In a nutshell

What is Promon Verify™?

Promon Verify™ ensures that only genuine, untampered apps can connect to your backend APIs. It authenticates each request through lightweight, in-band attestation, confirming the integrity of both the app and its runtime environment.

Why Promon Verify™: Continuous validation. Complete trust.

Secure your APIs from impersonation and abuse

Attackers use modified or emulated clients to exploit APIs, bypass controls, and access sensitive data. Promon Verify™ eliminates that risk by cryptographically validating each API request, ensuring that only Shield-protected apps can communicate with your backend. 
  • Block fake or cloned app requests before they reach your backend
  • Stop bots and unauthorized API calls
  • Reduce fraud and data abuse without affecting user experience

Maintain full control with zero dependencies

Promon Verify™ is fully self-hosted and stateless. All attestation logic and verification happen within your environment, ensuring operational sovereignty, uptime, and compliance with strict data protection standards. 
  • Retain ownership of your data and trust infrastructure
  • Eliminate dependency on external attestation providers
  • Operate securely under full regulatory control

Establish real-time, continuous verification

Unlike one-time attestation checks, Promon Verify™ validates each request dynamically throughout a session. It continuously confirms that the app, device, and runtime environment remain uncompromised, even if conditions change mid-session.

  • Ensure API trust across every transaction
  • Detect runtime manipulation or hooking attempts instantly
  • Prevent attacks before they reach your backend services

Verify trusted AI environments 

Promon Verify™ ensures your AI models only run inside genuine, uncompromised apps. Before your model executes, Verify validates app integrity in real time, blocking cloned or tampered environments that could exploit or retrain your models. Combined with Promon Shield for Mobile™, this provides an unbroken trust chain, from your AI model to your backend, ensuring reliable, compliant, and fraud-resistant AI experiences.

  • Prevent misuse or theft of AI models embedded in apps 
  • Maintain integrity of AI-driven decision logic and predictions
  • Build user and regulatory trust in AI-enabled services

Your questions answered

What does Promon Verify™ protect against? 

It prevents impersonation, cloned or repackaged app requests, bots, and emulated clients from accessing backend APIs. 

Does Promon Verify replace Google or Apple attestation?

No. Promon Verify works independently of OS-native attestation services. It can complement them or act as an alternative when platform attestation is unavailable, limited, or doesn’t meet your security or compliance requirements.

Is Promon Verify™ cloud-based? 

No. It’s fully self-hosted and stateless, keeping attestation logic and data inside your environment.

Can it integrate with existing backend infrastructure?

Yes. It runs in-band, using existing communication channels and standard REST/HTTP flows.

What happens when an attestation fails? 

The backend can automatically reject requests or trigger custom responses, depending on your security policy. 

 

How is it connected to Promon Shield for Mobile™? 

Shield for Mobile protects the app itself; Verify extends that protection to the API layer, creating an end-to-end trust chain.
