you're scanning in days, not weeks, and the contextual metadata tie-in to system owners and data residency covers the ID.AM and ID.RA gaps most organizations live with. Skip this if you need post-discovery enforcement built in; DataStealth handles finding and classifying sensitive data cleanly, but remediation requires stepping into their tokenization platform.
