The Electronic Frontier Foundation (EFF) is a U.S. 501(c)(3) nonprofit organization, founded on July 10, 1990, and headquartered in San Francisco, that defends civil liberties in the digital world through impact litigation, policy analysis, grassroots activism, and technology development. With 79 employees, it punches well above its size by shaping legislation, fighting surveillance in federal court, and building free tools used by millions. Its work has produced landmark legal precedents on email privacy, encryption, and internet speech. The Atlas of Surveillance database, compiled by more than 1,000 students and volunteers, had captured more than 15,000 law-enforcement surveillance deployments across the United States as of 2025.

Origins
The EFF grew out of a specific crisis rather than an abstract mission. In 1990, a series of U.S. Secret Service raids targeted people suspected of distributing an illegally copied document describing the emergency 911 telephone system, known as the E911 document. One raid fell on Steve Jackson Games, a game-book publisher whose computers were seized even though the company had committed no crime connected to the investigation. The three founders, John Gilmore, John Perry Barlow, and Mitch Kapor, had all crossed paths through the Whole Earth ‘Lectronic Link, an online community now known as WELL.com. They formalized the EFF in July 1990 to ensure that the rights people held in the physical world would not evaporate the moment their lives moved online.
Landmark Legal Cases
Steve Jackson Games v. Secret Service became the EFF’s first major case and produced the first ruling that electronic mail deserves at least as much protection as telephone calls. The court found that law enforcement must obtain a warrant before seizing and reading private email messages, a finding that reframed how investigators could treat digital correspondence.
In February 1995, EFF filed Bernstein v. U.S. Department of Justice on behalf of a researcher who wanted to publish encryption software. A federal court eventually ruled for the first time that software source code is speech protected by the First Amendment. The decision forced changes in U.S. export regulations on encryption software, opening the door to the widespread deployment of strong cryptography.
EFF was among the civil-liberties groups that challenged the internet indecency provisions of the Communications Decency Act of 1996. The U.S. Supreme Court sided with the challengers in Reno v. American Civil Liberties Union in 1997, striking down those provisions. EFF later supported the ACLU in a parallel challenge to the Child Online Protection Act of 1998, which ended in another Supreme Court victory in Ashcroft v. American Civil Liberties Union in 2004.
In 2008, EFF filed Jewel v. NSA on behalf of AT&T customers, challenging the National Security Agency’s dragnet surveillance of Americans’ communications using AT&T’s facilities. The case wound through the courts for years. In February 2016, district court judge Jeffrey White authorized EFF to conduct discovery against the NSA, making it the first time any party had been allowed to gather factual evidence from the agency in a case involving its warrantless surveillance program.
Accountability Campaigns
Not every EFF battle takes place in federal court. In the Sony Rootkit case, EFF held Sony BMG accountable for shipping CDs that secretly installed software on customers’ computers, creating security vulnerabilities without their knowledge or consent. EFF’s pressure pushed Sony BMG to take the affected CDs off the market and settle a class-action lawsuit that forced the company to repair the damage it had caused.
In October 2025, EFF launched the Take Back CTRL campaign, aimed at challenging efforts to normalize online surveillance and censorship and at opposing what EFF describes as the use of technology to support authoritarian governance.
Tools and Technology
EFF’s Coders’ Rights Project protects programmers and security researchers who probe the edges of technology. The project provides education, legal defense, amicus briefs, and policy advice against threats arising from laws such as the Computer Fraud and Abuse Act and the Digital Millennium Copyright Act.
On the software side, EFF developed Certbot, a tool that automates obtaining and renewing HTTPS certificates, and HTTPS Everywhere, a browser extension built in collaboration with the Tor Project. HTTPS Everywhere automatically rewrote browser requests to use encrypted connections on sites that supported it, helping users communicate more securely in the years before HTTPS became near-universal. EFF also built the Atlas of Surveillance together with the Reynolds School of Journalism at the University of Nevada, Reno: a searchable database documenting drones, body-worn cameras, facial recognition systems, and automated license plate readers deployed by law enforcement agencies across the United States, reaching more than 15,000 documented deployments as of 2025.
Local Impact and Grassroots Work
EFF’s Local Impact Labs program, active in 2025, provided technical assistance to local officials and grassroots advocates seeking to refuse or dismantle harmful surveillance systems. During that period the program contributed to 853 automated license plate reader cameras being taken down or blocked across 24 municipalities nationwide.
The Pioneer Award
Since 1992, EFF has presented the Pioneer Award to individuals who have made significant contributions to empowering people online. Past recipients include Linus Torvalds, who received the award in 1998; Tim Berners-Lee, who received it in 2000; and Glenn Greenwald and Laura Poitras, who shared it in 2013. The 1997 award went to actress Hedy Lamarr and composer George Antheil for their earlier work on frequency-hopping spread-spectrum communication, with Antheil’s recognition coming posthumously.
Recognition and Leadership
At DEF CON 32 in August 2024, EFF became the first organization to receive the Uber Contributor Award, which recognizes its work in education and litigation as ‘Defenders of the Hacker Spirit.’
On June 1, 2026, Nicole Ozer, a legal expert on privacy, surveillance, artificial intelligence, and digital speech, became EFF’s executive director, succeeding Cindy Cohn.

Secret Service, arose from a 1990 raid by U.S. Secret Service agents who seized computers from a game-book publisher while searching for an illegally distributed document about the 911 emergency telephone system, not evidence of any crime committed by the games company itself.
