Further information about VPN security

Hello.

Some suspicious actions by malicious agents who have access to personal data, such as executives of internet service providers or individuals with advanced telecommunications expertise, compel me to seek your advanced knowledge on security issues related to VPN usage.

That's why I would like to ask the following questions.

• Are video calls via Viber or Whatsup protected by the VPN, preventing a malicious internet observer from collecting conversation data?
• Can an online attacker gain access the webcam or microphone when the computer is connected to the VPN?
• Can an attacker who gains access to a router extract data being transported via the VPN?
• Sometimes, certain websites or online procedures to government agencies, block access when a VPN is used. In this case, if a browser built-in VPN or extension VPN is used alongside Bitdefender VPN, the website will be unblocked. (This can also be happen with Youtube video viewing restrictions, without the user being logged in).
  The question is what security issues emerge for data transmitted via Bitdefender VPN and other browser VPN simultaneously. Is this combination safe?

Please enlighten me if this is possible with your knowledge of these important security issues.

Thank you.

Bitdefender VPN Security Quick Reference Guide:

Video Calls Protection:

A VPN encrypts all internet traffic, including Viber and WhatsApp calls. These apps already use end-to-end encryption, so the VPN adds an extra layer by hiding your IP address and preventing ISPs or malicious observers from tracking metadata.

Webcam and Microphone Security:

A VPN does not prevent malware or spyware from accessing your webcam or microphone. If attackers compromise your device, they can bypass VPN protection. Security here depends on antimalware software, system updates, and strict permission controls.

Router-Level Attacks:

Even if a router is compromised, VPN encryption prevents attackers from reading transmitted data. They may see traffic volume but not its content. Router malware, however, can attempt redirection or man-in-the-middle attacks. Keep router firmware updated and disable remote access.

Multiple VPN Usage:

Running a system VPN alongside a browser-based VPN or extension often causes routing conflicts, slower speeds, and potential leaks. Instead of double protection, this setup can weaken security. It is safer to rely on one trusted VPN provider and switch servers or temporarily disable VPN when accessing sites that block VPN traffic.

Key Recommendations:

• VPN protects against ISP surveillance and router-level snooping.
• It cannot protect against device-level malware.
• Avoid stacking multiple VPN.
• Keep your router secure and updated.
• Combine VPN use with strong antimalware protection like Bitdefender for maximum safety.
