The concept of “end-to-end” security is a bit of a vague one. Depending on the lens one looks through, it could mean having security products from a single vendor that range from endpoints to the data center within the corporate environment. If you’re in a business that relies heavily on the cloud, this might not be sufficient and the security capabilities might need to extend into public clouds.
But is that enough?
The answer is, in actuality, probably not. Security encompasses a broad range of technologies, and no single vendor can deliver everything. Despite an effort to consolidate down the number of vendors, businesses must face the harsh reality that multi-vendor is the norm. The goal for security vendors should be to enable customers to use multiple vendors but maintain a single architecture.
