Since the **Covid-19** crisis, remote work has become common in France. Employees now often work from home, coworking spaces, by swimming pools, or even in airports abroad. This flexibility has raised concerns about internet security, as data leaks, phishing attacks, and other cyber threats have become more prevalent. A **VPN**, or virtual private network, is often recommended for those who handle sensitive information or travel frequently. While data protection is the main focus, **VPNs** also offer additional benefits for those working remotely. When selecting a **VPN** for remote work, free options are generally not advised. These often have limited performance, poor security, and lack important features such as the **Kill Switch**, which automatically blocks internet access if the **VPN** connection drops. Some free **VPNs** may even collect personal data through targeted ads or act as **Trojans**, spreading malicious software. Instead, paid services from trusted providers are recommended. These offer stronger security features, such as **WireGuard** or **IKEv2** protocols, **AES 256-bit encryption**, and a **Kill Switch**. The number of devices that can be protected with one account is also a key consideration. Several **VPN** providers are recommended for their strong security and additional cybersecurity tools. These include **CyberGhost VPN**, **VyprVPN**, **PureVPN**, and **IPVanish**. Some of these providers offer extra features such as password managers, antivirus software, encrypted cloud storage, and data leak detectors. For this guide, four providers stand out for their comprehensive range of tools: **NordVPN**, **ExpressVPN**, **ProtonVPN**, and **Surfshark**. Each has its own set of features, pricing, and device support. **NordVPN** is known for its heavy advertising and is often considered one of the best **VPNs** on the market. It offers a wide range of cybersecurity tools, including **AES 256-bit encryption**, **Kill Switch**, **Multi-Hop**, **Split Tunneling**, **Smart DNS**, **Dedicated IP**, and **Meshnet**. It can protect up to 10 devices and has servers in over 130 countries. For businesses, **NordLayer** and **NordStellar** are available, offering centralized control and digital vulnerability detection. **ExpressVPN** is also highly regarded, with strong performance and a strict privacy policy. However, its acquisition by **Kape Technologies**, a company previously linked to malware, has slightly affected its reputation. It supports up to eight devices per account and has servers in 105 countries. It uses protocols such as **OpenVPN**, **IKEv2**, and **Lightway**, and includes features like **AES 256-bit encryption**, **Kill Switch**, **Split Tunneling**, and **TrustedServer** technology. **ProtonVPN** is focused on privacy and was created by scientists from **CERN** in Switzerland. It offers a free version with servers in 10 countries and a Pro version that includes services like **Proton Mail**, **Proton Pass**, **Proton Drive**, **Proton Docs**, and **Proton Calendar**. It uses protocols such as **WireGuard**, **OpenVPN**, **IKEv2**, and **Stealth**, and offers features like **Secure Core** and access to the **Tor network**. **Surfshark** allows an unlimited number of devices per account and includes features like a rotating IP, **Camouflage mode**, and a virtual identity generator. It uses protocols such as **OpenVPN**, **IKEv2**, and **WireGuard**, and offers features like **Kill Switch**, **Split Tunneling**, **AES 256-bit encryption**, and **Multi-Hop**. It is part of **Nord Security**, the parent company of **NordVPN**.
