How to read it
Green is 80% or more, Amber 50% to 79%, Red below 50%. Areas follow the OWASP Top 10 for LLM Applications categories; fix the Red rows that give the model tool access first.

LLM security tools by risk category
There is no single “LLM firewall.” Securing an LLM app means covering each OWASP LLM risk with the matching class of tool. Here is how the PlayCISO LLM security tools line up:

FAQ
What are LLM security tools?
LLM security tools are software that finds and reduces the risks specific to large-language-model applications — prompt injection, sensitive-data disclosure, insecure output handling, excessive agency in tool-using agents, model/supply-chain issues, and abuse of the model. They range from prompt-injection scanners and guardrails to agent/MCP config auditors, model red-teaming suites, and AI bill-of-materials scanners, and they map to the OWASP Top 10 for LLM Applications.
What are the best free LLM security tools?
PlayCISO offers several browser-based ones: Prompt Scan (checks content for prompt-injection patterns), MCP Guard (audits an MCP/agent configuration), Model Audit (red-teams a model endpoint you control), AI Footprint (maps your AI attack surface) and AI BOM (inventories AI components). This page also gives an OWASP-LLM-Top-10 self-assessment to tell you which categories to prioritise.
How do LLM security tools map to the OWASP LLM Top 10?
Each OWASP LLM risk has a matching class of tool: prompt-injection scanners for LLM01/LLM05, guardrails and DLP for LLM02, AI-BOM and dependency scanners for LLM03/LLM04, agent/MCP auditors and human-approval gates for LLM06, and monitoring for LLM09/LLM10. The assessment on this page scores your app against each category so you know which tools to reach for first.
Do I need special tools to secure an LLM application?
You need both process and tooling. The highest-value control is treating tool and retrieved content as data, never instructions, plus least-privilege tool access and human approval for high-impact actions. Tools help you find where those controls are missing — but start by scoring your app so you invest in the right ones.
Are these LLM security tools free?
A free account gets 3 free tool runs, shared across every tool, including this assessment and the linked PlayCISO scanners (Prompt Scan, MCP Guard, Model Audit, AI Footprint, AI BOM); after that they need Pro, $5/month or $40/year.
