In addition, the Market Share and Market Forecast documents will be refreshed in 1Q21 to include the calendar year 2020 in the Cybersecurity Rollup 2021). IDC did not ask participating vendors for market revenue estimates for 2020, but many volunteered that their revenue was not only ahead of revised guidance but pacing with pre-COVID-19 guidance, many actually have revenue-breaking quarters.
