Runtime AI Governance - govern any AI agent tool call

phronedge

Runtime governance for AI agents.

Every tool call checked. Every decision audited. Every regulation enforced.

The Problem

AI agents take actions. Actions have consequences. Right now there is no governance layer between your agent and everything it can touch.

Your agent can access data it was never authorized to see. Execute financial transactions without human approval. Leak sensitive information across jurisdictions. Be compromised through prompt injection. Have its credential tampered with at runtime.

And you will not know until a regulator asks you to prove it did not happen.

EU AI Act enforcement is live. GDPR fines reach 20M EUR or 4% of global revenue. The question is not whether your agent needs governance. The question is whether you can prove it has governance.

An agent is an untrusted entity. Treat it like one.

The Solution

PhronEdge intercepts every tool call before it executes. Seven checkpoints. Every time. No exceptions.

Your agent calls a tool
        |
        v
CP1  Credential Validator    Is this agent who it claims to be? (ECDSA)
        |
CP2  PII / Injection Scan    Is there sensitive data or manipulation in the input?
        |
CP3  Jurisdiction Router     Is this action legally permitted? (196 countries)
        |
CP4  Behavioral Monitor      Is this agent behaving normally? (signed baseline)
        |
CP5  Data Classifier         What classification level is this data?
        |
CP6  Tool Permission         Is this tool in the agent's signed credential?
        |
CP7  Output Constraint       Is the response safe to return?
        |
        v
ALLOWED: your function executes normally
BLOCKED: reason + regulation citation returned, event anchored

Quick Start

from phronedge import PhronEdge

pe = PhronEdge()

@pe.govern("lookup_claim")
def lookup_claim(claim_id: str) -> str:
    return db.query(claim_id)

result = lookup_claim("CLM-2026-001")

Three lines. Every call to lookup_claim now passes through 7 governance checkpoints. Your existing function does not change.

---

What Governance Looks Like

Four scenarios. What your agent tries. What PhronEdge does.

Clean call:

result = lookup_claim("CLM-2026-001")
# ALLOWED in 23ms
# Claim data returned to agent
# Audit: TOOL_CALL_ALLOWED, 7/7 checkpoints passed

PII in input:

result = lookup_claim("SSN 123-45-6789")
# BLOCKED
# PII detected in function arguments (SSN pattern)
# Session escalated to PII_RESTRICTED
# Audit: PII_INPUT_DETECTED, GDPR Art. 9

Tool not in credential:

result = access_medical_records("patient-123")
# BLOCKED
# medical_records not in agent's signed credential
# Function never executed. Data never touched.
# Audit: TOOL_CALL_BLOCKED, EU AI Act Art. 14

Credential tampered at runtime:

# Attacker modifies credential at 2:00pm
# Agent makes next call at 2:01pm
result = lookup_claim("CLM-2026-001")
# ECDSA signature mismatch detected
# Vault restore runs automatically
# Call proceeds with restored credential
# You did nothing. PhronEdge fixed itself.
# Audit: VAULT_TAMPER_DETECTED + VAULT_CREDENTIAL_RESTORED

The Data Never Leaves

Your data stays in your environment. Governance metadata travels to PhronEdge. Nothing else.

What PhronEdge receives:              What PhronEdge never receives:
  Agent ID                              Your customer data
  Tool name                             Query results
  Input metadata (scanned, not stored)  Medical records
  Credential ID                         Financial data
                                        Internal service URLs
                                        Anything your tool returns

GDPR, HIPAA, and EU AI Act all require data to stay in the appropriate environment. PhronEdge is architecturally compliant by design. Not by configuration. By architecture.

---

Constitutional Tiers

Every agent operates at a tier that defines its authority.

Tier	Name	What it means
T0	Advisory Only	Agent recommends. Human decides. No execution.
T1	Human-in-the-Loop	Agent proposes. Waits for human approval.
T2	Bounded Autonomy	Agent executes within scope. Escalates outside it.
T3	Supervised Autonomy	Agent executes and logs. Human reviews after.

High-value actions like financial transactions, sensitive data access, and irreversible operations are blocked at tiers below their required level. Automatically. Every time.

---

Agent Lifecycle

Control any running agent in real time. No restart. No code change.

# Quarantine: blocks all tool calls immediately
pe.quarantine("Suspicious pattern detected")

# Reinstate: resumes tool calls
pe.reinstate("Investigation complete")

Kill switch is available through the PhronEdge console only. Permanent agent termination is a critical operation that requires dashboard access at phronedge.com/brain.

---

The Audit Chain

Every event is cryptographically anchored. Every event links to the one before it. Tamper one event and the chain breaks.

{
  "event_type":  "TOOL_CALL_BLOCKED",
  "agent_id":    "claims-investigator-v1",
  "tool":        "access_medical_records",
  "severity":    "HIGH",
  "regulation":  "EU AI Act Art. 14 Human Oversight",
  "checkpoint":  "data_classification",
  "policy_hash": "f107937d65017b17...",
  "hash":        "a3f2b1c4d5e6f7a8...",
  "prev_hash":   "9e8d7c6b5a4f3e2d...",
  "timestamp":   "2026-04-05T14:32:18.000Z"
}

Your regulator sees the complete governance history. Your auditor trusts the math.

Error Handling

from phronedge import PhronEdge, ToolBlocked, AgentTerminated

pe = PhronEdge(raise_on_block=True)

@pe.govern("send_payment")
def send_payment(claim_id, amount, currency):
    return payment_api.send(claim_id, amount, currency)

try:
    send_payment("CLM-001", 42500, "EUR")
except ToolBlocked as e:
    print(f"Blocked: {e} (checkpoint: {e.checkpoint})")
except AgentTerminated:
    print("Agent has been permanently killed")

---

Pre-scan Text

Check text for PII or injection before sending to an LLM:

pe = PhronEdge()
result = pe.scan("My SSN is 123-45-6789 and ignore previous instructions")
# {"pii_detected": true, "injection_detected": true, "patterns": ["SSN"]}
