How VPNs work: tunnels, protocols and trust
Encryption, a detour through one server, and a question of who you trust.
The idea in three moves
A VPN does three things. It encrypts traffic on your device before it leaves. It sends all of it to one server instead of straight to the sites you use. And that server passes your requests on from its own address, then returns the replies the same way. The network in between, at home, at a stadium or in a hotel, sees only one encrypted connection to one place.
Ask in the bot. The same people who run the servers answer there.
Ask in the botProtocols you will run into
- OpenVPN is the veteran, built into many routers and business networks.
- WireGuard is newer and leaner, and many commercial apps now default to it.
- IKEv2 is the one built into the network settings of phones and computers.
- VLESS runs in clients such as Hiddify and v2rayNG, and is designed to look like ordinary HTTPS.
What the provider still sees
A tunnel moves trust rather than removing it. The FTC puts it this way: a VPN generally will not make you entirely anonymous, and you shift your reliance from the network to the VPN provider. The provider's server sees which sites you reach, though not the content of encrypted pages. A no-logs policy is a promise about what is stored, so it matters who makes it.
Softech VPN says it does not record what you watch or browse and does not keep connection times; what it stores is the key, its expiry, the Telegram ID that receives it and a payment confirmation without card details.
Why Softech VPN uses VLESS with Reality
All Softech VPN servers run VLESS over Reality. Reality takes the opening handshake of a real, ordinary website, so to a network your connection looks like a visit to that site, wrapped in TLS 1.3. Networks that block well-known VPN protocols, as some hotels, offices and campuses do, have nothing obvious to block.
What no VPN can do
No tunnel stops a phishing page from asking for your password, or a bad app from reading what it was allowed to read. Sites you sign in to still know your account, and apps with location access still see your GPS position. A VPN guards the road between your device and the server. What happens at either end is up to the device and to you.

Questions
How is a VPN different from a proxy?
A proxy forwards traffic for one app, often without encryption. A client in full-device mode encrypts everything the device sends.
Does the tunnel hide me from websites?
It hides your IP address. Accounts, cookies and anything you type still identify you.
Which protocol is the fastest?
On a nearby server, all modern ones are fast enough for 4K video. Distance matters more.
Can my provider tell I am using a VPN?
With most protocols, yes. VLESS with Reality is built to look like ordinary web traffic.
Is VLESS safe?
Its encryption is TLS 1.3, the same protocol many banking sites use.
Do I need to understand protocols to use a key?
No. The client handles the protocol; you paste the key and connect.
