What we catch
Injecto maintains a signature library of real-world prompt injection techniques. Here's what gets blocked:
🔀
Instruction Override
Attempts to replace your system instructions with attacker-controlled directives. Classic "ignore previous instructions" attacks.
instruction-override
🎭
Role Hijacking
"Pretend you are..." or "you are now..." attacks that try to reassign your model's identity and behavior.
role-hijacking
🔓
Jailbreak Attempts
DAN prompts, developer mode exploits, and other techniques designed to strip model safety constraints.
jailbreak
📤
Prompt Leaking
Data exfiltration attacks that instruct your model to reveal system prompts, API keys, or internal configuration.
data-exfiltration
👤
Persona Injection
Gradual identity substitution through "new persona" commands designed to shift model behavior over a conversation.
persona-injection
⬆️
Privilege Escalation
"Act as system" and similar commands that attempt to elevate attacker permissions within your AI application.
privilege-escalation

Detection is rule-based with deterministic pattern matching — not an LLM, which means no latency overhead and no false positives from prompt context. Novel obfuscation variants are added to the signature library on a rolling basis.

"We integrated Injecto in an afternoon. It caught a DAN-variant attack on day one that our existing filters completely missed."

★★★★★
"The /demo/detect endpoint let me test against our real prompt corpus before committing. Exactly what I needed to convince my team."

★★★★★
"Three lines of Python. That's all it took. Blocks the stuff I was already losing sleep over — prompt leaking and role hijacking especially."

// HOW IT WORKS
One call. Full protection.
Drop Injecto in front of your LLM. Every prompt gets screened before it reaches your model.
STEP 01 — SEND
Forward user input
Before passing any message to your LLM, POST it to Injecto with your API key. Takes one line of code.
STEP 02 — SCAN
Pattern match in <5ms
Injecto runs deterministic pattern matching against 20+ attack signatures — no LLM in the loop, no latency surprise.
STEP 03 — DECIDE
Allow or block
Get a clean JSON verdict with risk score, severity, and attack type. Block, log, or flag — you stay in control.
// INTEGRATION
Works with any stack
Three lines of code. A clean JSON response. That's the whole integration.

Quick start 
import requests

# Screen every user message before your LLM call
result = requests.post(
    "https://injecto.xyz/api/detect",
    headers={"x-api-key": "inj_your_key_here"},
    json={"prompt": user_message}
).json()

if not result["safe"]:
    raise ValueError(f"Blocked: {result['attack_types']}")

# Safe — proceed to your LLM
