Technical Breakdown
| Feature | Galileo | SupraWall |
|---|---|---|
| Real-time Action Blocking | Galileo observes and reports; SupraWall intercepts and blocks. | |
| Policy Engine (ALLOW/DENY) | Galileo has no enforcement policies, only evaluation metrics. | |
| Human-in-the-Loop Approvals | SupraWall pauses execution pending human review. | |
| Agent Vault / Secrets | Galileo doesn't manage credentials. | |
| EU AI Act Compliance Exports | SupraWall generates Article 12 tamper-proof reports. | |
| Observability / Tracing | Deep traces | Action-level Galileo wins on debugging depth; SupraWall wins on security depth. |
| Open Source | Galileo is Apache 2.0; SupraWall is commercial. | |
| Use Case | Eval & Debugging | Security Governance Complementary tools, not direct competitors. |
Observability is not enforcement
Galileo is excellent at what it does: tracing agent decisions, surfacing evaluation metrics, and helping teams understand why an agent behaved unexpectedly. But observability tools are forensic by nature — they analyze the past. SupraWall's Agent Runtime Security (ARS) framework intercepts every tool call before execution, applying ALLOW/DENY policy rules in real-time so harmful actions never reach the environment in the first place.
The Verdict
Use Galileo for deep behavioral tracing and post-hoc evaluation of agent runs. Choose SupraWall when you need real-time enforcement, a built-in secret vault, human-in-the-loop approvals, and EU AI Act Article 12 compliance exports. The two tools are complementary — but only one can stop a rogue agent before it deletes production data.
Galileo Approach
Observability is forensic. By the time Galileo flags a problem, the tool call has already executed.
SupraWall Approach
Enforcement happens before the action. No damage. No post-mortem. Just prevention.
Key Differences
When does it act?
After execution — identifies what went wrong
Before execution — prevents it from happening
Primary purpose
Developer tooling and debugging
Security and compliance governance
Policy engine
No policy engine — evaluation metrics only
Full ALLOW / DENY / REQUIRE_APPROVAL engine
Credentials & secrets
No vault or secret management
Built-in vault with per-agent secret injection
Frequently Asked Questions
How is SupraWall different from Galileo?
Galileo is an observability platform for debugging agent behavior. SupraWall is a runtime security firewall that prevents unauthorized actions before they happen. They serve complementary purposes.
Can I use SupraWall and Galileo together?
Yes. Use Galileo for evaluation and behavioral tracing; use SupraWall for enforcement, policy control, and EU AI Act compliance.
Does Galileo block tool calls?
No. Galileo monitors and evaluates agent actions but does not intercept or block them. If you need enforcement, you need SupraWall.
