Among competitors listed in the S-1 are IBM, Qualys, Rapid7, Tanium and CrowdStrike. The latter two are privately held companies that have racked up hundreds of millions in venture capital funding and are closely watched for IPO news. Other cybersecurity IPOs this year include Carbon Black and ZScaler.
