1. Internet encryption apps

The personal data on the iPhones are encrypted by default. An encrypted iPhone means that your passwords and other sensitive information remain safe and out of the reach of hackers, even if your phone is lost or stolen. But what about the data that’s all over the internet? Thus, iPhone users need to encrypt the data everywhere, including the entire internet.

Using the best private browsers is a way to encrypt the internet traffic on the iPhone. They use on-site encryption to prevent online tracking, block cookies, and browser fingerprinting attempts to ensure an anonymous browsing experience on the web. Similarly, using the best private search engines to help keep your searches private is crucial.

However, there’s a loophole. Private search engines and browsers may hide your IP address, but ISPs can still track you. They use partial on-site HTTPS encryption that won’t wholly encrypt the data and makes you vulnerable to online spying and tracking.

Using a reliable VPN provider is the best solution to get maximum anonymity and encrypt the entire data traffic. The best to encrypt internet traffic includes:


It uses AES 256-bit encryption, a 4096-bit RSA key, and an SHA-512 authenticating key for data encryption. In addition, the VPN follows a verified no-log policy meaning it won’t log nor share your data with anyone.


It uses strong encryption and a range of security-boosting features like a kill switch, 2FA, and multi-hop to protect the data from all snooping eyes.


It utilizes top-notch AES-256-bit encryption and follows a no-log policy to safeguard internet traffic. Besides this, users can also benefit from its core security features like a kill switch and dedicated IP address feature.

Make sure to use the best and most compatible VPN apps for iPhone to enjoy the highest level of digital privacy.

3. Use encrypted email apps

Email providers, like mainstream browsers and search engines, might be shocked that they can risk your digital security and privacy on the iPhone. They can track and record sensitive information like your IP address, email contents, location, and other identifiable information. In addition, they also contain vulnerabilities that can leak your data to the government or other malicious actors.

Using the best-encrypted email providers can prevent this issue. These email providers use P2P and E2E encryption and offer a range of features that encrypt the data and ensure that your online communication remains private. The most popular encrypted email apps are as follows:

Which is the best encryption app for iPhone?

The internet market is full of encrypted apps, but not all of them are reliable to use. After much research, it’s possible to say that Signal is the best encryption software for iPhone. It’s an instant messaging and video calling app that uses its advanced protocol for encrypting online communications. Besides this, the app has been audited, proving that it doesn’t compromise users’ security and privacy.

However, as it’s not very popular among the users, not a wide group of people use it. WhatsApp is the best alternative to Signal. It utilizes Signal protocol and standard AES-256-bit encryption to protect messages and calls. Also, it offers various security-boosting features that enhance the user experience.

These apps will only encrypt your messages and calls. To avoid all the cyber threats by encrypting all the information available on your iPhone, we recommend using a top-notch VPN like NordVPN. A VPN like NordVPN offers AES 256-bit encryption and encrypts all traffic by routing through its encrypted tunnel. In addition, the VPN also offers a split tunneling feature, allowing you to encrypt the traffic of the platform you want.

How to use a VPN for encryption on iPhone?

Follow these steps to use a Virtual Private Network for encryption on your iPhone:

  • Subscribe to a robust VPN like NordVPN
  • Install the VPN application on your iOS device
  • Open the server list and connect to a VPN server
  • Once you connect to a server, the VPN will route your traffic through its encrypted tunnel, resulting in encrypting your data on your iPhone

Other benefits of using a VPN

The best iPhone VPN offers other incredible benefits like:

  • It masks the IP address by connecting you to a remote server, making you more anonymous and private on the web. 
  • It helps bypass ISP throttling and ensures you browse the web with the fastest connection speed. 
  • The ISPs or other snooping eyes won’t be able to track or monitor your online activities. 
  • Users can circumvent internet censorship and access the web freely by connecting to a remote VPN server.
  • By hiding the contents of the internet traffic, users can safely access the geo-blocked content and download torrents. 
  • For all these reasons, use a reliable VPN to secure your online security and privacy completely.


While you can find various encryption apps online, choosing the best one can be challenging. When selecting the best encryption app, do look for three essential factors. The apps must be open-source, so inspecting the codes is easy. Moreover, it should offer default end-to-end encryption so that encryption is done immediately. Lastly, the apps must refrain from collecting and sharing users’ data with any third party.
Using the best VPN provider like NordVPN is the most reliable and secure method for encrypting the data. Instead of providing partial encryption, a VPN completely encrypts the internet. It encrypts everything, including your messages, calls, photos, files, browsing history, emails, or search results. Therefore, use the best VPN provider and enjoy maximum encryption.
