Kaspersky Lab

Kaspersky Lab (/kæˈspɜːrski/; Russian: Лаборатория Касперского, romanized: Laboratoriya Kasperskogo) is a Russian multinational cybersecurity and anti-virus provider company headquartered in Moscow, Russia. It was founded in 1997 by Eugene Kaspersky, Natalya Kaspersky and Alexey De-Monderik. Kaspersky Lab develops and sells antivirus, endpoint security, SIEM, XDR, and other cybersecurity products and services. The Kaspersky Global Research and Analysis Team (GReAT) has led the discovery of sophisticated espionage platforms conducted by nations, such as Equation Group and the Stuxnet worm. Their research has uncovered large-scale and highly technical cyber espionage attempts. Kaspersky also publishes the annual Global IT Security Risks Survey.

Kaspersky expanded abroad from 2005 to 2010 and grew to $822 million in annual revenues by 2024. In 2010, Kaspersky Lab ranked fourth in the global ranking of antivirus vendors by revenue. It was the first Russian company to be included into the rating of the world's leading software companies, called the Software Top 100 (79th on the list, as of June 29, 2012). In 2016, Kaspersky's research hubs analyzed more than 350,000 malware samples per day. In 2016, the software had about 400 million users and was one the largest market-share of cybersecurity software vendors in Europe.

The US government has alleged that Kaspersky has engaged with the Russian Federal Security Service (FSB)—ties which the company has actively denied. In 2017, the Trump administration issued a ban of Kaspersky software on federal civilian and military computers. In response to these and other allegations, Kaspersky began to solicit independent reviews and verification of its source code, and relocated core infrastructure and customer data from Russia to Switzerland. Multiple countries have banned or restricted their government agencies from using Kaspersky products, including Lithuania, the Netherlands, and the United States.

As of 2025, Kaspersky has over 30 offices in Europe, Middle East, Africa, Asia, and Latin America, and customers in over 200 countries.
