2021 was a record year for the total number of 0-day vulnerabilities disclosed and exploited. Mandiant, which was purchased by Google in March, found 80 0-days exploited in the wild. This spike in potentially dangerous vulnerabilities is troubling news for Security Operations Center (SOC) teams that have to seek out ways to mitigate the initial risk and then remediate once a fix has been issued. There have been reports that criminal groups have been using more 0- days, buying them from black markets that sell them to highest bidder.
