A map of threat origins, from Trustwave’s free 2011 Global Security Report (WEB HOST INDUSTRY REVIEW) — Security compliance firm Trustwave Holdings ( www.trustwave.com ) announced late last week that it has filed its initial registration documents with the US Securities and Exchange Commission for an initial public offering in which the company hopes to raise up to $100 million through the sale of its stock. Trustwave is reportedly one of quite a few companies to file early IPO documents last week, part of a larger trend toward more new IPOs, after several years of inactivity and near-inactivity. Trustwave posted revenues of $111.5 million in 2010, with an overall loss of $4.6 million.
