Question 1

What does TLS 1.3 encryption actually mean, and is it strong enough to protect my data from sophisticated attackers to ensure my personal data and browsing activity remain fully private?

Accepted Answer

TLS 1.3 uses modern cipher suites with 256-bit keys and mandatory forward secrecy. It is the same encryption standard used by banks and major websites, and is considered unbreakable by current technology.

Question 2

How does VPN encryption differ from the HTTPS encryption that already protects most websites I visit to ensure comprehensive protection of my personal information and online activity from potential threats?

Accepted Answer

HTTPS encrypts data between your browser and the website, but your ISP still sees which sites you visit (DNS queries). VPN encryption wraps all traffic — including DNS — in an additional encrypted layer, hiding everything from your ISP.

Question 3

Which VPN protocol should I choose in FreeGuard settings for the best combination of speed and security and what steps can I take to optimize my connection speed?

Accepted Answer

Use hysteria2 for the best speed on unrestricted networks. Switch to anytls or trojan if you need to bypass deep packet inspection or network censorship in restrictive environments.

Question 4

Does VPN encryption slow down my internet speed, and how much performance do I lose from the encryption overhead and what steps can I take to optimize my connection speed?

Accepted Answer

hysteria2's efficient QUIC-based design keeps overhead minimal — typically 5-10% speed reduction on nearby servers. Modern devices handle encryption without noticeable delay.

Question 5

Is my VPN encryption still protecting me if I connect to a public Wi-Fi network at a coffee shop or airport when I am using a VPN service?

Accepted Answer

Yes. This is one of the most important use cases. VPN encryption prevents anyone on the same Wi-Fi from intercepting your data, including login credentials, emails, and browsing activity.

Question 6

Can a government or intelligence agency with advanced resources break the TLS 1.3 encryption used by FreeGuard VPN and what are the most important things I should know about this?

Accepted Answer

No known technology can break TLS 1.3 encryption. The cipher suites used are considered secure against both classical and near-term quantum computing threats.

Question 7

What is perfect forward secrecy and how does it protect my encrypted VPN sessions from future compromise to ensure my personal data and browsing activity remain fully private?

Accepted Answer

PFS generates a unique key for each session. If a key is ever compromised, only that one session is affected. All previous and future sessions remain encrypted with different, unrelated keys.

Question 8

Does FreeGuard VPN encrypt all traffic from my device or only web browser traffic when I connect and what are the most important things I should know about this?

Accepted Answer

FreeGuard encrypts all internet traffic from your device — every app, every service, every background process. This includes DNS queries, streaming, gaming, and system updates.
