Preventing prompt injection in multi-tenant SaaS - runtime security patterns

Preventing prompt injection in multi-tenant SaaS - runtime security patterns targets a $4.8B = 160,000 target SaaS product teams x $30,000 ACV. Rationale: global pool of mid-market and enterprise SaaS vendors that would buy security/compliance tooling at $20k-50k ACV. total addressable market with medium saturation and a year-over-year growth rate of 35% adoption growth for LLM security tooling as more products add model features.

Key trends driving demand: LLM adoption in product features -- broadening attack surface as more SaaS UIs and APIs call LLMs, increasing demand for runtime protections; Developer-first security buying -- teams prefer SDKs and integrations that fit into CI and runtime rather than heavyweight consulting; Shift to runtime observability -- security moves from static controls to continuous monitoring and policy enforcement where models are used.
