to scan NFTs to look for malicious code or software in the file.

About the Author

Guy Rosefelt, Chief Product Officer, Sangfor Technologies.

Guy is Chief Product Officer for Sangfor Technologies. He has over
20 years experience (though some say it is one year’s experience
twenty times) in application and network security, kicking it off with 10
years in the U.S. Air Force, reaching rank of captain. After his time in
the USAF building the first fiber to the desktop LAN and other things
you would find in Tom Clancy novels, Guy worked at NGAF, SIEM,
WAF and CASB startups as well as big-name brands like Imperva
and Citrix. He has spoken at numerous conferences around the world
and in people's living rooms, written articles about the coming
Internet Apocalypse, and even managed to occasionally lead teams
that designed and built security stuff. Guy is thrilled to be in his current position at Sangfor -- partly
because he was promised there would always be Coke Zero in the breakroom. His favorite cake is
German Chocolate.

Guy can be reached online at [email protected] or on Twitter at @otto38dd and at our company
website www.sangfor.com.
