Exogram vs HiddenLayer
“HiddenLayer detects threats within your AI models; Exogram prevents destructive actions at the execution layer.”
What HiddenLayer Does
- •HiddenLayer provides an AI security platform focused on detecting and responding to threats against machine learning models.
- •They cover the model lifecycle, identifying adversarial attacks, data poisoning, and model exfiltration attempts to protect model integrity.
- •Their focus is on model integrity and threat intelligence, but they lack deterministic, real-time governance over the *actions* an AI takes via tool calls.
What Exogram Does
- ▸Exogram establishes a 0.07ms deterministic execution boundary around all AI tool calls and external actions.
- ▸It precisely blocks destructive tool calls, prevents unauthorized data access, and enforces Zero Trust policies on AI-driven actions, regardless of model integrity.
- ▸Exogram provides the critical missing piece: a real-time, deterministic firewall that validates and governs every single action an AI attempts to take, ensuring operational safety and compliance.
Key Differences
| Dimension | HiddenLayer | Exogram |
|---|---|---|
| Primary Focus | AI Threat Detection & Model Integrity | Execution Governance |
| Security Method | Behavioral Analysis & Anomaly Detection (Probabilistic) | Deterministic Logic (0.07ms) |
| False Negative Rate | Probabilistic / Unknown | 0.00% |
The Verdict
Use HiddenLayer to gain visibility into threats against your AI models and protect their integrity from adversarial attacks. However, for real-time, ironclad security that prevents unauthorized or destructive actions *taken by* your AI, Exogram is indispensable. Exogram acts as the final, deterministic gatekeeper for all AI tool execution, ensuring Zero Trust at the action layer.

Frequently Asked Questions
Does Exogram replace HiddenLayer?
No, Exogram does not replace HiddenLayer. HiddenLayer focuses on securing the AI model itself from attacks and ensuring its integrity, while Exogram secures the *actions* the AI takes by governing tool execution.
Can I use Exogram along with HiddenLayer?
Absolutely. They are highly complementary. HiddenLayer can help ensure your models are robust and untampered, while Exogram ensures that even a robust model cannot execute unauthorized or harmful actions, providing a layered defense for your AI systems.
