The talk that was presented at the APISecure 2022 conference, in which I discuss why I believe that 'API Security' is merely a small portion of the actual problem space, which is application security, and how you can leverage multi-layer protection using a single unified CNAPP platform to achieve smart defense in depth.

10. False sense of
security
Fail to secure all
application layers

Siloed & fragmented
security protections
APIs are a key element in every modern application. However, APIs are just
one element among many others.
If you only focus on securing APIs:
To realize the full potential of cloud native app sec,
API security must be a part of a holistic approach.
