AI Agent Security

Your agents are
in production.
Who's watching?

Vigil is the autonomous security layer for AI agents — monitoring behavior 24/7, catching prompt injection and unauthorized tool calls before they become breaches.

$40B+ AI security market by 2030
89% rise in AI-enabled attacks (2026)
<1% of agents have runtime security
AGENT ACTIVITY — LIVE SECURED
agent-07 PERMITTED send_email(to=support@acme.com) 0.04s
agent-12 FLAGGED read_file(path=/etc/passwd) 0.31s
agent-03 BLOCKED inject: ignore previous instructions 0.01s
agent-19 PERMITTED call_api(provider=stripe, action=charge) 0.87s
agent-22 PERMITTED write_record(db=customers, data=*) 0.12s

Agents ship. Security doesn't.

Every week, engineering teams deploy AI agents that access production systems, customer data, and financial APIs. Almost none of them have runtime security monitoring. The agents go live — and then it's just trust.

Prompt injection attacks bypass authorization, exfiltrate data, and hijack agent behavior — with no detection layer.

Agents inherit broad credentials from engineers — no least-privilege enforcement at runtime.

No behavioral baseline. You can't detect anomalous actions because you don't know what normal looks like.

Compliance auditors are starting to ask about AI agent governance. Most teams have no answer.

The security employee that never sleeps.

01

Prompt Injection Detection

Every inbound instruction is analyzed before it reaches your agent. Manipulated prompts, jailbreak attempts, and context poisoning are caught at the gate.

02

Behavioral Baseline & Anomaly Detection

Vigil learns what your agents normally do — then flags deviations in real time. Out-of-scope API calls, unusual data access patterns, and unexpected tool chains trigger instant alerts.

03

Tool Call Enforcement

Define what your agents can and cannot do. Vigil enforces policy at runtime — blocking unauthorized calls, rate-limiting sensitive tools, and logging every decision for audit.

04

Daily Incident Digest

Every morning you get a plain-English briefing: what happened, what was blocked, what requires your attention. No noise — just signal.

Threats we catch today

09 JUN 2026
HIGH
Prompt injection via role-play bypass — An agent's instruction set was overridden using a simulated "developer mode" prompt embedded in user input. Vigil caught the attack vector and blocked the escalated action.
08 JUN 2026
MED
Unauthorized database read from agent session — An agent with email-sending permissions attempted to read from the HR database. Policy violation blocked and logged.
07 JUN 2026
MED
Credential exfiltration attempt via tool chain — A multi-step chain of tool calls attempted to extract API keys from environment variables. Behavioral anomaly score triggered alert before data left the session.
05 JUN 2026
HIGH
Context poisoning in RAG pipeline — Retrieved context was silently manipulated by an adversarial document inserted into the knowledge base. Detection scored the injected context as anomalous before generation completed.
