# Hawcx vs Silverfort for AI agent authentication

> Hawcx vs Silverfort: both check AI agent tool calls at runtime. Hawcx also proves who delegated each action and gives every call a one-time grant.

Both link AI agents to the people behind them and check each tool call before it runs. Hawcx also starts each agent at a person’s phishing-resistant sign-in, carries proof of who delegated every action, and gives every tool call a grant that works once.

## Hawcx vs Silverfort, side by side

Nine capabilities: the six most vendors now cover, and the three that carry a person’s authority to each action.

| From the person to the action |   |   |
| Phishing-resistant human root of trust: The agent’s authority starts with a person’s phishing-resistant sign-in. | Full | Partial |
| Proof of delegation on every action: Each action carries proof that a specific person delegated it. | Full | Not covered |
| A single-use grant for every tool call: A captured call can’t run twice. | Full | Not covered |

## Which one fits?

### Choose Hawcx when

Agents must hold no standing credentials, each tool call has to carry cryptographic proof of the person who delegated it, and a captured call should never run twice.

### Choose Silverfort when

Your priority is finding every AI agent across clouds, identity providers and SaaS, mapping each to an owner, and enforcing runtime policy on the same platform that protects your human and service accounts.
