Features, pricing, ratings, and pros & cons — compared head-to-head.
dotgpg is a free data classification tool. Microsoft Purview Information Protection is a commercial data classification tool by Microsoft. Compare features, ratings, integrations, and community reviews side by side to find the best data classification fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams managing distributed secrets across small engineering organizations will get real value from dotgpg because it treats secrets like code: versioned, diffable, and auditable in git without requiring a dedicated secrets vault. The 167 GitHub stars and free pricing reflect genuine adoption among developers who need password backup without infrastructure overhead. Skip this if your team is already standardized on HashiCorp Vault or AWS Secrets Manager; dotgpg fills a gap for teams too small to justify those systems but too security-conscious to store credentials in plaintext.
Microsoft Purview Information Protection
Mid-market and enterprise teams already deep in Microsoft 365 will find their fastest path to data classification here because Purview classifies and labels at scale without ripping out existing infrastructure. The AI-powered classifiers work across SharePoint, OneDrive, Exchange, and Teams simultaneously, and the exact data match capability catches structured data like credit cards and social security numbers that pattern-matching alone misses. Skip this if your data lives primarily outside Microsoft environments or if you need detection and response for data exfiltration; Purview excels at ID.AM asset discovery and PR.DS labeling but leaves incident investigation to other tools.
