How can a VPN be made more secure?

Using stronger encryption protocols significantly enhances the security of a Virtual Private Network (VPN) by ensuring that the data transmitted over the network is protected from unauthorized access and interception. Encryption transforms readable data into an unreadable format, which can only be reverted to its original form using a specific key.

When a VPN employs robust encryption protocols, such as AES (Advanced Encryption Standard) with a key size of 256 bits, the data is much more challenging for attackers to decrypt, thereby providing a higher level of security. This is crucial in preventing eavesdropping and ensuring that sensitive information, such as personal data or corporate secrets, remains confidential during transmission over potentially insecure networks like public Wi-Fi.

In contrast, merely increasing internet speed does not improve the security of the VPN itself; it might enhance performance but does not address vulnerabilities. Similarly, limiting user access can improve security in certain contexts, such as minimizing the risk of unauthorized usage, but it is the encryption that fundamentally protects the data being transmitted. Allowing unrestricted access to all users would generally lower the security posture of the VPN by exposing the network to potential threats from malicious actors without proper user verification and controls.
