During a drive across the Prairies I used Guru VPN whenever I stopped at motels with open Wi‑Fi, and the app connected quickly each time and kept my email access private.
VPN Protocols: WireGuard® and GuruShadow™ in Guru VPN
A VPN protocol decides how your device and the VPN server build the encrypted tunnel. Guru VPN uses two modern protocols and picks the right one for your network automatically, so you get a fast, private connection in one tap.
WireGuard® for fast, efficient everyday connections
GuruShadow™, designed to look like regular web traffic on restrictive networks
ChaCha20 encryption for your traffic
Automatic protocol selection — nothing to configure

What are VPN protocols?
VPN protocols are the sets of rules a VPN app and server follow to connect, verify each other and move your data through an encrypted tunnel. The protocol determines how the connection is set up, which encryption protects it, how quickly it reconnects when your network changes and how easy the traffic is to recognise as VPN traffic.
That is why protocols affect speed, security, battery use and stability on mobile networks. Some older VPN tunneling protocols are still around for compatibility, but modern ones are leaner, faster and built on current cryptography. Because they define how your data is authenticated and encrypted in transit, they're often called VPN security protocols.
Automatic protocol selection: one tap, the right protocol
You don't need to know which protocol to pick. When you tap Connect, the Guru VPN app chooses the protocol that suits your current network.
Step 1Tap Connect
Start the VPN from the main screen of the app.
Step 2The app checks your network
Guru VPN looks at how your current network handles the connection.
Step 3Open network → WireGuard®
On most home, office and mobile networks you get WireGuard® for speed and efficiency.
Step 4Restrictive network → GuruShadow™
Where VPN traffic is filtered or blocked, the app can use GuruShadow™ to keep the connection going.
Your traffic is encrypted either way. The protocol only changes how the tunnel is built and how it appears to the network.
Why the VPN protocol matters
The protocol shapes almost everything you notice about a VPN connection.
Speed
Efficient protocols add less overhead, so pages load quickly and streams start without long waits.
Security
The protocol and its encryption decide how well your data is protected on public Wi‑Fi and other untrusted networks.
Stable mobile connections
Good protocols reconnect quickly when you move between Wi‑Fi and mobile data, so you're not left waiting.
Harder to block
Some networks filter recognisable VPN traffic. Protocols like GuruShadow™ are designed to look like ordinary web traffic.
Battery life
Lightweight protocols do less work in the background, which helps on phones and tablets.
Works across devices
Guru VPN uses the same protocols on Windows, macOS, iOS and Android, on up to 10 devices per subscription.
WireGuard®: fast, modern everyday protocol
Best for everyday browsing, streaming and gaming. WireGuard® is a modern, open-source VPN protocol with a compact codebase. It connects quickly, handles switching between Wi‑Fi and mobile data smoothly and uses ChaCha20 encryption.
- Fast connection setup and reconnects
- Lean design that is efficient on phone batteries
- Modern cryptography with ChaCha20
GuruShadow™: built for restrictive networks
GuruShadow™ is our proprietary protocol built on VLESS. It is designed to make VPN traffic look like regular web traffic, so it is harder for networks to detect and block the connection.
Please follow local laws and the rules of the network you use.
- Designed to blend in with ordinary web traffic
- Helps keep you connected where VPN traffic is filtered
- Encrypted connection protecting your data in transit
How to connect with the best protocol in 3 steps

VPN protocols comparison: different types, security and ports
Here is how the different VPN protocols compare, including the ones built into Guru VPN.
| Protocol | Speed | Security | Best for | Typical ports |
|---|---|---|---|---|
WireGuard® (in Guru VPN) | Very fast | Strong, modern cryptography (ChaCha20) | Everyday use, mobile, streaming | UDP (commonly 51820) |
GuruShadow™, VLESS-based (in Guru VPN) | Fast | Encrypted; designed to look like regular web traffic | Restrictive networks | Web traffic ports |
OpenVPN | Moderate | Strong when well configured | Wide compatibility, custom setups | UDP 1194 / TCP 443 |
IKEv2/IPsec | Fast | Strong | Mobile devices, built into many systems | UDP 500 and 4500 |
L2TP/IPsec | Slower | Acceptable; relies on IPsec for encryption | Legacy devices | UDP 1701, 500, 4500 |
PPTP | Fast | Outdated and insecure — avoid | Not recommended | TCP 1723 |
The ports shown are typical defaults; many services adjust them. Guru VPN uses WireGuard® and GuruShadow™.

What Customers Say
Millionsof satisfied users

average ratingTrustedworldwide
I started using Guru VPN to watch
lectures from a university portal that blocks some regions, and since switching to a suggested server the streams load quickly and stay smooth.
Cool app
After noticing my kids often connect to random Wi‑Fi at malls, I added Guru VPN to their phones and showed them the single connect button, and now they enable it before watching videos or using social apps in public places.
I love that I can set Guru VPN to
auto-connect on certain networks, so once configured, I don't have to think about it. It provides constant, silent protection in the background. I've never seen that feature before.
Buffer free
I use this app daily for streaming, and it never buffers. It's super fast, super secure, and I love that it doesn’t log anything. One tap and I’m fully protected! Couldn’t ask for more!
I installed Guru VPN to add an extra
layer of security when accessing corporate dashboards from home, and it now connects automatically before I log in to any work system or cloud service.
Simple use
The way this VPN works, I'd say it is perfect for everyday use! Whether I’m shopping online or watching geo-restricted media, Guru VPN keeps me anonymous and connected. Simple, trustworthy, and effective.
The best
On my daily train cọmmute I open Guru VPN, hit the single button, and read emails over the train Wi‑Fi knowing my connection is encrypted the entire ride.
I play competitive shooters where
every millisecond counts. This VPN's optimized servers actually improved my ping. I connect to a location closer to the game host, and my latency drops noticeably.
Must-have for remote work
As someone who works remotely, I rely on VPNGuru every day to secure my connection. It’s fast, stable, and I’ve never had an issue with dropped connections.
VPN protocols FAQ
The most common are WireGuard, OpenVPN, IKEv2/IPsec, L2TP/IPsec and the outdated PPTP. Some providers also build their own protocols for specific needs, such as Guru VPN's GuruShadow™ for restrictive networks.
There is no single winner for every situation, but secure protocols share three things: modern encryption such as ChaCha20 or AES, secure key exchange and server authentication, and a simple, well-reviewed design with fewer places for bugs to hide. WireGuard® was built with this in mind; protocols that miss these basics, like PPTP, are best avoided.
For most people, WireGuard® offers the best balance of speed, security and battery life. On networks that block VPN traffic, a protocol designed to look like regular web traffic, such as GuruShadow™, is often the better choice. Guru VPN switches between them automatically.
GuruShadow™ is Guru VPN's proprietary protocol based on VLESS. It is designed to make VPN traffic look like ordinary web traffic, which makes the connection harder to detect and block on restrictive networks. Please use it in line with local laws and network rules.
Guru VPN selects the protocol automatically so you can connect in one tap. The app picks WireGuard® or GuruShadow™ depending on your network, so you don't need to change any settings to get a good connection.
No. Guru VPN uses WireGuard® and GuruShadow™. We chose them because they are modern, efficient and cover both everyday use and restrictive networks.
No. PPTP is one of the oldest VPN protocols, and its security weaknesses are well known. It shouldn't be used to protect sensitive data, which is why modern VPN services, including Guru VPN, don't offer it.
The protocol is the overall method for building and managing the tunnel, while encryption is the cipher that scrambles your data inside it. Guru VPN protects your traffic with ChaCha20 encryption. Read more on our VPN encryption page.
Yes. Protocols differ in how much overhead they add and how quickly they connect and reconnect. Modern protocols like WireGuard® are designed to be lean, and Guru VPN servers support connections of up to 10 Gbps with unlimited bandwidth.
