CSI: Cyber

• 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.

• Brent Sexton as Andrew Michaels, Avery's ex-husband. Andrew and she were married with a young daughter. Following the loss of their child, the two separated. In the season one finale, he notes that he has not seen Avery since she joined the FBI. During season two, he reconnects with Ryan after a hacker files a false death certificate in his name. Despite being engaged to another woman, he and Avery begin a romantic relationship once again.
• Kelly Preston as Greer Latimore, a former Secret Service agent turned private investigator. Greer first becomes known to the Cyber team after D.B. meets her in a bar. They later begin a romantic relationship and, after Greer is offered a job in Paris, D.B. tenders his resignation.
• Michael Irby as David Ortega, a U.S. Naval captain. David is a medical doctor stationed out of Washington, often seen assisting Avery Ryan's team's investigations. He is a trained medical examiner.
• Angela Trimbur as Francine Krumitz, Daniel's sister. Francine is hung up on the death of her parents. Although initially better at hiding it than her brother, she later shoots and kills their parents' murderer.
• Mckenna Grace as Michelle Mundo, Elijah's daughter. Referred to as "Mitchie" by her family, Michelle currently lives with her mother Devon, though she maintains a strong relationship with Elijah. She is initially the focus of a custody dispute.
• Alexie Gilmore as Devon Atwood, Elijah's wife. Devon and Elijah had, during the first season, recently separated. She is still very much in love with Elijah, as he is with her. The two decide to reconcile their romance, but keep it a secret from their daughter.
• Marcus Giamatti as Artie Sneed, a quirky amateur technology expert who occasionally helps the cyber unit with cases.
• Sean Blakemore as Director Marcus Silver, Avery's boss.
• Diogo Morgado as Miguel Vega: an Interpol agent, Avery's friend, who helped the team to stop Python.

On February 18, 2014, CBS announced plans to launch a new spin-off of the franchise titled CSI: Cyber.[33] Deadline.com reported that the series would focus on cyber investigations, as opposed to the forensic investigations seen in CSI, CSI: Miami, and CSI: NY, stating that "[Anthony E.] Zuiker has been at the forefront of entertainment’s digital conversion, experimenting in the arena for the past decade." Zuiker, who wrote digi-novel Level 26, spent time in Washington meeting with the CIA, FBI, and DOD as part of his research for his 2009 CBS project Cyber Crimes[34] (which was not picked up to series and likely inspired CSI: Cyber). It was announced that the series would be based on the work of producer Mary Aiken, a pioneering cyber psychologist.[35] The pilot episode was penned by Zuiker, Carol Mendelsohn, and Ann Donahue, and aired on April 30, 2014.[35] CBS announced that it had officially picked up the series on May 10, 2014.[36][37] The first season, comprising 13 episodes, premiered in March 2015. The second and final season consisted of 18 episodes.

The series is executive produced by creators Carol Mendelsohn, Anthony E. Zuiker, and Ann Donahue, former CSI: NY executive producer Pam Veasey (who acts as showrunner), Jonathan Littman, and Jerry Bruckheimer. Mary Aiken, on whom the show is based, is attached as a series producer. Peter MacNicol departed the main cast at the end of the first season,[38][39][40] whilst CBS announced on May 11, 2015, that CSI: Cyber was renewed for a second season. On June 25, 2015, Moss confirmed in an interview on The Project that season 2 would include 22 episodes.[41] Season 2 was reduced from 22 to 18 episodes, ending with the episode titled "Legacy".

On March 5, 2014, Patricia Arquette was cast as Special Agent Avery Ryan in a Spring episode of CSI. Ryan was described as being "tasked with solving high octane crimes that start out in the cyber world and play out in real life".[42] Charley Koontz was the next actor to be cast, playing a character then named Daniel Krummitz, an Agent that " rarely, if ever, goes home".[43] Peter MacNicol joined the cast on August 1, 2014, as Assistant Director Stavros Sifter, "a shrewd and savvy networker; a charmer with a hint of malice".[44] Koontz and MacNicol's characters were later renamed Daniel Krumitz and Simon Sifter, respectively. These announcements were swiftly followed by the casting of James Van Der Beek as the male lead, in the role of Elijah Mundo. Mundo was described as "an expert in battlefield forensics recruited by Patricia Arquette’s character".[45] Shad Moss announced his casting on August 20, 2014, via his Instagram account.[46] He was later confirmed to be playing "Baby Face" Nelson. Rounding out the original cast was Hayley Kiyoko as Raven Ramirez, described as a character who "will possess a dark secret in her front story which Ryan won’t even know until it’s too late". Kiyoko was cast on October 29, 2014.[47]

Following the cancellation of CSI: Crime Scene Investigation, it was announced that Ted Danson would be joining the Cyber cast as D.B. Russell, the newly appointed Director of Next Generation Cyber Forensics.[38][39][40][48]
