Smartphones may not be as secure as you would like them to be. They are basically computers with radio antennae and can be as much of a risk as any desktop or laptop device to hackers or other snoopers.

If you want to buy a secure phone for better privacy and security, here are the five most secure phones you can buy.

1. Purism Librem 5

The Purism Librem 5 is designed with security in mind and has privacy protection by default. It uses PureOS, a free, ethical, and open-source operating system (OS) that is not based on Android or iOS. The phone doesn’t lock you into using this OS either — users can opt to install their own compatible GNU/Linux OS as an alternative. PureOS is based on the Debian OS.

It also has three hardware-based kill switches that disable the camera and microphone, switch off power from Wi-Fi and Bluetooth adapters, and stop all network connectivity, including GPS.

It sports a 3,500mAh removable battery, a 13MP primary camera, and 32GB of onboard storage. Users can expand the storage to 2TB via microSD

2. Apple iPhone 12 Pro Max

There is a lot to say about the Apple iPhone 12 Pro Max and its security. The latest iOS 14 operating system gives users more control over data and privacy with options to keep location, camera use, and access settings private. Protection is also built into its hardware and can encrypt all sensitive data.

It also comes with Face ID as a secure and convenient way to unlock your iPhone, authorize purchases and payments, and sign in to many third-party apps. Finally, “Find my iPhone” helps users find lost phones and prevents others from access and using a lost or stolen phone.

3. Blackphone 2

The Blackphone 2 uses Silent OS, an Android-based operating system enhanced to address mobile privacy concerns facing enterprises today. The vendors of the phone claim the devices come with no bloatware, hooks to carriers, or leaky data.

It also comes with a feature called  ”Spaces” that enables users to create multiple, separate "virtual phones" on a single device. This feature allows work and personal life to remain securely distinct as there is no data shared between the Spaces.

The phone has a 5.5-inch FHD+ display with Gorilla Glass protection and is powered by an octa-core Qualcomm Snapdragon processor. 

4. Bittium Tough Mobile 2C

The Bittium Tough Mobile 2C is a rugged and secure smartphone that boasts two operating systems for complete data separation. One OS is a hardened version of Android 9, and the other is the company’s Secure OS. Users can switch between the two with the device’s dual boot functionality.

It also comes with a free YubiKey 5 NFC security key to support two-factor authentication. There is also an always-on VPN and the company’s mobile device management software. 

The rugged phone has an IP67 rating and MIL-STD-810G, meaning it is waterproof to a degree and resists breakage.

5. Sirin V3

The Sirin V3 claims to use a multi-layered cyber security suite that includes a behavioral-based and machine learning Intrusion Prevention System (IPS) for proactive, real-time cyber protection. 

That aside, the device is based on Samsung’s latest business-class devices and has a Dual-Persona solution that incorporates two separated and protected zones. 

On the personal side, users can install apps from Google Play Store only for personal usage. A secured space is encrypted, and users cannot install new apps. It also sports a military-grade anonymous end-to-end encrypted call app.
