Keith B. Alexander

On April 13, 2016, President Obama announced Alexander as a member of his Commission on Enhancing National Cybersecurity.

Alexander gave the most comprehensive interview of his career, which spanned some 17,000 words, on 8 May 2014 to the Australian Financial Review journalist Christopher Joye, which was subsequently cited by Edward Snowden. The full transcript, which covers NSA operations, Snowden, the metadata debates, encryption controversies, and Chinese and Russian spying, has been published online. On Snowden, Alexander told Joye: "I suspect Russian intelligence are driving what he does. Understand as well that they're only going to let him do those things that benefit Russia, or stand to help improve Snowden's credibility". Wired magazine said the AFR interview with Alexander showed he was defending the stock-piling of zero-days while The Wall Street Journal and other media focused on Alexander's claims about Snowden working for Russian intelligence. In July 2012, in response to a question from Jeff Moss, founder of the DEF CON hacker convention, "... does the NSA really keep a file on everyone?," Alexander replied, "No, we don't. Absolutely no. And anybody who would tell you that we're keeping files or dossiers on the American people knows that's not true."

In May 2014, after his retirement from NSA, Alexander founded IronNet Cybersecurity. IronNet provides cybersecurity coverage for private-sector companies using its IronDefense program and a team of cybersecurity analysts and experts. The company is headquartered in Fulton, Maryland with offices in Frederick, Maryland, McLean, Virginia, and New York City. In October 2015, IronNet received $32.5 million in funding from Trident Capital Cybersecurity (now ForgePoint Capital) and Kleiner Perkins Caufield & Byers in a Series A investment. In May 2018, IronNet raised an additional $78 million in a round led by C5 Capital alongside existing investors ForgePoint Capital and Kleiner Perkins Caufield & Byers. Alexander maintains his role as CEO of IronNet today.

In the fall of 2014 Alexander told a public forum that someone else had claimed a $9,000 IRS refund in his name, and that the thieves used his identity to apply for about 20 credit cards.

Alexander announced his retirement on October 16, 2013. His retirement date was March 28, 2014. In May 2014, Alexander founded IronNet Cybersecurity, a private-sector cybersecurity firm based in Fulton, Maryland.

In June 2013, the National Security Agency was revealed by whistle-blower Edward Snowden to be secretly spying on the American people with FISA-approved surveillance programs, such as PRISM and XKeyscore.

On October 16, 2013, it was publicly announced that Alexander and his deputy, Chris Inglis were leaving the NSA.

According to Siobhan Gorman of The Wall Street Journal, a government official stated that Alexander offered to resign after the 2013 global surveillance disclosures first broke out in June 2013, but that the Obama Administration asked him not to.

Alexander delivered the keynote address at Black Hat USA in July 2013. The organizers describe Alexander as an advocate of "battlefield visualization and 'data fusion' for more useful intelligence". He provided them with this quote:

On June 6, 2013, the day after Snowden's revelations, then-Director of National Intelligence James Clapper released a statement admitting the NSA collects telephony metadata on millions of Americans telephone calls. This metadata information included originating and terminating telephone number, telephone calling card number, IMEI number, time and duration of phone calls.

Alexander announced his retirement on October 16, 2013. His retirement date was March 28, 2014, and his replacement was U.S. Navy Vice Admiral Michael S. Rogers.

Alexander was inducted into the NPS Hall of Fame in 2013.

In March 2012, in response to questions from Representative Hank Johnson during a United States Congress hearing about allegations made by former NSA officials that the NSA engages in collection of voice and digital information of U.S. citizens, Alexander said that, despite the allegations of "James Bashford" [sic] in Wired magazine, the NSA does not collect that data.

On July 9, 2012, when asked by a member of the press if a large data center in Utah was used to store data on American citizens, Alexander stated, "No. While I can't go into all the details on the Utah Data Center, we don't hold data on U.S. citizens."

At DEF CON 2012, Alexander was the keynote speaker; during the question and answers session, in response to the question "Does the NSA really keep a file on everyone, and if so, how can I see mine?" Alexander replied "Our job is foreign intelligence" and that "Those who would want to weave the story that we have millions or hundreds of millions of dossiers on people, is absolutely false ... From my perspective, this is absolute nonsense."

Andy Greenberg of Forbes said that NSA officials, including Alexander, in the years 2012 and 2013 "publicly denied—often with carefully hedged words—participating in the kind of snooping on Americans that has since become nearly undeniable." In September 2013, Alexander was asked by Senator Mark Udall if it is the goal of the NSA to "collect the phone records of all Americans", to which Alexander replied:

Alexander was confirmed by the United States Senate for appointment to the rank of general on May 7, 2010, and was officially promoted to that rank in a ceremony on May 21, 2010. Alexander assumed command of United States Cyber Command in the same ceremony that made him a four-star general.

By 2008, the Regional Gateway was effective in providing information about Iraqi insurgents who had eluded less comprehensive techniques. This "collect it all" strategy introduced by Keith Alexander is believed by Glenn Greenwald of The Guardian to be the model for the comprehensive world-wide mass archiving of communications which NSA had become engaged in by 2013.

Alexander became a three-star general. In 2005, Donald Rumsfeld, secretary of defense, named him Director of the National Security Agency. There, according to Bamford, Alexander deceived the House Intelligence Committee when his agency was involved in NSA warrantless wiretapping. Also during this period, Alexander oversaw the implementation of the Real Time Regional Gateway in Iraq, an NSA data collection program that consisted of gathering all electronic communication, storing it, and then searching and otherwise analyzing it. A former senior U.S. intelligence agent described Alexander's program: "Rather than look for a single needle in the haystack, his approach was, 'Let's collect the whole haystack. Collect it all, tag it, store it ... And whatever it is you want, you go searching for it."

In 2004, along with Alberto Gonzales and others in the George W. Bush administration, Alexander presented a memorandum that sought to justify the treatment of those who were deemed "unlawful enemy combatants".

Alexander's assignments include the Deputy Chief of Staff (DCS, G-2), Headquarters, Department of the Army, Washington, D.C. from 2003 to 2005; Commanding General of the United States Army Intelligence and Security Command at Fort Belvoir, Virginia from 2001 to 2003; Director of Intelligence (J-2), United States Central Command, MacDill Air Force Base, Florida from 1998 to 2001; and Deputy Director for Intelligence (J-2) for the Joint Chiefs of Staff from 1997 to 1998. Alexander served in a variety of command assignments in Germany and the United States. These include tours as Commander of Border Field Office, 511th MI Battalion, 66th MI Group; 336th Army Security Agency Company, 525th MI Group; 204th MI Battalion; and 525th Military Intelligence Brigade.

In 2003, Alexander was named deputy chief of staff for intelligence for the United States Army. The 205th MI Brigade involved in the Abu Ghraib torture and prisoner abuse in Baghdad, Iraq was part of V Corps (US) and not under Alexander's command. Testifying to the Senate Armed Services Committee, Alexander called the abuse "totally reprehensible" and described the perpetrators as a "group of undisciplined MP soldiers". Mary Louise Kelly, who interviewed him later for NPR, said that because he was "outside the chain of command that oversaw interrogations in Iraq", Alexander was able to survive with his "reputation intact".

Alexander headed the Army Intelligence and Security Command, where in 2001 he was in charge of 10,700 spies and eavesdroppers worldwide. In the words of James Bamford, who wrote his biography for Wired, "Alexander and the rest of the American intelligence community suffered a devastating defeat when they were surprised by the attacks on 9/11." Alexander's reaction was to order his intercept operators to begin to monitor the email and phone calls of American citizens who were unrelated to terrorist threats, including the personal calls of journalists.

Alexander worked on signals intelligence at a number of secret National Security Agency bases in the United States and Germany. He earned a Master of Science in business administration in 1978 from Boston University, a Master of Science in systems technology (electronic warfare) and a Master in Science in physics in 1983 from the Naval Postgraduate School, and a Master of Science in national security strategy from the National Defense University. He rose quickly up the military ranks, due to his expertise in advanced technology and his competency at administration.

Alexander attended the United States Military Academy at West Point, and in his class were three other future four-star generals: David Petraeus, Martin Dempsey and Walter L. Sharp. Just before graduation in April 1974, Alexander married Deborah Lynn Douglas, who was a classmate in high school and who grew up near his family in Onondaga Hill. They had three children two daughters.

Additionally, Alexander Held key staff assignments as Deputy Director and Operations Officer, Executive Officer, 522nd MI Battalion, 2nd Armored Division; G-2 for the 1st Armored Division both in Germany and during the Gulf War, in Operation Desert Shield and Operation Desert Storm, in Saudi Arabia. He also served in Afghanistan on a peace keeping mission for the Army Deputy Chief of Staff for Intelligence.
