Lakera
the only commercial vendor here you can start using without talking to anyone.
genuinely lower friction than anything else commercial here — with the red-teaming service sold separately from the product you can actually sign up for.
lakera is the only paid vendor in this ranking with a confirmed free self-serve entry point. that alone distinguishes it in a category where every other commercial option routes you to a demo booking before you learn anything.
what it tests: direct and indirect prompt injection, ai data leakage, toxic content generation, and multilingual and multimodal attacks, with model-agnostic guardrails that sit in front of whatever you're running. it maintains a 1,000-plus member practitioner community and publishes guides including an agentic ai security playbook.

genuinely lower friction than anything else commercial here — with the red-teaming service sold separately from the product you can actually sign up for.
we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
