Microsoft Purview for AI - Pros & Cons
Pros
- ✓Native, agentless integration with Microsoft 365 Copilot, Security Copilot, and Copilot Studio — no separate connectors required for organizations on E5 licensing
- ✓DSPM for AI dashboard provides one-click discovery of risky prompts across both Microsoft Copilot and 100+ third-party AI apps including ChatGPT, Gemini, and DeepSeek
- ✓Sensitivity labels applied to source documents are automatically inherited by Copilot-generated responses, preventing accidental oversharing of confidential data
- ✓Built-in regulatory templates in Compliance Manager cover EU AI Act, NIST AI RMF, ISO 42001, and 300+ other frameworks for enterprise audit readiness
- ✓Tight integration with Microsoft Entra ID, Defender XDR, and Insider Risk Management means existing identity and threat signals enrich AI governance
- ✓eDiscovery and Communication Compliance capture full Copilot prompt/response history for legal hold and HR investigations
Cons
- ✗Effectively requires a Microsoft 365 E5 or E5 Compliance add-on subscription, making per-user costs significantly higher than standalone AI security tools
- ✗Configuration complexity is high — full DSPM for AI deployment typically requires multiple admin roles across Purview, Entra, and Defender portals
- ✗Coverage outside the Microsoft ecosystem is shallower; protecting AWS Bedrock, Google Vertex AI, or self-hosted LLMs requires additional Defender for Cloud Apps tuning
- ✗Some advanced features like Adaptive Protection for AI and certain DSPM signals are still rolling out and gated by region or licensing tier
- ✗The learning curve for non-Microsoft-shop security teams is steep, with documentation spread across Purview, Defender, and Microsoft 365 admin centers
Agent Security Suite - Pros & Cons
Pros
- ✓Broad cross-platform coverage spanning Microsoft Copilot, Salesforce Agentforce, ServiceNow, ChatGPT Enterprise, Google Vertex AI, and Amazon Bedrock in a single control plane
- ✓Three-layered architecture (Observability, AI-SPM, AIDR) maps cleanly to established security disciplines like CSPM and EDR, shortening the learning curve for existing SecOps teams
- ✓Active original research program through Zenity Labs, with named vulnerability disclosures like AgentFlayer and PleaseFix that feed detections back into the product
- ✓Detects shadow AI and citizen-developed agents in low-code environments like Power Platform, which most general-purpose security tools miss entirely
- ✓Industry-specific framing for financial services, government, and healthcare with compliance-oriented controls suited to regulated deployments
- ✓Runtime threat detection goes beyond static posture scanning to catch prompt injection, data exfiltration, and anomalous agent behavior in production
Cons
- ✗Enterprise-only pricing with no published tiers, free trial, or self-serve option — unsuitable for small teams or early-stage experimentation
- ✗Value depends on the breadth of agent platforms you actually run; single-platform shops may find narrower native tooling cheaper
- ✗Agentic AI security is a young category, so detection coverage and false-positive rates are still maturing across the industry, Zenity included
- ✗Requires meaningful integration work and permissioned connections to each agent platform, which can be slow in change-controlled enterprises
- ✗Overlaps with features now appearing natively in Microsoft Purview, Salesforce Shield, and hyperscaler AI guardrails, forcing buyers to justify a dedicated layer
