Since the firm's founding in 1978, Mr. Gezelter's work has often included architecting, designing, implementing, and maintaining secure applications and environments in a range of environments. Some of his have included:

• architecting, designing, and implementing numerous applications programs which leverage the inherant security facilities and capabilities of OpenVMS™ to maximize the security, correctness, and auditability of client applications while simultaneously reducing the size and complexity of the coding effort.
• supervising the creation of procedures for the creation and maintenance of user accounts in accord with established policies for secure computing, without imposing miniumal inconvenience on users.
• implementing numerous DCL procedures to address a wide range of client application and system management requirements. Have spoken extensively on the use of sophisticated DCL techniques to implement the security of applications environments operating on OpenVMS.
• implementing file and applications protections based upon Rights Identifiers and Access Control Lists which tightly controlled application and data access to trained and authorized personnel.
• speaking on systems management and internals of OpenVMS and related products at DECUS Symposia in the United States, Canada, Switzerland, France, and Turkey. Presentations have included both one hour sessions and full day seminars.
• authoring several articles on OpenVMS systems management, internals, and related areas. Articles have been published by Digital Systems Journal, Digital News, and Hardcopy.
