What an Open-Source Client and a Bug Bounty Actually Establish
Published client code and a bounty programme are real signals with narrow scope. Neither tells you anything about what the server side records.

How Websites Tell You Are Using a VPN
Address reputation, registration data and traffic patterns give it away. Why sites care, what they do about it, and why extra verification follows.

Why Server and Country Counts Tell You Nothing
An inventory number with no agreed definition. Virtual locations, rented capacity and load all break the comparison. What to ask a provider instead.

VPN Leaks and Kill Switches: When the Tunnel Isn't Carrying Everything
A connected VPN can still leak DNS queries, IPv6 traffic, or everything during a reconnect. What each leak is and how to check for it.
-
How Does a VPN Work?
Your device builds an encrypted tunnel to a server, which forwards your traffic onward. Every property of a VPN follows from that one arrangement.

What a RAM-Only Server Claim Does and Doesn't Guarantee
Diskless servers limit what survives a reboot or a seizure. They do not limit what the server sees while running, or what sits upstream of it.

What Data a VPN Must Hold to Function at All
Some data is unavoidable: your address while connected, the destinations you request, an account, a payment. Knowing the floor makes claims readable.

What Survives a Tunnel: Traffic Metadata
Encryption hides content, not shape. Packet timing, sizes and volume remain visible, and they reveal more than most people expect. What that implies.
-
What Happens in the First Second of a VPN Connection
Resolve the server, negotiate keys, create a virtual interface, rewrite the routing table. Several things can go wrong, and one of them leaks.

Can a VPN Hide What You Do on a Managed Network?
On a managed device, largely no — monitoring sits above the tunnel. And the policy question matters more than the technical one. What actually applies.

If Everything Is Already Encrypted, What Is a VPN For?
HTTPS protects content between you and each site. A VPN hides which sites you reach from the network. Two different problems, two different layers.
-
Where the Tunnel Begins: Threats a VPN Can Never See
A VPN encrypts traffic after it leaves your applications. Anything running on your device is inside the tunnel with you, and travels along unexamined.

What a VPN Actually Changes on Public Wi-Fi
The café network can already see which sites you reach, but not what you send. A VPN closes the metadata gap, not the password-stealing one.
