Why choose EvalGuard over Datadog LLM Observability
- 300+ attack plugins and 100+ red-team strategies with published counts — Datadog documents no offensive testing library
- Purpose-built for AI evaluation and security rather than an add-on to an APM suite
- Self-hostable on Docker/Helm with Apache 2.0 SDKs and CLI — the Datadog platform is SaaS-only
- Free tier — Datadog starts at $35/host/month
- Firewall latency published and reproducible at 3.67ms p95 (/trust/latency) — AI Guard publishes no comparable figure
Where Datadog LLM Observability leads
- Datadog has best-in-class infrastructure monitoring
- Datadog ships AI Guard, an inline runtime guardrail that inspects and blocks prompts and tool calls — this page previously said Datadog had no firewall, which was false
- Datadog has 27K+ enterprise customers
- Datadog has deeper APM and log management
