The main benefits of using a VPN are better privacy on local networks, a different visible IP address, and safer connections on shared Wi-Fi. When you know what a VPN can and cannot do, you can use it more effectively. That’s why we listed 8 benefits of a reliable VPN app.
What does a VPN actually do?
When you connect to a VPN, your device creates an encrypted tunnel to a VPN server. Traffic covered by that tunnel passes through the VPN server before reaching its destination.
This provides two important functions.
1. People or organizations observing the local network generally cannot read the contents of properly encrypted VPN traffic.
2. Websites typically see the VPN server’s public IP address instead of your regular internet connection’s public IP address.
The Federal Trade Commission also notes that using a VPN shifts some trust from your local network or internet provider to the VPN company. This makes choosing a trustworthy provider important.
So, why use a VPN?
8 benefits you can get from using a VPN
1. Add protection when using public Wi-Fi
One of the most useful benefits of a VPN on public Wi-Fi is protecting traffic between your device and the VPN server. You also risk connecting to a fake network that looks similar to the legitimate hotspot. A properly configured VPN adds an encrypted layer to your connection.
This reduces the readable information someone monitoring the local network can obtain. CISA recommends VPNs or other authorized secure-access solutions for employees connecting through third-party networks.
HTTPS already protects most modern web traffic between your browser and the website. A VPN provides an additional encrypted connection from your device to the VPN server.
2. Improve privacy from your local network
One of the main privacy benefits of VPN technology is limiting what a local network or internet provider can directly observe about your traffic.
- Without a VPN, your internet provider handles your connection to online services.
- With a VPN, it primarily sees that you are communicating with a VPN server, along with information such as connection timing and the amount of data transferred.
Properly encrypted VPN traffic protects the contents between your device and the VPN server. This does not make your online activity anonymous. Websites can still recognize you when you sign in. Cookies, browser information, device characteristics, advertising technologies, and information you voluntarily provide can also identify or track you.
A VPN should therefore be seen as a privacy tool rather than a way to become invisible online.
3. Change the IP address websites see
Another common benefit of using a VPN is changing the public IP address presented to online services. After you connect, traffic routed through the VPN normally appears to come from the VPN server’s IP address.
Your home or mobile connection’s public IP isn’t presented to the destination in the same way. This can reduce the location information websites can estimate from your normal IP address.
It is important to understand the limitation. An IP address is only one way services identify users. Your account, cookies, GPS permissions, browser data, and other signals may still reveal information about you.
A VPN changes your network route. It does not create complete anonymity.
4. Protect remote work connections
Organizations can use VPN technology to provide employees with a protected connection to company networks and internal resources while working away from the office.
For example, a company may require employees to establish a VPN connection before accessing internal systems that are not exposed directly to the public internet.
NIST describes remote-access VPNs as connections between a remote user’s device and an organization’s VPN gateway.
This can be useful for:
- Remote employees
- Business travelers
- Freelancers accessing company systems
- IT administrators
- Teams working from multiple locations
Multi-factor authentication, updated devices, access controls, strong passwords, and endpoint protection remain important. NIST specifically recommends MFA alongside VPN access for remote business resources.
5. Add privacy when using a phone or tablet
The benefits of VPN on your phone are similar to those on a laptop. Phones move between networks throughout the day. You may use home Wi-Fi in the morning, mobile data during travel, and hotel or café Wi-Fi later.
A VPN can maintain an encrypted connection to its server across supported traffic. This can be particularly useful when you regularly connect to networks outside your control.
Still, installing a VPN app means trusting that provider with an important part of your network connection. Providers differ considerably in logging policies, security design, ownership, infrastructure, and data handling.
6. Support safer travel and remote connections
Hotels, airports, coworking spaces, and temporary accommodations often require you to use unfamiliar networks. A VPN can protect the connection between your device and its server while you work, browse, or communicate.
For business travelers, a company VPN may also provide access to resources that are designed for authorized employees rather than the public internet. Still verify the Wi-Fi network name before joining, keep your operating system updated, and don’t ignore browser security warnings.
7. Give you more control over network routing
Normally, traffic follows routes chosen by your internet provider and other networks between you and the destination. When you connect to a VPN, your traffic first goes to the selected VPN server. This can sometimes change connection performance.
In some situations, it may improve a poorly routed connection. It can also increase latency because the VPN server adds another point to the route. This matters most for gaming, video calls, and other real-time applications.
Quick note: Claims that a VPN always reduces ping, removes lag, or increases internet speed are inaccurate. Actual results depend on server distance, network congestion, routing, VPN protocol, device performance, and the provider’s infrastructure.
8. Protect traffic without changing every app
Another useful benefit of a VPN for personal use is that a full-device VPN can cover traffic from multiple supported applications at the network level. You don’t need to configure encryption separately for each app.
Modern VPN services may also provide features such as:
- Kill switch protection
- Split tunneling
- Automatic connection on selected networks
- Multiple VPN protocols
- DNS configuration options
These features vary by provider and device.
Split tunneling, for example, lets selected traffic use the VPN while other traffic uses the regular internet connection. A kill switch can restrict traffic if the VPN connection unexpectedly drops.
Can a VPN prevent ISP throttling?
A VPN encrypts traffic between your device and the VPN server. This can make it harder for an internet provider to classify certain traffic based on its contents or destination.
If an ISP’s traffic-management system depends on that information, using a VPN may change how it treats your traffic.
Quick note: A VPN cannot remove every form of throttling. It cannot overcome a data cap, network congestion, an overall speed restriction on your internet plan, or limitations further along the network. It can also reduce speed itself because encryption and additional routing require processing and network resources.
What are the limitations of a VPN?
Understanding the limits is as important as knowing the key benefits of VPN technology.
A VPN cannot:
- Guarantee complete anonymity
- Stop phishing websites
- Remove malware from your device
- Protect accounts with stolen passwords
- Stop every type of browser tracking
- Guarantee faster internet speeds
- Guarantee lower gaming latency
- Make every website trustworthy
The FTC also warns that VPN providers themselves may have different privacy practices. Users should check how a provider collects, stores, and shares information. Good online security still requires software updates, strong account security, MFA, careful browsing, and sensible privacy settings.
How to choose a VPN service
Look beyond marketing claims when selecting a provider.
- Step 1: Check which VPN protocols the provider supports.
- Step 2: Review the available server locations and network coverage.
- Step 3: Make sure the VPN supports your devices and operating systems.
- Step 4: Read the privacy policy and understand how the provider handles user data.
- Step 5: Avoid exaggerated claims such as “100% anonymous” or “completely untraceable.”
- Step 6: Compare speed, reliability, security features, and connection stability.
- Step 7: Check the quality of customer support and available help resources.
- Step 8: Choose an app that is simple to install, understand, and use.
- Step 9: Select a service based on your own privacy, security, and performance needs.
Final thoughts
The main benefits of a VPN come from encrypted network traffic, greater IP privacy, safer use of unfamiliar networks, and secure remote connectivity. At the same time, a VPN is only one part of online security. It does not prevent every cyber threat or make you anonymous. If you understand these limits and choose a reputable service, a VPN can be a useful addition to your everyday privacy and security setup.
