# HackerOne

HackerOne Inc. is a company specializing in cybersecurity, specifically attack resistance management, which blends the security expertise of ethical hackers with asset discovery, continuous assessment, and process enhancement to find and close gaps in the digital attack surface. It was one of the first companies to embrace and utilize crowd-sourced security and cybersecurity researchers as linchpins of its business model; pioneering bug bounty and coordinated vulnerability disclosure. As of December 2022, HackerOne's network had paid over $230 million in bounties. HackerOne's customers include The U.S. Department of Defense, General Motors, GitHub, Goldman Sachs, Google, Hyatt, Lufthansa, Microsoft, MINDEF Singapore, Nintendo, PayPal, Slack, Twitter, and Yahoo.

## History

In 2011, Dutch hackers Jobert Abma and Michiel Prins attempted to find security vulnerabilities in 100 prominent high-tech companies. They discovered flaws in all of the companies, including Facebook, Google, Apple, Microsoft, and Twitter. Dubbing their efforts the "Hack 100", Abma and Prins contacted the at-risk firms. While many firms ignored their disclosure attempts, the COO of Facebook, Sheryl Sandberg, passed on the warning to their head of product security, Alex Rice. Rice, Abma and Prins connected, and together with Merijn Terheggen founded HackerOne in 2012. In November 2015, Terheggen stepped down from his role as CEO and was replaced by Marten Mickos. In November 2013, the company hosted a program encouraging the discovery and responsible disclosure of software bugs. Microsoft and Facebook funded the initiative, known as the Internet Bug Bounty project. By June 2015, HackerOne's bug bounty platform had identified approximately 10,000 vulnerabilities and paid researchers over $1 million in bounties. In September 2015, the company launched a Vulnerability Coordination Maturity Model, which then-policy chief Katie Moussouris described as “an important effort from HackerOne to codify some reasonable minimum standards on how organizations handle incoming, unsolicited vulnerability reports.” In April 2017, the company announced 240% year-over-year customer growth in Europe, and the subsequent opening of additional European offices to serve increasing customer demand.
In April 2022, HackerOne acquired PullRequest, a code-review-as-a-service platform.

## Funding

In May 2014, HackerOne received $9 million (USD) in Series A funding from venture capital firm Benchmark. A $25 million Series B round was led by New Enterprise Associates. Angel investors include Salesforce CEO Marc Benioff, Digital Sky Technologies founder Yuri Milner, Dropbox chief executive Drew Houston and Yelp CEO Jeremy Stoppelman. A Series C round led by Dragoneer Investment Group netted $40 million in February 2017 for a total of $74 million in investments to date. In April 2017, European-based venture capital fund EQT Ventures invested in the $40 million Series C funding round. In 2019, the company raised $36 million in Series D funding led by Valor Equity Partners.

## U.S. Department of Defense Programs

In March 2016, the U.S. Department of Defense (DoD) launched an initiative dubbed "Hack the Pentagon" using the HackerOne platform. The 24-day program resulted in the discovery and mitigation of 138 vulnerabilities in DoD websites, with over $70,000 (USD) in bounties paid to participating researchers.
In October of the same year, DoD developed a Vulnerability Disclosure Policy (VDP), the first of its kind created for the U.S. government. The policy outlines the conditions under which cybersecurity researchers may legally explore front-facing programs for security vulnerabilities. The first use of the VDP launched as part of the "Hack the Army" initiative, which was also the first time this branch of the U.S. military welcomed hackers to find and report security flaws in its systems.
The Hack the Army initiative resulted in 118 valid vulnerability reports; 371 participants, including 25 government workers and 17 military personnel, took part. Approximately $100,000 (USD) in total was awarded to participating researchers.
In May 2017, DoD extended the program to "Hack the Air Force". This program led to the discovery of 207 vulnerabilities, netting more than $130,000 (USD) in paid bounties. As at the end of 2017, DoD had learned of and fixed thousands of vulnerabilities through their vulnerability disclosure initiatives.

## Events and live hacking

In February 2017, HackerOne sponsored an invitation-only hackathon, gathering security researchers from around the world to hack e-commerce sites Airbnb and Shopify for vulnerabilities. This was the second such hackathon, with the company hosting one in Las Vegas in August 2016 during the Black Hat Security Conference. In 2018, HackerOne hosted Live Hacking events in cities across the US and Asia. Asia (India) representatives won the first place with $1 million bounty cash been awarded to Mohana Rangam . And over $1 million in bounty cash was awarded at the next events, with Oath Inc. (now called Verizon Media) paying over $400,000 in bounties during a single event in San Francisco, CA in April 2018.
In October 2017, HackerOne hosted their first conference, called Security@ San Francisco. The 200-attendee event included speakers from DoD, General Motors and Uber and also featured talks from hackers.

## Courses

HackerOne has an online course to help people find bugs in a security system and other cybersecurity techniques. Each crowd-source security platform will have a different approach and a specific goal it focuses on. HackerOne primarily focuses on penetration testing services with security certifications, including ISO 27001 and FedRAMP authorization. While others in the field, like Bugcrowd, focus on attack surface management and a broad spectrum of penetration testing services for IoT, API, and even networks.

## Locations

HackerOne is headquartered in San Francisco. The company maintains a development office in Groningen, Netherlands. In April 2017, the company announced the addition of offices in London, UK and Germany.
