Cons

Lakera - Pros & Cons
Pros
- ✓Detection models trained on the largest public adversarial dataset (Gandalf, 60M+)
- ✓Latency genuinely fast enough for synchronous inline use, not just async logging
- ✓Both prompt and response screening in one API — covers the full I/O surface
- ✓SOC 2 Type II + EU origin makes compliance conversations easier
- ✓Open PINT benchmark gives credibility versus closed-evaluation competitors
Cons
- ✗Pricing opacity makes early-stage budgeting hard — must talk to sales
- ✗Free tier is small (1K req/month) — production prototypes hit limits fast
- ✗Adds a network hop and per-call cost on top of the LLM bill
- ✗Custom policies still require some prompt-engineering expertise to author
- ✗No general-purpose content moderation beyond the LLM-security focus
