Many old or obsolete PCN switches, routers, and firewalls do not meet today's cyber security standards. As a result, this equipment presents a considerable vulnerability to the security of the network and process operations. Additionally, out of support equipment is often not repairable and raises the potential of longer downtimes in the event of a failure. This older equipment needs to be replaced with new hardware, current software, and updated configurations to support today's security measures. This is where Network Security gets to work. It improves PCN performance and security by replacing older and obsolete network equipment that is extremely vulnerable to cyber security attacks.
