Can DevSecOps prevent data breaches in cloud environments?

Can DevSecOps prevent data breaches in cloud environments, especially with the growing complexity of multi-cloud deployments? I’ve been exploring secure development practices and wonder how effective DevSecOps really is in identifying and mitigating threats before they escalate. Specifically, how does it perform in AWS environments? Are there tools or frameworks tailored to AWS security? Also, does pursuing an AWS DevSecOps Certification provide enough knowledge to implement these security measures effectively? I’d love to hear real-world examples or use cases where DevSecOps actually helped prevent breaches or minimized impact in cloud-native applications. Any insights or resources are appreciated!
