Security landscape has been steadily changing due to proliferation of cloud computing and online services coupled with increasingly mobile workforce. The traditional perimeter and segmentation-based approaches alone no longer match the needs of this new security landscape. With static, well-defined perimeters eroding, organizations need to implement dynamic security approaches that are flexible and continuous in nature. Identity is quickly becoming a new perimeter and frameworks and architectures such as Zero Trust and Secure Access Service Edge (SASE) are redefining how cybersecurity is tackled. But novel approaches don’t change the fundamentals. That's why I advocate for a time tested defense in-depth strategy that combines multiple and different methods of protection, both traditional and new, and infuses them with the cutting edge Machine Learning (ML) and Artificial Intelligence (AI) technologies that add behavioral dimension and automation to further enhance the practice
