Maximum Security:

## A Hacker's Guide to Protecting Your Internet Site and Network

# Security Consultants

This appendix is a bit different from the one that preceded it. It is designed to provide you with contact points for security vendors. However, there are several things you should know about this list. First, the manner in which it was generated was extremely unorthodox. It differs from other such lists in several ways.

In March 1997, I posted a message to several security lists and newsgroups. In the message, I explained that the book was written anonymously. I stated that any security vendor or consultant who wished to be listed in this appendix should forward his or her information to me or to Sams.net. That listing would be printed free of charge.

The idea was basically to allow you to look through the listing and find a security consultant or vendor near you. The responses were amazing. The vast majority of the vendors on the list are well known in the security community. For example, you might remember that I mentioned Gemini Computers earlier in this book. Gemini creates one of the two most secure products on Earth. That it decided to place a listing in my book is extraordinary, and an honor for me.

Unfortunately, the list is short (perhaps 60 entries, give or take a few). Nevertheless, these individuals and corporations are truly in the know. Each day, they supply security services to thousands of companies across the globe. Many provide such services to Fortune 500 companies.

Some consultants and companies that also perform many superb security services were reticent to placing a listing; they felt that placing a listing in a book sight unseen was unwise. (What if I was a complete crackpot and my book was terrible? Why be associated with such a book?) This is unfortunate. So the absence of a vendor's name on this list means nothing and should not reflect on that vendor's capabilities. There are several hundred companies of equal caliber to those listed here.

> NOTE: Sams.net cannot make any representations or warranties regarding the technical expertise of the companies listed in this appendix. However, I have conducted concentrated surveillance of security groups and lists for approximately two years, and nearly all the companies listed are recognized within the security community. I would urge you to track them by e-mail address and URL. From this, you can easily verify their reputations on the Internet.

## The Listings

The format of the listings was simple. Vendors were told to provide all their vitals (name, address, contact person, telephone, fax, and URL). They were also asked to take three lines to explain what services they offer. Except for corrections of spelling errors, the listings here appear exactly as they were received.
