Barracuda Networks, which provides easy-to-use security, spam-filtering and storage systems, filed on Tuesday with the SEC to raise up to $100 million in an initial public offering. The Campbell, CA-based company, which was founded in 2003 and booked $218 million in sales for the 12 months ended August 31, 2013, plans to list under the symbol CUDA but has yet to announce an exchange. Barracuda Networks initially filed confidentially on July 29, 2013. Morgan Stanley, J.P. Morgan and BofA Merrill Lynch are the joint bookrunners on the deal. No pricing terms were disclosed.
