Agent Security Tools Compared: PrivScan vs AgentRedTeam vs PyRIT vs Garak

If you are shipping agents, you need a way to test them before they touch production data. Here is how four tools line up. All four are real; pick by where you are in the lifecycle.

Tool	Vendor	Type	Primary focus	License
PrivScan	LX AI	Commercial SaaS	Pre-deploy guardrails: prompt/tool risk rating, input-output filters, EU AI Act mapping	Proprietary (subscription)
AgentRedTeam	LX AI	Commercial SaaS	Adversarial red-team / attack simulation against your agent	Proprietary (subscription)
PyRIT	Microsoft	Open source (Python)	Risk identification and red-teaming orchestration for generative AI	MIT
Garak	NVIDIA	Open source	LLM vulnerability scanning across known probe categories	Apache-2.0

How to choose

• Building guardrails now - start with PrivScan for a fast prompt/tool risk read and a cited report.
• Attacking your own agent - AgentRedTeam or PyRIT run adversarial scenarios you define.
• Scanning a model endpoint - Garak probes a hosted model across vulnerability categories.
• Open-source only - PyRIT (MIT) and Garak (Apache-2.0) are both permissively licensed.

None of these tools give legal advice. The EU AI Act and OWASP mappings are decision-support - confirm obligations against EUR-Lex and your qualified assessor.
