Remote work is now the standard, not the exception. But it introduced a significant security problem: most remote workers connect from untrusted networks, often without realizing the risks. A VPN is not optional for anyone working from coffee shops, airports, hotels, or coworking spaces. This guide covers the real threats you face, why a VPN matters, and how to pick one that actually protects your work.
Why Remote Workers Need a VPN
Remote workers use networks they do not control. Coffee shop WiFi, airport lounges, hotels, coworking spaces, client offices. Each of these networks is a potential attack point. An attacker on the same network can intercept unencrypted traffic, steal login credentials, inject malware, or monitor the websites you visit. If you are handling company data, customer information, or confidential files, this is a serious liability. A VPN encrypts all traffic leaving your device before it ever touches the public network. From the coffee shop WiFi's perspective, they see only an encrypted tunnel. The traffic inside that tunnel is yours.
Security Risks Without a VPN on Public WiFi
Packet sniffing is the simplest attack. An attacker runs free tools like Wireshark on the same WiFi and watches the unencrypted traffic flowing past. Email passwords, chat messages, form submissions, API calls. If the traffic is not encrypted by an application (HTTPS, Signal, etc.), the attacker reads it. Most applications do use HTTPS now, which is good. But metadata still leaks: which servers you connect to, how much data you send, when you send it. An attacker can see you are logging into your company VPN, checking your bank balance, or visiting specific websites, even if they cannot read the contents.
Man-in-the-middle attacks are more sophisticated. An attacker creates a fake WiFi hotspot with a name similar to the real one ("Starbucks_Free" instead of "Starbucks"). Users connect to the fake network thinking it is legitimate. The attacker now sits between you and the internet, able to intercept all traffic. They can steal credentials, inject a fake login page, or redirect you to a malicious website. Once they have your login, they have access to your company systems.
DNS spoofing redirects your traffic by poisoning DNS lookups. You type gmail.com, but the attacker's DNS server returns the IP address of a fake Gmail server they control. You log in, believing you are on the real site. The attacker captures your credentials.
Malware distribution is a softer threat but equally damaging. An attacker on the same network can inject malware into downloads, or serve it through a compromised website. Without a VPN, you have no protection against these injections.
Best VPNs for Remote Workers
Not all VPNs are suitable for work. You need one that is fast, reliable, does not throttle bandwidth, and has strong encryption. You also need to trust the provider not to log your activity.
ProtonVPN is the top choice for remote workers who prioritize security. ProtonVPN is based in Switzerland, is audited by Cure53, and has a published no-logging policy. The paid plans include unlimited bandwidth, server selection across 60+ countries, and split tunneling (route some traffic through the VPN, other traffic directly). Split tunneling is crucial for remote work: your company's internal tools stay on your home network for speed, while your general browsing is encrypted. ProtonVPN also offers a dedicated IP option, useful if your work requires static IP whitelisting.
Surfshark is fast, affordable, and offers unlimited simultaneous connections. This is useful if you are working on multiple devices (laptop, phone, tablet). Surfshark also offers a feature called CleanWeb, which blocks ads, malware, and phishing sites at the VPN level. Their no-logging policy is audited. For team deployments, Surfshark offers a business plan with centralized billing and user management.
ExpressVPN is the most expensive but among the fastest. It is based in the British Virgin Islands and has a strict no-logging policy. For remote workers who need maximum speed on international calls, ExpressVPN consistently ranks high. The interface is straightforward, and customer support is responsive.
CyberGhost offers an entire category of optimized servers for remote work, including dedicated servers for teams. This is less common in the VPN market and useful if your company needs to whitelist a static IP. Pricing is competitive, and they offer a 45-day money-back guarantee, the longest in the industry.
NordVPN is a large provider with a global server network and solid speed. NordVPN offers obfuscated servers in countries with heavy VPN restrictions. If you work from a country with internet censorship, obfuscation masks the fact that you are using a VPN.
How to Set Up a VPN for Work
Choose a VPN that supports your devices. If you work on Windows, macOS, Linux, iPhone, and Android, make sure the VPN has apps for all of them. Many remote workers switch between devices throughout the day.
Download the VPN app from the official website, not an app store. This sounds paranoid, but fake VPN apps have been found in official app stores before. Going directly to the provider's website eliminates this risk.
Enable split tunneling. Configure your VPN so that traffic to your company's internal network (intranet, VPN gateway, shared drives) routes directly without going through the third-party VPN. This improves speed and reduces load on the VPN servers. Your general browsing (Gmail, news, social media) goes through the VPN. To set this up, note your company network's IP range (ask IT), then add it to the VPN app's split tunneling whitelist.
Use a strong, unique password for the VPN account. This should not be your work password, not a password you use elsewhere. A breached VPN account means an attacker can impersonate you on the VPN network.
Enable two-factor authentication on your VPN account if the provider offers it. This prevents an attacker from logging in even if they steal your password.
Configure the VPN to auto-connect when you join a public network. Most VPN apps offer this setting. Set it to auto-connect on any WiFi network other than your home network (since VPN at home is less critical). This prevents you from accidentally browsing without protection.
Keep the VPN app updated. Security updates are released regularly, and running an outdated version defeats the purpose.
Test your connection for leaks. Visit ipleak.net with the VPN off, note your real IP. Then enable the VPN and revisit the site. Your IP should be the VPN server's IP, not your real IP. DNS leaks are also common: if the site shows your real DNS server, your VPN is leaking DNS queries. Most modern VPN apps do not leak, but testing takes seconds.
Beyond the VPN
A VPN is part of a broader security practice, not a complete solution. You still need to use HTTPS (check the padlock icon), never click suspicious links, update your operating system and applications regularly, and use a password manager. If your company uses multi-factor authentication, use it. If they offer endpoint security (Crowdstrike, Sentinel, etc.), install it and keep it running.
Remote work is here to stay. A VPN removes a major category of risk when working from untrusted networks. It is not an expense, it is insurance.
