Revenue for the first quarter of 2006 increased 16% to $87.5 million from $75.6 million for the first quarter of 2005. Net income in accordance with Generally Accepted Accounting Principles (GAAP) for the first quarter of 2006 was $5.3 million, or $0.07 per diluted share.

“The first quarter of 2006 was a record quarter for RSA Security. In addition to generating the highest ever quarterly revenue in the Company’s history, we had our best ever first quarter in terms of bookings,” said Art Coviello, president and chief executive officer of RSA Security. “We built on our strong fourth quarter results in the enterprise and consumer businesses, and we generated significant traction from the successful integration of the Cyota acquisition. With increasing awareness and global regulation driving the continued adoption of strong authentication, I am excited about our prospects for the year to come.”

First-Quarter 2006 Financial Highlights

• Revenue and Bookings: RSA Security generated $87.5 million in revenue for the first quarter of 2006, compared to $75.6 million in revenue for the first quarter of 2005. RSA Security’s book-to-bill ratio for the first quarter was approximately 1.1 to 1, compared to a book-to-bill ratio of 1.0 to 1 during the first quarter of 2005.
• Net Income: For the first quarter of 2006, the Company generated GAAP net income of $5.3 million, or $0.07 per diluted share, and non-GAAP net income of $10.5 million, or $0.14 per diluted share.
• Backlog, Deferred Revenue and Estimated Unrecognized Revenue from Managed Service Contracts: The Company closed the quarter with $119.1 million in combined deferred revenue, backlog and estimated unrecognized revenue from managed service contracts, a 8% increase from the $110.8 million balance at December 31, 2005.
• Cash Position and Share Repurchase: Cash, cash equivalents, and marketable securities increased to $208.2 million at March 31, 2006 from $187.8 million at December 31, 2005. During the quarter, in accordance with the Company’s approved stock buyback plan, RSA Security repurchased 82,300 shares of its common stock for $1.2 million. Under the board approved share repurchase plan, RSA Security can repurchase an additional 6.4 million shares of RSA Security common stock through June 30, 2006.

First Quarter 2006 Operational Highlights

• Customers: RSA Security closed business with more than 6,000 customers in the first quarter, including approximately 800 new customers. The Company shipped over 1.7 million authentication credentials during the first quarter, up 11% from the fourth quarter of 2005, the Company’s previous record quarter for credential shipments. Of the authentication credentials shipped during the quarter, approximately 620,000 credentials were consumer related.
• Partners: RSA Security introduced a strategy to enable ubiquitous strong authentication by integrating RSA SecurID® authentication into everyday devices and software such as mobile phones, PDAs, USB thumb drives and mobile flash memory cards. By transforming these devices into strong authentication platforms, RSA SecurID authentication can move beyond self-contained hardware tokens to an unprecedented array of devices. In the first quarter of 2006, RSA Security announced relationships with several flagship partners including M-Systems, Motorola, SanDisk, Research in Motion (RIM) and others.
• Products and Solutions: In February, RSA Security announced RSA® SecurID® Appliance 2.0, which scales to 50,000 users, making it possible to meet the demands of enterprise customers seeking an appliance-based solution. During the first quarter the Company sold approximately 300 RSA SecurID Appliances, of which 50 percent were to new customers. Since the appliance can be deployed in as few as 15 minutes, with few IT resources, it is becoming a significant driver of growth in the capture of new customers.
  
  

  The Company also launched the RSA SecurID Toolbar Token, an easy-to-use strong authentication option delivered in the familiar Web browser toolbar format. With the toolbar, users navigate to the Web site protected by RSA SecurID technology, and then utilize the token code appearing in the toolbar, offering consumer-facing organizations a simple way to arm their customers with stronger protection online.

• Industry Leadership: RSA Security hosted the 15th annual RSA® Conference in San Jose in February. This industry-leading conference drew scores of exhibitors and over 14,000 attendees, with full conference attendance up over 10% from the prior year. Keynote speakers included industry leaders such as John Chambers, president and chief executive officer, Cisco Systems; Bill Gates, chairman of the board and chief software architect, Microsoft Corp.; Scott McNealy, chairman and chief executive officer, Sun Microsystems; and John Thompson, chairman of the board and chief executive officer, Symantec Corporation.
  
  Additional conferences to be held during the year include RSA Conference Japan, in Tokyo April 26 and 27, RSA Conference China, in Beijing in November and RSA Conference Europe in Nice, France October 23 through October 25. For more information about RSA Conferences, visit www.RSAConference.com.

Use of Non-GAAP Financial Measures

The Company is providing non-GAAP financial measures as the Company believes that these figures are helpful in allowing investors to more accurately assess the ongoing nature of RSA Security’s core operations. Further, management from time to time provides guidance with regard to future expectations of the business; both these GAAP and non-GAAP measures will assist investors in reconciling this forward looking guidance to actual results. Additionally, the Company is providing GAAP and non-GAAP measures in order to illustrate the impact of recent changes in accounting regulations, and to assist investors with the comparison of current and prior period results.

The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management uses both GAAP and non-GAAP measures when evaluating the business internally and therefore felt it important to make these same metrics available to investors.

GAAP earnings per share for the first quarter of 2006 include pre-tax charges as follows: a restructuring charge of $2.6 million related to the Company’s previously announced restructuring of its engineering resources, stock based compensation charges of $2.8 million related to the Company’s adoption of Statement of Financial Accounting Standards No. 123R, “Share Based Payment” (SFAS 123R) and $1.3 million of amortization of intangible assets primarily related to intangible assets acquired as a result of the Company’s acquisition of Cyota.
