According to the 2021 Devo SOC Performance ReportTM — which is based on the results of a survey of more than 1,000 security practitioners — having an understaffed SOC or constant turnover of security talent can cripple an organization’s security posture. Let’s look at some of the root causes that can lead to these two interconnected problems.

Good security may come from strong defenses, but strong security comes from a good offense. This is especially true for network security, where minutes can make the difference between a breach and a near miss.

Working in a Security Operations Center (SOC) is like working in an emergency room on a weekend shift at 2 AM. The steady stream of new alerts screaming for attention and combined with the lack of enough trained personnel make it a miracle that it all seems to work through on a string and a prayer. The question is though, when will the luck run out?
