Detect attacks on your APIs in real time. Monitor every LLM call your AI agents make. Protect your data before a breach does it for you.
ApiSentinel secures your API. AgentSentinel secures your AI. Use one or both — they are designed to work together.
Real-time API security monitoring. Detect BOLA, DDoS rate spikes, brute force, and shadow APIs before they cause damage.
AI agent security and governance. Monitor every LLM call for prompt injection, PII leaks, jailbreaks, and policy violations.
A 10-line agent snippet installs in any framework. Detection starts within 60 seconds. No security team required.
z-score comparison against a 30-day per-minute baseline per endpoint. Unknown attacking IPs caught automatically.
Detects when one authenticated user accesses 15+ distinct object IDs on the same endpoint in 120 seconds.
20+ failed authentication attempts from one IP address in 5 minutes on any login, token, or auth endpoint.
Any endpoint not in your approved whitelist that receives traffic. Fires once per 24h per endpoint to avoid noise.
Works with every framework
AgentSentinel intercepts every call, runs 8 security detectors in milliseconds, and blocks threats before the model responds — with zero internet required.
15 patterns covering instruction override, system prompt extraction, DAN attacks, and delimiter injection.
7 patterns. The only detector that blocks calls in real time before the LLM ever sees the request.
13 types: email, phone, SSN, credit cards, Aadhaar, IBAN, API keys, AWS keys, JWTs, date of birth.
Detects prompts requesting bulk data dumps, credential exports, and mass data extraction.
Every model call compared against an approved registry. Wildcard patterns. Unapproved models flagged.
Offline cost table for 14 major models. Per-agent statistical baseline. Fires when spend exceeds 5× normal.
Agents making 50+ calls per minute flagged as potential infinite loops before costs spiral.
8 default governance rules. Toggle individually. Change any from flag to block. Extendable for compliance.

"We had a BOLA attack running for 3 days before we discovered it through a customer complaint. ApiSentinel would have caught it in 60 seconds. The setup literally took 8 minutes."
"AgentSentinel caught a developer accidentally pasting customer SSNs into a GPT-4 prompt on day two. The PII detection is genuinely impressive. Zero configuration."
"The governance reports are exactly what our CISO needed. Monthly AI usage, cost tracking, policy violations — all in one document. And it runs completely offline."
ApiSentinel monitors traditional HTTP API traffic — it detects BOLA attacks, DDoS rate spikes, brute force login attempts, and undocumented shadow API endpoints. AgentSentinel monitors AI agent LLM calls — it detects prompt injection, PII leakage, jailbreak attempts, shadow model usage, and governance compliance. They solve different problems and work best together.
No. AgentSentinel works 100% on-premise with zero internet connectivity required. All 8 detectors run on local regex patterns and statistical baselines. Governance reports are generated using an offline template. No prompt content, response content, or personal data ever leaves your infrastructure.
ApiSentinel deploys to Railway in about 25 minutes following the deployment guide. The client agent installs in under 10 minutes using any of the provided SDK files (Node.js, Python Flask, FastAPI, PHP). AgentSentinel follows the same deployment process. From zero to live dashboard: approximately 30 minutes for each product.
Yes. ApiSentinel free tier covers 3 APIs with 7-day alert history and two detectors. AgentSentinel free tier covers 2 AI agents with 7-day history and basic detection. Both free tiers are permanent — no time limit, no credit card required. You can also explore both products using the live demo dashboards linked on this page.
AgentSentinel works with any LLM provider: OpenAI (GPT-4, GPT-3.5), Anthropic (Claude 3.5, Claude 3), Google (Gemini), Meta (Llama), Mistral, and any custom or on-premise model (Ollama, vLLM, LM Studio). Drop-in SDK wrappers are provided for OpenAI, Anthropic, and LangChain. Any other framework can use the generic HTTP reporter.
After completing your order you will receive an email from hello@alfasentinel.io within 60 seconds containing your license key, your API key, and links to the deployment guide and integration documentation. The entire onboarding process is self-serve — no setup calls or waiting periods.
Yes. Customers using both ApiSentinel and AgentSentinel can receive bundle pricing. Contact us at hello@alfasentinel.io or use the bundle pricing button in the pricing section above and we will respond within one business day with a custom quote.
