Patricia Arquette as Dr. Avery Ryan, a
deputy director of the FBI. Avery was a renowned psychologist in New York when her professional database was hacked, resulting in the death of a patient. This, coupled with the recent death of her daughter, led Avery to leave New York, and found the FBI's Cyber Crime Division. As Special Agent in Charge, Avery heads a team of former cyber criminals and federal agents who travel nationwide in search of the criminals who work on the dark net. After several years working under Simon Sifter, Ryan was promoted to deputy director of the FBI. Following the death of her daughter, Ryan divorced her husband, though the two later reconnect and begin a romantic relationship. Following the dissolution of her hack-for-good program, Avery begins recruiting young hackers to work within CTOC (Cyber Threat Operations Center). •
James Van Der Beek as Elijah Mundo, a Senior FBI Field Agent. Assigned to Ryan's Cyber division, Mundo is a former U.S. Marine, and an expert in battlefield
forensics,
weaponry, vehicles, and bombs. After a short separation from his wife, Elijah filed for divorce, though the two have since reconciled. He is an avid
gamer, and because of this he is all too aware of the dangers that lurk on the internet. As a field agent, Mundo is much more hands on than his counterparts in detaining and interviewing suspects. During the second season, Mundo's father was diagnosed with cancer, causing him to confide in a barmaid who later begins stalking him. In "Legacy", she is shot and killed by Russell. Elijah has one daughter. •
Peter MacNicol as Simon Sifter (season 1), an FBI Assistant Deputy Director. Simon works out of the FBI Headquarters in Washington and oversees Ryan and her Cyber division. Working his way up through the ranks investigating homicides, drive-bys, and gang warfare, Sifter has built up an array of contacts and connections that are invaluable to the FBI. He often acts as the clearinghouse between FBI Cyber and its intergovernmental counterparts. He is married with at least one child. Sometime following the first season, Sifter vacated his position. •
Shad Moss as Brody Nelson, an FBI analyst. Brody is a former
black hat hacker who was caught and later recruited by FBI Cyber as part of Ryan's "hack-for-good" program. After avoiding a prison sentence at the FBI's behest, the team are initially dubious of Brody's intentions. After struggling to sever his ties with the world of cyber crime, Nelson outs himself to the hacking community and proves himself to be a loyal and valued analyst. The team nicknamed him "Baby-Face". He is shown to be
arachnophobic. During season two, Nelson discovers that the FBI obtained evidence against him illegally, and as such his conviction is overturned. He later undergoes training at Quantico, and returns to Cyber as an agent. •
Charley Koontz as Daniel Krumitz, a Special Agent. Daniel notes his desire to join law enforcement began when his parents were murdered. He is a skilled analyst (Avery claims he is the best
white hat hacker in the world), and he is also brutally honest. He is a quick-witted introvert who specializes in technology, though he is also a trained field agent. He has one sister, named Francine, and has strong bonds with both Nelson and Ryan. Krumitz is often referred to by his nickname "Krummy". •
Hayley Kiyoko as Raven Ramirez, an FBI analyst. Raven, like Nelson, is a former black hat hacker recruited by Ryan as part of her "hack-for-good" program. At the start of the first season, she had been with the FBI for two years, and had become a specialist in social media investigations, international relations and cyber trends. Raven stated that, as a victim of cyber-bullying, she turned to hacking as a refuge from her tormentors. Raven is a trusted member of the team. Her hacker alias was Eclipse. After Avery's hack-for-good program is dissolved, Raven is awarded time-served, and thus spared prison. She later rejoins the FBI as a consultant specialist. •
Ted Danson as
D.B. Russell (season 2), the Director of Next Generation Cyber Forensics. D.B. is described as a "left-coast Sherlock Holmes", the son of hippies and a keen
forensic botanist. As a trained Crime Scene Investigator, Russell joins Cyber following a four-year stint as Director of the Las Vegas Crime Lab looking for a fresh start following a divorce and the death of his "soulmate"
Julie Finlay. Avery jokes that she offered Russell a job because of his selection of tea leaves and often mocks his Zen characteristics. Russell has four children and one granddaughter and, since joining Cyber, has expressed an interest in dating. He has formed close bonds with Daniel Krumitz and Brody Nelson. Russell later begins a relationship with Greer Latimore, then tenders his resignation in order to move to Paris. During the series finale, he is shot, but recovers from his injuries.
