RSA Security LLC, formerly RSA Security, Inc. and doing business as RSA, is an American computer and network security company. RSA was named after the initials of its co-founders, Ron Rivest, Adi Shamir and Leonard Adleman, after whom the RSA public key cryptography algorithm was also named. Among its products are the RSA BSAFE cryptography libraries and the SecurID authentication token. RSA is known for allegedly incorporating back doors developed by the NSA in its products. It also organizes the annual RSA Conference, an information security conference.
Founded as an independent company in 1982, RSA Security was acquired by EMC Corporation in 2006 for US$2.1 billion and operated as a division within EMC. When EMC was acquired by Dell Technologies in 2016, RSA became part of the Dell Technologies family of brands.
