Webroot Inc. is an American privately-held cybersecurity software company that provides Internet security for consumers and businesses. The company was founded in Boulder, Colorado, US and is now headquartered in Broomfield, Colorado, and has US operations in San Mateo and San Diego, and globally in Australia, Austria, Ireland, Japan and the United Kingdom. The international headquarters is located in Dublin, Ireland.
Webroot was founded on 5 July 1997 when Steven Thomas and his girlfriend Boulderite Kristen Tally  launched Webroot's first commercial product, a trace removal agent called Webroot Window Washer. Investors include venture capital firms such as Technology Crossover Ventures, Accel Partners and Mayfield.
In 2002, Webroot launched a spyware blocking and removal product called Webroot Spy Sweeper. The company introduced antivirus protection with the launch of Spy Sweeper with AntiVirus in 2006. In October 2007, Webroot AntiVirus with AntiSpyware and Desktop Firewall was released with added firewall protection feature.
Webroot entered the enterprise market in 2004 with the launch of Webroot Spy Sweeper Enterprise, which combined Spy Sweeper with technology that enables IT administrators to deploy antispyware protection across an entire network.
In October 2008, Webroot launched its first consumer security suite, Webroot Internet Security Essentials, in the United States. The international release of the security suite followed in early 2009.
In May 2010 Webroot announced plans to open its international headquarters in Dublin, Ireland. In July 2010 Webroot Internet Security Complete 2011 was released, including antivirus and antispyware protection, firewall capabilities, online back-up, password management licensed from LastPass, protection against identity theft and credit card monitoring for US customers.
In September 2010 Webroot opened a regional office in Leidschendam, The Netherlands which is primarily aimed at distributing Webroot's enterprise security-as-a-service (SaaS) products to businesses.
Webroot Mobile Security for Android was launched on April 5, 2011 for smartphones and tablets, with a free basic version and a paid premium version. The app is designed to protect against viruses from apps, threats delivered via web browsing and against the threats created when mobile devices are lost. The SecureAnywhere products launched on October 4, 2011, and the mobile security offerings were expanded to include the iOS mobile operating system.
In October 2011 Webroot launched a new generation of their products, using Prevx cloud technology. This included three basic products for Windows (SecureAnywhere AntiVirus, Essentials and Complete 2012) and security for Android and iOS mobile devices. In February 2012 products for businesses were added.
On February 7, 2019 Carbonite, Inc. announced that it entered into a definitive agreement to acquire Webroot. On March 26, 2019, Carbonite closed its acquisition of Webroot, with a purchase price of $618.5 million in cash.

AV-Comparatives gave nine vendors, including Webroot, its highest award in its July 2012 Anti-Phishing Test, in which Webroot took 9th place among 18 products tested for efficacy in blocking phishing websites. In AV-Comparatives's Performance Test for October 2012, Webroot had the best PCMark score, having the lightest impact out of 20 products tested on a Windows 7 64-bit machine.
Webroot had the worst results out of 20 products tested by AV-Comparatives in the September 2012 File Detection Test of Malicious Software, both in terms of malware detection rates and false alarms. Webroot detected less than 80 percent of viral samples, much worse than the 94.4 percent rate of the second-lowest detecting product. Webroot inappropriately flagged 210 clean files, raising as many false positives as the other 19 products tested combined. According to AV-comparatives, the "results and misses have been confirmed with several tests and also by the vendor."
PC Magazine has awarded Webroot SecureAnywhere 19 times with Editor's Choice and Security Product of the Year, its highest award given to security and software programs. In PC Magazine's test for 2013, Webroot was found by PC Magazine staff to have the best score in malware blocking tests, malware removal tests, speed of scans, and installation speed. In the 2014 test, PCMag found "Webroot's detection rate of 89 percent and overall malware cleanup score of 6.6 points are both tops among products tested using this same malware collection."
In 2014, PassMark Software, a software and hardware performance benchmarking company, benchmarked Webroot SecureAnywhere Business Endpoint Protection and Webroot SecureAnywhere AntiVirus using 13 performance metrics. In both tests, Webroot products were found to outperform competitors in a variety of metrics, including scan times, CPU usage, and others, earning the highest overall score in both tests.
During November 2016's evaluation of mobile security products for Android AV-TEST has given Webroot's SecureAnywhere Mobile product a "Protection Score" of 3.5 out of 6, placing it near the bottom of all 26 products evaluated in this test in terms of protection against malware. Both the "Detection of the latest Android malware in real-time" and "Detection of the latest Android malware discovered in the last 4 weeks" scores were below the "Industry Average" score.
In the October 2017 AV-Comparatives performed a "Head-to-Head Comparison" between products from VIPRE and Webroot, the Webroot SecureAnywhere product was only able to achieve 86.4% "Protection Rate", compared to VIPRE Cloud's 100% rate. The test was performed using a test set of 316 live malicious URLs found in the field.
During the January 2018 test of 84 various Android antimalware apps by AV-Comparatives, Webroot Security Premier has detected 99.7% of all antimalware samples, placing it below 30 other tested apps which showed better detection rates.
