TrianSec API Security SDK

TrianSec SDK

TrianSec SDK is a lightweight Python SDK for integrating the TrianSec API Security Platform into your FastAPI/Starlette applications. It provides behavior-driven API protection without modifying your existing business logic.

---

✨ Features

• 🔒 Behavior-Driven Protection - Analyzes request patterns, not just rate limits
• ⚡ Fast Decision Path - Sub-15ms latency for security decisions
• 🛡️ Adaptive Policy Engine - Dynamically applies ALLOW, BLOCK, or THROTTLE decisions
• 🧠 Stateful Intelligence - Maintains historical behavioral state per identity
• 📊 Explainable Decisions - Every decision includes a human-readable reason
• 🔌 Plug-and-Play - Minimal integration with just one line of code
• 🎯 Multi-Tenant Isolation - Each client's security posture is independent

📦 Installation

pip install triansec

For FastAPI support (optional):

pip install triansec[fastapi]

For development:

pip install triansec[dev]

---

🚀 Quick Start

1. Get Your API Key

Sign up at TrianSec and generate your API key from the dashboard.

2. Add the Middleware

from fastapi import FastAPI
from triansec import TriAnSec

app = FastAPI()

# Add security middleware
app.add_middleware(
    TriAnSec,
    api_key="ts_live_xxxxxxxxx",
    timeout=5,
    fallback_action="allow",
)

@app.get("/")
async def root():
    return {"message": "Protected by TrianSec"}

---

📋 Usage Examples

Option 1: Direct Middleware (Simplest)

from fastapi import FastAPI
from triansec import TriAnSec

app = FastAPI()

app.add_middleware(
    TriAnSec,
    api_key="ts_live_xxxxxxxxx",
    timeout=10,
    fallback_action="allow",
)

Option 2: Class-based with Install

from fastapi import FastAPI
from triansec.security import TriAnSec

app = FastAPI()

security = TriAnSec(
    api_key="ts_live_xxxxxxxxx",
    timeout=10,
    fallback_action="allow",
)

security.install(app)

Option 3: One-Line Setup

from fastapi import FastAPI
from triansec.security import setup_security

app = FastAPI()

security = setup_security(
    app,
    api_key="ts_live_xxxxxxxxx",
    timeout=10,
    fallback_action="allow",
    add_health=True,
    add_shutdown=True,
)

With Configuration Object

from fastapi import FastAPI
from triansec import TriAnSec, SecurityConfig

app = FastAPI()

config = SecurityConfig(
    api_key="ts_live_xxxxxxxxx",
    timeout=10,
    fallback_action="block",
    enable_cache=True,
    cache_ttl=600,
)

app.add_middleware(TriAnSec, config=config)

🛡️ Security Decisions

Decision	Description
ALLOW	Request is legitimate, pass through to your application
THROTTLE	Request is suspicious, pass through with throttle headers
BLOCK	Request is malicious, return 429 Too Many Requests
