The approach you need to take to minimize the impact of network outages is twofold. The first step is 24/7 network monitoring that not only looks out for current failures but proactively identifies specific devices or nodes that are at risk of failure in the near future. Second is the need to automate alerts regarding high CPU and bandwidth utilization as well as malicious activity across the network to prevent downtime and costly breaches. As with the security team, it may be prudent to outsource these tasks to save both money and time. https://www.extnoc.com/mac-support/
