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.

[10][11] His book Software Forensics was published in 2004[12] and his chapter on the subject is in print in the Information Security Management Handbook as of the fifth edition.

[13] Today Slade is a consultant to businesses and government—among his client list are Fortune 500 companies and the government of Canada[14]—as well as to educational institutions.

He is a senior instructor for (ISC)² where he develops courses in information security and quality assurance (QA) for those who seek certification.

[14][15] Slade himself is one of the world's approximately 60,000[16] CISSPs,[13] a certification used in private industry as well as, at least in the United States, in government and defense.
