Security Operations (SecOps): The Backbone of Modern Cyber Defense
In today’s digital landscape, cyber attacks are continuous, automated, and increasingly sophisticated. Organizations can no longer rely on periodic security checks or isolated tools. They need a continuous, structured, and operational approach to cybersecurity. This is known as Security Operations (SecOps). Security Operations forms the foundation of how organizations detect, investigate, and respond to cyber…
