Reference excerpt

NordVPN is a Lithuanian VPN service incorporated in Panama. Founded in 2012, NordVPN is developed by the Dutch company Nord Security (formerly Nordsec Ltd), a division of Cyberspace B.V. Nord Security is a cybersecurity software company that was initially supported by Tesonet, a Lithuanian startup accelerator and business incubator. Its offices are located in Lithuania, the United Kingdom, Panama, and the Netherlands. The service has applications for Microsoft Windows, macOS, Linux, Android, iOS, Android TV, and tvOS.

History NordVPN was established in 2012 by a group of childhood friends, with Eimantas Sabaliauskas and Tomas Okmanas at the helm. It presented an Android app in late May 2016, followed by an iOS app in June of the same year. In October 2017, it launched a browser extension for Google Chrome. The service launched applications for Android TV in 2018 and tvOS in 2023. As of January 2026, NordVPN operates 8,000+ servers covering 224 countries. In March 2019, it was reported that NordVPN received a directive from Russian authorities to join a state-sponsored registry of banned websites, which would prevent Russian NordVPN users from circumventing state censorship. NordVPN was reportedly given one month to comply, or face blocking by Russian authorities. The provider declined to comply with the request and shut down its Russian servers on April 1. In September 2019, NordVPN announced NordVPN Teams, a VPN solution aimed at small and medium businesses, remote teams, and freelancers who need secure access to work resources. Two years later, NordVPN Teams rebranded as NordLayer and moved toward SASE business solutions. On October 29, 2019, NordVPN announced additional audits and a public bug bounty program. The bug bounty was launched in December 2019, offering researchers monetary rewards for reporting critical flaws in the service. In December 2019, NordVPN became one of the five founding members of the newly formed VPN Trust Initiative, promising to promote online security as well as more self-regulation and transparency in the industry. In 2020, the initiative announced five key areas of focus: security, privacy, advertising practices, disclosure and transparency, and social responsibility. In August 2020, Troy Hunt, an Australian web security expert and founder of Have I Been Pwned?, announced a partnership with NordVPN as a strategic advisor. In 2022, NordVPN closed its physical servers in India in response to the CERT-In's order for VPN companies to store consumers' personal data for a period of five years. In April 2022, NordVPN's parent company Nord Security raised $100 million in a round of funding led by Novator. The company's valuation reached $1.6 billion. In September 2023, the company grew and raised more funding, making it valued at $3 billion. In 2022, Surfshark and Nord Security merged under one holding company. In July 2024, at the request of Roskomnadzor, Apple removed NordVPN from the Russian App Store. The company later confirmed that it had fully exited the Russian market. As of 2026, Nord Security reported having over 20 million users across its products, while NordVPN accounted for approximately 15 million users.

Technology NordVPN has desktop applications for Windows, macOS, and Linux, as well as mobile apps for Android, iOS and Android TV app. Subscribers also get access to encrypted proxy extensions for Chrome, Edge and Firefox browsers. Subscribers can connect up to six devices simultaneously. NordVPN has released its Linux client under the terms of the GPLv3 only. In November 2018, NordVPN claimed that its no-log policy was verified through an audit by PricewaterhouseCoopers AG. In 2021, NordVPN completed an application security audit, carried out by a security research group VerSprite. VerSprite performed penetration testing and, according to the company, found no critical vulnerabilities. One flaw and a few bugs that were found in the audit have since been patched. In October 2020, NordVPN started rolling out its first colocated servers in Finland to secure the hardware perimeter. The RAM-based servers are fully owned and operated by NordVPN in an attempt to keep full control. In December 2020, NordVPN initiated a network-wide rollout of 10 Gbit/s servers, upgrading from the earlier 1 Gbit/s standard. The company's servers in Amsterdam and Tokyo were the first to support 10 Gbit/s, and by December 21, 2020, over 20% of the company's network had been upgraded. In January 2022, NordVPN released an open-source VPN speed testing tool, available for download from GitHub. In late 2023, NordVPN unveiled a dedicated app for tvOS immediately after Apple started supporting third-party VPN applications with the release of tvOS 17. Soon after, at the beginning of March 2024, NordVPN announced virtual server support in 50 new locations where physical servers were limited. In September 2024, NordVPN launched post-quantum encryption support for its Linux app.

Anti-malware tools In February 2022, NordVPN introduced an antivirus functionality available as part of the regular VPN license. The opt-in Threat Protection feature blocks web trackers, warns users about malicious websites, and blocks downloaded files that contain malware. As of March 2022, the feature is available on the Windows and macOS apps and works without connecting to a VPN server.

Worked examples

Example 1 — a first encounter with NordVPN

Start with the simplest possible case. Write down what NordVPN claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to NordVPN before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about NordVPN ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of NordVPN

In research: NordVPN appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses NordVPN in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: NordVPN is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2012 establishments in Lithuania, 2022 mergers and acquisitions, Internet privacy software, so understanding it makes those chapters shorter.
In everyday life: Look for NordVPN outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
