Thomas J. Venn - President and Co-Founder
A high technology verteran with more than thirty years of experience in office automation and computing systems, Tom Venn co-founded ISC in 1989. During his previous thirteen years with Xerox Corporation in Federal Government sales and management, he was a seven-time recipient of Xerox's highest award (President's Club) for sales achievement as a Major Account representative and as a District Systems Sales Manager.

At Xerox, Venn's responsibilities included the largest commercial and governmental accounts in the City of Chicago and the State of Wisconsin, and covered several product lines including the Memorywriter, local area networks, laser printing, personal computers, professional workstations, and word processing. Recognized as one of Xerox's most successful District Systems Sales Managers in the United States, Venn spent one year as a regional Marketing Manager for a 10 state area. As a result of these efforts, he received Xerox's Merit Achievement Award for distinguished contribution to the company.

A marketing major, Venn received a Bachelor's degree in Business Administration from the University of Notre Dame in 1974.

Michael J. Markowitz, Ph.D. - VP R&D and Co-Founder
A mathematician by training, Mike Markowitz became involved in public key cryptography in the early 1980s and co-founded ISC in 1989. He has helped design and/or author most of ISC's security products, and currently leads ISC's product development team.

In the 1990s, Markowitz served on NIST's Technical Advisory Committee to Develop a Federal Information Processing Standard for the Federal Key Management Infrastructure (TACDFIPSFKMI) and was Treasurer of the IEEE P1363 Public Key Cryptography Standards Committee for several years. He is a member of IACR, IEEE, and Phi Beta Kappa.

Markowitz received his B.S. and M.S. degrees from Lehigh University in 1973 and a Ph.D. in Mathematics from the University of California at Berkeley in 1979. He subsequently held an assistant professorship at the University of Notre Dame, an L.E. Dickson Instructorship at the University of Chicago, an assistant professorship at the University of Illinois at Chicago, and an associate professorship at Loyola University of Chicago. His published papers are in differential geometry and general relativity.

In 1999, Markowitz and Venn were awarded Vice President Gore's Hammer Award for their contribution as members of the GSA's FTS2001 team. ISC technology allowed FTS2001 bidders to digitally sign their proposals using smart cryptographic tokens and to submit them electronically. This paperless process saved the government an estimated "$1.5 million and 52,000 staff hours."

Roger S. Schlafly, Ph.D. - Senior Mathematician
Roger Schlafly began his work in cryptography in 1983 and has helped design or co-author all of ISC's public key encryption products.

Although Schlafly began his research career in differential geometry, he now holds several patents in Cryptography and Computer Science. He developed the numerical solutions package Eureka for Borland (later marketed as shareware under the name Mercury) and made significant contributions to the Quattro spreadsheet program. In 1995 Schlafly and Hass announced a solution of Plateau's century-old double-bubble conjecture (AMS ERA link, American Scientist article, Ann. of Math. article).

Schlafly received his B.S. and M.S. degrees from Princeton University and a Ph.D. in Mathematics from the University of California at Berkeley in 1980. He then joined the faculty of the University of Chicago with research interests in differential geometry and mathematical physics. Leaving academia in 1983, Schlafly spent a year at Hughes Aircraft Corporation working on air traffic control systems and then joined Borland International. He cemeted his relationship with ISC in 1996.

David DeVita, Esq. - VP and General Counsel
Dave DeVita's special expertise in software and technology law help ISC to remain in the forefront of the security industry.

DeVita received his B.A. from the University of Notre Dame in 1974 and his J.D. from the Ohio State University College of Law in 1978. He spent the next nine years as an Associate, then Partner, in the Cincinnati law firm of Dinsmore & Shohl. In 1987 DeVita cofounded DeVita and Howe, a general business law practice based in Cincinnati.

Andrew F. McDermott - Vice President of Sales
With more than twenty years of direct sales and sales management experience Andy McDermott has played a crucial role in the formulation of business development strategies at ISC since joining the company in 2002. He is also responsible for expanding our presence in all marketing arenas: federal/commercial and domestic/international.

Prior to joining ISC, Mr. McDermott worked as a private consultant to several SMB enterprises engaged in emerging manufacturing technologies. Mr. McDermott received a B.A. in English from the University of Notre Dame in 1974.
