How to Use a VPN Correctly: Complete Recommendations for Security, Speed, and Privacy

To use a VPN effectively, choose a service with a strict no-logs policy and a modern protocol (e.g., KelVPN), connect to the VPN before logging into any accounts, enable the Kill Switch, regularly test for IP/DNS leaks, and never rely on free VPNs for sensitive tasks. The optimal strategy is to keep your VPN on at all times on all devices, especially when using public networks.

1. How to Choose a Reliable VPN Service

Choosing a VPN is the first and most important step. Not all VPNs are equally secure, and a mistake at this stage can undermine all your privacy efforts.

Key selection criteria:

Zero-logs policy: The service must not store connection history, IP addresses, timestamps, or traffic volume. KelVPN has a strict zero-logs policy reinforced by its decentralized architecture.
Modern protocol and encryption: The KelVPN protocol delivers high speed and quantum-resistant encryption.
Decentralized architecture: No single central server increases resistance to blocking and attacks. KelVPN uses a network of independent nodes.
Kill Switch feature: An emergency internet cut-off prevents data leaks when the VPN drops. KelVPN’s Kill Switch is always on.
Jurisdiction: Prefer countries with strong privacy laws (e.g., Switzerland, Iceland). KelVPN operates in a decentralized jurisdiction with no single regulator.
Transparency and audits: Services that have undergone independent security audits are more trustworthy.
Reputation and reviews: Read independent reviews and ratings on technical forums and security sites.

Avoid free VPNs for sensitive operations. Free services often cover their costs by collecting and selling user data, displaying ads, or injecting malware.

2. Setting Up Your VPN: Step-by-Step Recommendations

Proper configuration is as important as choosing the right service. Even the most secure VPN can leak if misconfigured.

Step-by-step setup for KelVPN:

Download and install the app from the official KelVPN website (avoid third-party sources).
Purchase an access key (cryptocurrency or bank card).
Launch the app and verify that the Kill Switch is active (in KelVPN it is always on and cannot be disabled).
Select the protocol. The KelVPN protocol is recommended (default).
In the “Advanced” section, enable DNS leak protection and IPv6 leak protection (built into KelVPN).
Configure auto-connect on system startup if you plan to use the VPN constantly.
If needed, set up split tunneling to allow specific apps to bypass the VPN.

After configuration, always run leak tests (see section 4).

3. Daily Habits for Safe VPN Usage

Even with a properly configured VPN, certain practices increase or decrease your security level.

Do’s (recommendations):

Keep the VPN on at all times, not only for “important” activities. Data leaks can happen at any moment.
Connect to the VPN before opening any browser or app that handles personal data (email, banking).
Use the VPN on all devices: laptop, smartphone, tablet. One KelVPN key works on an unlimited number of devices.
Regularly update your VPN client to the latest version.
Always turn on the VPN before using public Wi-Fi.
Use two-factor authentication (2FA) on all important services in addition to the VPN.
Periodically check for leaks (e.g., at ipleak.net) while the VPN is active.

Don’ts (anti-recommendations):

Do not disable the Kill Switch unless absolutely necessary. In KelVPN it cannot be disabled — that is by design.
Do not use free VPNs for banking or email.
Do not ignore browser warnings about invalid certificates, even when the VPN is on.
Do not switch VPN servers too often within a single session — it may raise suspicion from websites.
Do not install unknown certificates offered by some VPNs (this could be a MITM attack).

4. How to Test Your VPN for Leaks and Correct Operation

Regular testing ensures your VPN works exactly as expected.

Test type	Tool / website	Expected result
IP address check	ipleak.net, whatismyip.com	IP must match the country of the selected VPN server, not your real IP.
DNS leak test	ipleak.net (extended test), dnsleaktest.com	Should show VPN DNS servers, not your ISP’s.
WebRTC leak test	browserleaks.com/webrtc, ipleak.net	Your real local or public IP should not appear.
IPv6 leak test	ipleak.net, test-ipv6.com	If your ISP uses IPv6 and the VPN does not block it, a leak may occur. KelVPN blocks IPv6.
Kill Switch test	Manual: disconnect the VPN (or simulate a drop), check internet access	Internet must be completely blocked when the VPN drops (always true for KelVPN).

Run these tests after initial setup, after VPN client updates, or when changing network environments.

5. How to Boost VPN Speed: Practical Tips

A VPN may slightly reduce speed due to encryption and routing, but you can minimize the impact.

Choose the nearest server. Shorter distance = lower ping and higher speed. KelVPN allows manual or automatic server selection.
Use a modern protocol. The KelVPN protocol is optimized for speed.
Switch servers if one is overloaded. Some nodes may be busier than others. Try another server in the same country.
Use a wired connection instead of Wi-Fi. Wired is more stable and faster.
Close background apps that consume bandwidth. Torrents, updates, and cloud syncs can clog your line.
If your ISP throttles certain traffic, a VPN can bypass throttling and may even increase speed. Test speed with and without the VPN.

Typical speed loss with KelVPN is 5–15%, which is unnoticeable for most tasks (web browsing, video streaming, video calls).

6. Special Recommendations for Different Scenarios

Depending on why you use a VPN, priorities may shift.

For public networks (cafés, airports, hotels):

Always turn on the VPN before connecting to the network.
Ensure the Kill Switch is active (guaranteed in KelVPN).
Do not disconnect the VPN until you have closed all apps containing personal data.

For bypassing geo-blocks (streaming, social media):

Choose a server in the country where the content is available.
Note that some services (e.g., Netflix) actively block known VPN IP addresses. Decentralized VPNs with clean IPs (like KelVPN) have a better chance.
When switching servers, clear browser cookies or use incognito mode.

For torrents and P2P:

Use a VPN that allows P2P (KelVPN supports it).
Make sure Kill Switch is enabled so your real IP does not leak into the torrent network if the VPN drops.
Bind your torrent client to the VPN network adapter if possible.

For crypto exchanges:

Do not switch VPN servers too often to avoid raising suspicion from the exchange.
If possible, use a dedicated IP from the VPN provider.
Enable two-factor authentication on the exchange.

7. What Not to Expect from a VPN: Reasonable Boundaries

A VPN is a powerful tool, but not a silver bullet. It is essential to understand its limitations.

A VPN does not make you completely anonymous. Websites identify you via cookies, browser fingerprints, and login data.
A VPN does not protect against phishing or malware. If you voluntarily enter your password on a fake site, the VPN is useless.
A VPN does not protect against server-side breaches. If a website is hacked, your data can be stolen regardless of the VPN.
A VPN does not solve weak password problems. Use password managers and 2FA.
Free VPNs are often dangerous. They may collect and sell your data.

Use a VPN as part of a comprehensive security strategy, not as your sole defense.

8. Frequently Asked Questions About VPN Usage Recommendations

Should I keep the VPN on all the time? ▼

Yes, this is a best practice. Continuous VPN use protects against accidental leaks and ISP surveillance. Exceptions are situations where the VPN interferes with local services (you can use split tunneling).

How often should I change my VPN server? ▼

Only change servers when necessary: to access content from another country, when speed is low, or if the current IP is blocked. Frequent changes within one session may raise suspicion from websites.

Can I use a VPN on my router? ▼

Yes, if your router supports a VPN client (or firmware like OpenWRT). This protects all devices on your home network, including those that cannot run a VPN client (Smart TV, game consoles).

What if my VPN slows down the internet too much? ▼

Try switching to a closer server, change to a faster protocol (KelVPN uses an optimized protocol), and compare speed with and without the VPN. If the issue persists, contact support.

How can I verify that a VPN truly keeps no logs? ▼

Choose services that have undergone independent security audits (e.g., by Cure53 or other well-known firms). KelVPN does not store logs for architectural reasons — a decentralized network has no central point for log collection.

Should I use a free VPN for testing? ▼

For testing technical aspects, you can, but do not enter personal data. For regular use and sensitive operations, choose a reliable paid VPN.
