Buyer context
LLM / AI Application Security vs Alternative Categories
Where prompt-injection defence overlaps with EDR, MDR, XDR, SIEM, WAF, API security, and where it is genuinely additive.
Additive
Not a replacement for any
Inline
Sits in the LLM request path
SIEM
Closest integration point
WAF
Closest historical analogue
Coverage overlap
- EDR / MDR / XDR: cover endpoints and detection, do not see LLM payloads.
- SIEM: receives guardrail logs but does not filter prompts itself.
- WAF: blocks HTTP-layer attacks; agnostic to LLM intent.
- API security: protects API contracts; does not parse natural language.
- Prompt-injection guardrail: sits between user and LLM, the only layer that reads the prompt.
