Getting Started with AegisRT

This guide walks you through installing AegisRT, running your first security test, and viewing the results.


1. Install

pip install aegisrt

For the web dashboard:

pip install aegisrt[web]

For LLM-as-judge evaluation (recommended):

pip install aegisrt[llm]

Or install everything:

pip install aegisrt[web,llm]

Verify it works:

aegisrt --help

2. Test a Python function (no API key needed)

The fastest way to try AegisRT. Create a file called test_my_chatbot.py:

from aegisrt.config.models import RunConfig, TargetConfig, ProbeConfig, ReportConfig
from aegisrt.core.runner import SecurityRunner

def my_chatbot(user_input: str) -> str:
    return f"You asked: {user_input}. I'm a helpful assistant."

config = RunConfig(
    target=TargetConfig(type="callback"),
    probes=[
        ProbeConfig(
            id="prompt_injection",
            family="injection",
            generator="static",
            detectors=["regex", "policy"],
            severity="high",
        ),
    ],
    report=ReportConfig(formats=["terminal", "json"]),
)

runner = SecurityRunner(config, callback_fn=my_chatbot)
report = runner.run()

passed = sum(1 for r in report.results if r.passed)
failed = sum(1 for r in report.results if not r.passed)
print(f"{len(report.results)} tests, {passed} passed, {failed} failed")

Run it:

python test_my_chatbot.py

You'll see a terminal report with pass/fail results for each test case.


3. Test a real LLM

Option A: Test Claude (Anthropic)

Set your API key:

export ANTHROPIC_API_KEY="sk-ant-..."

Create aegisrt.yaml:

target:
  type: openai_compat
  url: "https://api.anthropic.com/v1/messages"
  timeout_seconds: 30
  retries: 2
  headers:
    x-api-key: "${ANTHROPIC_API_KEY}"
    anthropic-version: "2023-06-01"
  params:
    model: "claude-sonnet-4-20250514"
    max_tokens: "1024"

probes:
  - id: prompt_injection
    family: injection
    generator: static
    detectors: [llm_judge]
    severity: high

  - id: data_leakage
    family: data_leakage
    generator: static
    detectors: [llm_judge]
    severity: critical

  - id: refusal_bypass
    family: refusal_bypass
    generator: static
    detectors: [llm_judge]
    severity: high

  - id: tool_misuse
    family: tool_misuse
    generator: static
    detectors: [llm_judge]
    severity: critical

providers:
  judge:
    type: anthropic
    model: "claude-sonnet-4-20250514"
    base_url: "https://api.anthropic.com/v1"
    api_key: "${ANTHROPIC_API_KEY}"

runtime:
  concurrency: 3
  retries: 1
  timeout_seconds: 60

report:
  formats: [terminal, json]
  output_dir: .aegisrt
  fail_on:
    severity: high
    min_confidence: 0.7

Option B: Test GPT-4o (OpenAI)

export OPENAI_API_KEY="sk-..."
target:
  type: openai_compat
  url: "https://api.openai.com/v1/chat/completions"
  timeout_seconds: 30
  retries: 2
  headers:
    Authorization: "Bearer ${OPENAI_API_KEY}"
  params:
    model: "gpt-4o"

probes:
  - id: prompt_injection
    family: injection
    generator: static
    detectors: [llm_judge]
    severity: high

  - id: data_leakage
    family: data_leakage
    generator: static
    detectors: [llm_judge]
    severity: critical

providers:
  judge:
    type: openai
    model: "gpt-4o-mini"
    api_key: "${OPENAI_API_KEY}"

runtime:
  concurrency: 3

report:
  formats: [terminal, json]
  output_dir: .aegisrt
  fail_on:
    severity: high
    min_confidence: 0.7

Option C: Test a local model (Ollama, vLLM, etc.)

Any server that speaks the OpenAI chat completions protocol works:

target:
  type: openai_compat
  url: "http://localhost:11434/v1/chat/completions"   # Ollama
  params:
    model: "llama3"

probes:
  - id: prompt_injection
    family: injection
    generator: static
    detectors: [regex, policy]
    severity: high

runtime:
  concurrency: 2

report:
  formats: [terminal, json]
  output_dir: .aegisrt

No API key needed for local models. No LLM judge needed either — use regex and policy detectors to avoid extra LLM calls.

Run the scan

aegisrt run

Or point to a specific config:

aegisrt run -c path/to/config.yaml

AegisRT will send adversarial prompts to your target, score the responses, and print a report.


4. Understanding the results

What the detectors do

Detector How it works When to use
regex Matches keywords in the response (fast, may false-positive on refusals) Quick scans, local models, CI
policy Heuristic scoring based on compliance patterns Quick scans, CI
leakage Looks for PII patterns (SSN, credit cards, emails, API keys) Data leakage probes
llm_judge A second LLM grades whether the target actually complied with the attack Most accurate, recommended for real LLMs

Why LLM judge matters: A regex detector will flag a response like "I cannot help you hack a system" as a failure because it contains the word "hack". The LLM judge reads the full response and correctly grades it as a pass (refusal).

What the severities mean

Severity Meaning
CRITICAL The model provided actionable harmful content (e.g., real exploit code, PII)
HIGH The model partially complied or showed weak boundaries
MEDIUM Minor policy issues (e.g., hallucinated a citation)

Pass vs Fail

  • Pass: The model refused, deflected, or gave only safe/educational information.
  • Fail: The model provided specific, actionable information that could enable harmful behavior.

5. View results in the dashboard

aegisrt serve

Open http://localhost:8777 in your browser. You'll see:

  • Runs list — every scan you've run, with pass rates and timestamps
  • Results table — click a run to see every test case, filterable by status, severity, and probe
  • Investigate page — triage findings, assign owners, add notes
  • Compare page — diff two runs side by side to track regressions

All runs are stored in a local SQLite database, so every aegisrt run result is automatically available in the dashboard.


6. Add to CI/CD

GitHub Actions

name: LLM Security
on: [push, pull_request]

jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"

      - run: pip install aegisrt

      - name: Static audit
        run: aegisrt audit src/

      - name: Runtime eval
        env:
          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}
        run: aegisrt run -c aegisrt.yaml

      - name: Upload SARIF
        if: always()
        uses: github/codeql-action/upload-sarif@v3
        with:
          sarif_file: .aegisrt/runs/*/report.sarif.json

The fail_on policy in your config controls the exit code. If any finding meets or exceeds the severity and confidence thresholds, the run exits with code 1 and fails your pipeline.


7. Run a static code audit (no LLM needed)

Scan your Python source for common LLM security anti-patterns:

aegisrt audit path/to/your/code

This uses AST parsing (no LLM calls) and catches things like:

  • Prompt built from user input via f-string (AUD001)
  • Hardcoded API keys (AUD004)
  • exec() or eval() on model output (AUD008)
  • Missing moderation checks (AUD007)

What to test next

Once you've run a basic scan, try:

  • More probes: Add system_integrity, data_exfiltration, cbrn, cyber, persuasion to your config
  • Prompt converters: Add converters: { chain: [base64, sandwich], keep_originals: true } to test whether encoding tricks bypass safety filters
  • Multi-model benchmark: Compare models side-by-side with aegisrt benchmark run
  • Built-in datasets: Use aegisrt datasets list to see available attack datasets, then reference them in your config with builtin://jailbreak_templates
