Castlepoint Cyber Security vs Tanium Reveal: Side-by-Side Comparison (2026)

Castlepoint Cyber Security

Mid-market and enterprise teams drowning in unclassified data across email, cloud storage, and file shares need Castlepoint Cyber Security to actually know what they're protecting. The platform's content-based classification engine handles mixed formats and automatically detects PII, PCI, PHI, and regulated data like CUI without manual tagging, then maps legislative penalties to inform retention policy. Skip this if your data lives almost entirely in structured databases or you're looking for a DLP tool with blocking capabilities; Castlepoint excels at discovery and labeling, not prevention.

Tanium Reveal

Mid-market and enterprise security teams with distributed endpoints and strict compliance obligations should start here; Tanium Reveal finds PII, PHI, and regulated data in place across Windows, Mac, and Linux without staging or copying files, which cuts both discovery time and data movement risk. Pre-built content for GDPR, HIPAA, PCI, and CCPA means you're not building detection rules from scratch, and the SQLite indexing model scales better than some competitors when datasets are large. Skip this if you need cloud-native data classification or heavy integration with your existing DLP stack; Tanium Reveal is endpoint-focused and on-premises only.
