This list was prepared by the National Computer Security Association. It lists 480 vendors of security products and services. Vendors are listed alphabetically by company name. Where two or more addresses for a vendor were available, I've provided both. Where I knew the firm's date of founding or number of employees, I've provided that. In some cases, two phone numbers are provided, in some cases, none. If no area code is provided, it is because it is a local call from DC,
and will be in the 301 area code (if Maryland), 703 area code (if VA), or 202 area code (if DC). The list is updated frequently. If you have any corrections or additions, please provide them. Our address: NCSA, Suite 309, 4401-A Connecticut Avenue, Washington, DC 20008. (202) 364-8252 (voice); (202) 364-1304 (BBS).
