Arexdata Data Classification vs Lightbeam Data Classification: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise teams managing data sprawl across on-premises, cloud, and endpoints will get the most from Arexdata Data Classification because it actually tracks sensitive data movement instead of just tagging it at rest. The hybrid deployment model and built-in audit trails across all three environments address NIST ID.AM and PR.DS without requiring separate tools per location. Skip this if your primary concern is detecting exfiltration in motion; Arexdata excels at classification and lifecycle governance, not real-time breach prevention. Mid-market and enterprise teams drowning in unclassified data across clouds and databases should start with Lightbeam Data Classification because its identity-centric approach actually connects who accessed what to what the data contains, eliminating the guesswork that kills most classification projects. The Data Identity Graph automatically tags PCI/PII/PHI across structured and unstructured data while continuously scanning databases without manual effort, addressing the ID.AM and PR.DS gaps that leave most organizations unable to answer basic inventory questions. Skip this if your data lives almost exclusively on-premises in legacy systems; the cloud and SaaS integrations are where Lightbeam's strengths live.
