A VPN, short for Virtual Private Network, acts as a secure passage between your device and the vast realm of the internet. It's your digital shield against prying eyes, interference, and online restrictions. When connected to a trusted VPN server, your internet traffic is encrypted, ensuring a private journey that keeps hackers, government entities, and your internet service provider at bay.

How does a VPN work?
Connection Initiation
The VPN initiation process begins with your device establishing a secure connection to the VPN server. This involves the negotiation of a secure communication channel, typically employing protocols like IKEv2 or OpenVPN, ensuring a robust foundation for subsequent data transmission.
Authentication
Following connection initiation, user authentication takes place. This involves the verification of user credentials through methods such as username/password, digital certificates, or multi-factor authentication.
Data Encryption
Once authenticated, the VPN encrypts data using cryptographic algorithms like AES (Advanced Encryption Standard) or others, depending on the chosen encryption protocol. This ensures that the transmitted information is secure, private, and resistant to unauthorized access or tampering.
Transmission through Secure Tunnel
The encrypted data is then transmitted through a secure tunnel, commonly established using protocols like IPsec or TLS/SSL. This tunneling mechanism ensures data integrity and confidentiality, preventing interception or manipulation by malicious entities during transit.
Decryption at Server
Upon reaching the VPN server, the encrypted data undergoes decryption using the appropriate cryptographic keys. This process restores the original data, making it accessible for processing within the secure network. Advanced cryptographic mechanisms, including perfect forward secrecy, enhance the security of this stage.
Connection Termination
The final stage involves the termination of the secure connection. Proper termination protocols, such as IKEv2's DELETE message, ensure the graceful conclusion of the VPN session, freeing up resources and closing the secure channel between your device and the VPN server.

What does a VPN do?
VPN encryption protocols
Encryption protocols pave the way for strong connections, each with its own advantages—whether prioritizing speed, enhancing security, or adapting to specific network conditions—ensuring a customized and efficient VPN experience.
WireGuard is a modern and efficient VPN protocol known for its simplicity and high-performance capabilities. It operates with a smaller codebase, making it easy to audit for security, and its streamlined design results in faster connection speeds. WireGuard employs state-of-the-art cryptography, aiming to provide a secure and reliable VPN experience. Its efficient approach makes it an excellent choice for users seeking both speed and security in their VPN connections.
OpenVPN with User Datagram Protocol (UDP) is a widely-used VPN protocol valued for its speed and reliability. Unlike Transmission Control Protocol (TCP), UDP operates without establishing a connection, making it ideal for real-time applications such as streaming and online gaming. While UDP sacrifices some error-checking for speed, it is highly efficient for tasks where rapid data transmission is crucial. OpenVPN with UDP is a popular choice for users seeking a balance between speed and responsiveness in their VPN connections.

Frequently Asked Questions
Everything you need to know about VPNs and encryption protocols.
A VPN, or Virtual Private Network, is a cybersecurity tool that encrypts your internet connection, providing enhanced privacy and security. It's essential for safeguarding your online activities, protecting sensitive data from potential threats, and enabling secure access to the internet, especially on public networks.
Obfuscated servers employ advanced techniques to obfuscate or disguise VPN traffic, making it appear like regular HTTPS traffic. This involves encrypting the VPN metadata and encapsulating it within a layer of obfuscation, preventing deep packet inspection (DPI) systems from identifying and blocking VPN connections.
While obfuscated servers primarily focus on bypassing censorship, they also contribute to enhancing online privacy by encrypting VPN traffic. This encryption adds an extra layer of security, protecting your data from potential eavesdropping and ensuring a more private online experience.
Obfuscated servers may have a slight impact on internet speed due to the additional encryption and obfuscation processes. However, the trade-off between speed and enhanced privacy and access in censored regions makes obfuscated servers a valuable solution for some users.
While many modern VPNs use encryption to secure data, the initial connection or certain characteristics of the traffic might still be detectable. Also, some ISPs may block specific ports commonly associated with VPN traffic. Additionally, ISPs may employ traffic analysis to identify patterns and behaviors associated with VPN usage.
