Pros
Resume fodder abounds as there are no major global infrastructure projects completed. You will have a chance to build global infrastructure.
Cons
Power struggles are tearing this company apart. It is clear that the NTT Security is going to adhere to what Europe dictates at Tokyo's direction. If you are someone who takes initiative or needs details in order to implement a global technology, look elsewhere. This company is a 1990s, top down culture where you will be told what your solutions are and how you will implement them. Asking questions and taking the lead is punished. As a result, most back office staff is focused on reactive operations and has little knowledge or experience in actual engineering work. Rumors of outsourcing abound. Little to no usable communication.
