Slade married Gloria J. Slade who edits much of his work and is the editor of Slade's book reviews. Their grandchildren appear in the From field of every review, in 2008 from "Rob, grandpa of Ryan, Trevor, Devon & Hannah". He holds a bachelor's degree from the University of British Columbia, a master's in computer and information science education from the University of Oregon and a diploma in Christian studies from Regent College.

Slade became one of a small number of researchers who can be called the world's experts on malware. Fred Cohen named Slade's early work organizing computer viruses, software, BBS and book reviews Mr. Slade's lists. Slade is one of fewer than thirty people worldwide who are credited for contributions in the final version of the VIRUS-L FAQ, which, with the Usenet group comp.virus and the VIRUS-L mailing list, was the public group of record for computer virus issues from 1988 to 1995. Until 1996 he maintained the Antiviral Software Evaluation FAQ, a quick reference for users seeking antivirus software and a vendor contacts list. He was a contributor as well to at least three other group computer virus FAQs before the Web came to prominence. His books about viruses were first published in 1994 and 2001.

Slade advanced the field of computer forensics when through his antivirus research he found that the intentions and identity of virus authors can be discovered in their program code. He created the first course ever offered in forensic programming. His book Software Forensics was published in 2004 and his chapter on the subject is in print in the Information Security Management Handbook as of the fifth edition.

Today Slade is a consultant to businesses and government...among his client list are Fortune 500 companies and the government of Canada...as well as to educational institutions. He created curricula and taught courses for Simon Fraser University, MacDonald Dettwiler, and the University of Phoenix. Slade creates seminars for local, federal and international training groups. He is a senior instructor for ² where he develops courses in information security and quality assurance (QA) for those who seek certification. Slade himself is one of the world's approximately 60,000 CISSP, a certification used in private industry as well as, at least in the United States, in government and defense.

Slade moved his online security glossary in 2006 to the book Dictionary of Information Security. Virus Bulletin remarked about the unusual collection of five forewords, "that so many acknowledged experts are willing to contribute says something about the author's standing in the field"...the forewords were written by Fred Cohen, Jack Holleran, Peter G. Neumann, Harold Tipton and Gene Spafford. The dictionary is considered to be "dependable baseline definitions" and a "citable, common source".

Slade has "surveyed most of the literature" in his field and shared his knowledge in the Internet Review Project, the published book reviews for which he is perhaps most widely known. He reviews other works but gave first priority to information security. His reviews are often critical...to the project FAQ question, "Don't you like any books?", Slade replied that he may be cruel but is fair.
