Using the Control Center

For a quick disconnect, you can toggle VPN in the Control Center:

Open the Control Center by swiping down from the top right corner (iPhone X or newer) or swiping up from the bottom (iPhone 8 or older).
Look for the VPN icon, which looks like a key or chain link.
Tap the icon to disconnect. If the icon isn’t visible, add it in Settings > Control Center > Customize Controls.
Once tapped, the VPN disconnects immediately, and the icon will disappear or change to an unconnected state.

This is a convenient method for quick toggling while on the go.

Disconnect via the VPN App

If you’re using a third-party VPN app, most allow you to disconnect directly within the app:

Open the VPN app installed on your device.
Tap the button labeled Disconnect or Stop.
This will terminate your VPN session.
Some apps provide quick toggles in the widget or notification center for faster access.

Ensure the VPN app is updated for the latest features and security patches.

Additional Tips

If your VPN reconnects automatically, check the app’s settings and disable auto-connect features.
Always disconnect your VPN when not in use to avoid unnecessary encryption and data processing.
If you have trouble disconnecting, restarting your iPhone can reset network settings and resolve stuck sessions.

Using Screen Time Restrictions to Block VPN Apps

You can prevent access to VPN apps by setting restrictions via Screen Time, which is especially useful for parents, teachers, or anyone managing device use. This feature restricts the ability to open or install certain apps, including VPNs, and is simple to configure.

Open Settings and tap on Screen Time. If it’s not enabled, tap Turn On Screen Time and follow the prompts to set it up.
Tap Content & Privacy Restrictions and create or enter a Screen Time passcode. Keep this passcode secure.
Turn on Content & Privacy Restrictions.
Tap Allowed Apps. Here, you can disable access to VPN-related apps if they appear. Note that some VPNs may not be listed individually.
Return to Content & Privacy Restrictions and select iTunes & App Store Purchases. Set Installing Apps and Deleting Apps to Don’t Allow.
You can also restrict web content under Content Restrictions. For example, limit web access or add specific VPN websites to the blocked list.
Review and exit Settings. These restrictions will now limit app installation and usage, preventing unauthorized VPN app use.

While Screen Time restrictions are effective, tech-savvy users may find ways around them. Regularly reviewing and updating these settings enhances control over VPN app access on your device.

Removing VPN Configuration Settings

If you no longer need a VPN profile or want to troubleshoot connectivity issues, removing VPN configuration profiles is an effective solution. Deleting these profiles stops any automatic VPN connection and clears configuration data, improving security and freeing device storage.

Open the Settings app.
Scroll to General and tap.
Select VPN & Device Management. Depending on your iOS version, this may just be VPN.
In the list of configured VPN profiles, tap on the profile you want to delete.
Tap the Delete Profile button, then confirm by tapping Delete again if prompted.
Back in VPN settings, ensure the profile is no longer active or visible.

If your device is managed via an MDM profile, you might need to contact your administrator or remove the profile within Profiles & Device Management. Note that removing MDM profiles can impact device policies and security.

After deleting profiles, restarting your iPhone can ensure all changes are applied. Verify that the VPN icon is gone from the status bar and test your connection. If issues persist, resetting network settings can help, but this will erase Wi-Fi passwords and network preferences. To do this, go to Settings > General > Reset > Reset Network Settings.

Removing VPN profiles is a straightforward way to troubleshoot or disable VPN access on your device, helping to maintain control over network connections and security.

Blocking VPN via Network Settings and Router

If you want to prevent VPN usage across your entire network, configuring your Wi-Fi router or network infrastructure is effective. This approach enforces restrictions at the source, making it harder for users to bypass policies. Here are steps and tips for blocking VPN traffic at the network level:

Access your router’s admin panel. Open a web browser and enter your router’s IP address, typically 192.168.1.1 or 192.168.0.1. Log in using your admin credentials. If unsure, consult your router’s manual or look for a sticker on the device.
Locate the firewall or security settings. Within the admin panel, find sections such as “Firewall,” “Security,” or “Access Control.”
Create rules to block common VPN protocols. Many VPNs use protocols like PPTP (port 1723), L2TP, or OpenVPN (UDP 1194 or TCP 443). Setting firewall rules to block these ports can prevent VPN traffic.
Implement URL or domain filtering. Some routers allow blocking access to known VPN server domains. Adding these to a blacklist can restrict users from connecting to VPN providers. Note that VPN providers often change domains, so this method isn’t foolproof.
Use IP address blocking. For advanced control, identify and block IP ranges used by many VPN servers. Keep in mind that VPN IPs often change, requiring ongoing updates.
Enable QoS or traffic management. Configure Quality of Service (QoS) settings to prioritize or restrict VPN traffic, thus limiting unauthorized usage.
Test your restrictions. After applying rules, attempt to connect to a VPN to validate the restrictions are effective.

Tech-savvy users might still find ways to bypass these blocks, using different protocols or stealth VPNs. Regularly updating your router’s firmware and security policies enhances your control. Combining router-level blocking with network monitoring provides a comprehensive security strategy.

Tips for Preventing Unauthorized VPN Usage

To keep your network secure and prevent unauthorized VPN use, consider these best practices:

Develop a Clear VPN Policy

Create written guidelines explaining who can use VPNs, approved providers, and proper usage rules. Ensure users understand consequences for violations. Regularly review and update the policy to address new threats.
Restrict VPN Access with Authentication

Use strong authentication methods like multi-factor authentication (MFA) for VPN login. Require unique credentials for each user and avoid shared accounts. This helps restrict access to authorized personnel only.
Monitor VPN Traffic Actively

Implement network monitoring tools to detect VPN activity. Look for unusual patterns such as frequent connections or access from unexpected locations. Log and investigate suspicious activity promptly.
Block Unauthorized Protocols and Ports

Configure your firewalls to block common VPN protocols if they’re not authorized. Limit VPN connections to specific ports to prevent users from using unapproved services.
