Quick Summary!

Many people think device encryption is enough to prevent hackers from compromising their online security. Though this method is relatively safe, you still need to look for other reliable ways to guarantee the highest level of protection.

Apple markets iPhones as “walled gardens,”; a metaphor highlighting the security these devices offer. However, recent incidents and researchers have somewhat dented this image, proving how crucial it is to encrypt your iPhone. For example, in September last year, iPhone devices were subjected to the Israeli malware “Pegasus,” which exploited iPhones and other Apple devices via a “zero-click exploit.” 

However, encrypting only your iPhone is not enough. While it may prove helpful against spyware, malicious applications, or trojans, there is always the online surveillance that every user going online needs to worry about. In other words, it is also downright crucial to encrypt calls, messages, and other forms of communication to help bypass online surveillance and data collection issues. 

Fortunately, there are various fool-proof methods to encrypt your data, such as using a VPN or end-to-end encrypted apps for calls and messages that don’t log your data. But since choosing the best method can be tricky, this article explores all the options for you.

What makes encryption apps secure?

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 from the start. Lastly, the apps must refrain from collecting and sharing users’ data with any third party.

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 app for iPhone.

What is the best way to encrypt the data?

Using the best VPN provider is the most reliable and secure method for encrypting the data. Instead of providing partial encryption, a VPN completely encrypts the internet. A VPN encrypts everything, be it your messages, calls, photos, files, browsing history, emails, or search results. It encrypts and routes your internet traffic via an encrypted tunnel that prevents snooping eyes from knowing what you are doing on the web. It connects you to a remote VPN server that hides your IP address and ensures maximum anonymity while browsing the web. Therefore, use the best VPN provider and enjoy maximum encryption. 

What other benefits an iPhone user can enjoy by using a VPN for encryption?
