The one-line alternative to Wallarm
Wallarm is a modern API-security platform. Nemesis overlaps on API protection and goes wider: one positive-security baseline across your app, API and LLM, added with a single line and free to start.
Two different models
Wallarm is an API-security platform that combines rules with machine learning for API threat detection, aimed at security teams at API-first companies.
Nemesis Shield is a positive-security platform that spans the whole request path. A one-line, open-source SDK (Sentinel) learns each app, API and LLM's own normal behavior per tenant and blocks the deviations a signature ruleset never sees: IDOR/BOLA, broken auth, business-logic abuse and zero-days. Nemesis Edge adds a per-tenant protective-DNS and optional inline-proxy layer at the network edge, running in front of or on top of your existing CDN, and it all correlates into one view. Free tier, observe-first, about two minutes to protect an app.
Side by side
| Wallarm | Nemesis Shield | |
|---|---|---|
| Primary scope | API security | App, API, LLM, network and cloud, one correlated platform |
| Delivery | Platform deployment for security teams | One-line SDK a developer adds, self-serve |
| Model | Rules plus ML for API threats | Per-tenant positive-security baseline, learn then enforce |
| Start | Evaluation and deployment | Free tier, protect an app in about two minutes |
When to choose which
If your need is specifically an API-security platform run by a security team, Wallarm is built for that.
If you want one positive-security layer across app, API and LLM that a developer adds in a line and starts free, that is Nemesis Shield.
Questions
Is Nemesis Shield a Wallarm alternative?
Yes, and often a complement. Wallarm and Nemesis Shield solve overlapping but different problems: Wallarm works at the level it was designed for, and Nemesis adds a positive-security layer that learns your app's own per-tenant behavior and blocks the logic-level attacks (IDOR/BOLA, broken auth, business-logic abuse) that a signature ruleset is not built to see.
Can I run Nemesis Shield together with Wallarm?
Yes. Nemesis is a one-line SDK inside your app (and an optional edge layer), so it runs happily behind or on top of Wallarm. Many teams keep Wallarm for what it is good at and add Nemesis for the application-logic layer.
What does Nemesis catch that a signature WAF does not?
Attacks that are well-formed. A request for an object that is not yours (IDOR/BOLA), a broken-auth flow, or business-logic abuse has no bad pattern to match, so a signature engine passes it. Nemesis flags it because it deviates from the app's learned normal, per tenant.
