VPN security explained: Everything you need to know
Data is the backbone of your business. Data breaches can cost you more than money — they also can harm your growth and credibility.
At Proton, we can help you make your data more secure with our business VPN, which encrypts the data within your network.
Protect your organization’s most sensitive data, no matter the sector.
The basics: Why do I need a VPN?
What is a VPN?
A virtual private network (VPN) is a tool to protect your internet connection so that you and your workers remain private and secure online. We recommend using a VPN whenever you’re online on any device.
A VPN routes your internet traffic through a secure server that hides your real IP address and encrypts the data your device sends and receives.
How does a VPN work?
When you use a VPN, your device connects to a VPN server run by Proton VPN or another VPN service. The connection between your device and the VPN server is encrypted.
This means your internet service provider can’t see what you do on the internet, only that you’ve connected to a VPN server. It also means that anyone on the internet can’t see your real IP address, only that of the VPN server.
Why is it important?
A VPN prevents website owners, government agencies, hackers, advertisers, and your internet service provider from tracking where you are and what you do online.
How does a business VPN improve security?
Having a VPN will allow your business to:
Enable secure remote work
A VPN can help protect your remote workforce and ensure safe access to company resources from around the world, letting your team work securely from anywhere.
Simplify access control
A VPN can restrict logins for only approved devices and networks using private gateways. You can also assign and segment permissions so employees see only what they need.
Maintain compliance and confidentiality
A VPN allows you to secure sensitive information across your business's network, simplifying compliance with security frameworks like ISO 27001, SOC 2 type II, GDPR, and HIPAA.
Protect your data
A VPN uses strong encryption to protect your business's internet traffic on insecure public WiFi networks. A VPN will also stop your browsing data from being sold to advertisers. This also means that you can block ads.
Bypass restrictions and block surveillance
With a VPN, you can bypass censorship or other internet restrictions based on your geographical location, allowing you to access websites that might be blocked in your country. A VPN can also help thwart government surveillance.
Are VPNs secure?
A VPN is only as secure as the company that runs it. When choosing a VPN provider, you need to focus on trustworthiness. Your VPN provider handles your internet connection and can see the browsing history you’re trying to keep private, which means that choosing the right VPN provider is crucial. Here are the top questions you should ask:
- Is the VPN provider based in a country with strong privacy laws?
- Does the VPN provider have a strict no-logs policy?
- Is the VPN open source and independently audited?
At Proton, the answer is yes to all of these questions.
Protect your organization with Swiss-based privacy laws and a strict no-logs policy that prevents data retention and surveillance. Our strict no-logs policy means we don't track or store any information about your online activity. Transparency is at the core of our commitment to privacy. Like all our apps, Proton VPN is open source and independently audited. Anyone can look over our code to check our security claims.
Our top security features
At Proton, we have built a VPN that puts security and privacy at the forefront. Our features will protect your business's most valuable information:
Proton VPN encrypts all network traffic using either AES-256 or ChaCha20, both of which are extremely secure.
Proton's NetShield uses DNS filtering to block ads as well as the online trackers that advertisement companies use to follow you around the internet. This keeps your device secure and your browsing private.
Proton uses strong VPN protocols like WireGuard and OpenVPN. These protocols have a long track record of being secure, and we deploy these protocols at their highest encryption settings.
Proton's kill switch feature will immediately block your network traffic if your VPN connection is lost, preventing leaks.
Set up 2FA, SSO, and SCIM, enforce remote device management (MDM), and monitor authentication and connection events in real time within the easy-to-use admin panel.
Dedicated servers and IP addresses

Why Proton?
At Proton, we take a different approach from other VPNs. Instead of hiding information about our company, you can see exactly who we are, where we are, and what we stand for.
