5. Kaspersky Lab
Kaspersky Lab took the fifth position in IDC's analysis of global corporate endpoint security software with a 6.2 percent market share. The Moscow-based company faced a setback in April when Stephen Orenberg, a noted sales veteran who shaped the company's U.S. strategy as its president, stepped down along with the company's global chief technology officer and other key executives, citing a dispute over the company's strategy. Chris Doggett, who led the Kaspersky Lab North American channel program, was elevated to managing director of U.S. operations. But the company has been unveiling product improvements. In addition to introducing Security for Virtualization, Kaspersky Lab has added threat intelligence services and is encouraging partners to sell enhanced support options to clients. Company CEO Eugene Kaspersky's vision is to address critical infrastructure protection and continue to provide research on targeted attacks that use custom malware and zero-day exploits. He also invested in developing a separate Kaspersky Lab federal arm in an attempt to win U.S. federal government contracts for critical infrastructure protection. The company is also said to be testing anti-distributed, denial-of-service capabilities in Russia and Europe.
