Broken authorisation
The key works, the caller shouldn't
A valid key in the wrong hands looks like normal traffic. Object-level authorisation flaws let one client read another customer's data.

| Why a call was flagged | Limit exceeded | Rule or score | Plain-English reason with the signals behind it |
| Where it's weaker | Can't tell a partner peak from an attack | Built for security teams, not compliance evidence | Narrower than a dedicated API security platform. Covers the flows that carry compliance and payment data |

It watches API calls for misuse: wrong or expired credentials, scripted abuse, scraping and authorisation flaws. Aria Linkwell focuses on the APIs that carry customer, screening and payment data, explains each flag and sends it to your security team by the rules you set.
Aria recommends. She can apply throttling rules your security team has approved only where you allow it. Medium and high risk go to a person. A kill switch turns Aria off without touching your gateway.
No. Aria is narrower. She covers the API flows your compliance and payment work depends on, and keeps the evidence in the same record as your other FluxForce agents. Most teams will keep their existing gateway and security tools.
Screening, monitoring and onboarding all run on data that moves through APIs. A misused API can expose customer data, interrupt screening or trigger an incident report under DORA or CERT-In directions. The compliance team needs that evidence as much as the security team does.
Aria reads your live API traffic metadata, flags and records, but no call is throttled. Your current controls keep working, and you compare her findings with your security team's. You decide whether, and where, to switch on any autonomy afterwards.
API gateway logs with client identity, credential, endpoint, timing, volume and response codes. Registered client scopes help her check each key. Request bodies are optional.
FluxForce runs as SaaS, on-premise or hybrid, built on Microsoft Azure. We agree data residency and which components run inside your environment during deployment design, before any data moves.
