Your firewall passed, still attack happens?

To stop attacks, security teams trust their existing controls: WAFs, API gateways, and rate limiting.

That assumption is where the problem starts.

The most damaging API attacks today don’t look malicious. They are technically valid requests that follow the exact structure your systems expect. A refund is processed through the correct API. A loyalty redemption that passes every check. A transaction executed using legitimate credentials.

Nothing is “broken” from a protocol or signature perspective.

But the outcome is wrong, money lost, data exposed and workflows abused.

These are business logic attacks. And they are invisible to traditional security tools by design, because those tools evaluate requests in isolation, not in the context of how your business is supposed to operate.

This is why the gap is growing.

37%* of organizations already rank API security among their top challenges (*Gartner 2024 Market Guide for API Protection). Not because they lack tools but because their tools are solving the wrong problem.

The issue is not identifying malformed or malicious traffic.  It’s detecting when perfectly valid API activity is being used in unintended ways.

This is where AppSentinels changes the security approach.

Instead of only inspecting requests, AppSentinels maps how your APIs are actually used across workflows, users, and data flows. It identifies when behavior deviates from intended business logic, even if every request appears legitimate.

Because in modern API environments, the biggest threats are not the ones that look like attacks - they are the ones that don’t.

Finally, AI runs on APIs and there is no AI security without API security. AppSentinels brings a unique Business Logic Security approach to protect both Agentic AI and API-driven applications.
