What Is AppSec and Why Is It Critical?

Application security (AppSec) refers to the different sets of processes, practices, and tools maintaining the security of software applications against any external threat or vulnerability. AppSec involves planning and development throughout the entire SDLC-from deploying to maintaining applications.

The rise of cloud computing and microservices architectures means that modern organizations are more data-centric than ever, making the cost of potenital data breaches that much higher. Having strong AppSec isn't just about protecting the company's software or avoiding fines for regulatory non-compliance—its how companies safeguard their reputations and customer trust.

Application security involves planning and development throughout the entire software development lifecycle (SDLC)—from deploying to maintaining applications. And the best way to ensure your applications are always secure is to ensure you’re always aware of your threat real-time security information and event management (SIEM).
