Splunk Appoints Tim Mather as CISO and VP of Security and Compliance Markets

Mather to Lead Security Strategy and Solutions; Speaking at RSA Conference 2013

RSA CONFERENCE 2013, SAN FRANCISCO - February 25, 2013 Splunk Inc. (NASDAQ: SPLK), the leading software platform for real-time operational intelligence, today announced the appointment of Tim Mather as chief information security officer (CISO) and vice president of security and compliance markets. With nearly 18 years of experience, Mather will serve as the team leader for the company's initiatives in security and compliance, leading the charge to help Splunk customers secure their organizations by using machine data to gain operational intelligence. Mather will report to Steve Sommer, Splunk's chief marketing officer.

"Tim is a valuable addition to the Splunk team as we continue to strengthen our position and invest in the security market," said Sommer. "Tim will also help further secure Splunk's own IT infrastructure, information and intellectual property--using Splunk software. His insight and experience will play an important role in accelerating the company's security initiatives."

"Splunk is at the forefront of security intelligence, helping organizations of all sizes analyze their machine data in real time to uncover the increasing number of known and unknown threats," said Mather. "More than 1,500 organizations, many with multiple use cases, already rely on Splunk technology to address the growing threats in security. These are threats that Security Information and Event Management solutions (SIEMs) are often times ill-equipped to combat in today's dynamic environment in which scale, file types and attack methods are constantly changing."

Prior to Splunk, Mather spent three years as senior advisor at I-4 (International Information Integrity Institute) - a KPMG UK entity focused on information security, including the use of big data for security and securing the cloud. A long-time information security practitioner, Mather has served in senior roles at RSA Security, Symantec, VeriSign and Apple. During his career, he has attained such credentials as CISSP, CISA and CISM, and he is a member of several security associations. Mather has also co-authored two books on security: "Cloud Security and Privacy: An Enterprise Perspective on Risks and Compliance" (O'Reilly) and "The Executive Guide to Information Security: Threats, Challenges, and Solutions" (Addison-Wesley).

Mather holds multiple Master's degrees, including a M.S. in Information Assurance from Brandeis University, a M.S. in National Security Studies from Georgetown University and a M.S. in International Policy Studies from Monterey Institute. He earned a Bachelor's Degree in Political Economics from the University of California, Berkeley.

Mather is leading two speaking sessions at RSA Conference 2013 this week at Moscone Center in San Francisco. 'Cloud Assurance Frameworks - Which One's Really Relevant?' is scheduled for Wednesday, February 27 at 8:00 a.m. PT in room 305. 'Stateless Architecture for Smaller IT and Risk Footprint' is scheduled for Thursday, February 28 at 1:40 p.m. PT in room 105.
