Tenable Holdings Inc. plans to launch an initial public offering, according to a Securities and Exchange Commission filing late Friday. The Columbia, Maryland-based cybersecurity company said it plans to raise up to $100 million, but that amount is often used as a placeholder and is subject to revision. The company plans to trade under the ticker "TENB" on the Nasdaq. Morgan Stanley, J.P. Morgan, and Deutsche Bank Securities are listed among the underwriters. The company reported 2017 revenue of $187.7 million for a $41.8 million loss.
