Walseth AI vs Zenity: Structural Prevention vs Runtime Detection
Zenity raised $59.5M to build runtime detection for AI agent governance. We took a different path: structural enforcement that prevents violations before they happen. Here is how the two approaches compare for enterprise teams evaluating AI governance solutions.
Head-to-Head Comparison
| Dimension | Walseth AI | Zenity |
|---|---|---|
| Approach | Prevent-by-construction at build time. Violations are structurally eliminated before code ships. | Runtime detection and response. Violations are identified and intercepted in production. |
| Cost Model | O(constraints) -- cost scales with the number of governance rules, not attack vectors. | O(threats) -- cost grows with every new attack vector and agent behavior pattern. |
| Deployment Model | CI/CD integration. Hooks, tests, and templates enforced in the development pipeline. | SaaS platform with agent-as-identity model. Deployed as a detection layer over production systems. |
| Compliance Support | EU AI Act, NIST AI RMF, SOC 2 mapping. Enforcement evidence generated at build time. | FedRAMP "In Process" authorization. Microsoft partnership for enterprise identity integration. |
| Enforcement Depth | 5-level enforcement ladder: L1 (prose) through L5 (automated hooks). Each level compounds. | Policy-based detection with agent identity tracking. Enforcement happens at the runtime boundary. |
| Funding | Bootstrapped | $59.5M Series B (2025) |
The Detection Treadmill: Why Runtime-First Governance Has a Scaling Problem
Zenity built its platform around the agent-as-identity model: treat each AI agent like a user, track its permissions, monitor its behavior, detect anomalies. This mirrors how traditional identity and access management (IAM) works for human users. Their Microsoft Head of AI Security partnership reinforces this approach -- extend Entra ID to cover non-human identities.
The problem is that agents are not users. Human users have relatively stable behavior patterns. AI agents have combinatorial behavior spaces that grow with every new tool, every new context window, every new model version. Runtime detection must keep pace with this expanding surface, which means every new capability your agents gain increases your detection burden.
Structural enforcement sidesteps this entirely. Instead of detecting violations after they occur, we encode constraints that make violations impossible at the development layer. The cost does not increase with agent complexity because the constraints are fixed at build time. Read more about why this distinction matters in Why Detection-Based AI Governance Fails.
FedRAMP vs Enforcement Ladders: Different Compliance Strategies
Zenity is pursuing FedRAMP "In Process" authorization, which positions them for federal and regulated enterprise sales. FedRAMP certifies that the platform itself meets security standards -- it does not certify that the AI agents governed by the platform are compliant.
Our enforcement ladder approach generates compliance evidence at the source. When an L5 hook prevents a context violation, that prevention is logged with the constraint it enforced, the file it protected, and the timestamp. This evidence maps directly to NIST AI RMF control families and EU AI Act requirements. The compliance artifact is the enforcement itself, not a separate certification layer.
For organizations that need to demonstrate AI governance to auditors, the question is whether you want evidence that your detection platform is secure (FedRAMP) or evidence that your AI agents are governed (enforcement ladder). Both matter, but they solve different problems. See our mapping to the NIST framework in How the Enforcement Ladder Maps to NIST AI RMF.
Agent Identity vs Agent Constraints: Two Models of Control
Zenity's agent-as-identity model treats governance as an access control problem. Each agent gets an identity, permissions are scoped, behavior is monitored against baselines. This is familiar to enterprise security teams because it extends existing IAM infrastructure. Their CTO demonstrated this approach at RSA Conference 2026 (Booth S-1849, March 23) showing real-time agent monitoring and policy enforcement.
Our model treats governance as an engineering problem. Agents do not need runtime identity tracking if their constraints are structurally enforced. A pre-commit hook that prevents secret exposure does not need to know which agent wrote the code -- it prevents the violation regardless. A test that validates context window integrity does not need agent identity to be effective.
The practical difference: Zenity requires ongoing operational overhead to maintain agent identities, update detection baselines, and respond to alerts. Structural enforcement requires upfront investment in constraint design but minimal ongoing operational cost. For teams with limited security operations capacity, this distinction drives total cost of ownership.
When to Choose Each Approach
Choose Zenity when your primary concern is monitoring existing production agents in real-time, you have a mature security operations team to handle detection alerts, you need FedRAMP authorization for federal contracts, or your agents interact with Microsoft ecosystem services where Entra ID integration adds value.
Choose Walseth AI when you want to prevent violations before they reach production, your team is building new AI agent systems and can embed governance from the start, you need compliance evidence that traces directly to enforcement actions, or you want governance costs that scale with constraints rather than threats.
Many organizations will eventually need both detection and prevention. The question is which layer to build first. We believe structural prevention should be the foundation, with runtime detection as a supplementary safety net.
