Cisco has the FMC as a centralized tool, but sometimes they have too many dependencies. I faced a problem this weekend because while trying to solve an issue with one of the company's firewall management centers, I couldn't update or install an update on the platform due to a remote site being down. The device got stuck in my queue. I had to cancel my maintenance because of that. Everyone was expecting me to fix many bugs, but because of one device, I had to cancel everything. Sometimes the ID is nice around Cisco, but another area they need to improve is the capability to manage multiple devices. The FMC manages many devices, but if I put too many, around 300 devices, it becomes very slow, and the system becomes heavy.
