Publisher review
Lyo, built by Relyance AI, is marketed as the first autonomous data defense engineer designed to monitor and secure how AI agents interact with enterprise data. It targets security and data governance teams who need real-time visibility into AI-driven data flows, especially as organizations adopt multiple AI agents that access sensitive information. Unlike traditional data security tools that rely on periodic scanning, Lyo continuously tracks data activity across cloud, SaaS, and AI environments, attaching business and behavioral context to every interaction. This makes it suitable for enterprises grappling with the complexity of AI agent ecosystems, where understanding data lineage and usage patterns is critical for compliance and risk management.
Lyo operates by mapping relationships between AI agents and data assets to identify risky combinations, such as an agent with broad permissions accessing highly sensitive data. It categorizes data sensitivity levels—for example, flagging personally identifiable information (PII) or financial records—and monitors data flows in real time. The platform provides continuous threat monitoring with proactive alerting, and includes a natural language query interface that allows users to ask questions like "Which AI agents accessed customer data in the last hour?" Additionally, Lyo identifies and monitors vendor-supplied AI components, helping organizations track third-party AI tools embedded in their workflows. Powered by Relyance's AI Data Journeys™, the system attaches behavioral context to data activity, addressing the challenge of understanding dynamic AI environments that legacy scanning tools were never designed to handle.
Lyo competes in the data security and privacy market against established vendors like BigID, Osano, TrustArc, Ketch, and Transcend. While BigID focuses on data discovery and classification across cloud, SaaS, and AI systems, Lyo differentiates by offering an autonomous defense engineer specifically for AI agent interactions. Osano and TrustArc emphasize consent management and privacy workflows, whereas Lyo prioritizes real-time monitoring and relationship mapping. Ketch and Transcend offer automation for data subject requests and compliance, but Lyo's unique value lies in its AI-specific visibility—closing the gap between threat detection and action in environments where AI agents are constantly accessing and moving data.
However, Lyo has notable trade-offs. Its narrow focus on AI agent interactions means it may not replace broader data security platforms for organizations needing comprehensive data loss prevention or endpoint security. The tool is relatively new and lacks the extensive third-party integrations and community support that more mature competitors like BigID offer. Pricing is not publicly disclosed, which could complicate budget planning for enterprises. Additionally, Relyance AI itself has a mixed employee rating of 2.5 out of 5 stars on Glassdoor based on 48 reviews, with concerns about leadership communication and career growth, which may affect long-term product support and development stability.
How it works
-
AI agent monitoring
Monitors and secures how AI agents interact with enterprise data in real time, tracking every access and data movement.
-
Unified asset visibility
Provides comprehensive visibility into both AI and non-AI assets, including cloud, SaaS, and on-premises systems.
-
Risk relationship mapping
Maps relationships between AI agents and data assets to identify risky combinations, such as overprivileged agents accessing sensitive data.
-
Data sensitivity categorization
Categorizes data sensitivity levels (e.g., PII, financial records) and tracks data flows across environments.
-
Continuous threat monitoring
Continuously monitors for threats with proactive alerting, enabling immediate response to suspicious activity.
-
Natural language query interface
Answers questions via a natural language query interface, allowing users to ask about data access and agent behavior in plain English.
-
Vendor AI component tracking
Identifies and monitors vendor-supplied AI components, helping manage third-party AI risks embedded in workflows.
Strengths and trade-offs
Strengths
- Closes the gap between threat detection and action by autonomously responding to risky AI agent behaviors in real time.
- Provides unified visibility into both AI and non-AI assets, covering cloud, SaaS, and on-premises environments in a single dashboard.
- Maps relationships between AI agents and data assets to identify risky combinations, such as an agent with broad permissions accessing sensitive data.
- Categorizes data sensitivity levels and tracks data flows continuously, unlike legacy tools that rely on periodic scans.
Trade-offs
- Focuses exclusively on AI agent interactions, so it may not replace broader data security platforms for general data loss prevention or endpoint security.
- Pricing is not publicly disclosed, making it difficult for enterprises to budget without engaging in sales conversations.
- Relyance AI has a low employee rating of 2.5 out of 5 stars on Glassdoor, with concerns about leadership communication and career growth that could affect product support.
- As a relatively new product, Lyo lacks the extensive third-party integrations and community ecosystem of more mature competitors like BigID.

Getting started with Lyo
-
Sign up for Lyo
Visit the Relyance AI website and request a demo or trial for Lyo. Provide your enterprise email and details about your AI agent environment. A sales representative will contact you to set up your account and provide access credentials.
-
Connect data sources
In the Lyo dashboard, add your cloud, SaaS, and on-premises data sources by providing API keys or service account credentials. Configure connections for each environment to enable continuous monitoring of data flows and AI agent interactions.
-
Define data sensitivity rules
Set up data sensitivity categories by specifying patterns for PII, financial records, or other sensitive data types. Use the built-in classifiers or upload custom regex patterns to ensure Lyo accurately tags and tracks data across your assets.
-
Map AI agent relationships
Use the risk relationship mapping feature to link AI agents to the data assets they access. Review the automatically generated maps and adjust permissions or alert thresholds for any agent-asset combinations flagged as high-risk.
-
Run a natural language query
In the query interface, type a question like "Which AI agents accessed customer data in the last hour?" Lyo will return a list of agents, data accessed, and timestamps. Use this to verify monitoring and investigate any anomalies.
Frequently Asked Questions
What is Lyo and how does it secure AI agents?
