Buy • Price 23.59 on Jan. 12 by Lazard Capital Markets The security-platform buildout continues with the [$21 million all-cash] Immunet acquisition…. Immunet's cloud-based anti-malware technology complements FIRE's cloud-based technologies, and management believes it will be able to leverage Immunet's technology as a platform. Sourcefire will retain all full-time Immunet personnel, including its founders, who will continue development of an enterprise endpoint product that is expected to be released in late 2011. Sourcefire's security platform buildout continues, and with multiple levers to monetize, we believe sustainable 20%-plus growth is achievable. Market cap: $660.1 million.
