For a software company, the app and the API are not a channel to the business, they are the business. That is exactly where the attacks land, and exactly where your enterprise buyers now demand proof before they sign.
The threat
Your real API surface is bigger than your team thinks, and it is the fastest-growing attack vector on the internet:
- Zero-days and framework exploits that land before you can patch across a dozen integrations.
- API abuse and broken object-level authorization (BOLA), the cross-tenant access a generic scanner never catches.
- Account takeover and credential stuffing against your login.
- AI-feature abuse, where a prompt injection changes behavior, not just words.
Meanwhile every enterprise deal now stalls on a security questionnaire and a SOC 2 review, and a pen-test report you have to produce on demand.
What Nemesis does
Nemesis is strongest exactly where a software company needs it: the application and API layer.
- Application Shield learns each service's normal request shapes, per tenant, and blocks the deviations, so a brand-new exploit or a cross-tenant access attempt is stopped by default-deny, no rewrite and no re-architecting.
- API Security discovers your real API surface and holds the authorization boundary a scanner misses.
- Red gives you the autonomous pen-testing and proof that closes the enterprise deal, findings that are verified, not just flagged.
It installs with a line of middleware and runs observe-only first, so it fits the way you already ship.
Why it's different
A signature WAF matches yesterday's attacks and does not understand your app. Nemesis learns your app's own behavior and blocks tomorrow's, and it proves your posture rather than just detecting, which is what an enterprise buyer's security team actually wants to see.
Getting started
Start free on one app or API, observe-only, in an afternoon. See your real surface and what is hitting it before you enforce a thing.
