Netallion AI Assurance vs Microsoft Purview
Microsoft Purview is a broad compliance and data governance suite -- DLP, information protection, insider risk, eDiscovery, and more. It covers a broad compliance surface, with secret detection and AI-specific security a smaller part of its scope. Netallion AI Assurance is the purpose-built control plane for agentic AI governance -- it governs AI agents, MCP servers, and machine identities, with 467 detection patterns, 20 live verifiers, one-click remediation, and NHI lifecycle management. Different scope, complementary strengths.

Choose the Right Tool
Choose Netallion AI Assurance if...
- You need deep secret detection with live verification (not just pattern matching)
- NHI lifecycle management -- discovery, rotation, and decommission -- is critical
- You need to scan Azure Monitor logs, GitHub/GitLab repos, or non-Microsoft collaboration tools
- AI agent governance, MCP trust scoring, and prompt DLP are requirements
- You want one-click remediation into Key Vault, GitHub, or AWS
- You need a purpose-built tool alongside Purview for defence in depth
Choose Microsoft Purview if...
- Your primary needs are DLP, information protection, and data labelling across M365
- You need insider risk management and communication compliance
- eDiscovery, legal hold, and data lifecycle management are priorities
- You want a single vendor for compliance across the Microsoft ecosystem
- You already have M365 E5 and want to maximise existing licences
- Secret detection and AI security depth are secondary concerns
Frequently Asked Questions
Isn't Purview included with Microsoft 365?
Some Purview features are bundled with M365 E5 or as add-ons. Purview's secret detection uses its Sensitive Information Types (SITs) -- pattern, keyword, and checksum matching with confidence levels. Netallion AI Assurance adds 467 specialised secret detectors with live verification that tests whether a detected credential is still active. Many organisations use both -- Purview for broad data governance and Netallion AI Assurance for deep secret and AI security.
Does Netallion AI Assurance replace Purview?
No -- they serve different primary purposes. Purview is a broad compliance and data governance suite (DLP, information protection, insider risk, eDiscovery). Netallion AI Assurance is purpose-built for secret detection, AI security, and NHI lifecycle management. They complement each other. See our Purview Gap Report for a detailed analysis.
Can Netallion AI Assurance integrate with Purview?
Yes. Netallion AI Assurance can ingest findings from Microsoft Purview and enrich them with live verification, remediation workflows, and compliance evidence. The platform also adds Azure Monitor log scanning as a purpose-built surface.
How does detection accuracy compare?
Netallion AI Assurance uses BPE tokenisation to catch generic secrets that regex- and entropy-only scanners miss, then runs 20 live verifiers that test each detected secret against its provider API to confirm it is still active before alerting -- so you triage confirmed-active credentials, not dead tokens. Purview's SIT-based detection relies on pattern, keyword, and checksum matching with confidence levels -- it classifies data rather than testing a detected credential against its provider API.
What about pricing?
Purview features are typically bundled with Microsoft 365 E5 ($57/user/month for the full suite) or available as standalone add-ons. Netallion AI Assurance offers a free tier, Essentials at $149/month, Business at $499/month ($399/month annual), and Enterprise from $1,499/month (sales-assisted), with a 14-day Business trial on all paid plans. Enterprise+ is custom-priced for MSSP and large organizations. For organisations already on M365 E5, adding Netallion AI Assurance provides deep secret detection and AI security alongside the existing stack.
Adding Netallion AI Assurance alongside Purview
Augmentation in 3 steps
Most organisations keep Purview for DLP and data governance while adding Netallion AI Assurance for deep secret detection and AI security. Here is how:
- Connect Azure Monitor and repos -- Link your Log Analytics workspaces, GitHub/GitLab repos, and collaboration tools. The onboarding wizard takes under 15 minutes.
- Review the Purview Gap Report -- Run the Purview Gap Report to review differences in detection and control coverage between SIT-based classification and Netallion's specialised patterns with live verification.
- Enable remediation and compliance -- Turn on one-click remediation, NHI lifecycle policies, and compliance evidence generation to extend coverage into agentic AI governance, non-human identity, and remediation.
