On the App Store, you’ll find hundreds of VPN apps that promise to improve your online browsing experience. A VPN is a virtual private network, and when using an iPhone VPN service, you connect to the internet through a relay server. The app will encrypt your internet browsing, so you can stay private and anonymous no matter what you’re doing online.
But are VPNs actually safe to use on your iPhone? In this article, we outline why you must choose from the best VPN services for iPhone if you want your browsing to be truly secure and private.

Are iPhone VPNs secure?
VPN clients running on iPhone are as secure as the VPN protocols in use, and how well these protocols have been put into practice. VPNs can use anything from insecure Point-to-Point Tunneling Protocol (PPTP) to ultra-secure open-source OpenVPN, with AES 256-bit key encryption and 2048-bit RSA authentication.
On iPhones running iOS 8 or earlier, VPNs are more likely to use the Layer 2 Tunneling Protocol (L2TP), which is secure but slower than PPTP. Newer VPNs on iPhone often use Internet Key Exchange Version 2 (IKEv2), which is both fast and secure. One of IKEv2’s strengths is it’s quick to reconnect if you momentarily lose 3G/4G/LTE signal, making it perfect for on-the-road use.

What safety features should I look for?
Every VPN claims to offer privacy, but not all of them go into any detail. Look for what encryption the VPN uses. For example, ExpressVPN is a service that’s transparent about the technologies that it runs on. The company uses 4096-bit SHA-512 RSA certificates with AES-256-CBC and HMAC. You can check the VPN’s configuration files to confirm this.
ExpressVPN has DNS leak protection and runs its own 256-bit encrypted DNS servers. These servers are zero-knowledge, meaning that even the company itself can’t see what you’re accessing – plus the servers run only on RAM, which means vulnerable hard drives have been eliminated from the data chain.
You should also check the logging policy of the VPN service. Choose a VPN that doesn’t keep a log of connections, traffic, or IP addresses, so once you disconnect, there’s little to no trace that you ever used it.
What’s the best iPhone VPN?
In terms of security, privacy and auditing, a number of popular VPNs stand out. For example, NordVPN has recently undergone its second independent audit, and basic VPN provider TunnelBear prides itself on its regular audits. However, both of these lacks the configurability and versatility of our winner, ExpressVPN, which has been audited and also aced every test we put in front of it.
