Different security methods are used to ensure secure smartphone experiences, such as secure online gateways, endpoint protection, email security, VPNs, and other security measures. Some smartphones are specifically designed to provide users with the highest level of security possible. As such there are many benefits to using a secure smartphone, namely, the users’ data is protected from unauthorized access and the many threats that can come with this. Furthermore, the need for data privacy and security necessitates using a safe smartphone. A secure smartphone safeguards users from losing crucial data to cybercriminals by wiping the data in the event the device is lost or stolen.
The following are some of the most secure smartphones in 2023.
- Bittium Tough Mobile 2 C
- Purism Librem 5
- Apple iPhone 12 pro Max
- Silent Circle Blackphone 2
- Sirin V3

However, to use that VPN client to secure data in transit, users need the Bittium Secure Suite software solution for Bittium Tough Mobile 2 C. Also, the smartphone is a fantastic device that is only available to government agencies and other authorized organizations.
The Bittium smart gadget has, however, received some criticism. Some users claim that the Bittium Tough Mobile 2 C is a regular phone with water, shock, and dust resistance that prioritizes security over all other features. Despite the premium specs, the smartphone met the security needs of users who value security over specifications. Another area of contention is the device’s price compared to competing smartphones with similar features.
2. Purism Librem 5

The Blackphone 2 is the second smartphone from Silent Circle, a Swiss firm specializing in encrypted mobile phones. The smartphone offers a completely private experience, including advanced security features, comprehensive permissions control, and encrypted voice, text, and video chat. Silent Phone provides top-of-the-line security and functionality to help secure a company’s data.
The Blackphone 2 features a 5.50-inch touchscreen display with a resolution of 1080×1920 pixels. The Qualcomm Snapdragon, 615 octa-core processor in the Silent Circle Blackphone 2, runs at 1.7GHz with 3GB of RAM. Silent OS 1.1 is installed on the Silent Circle Blackphone 2, powered by a non-removable 3060mAh battery.
The Silent Circle Blackphone 2 includes 32GB of internal storage that users can upgrade up to 128GB through a microSD card. The Silent Circle Blackphone 2 is 165.00 grams and measures 152.40 x 76.40 x 7.90mm in height, breadth, and thickness. Silent Phone 2 also allows for secure team collaboration, including secure conference calls and secure group messaging.
Users and corporate communication security are the focus of this secure smartphone. Silent Phone supports OpenID Connect (OIDC) and Active Directory Federation Services for single sign-on (ADFS). Silent Phone offered an extra layer of security by allowing users to control security with security words. This one-of-a-kind system serves as the “final line of protection” against man-in-the-middle attacks.
The Blackphone 2 has a price range of $700 to $1200. The Blackphone 2 is equivalent to any other Android phone except for the operating system. The smartphone’s Silent OS is a modified version of Android 5.1.1 Lollipop that adds a variety of new security capabilities to the device.
A security umbrella feature, which integrates a variety of granular controls without sacrificing the overall experience, is the key to the Blackphone 2’s success. Concerning users’ data, Silence Circle takes a “zero-knowledge” approach. Despite the security protections, the basic Android Phone and messaging apps are still available on the home screen, allowing users to make unencrypted phone calls or send text messages.
The amazing security offered by the Blackphone 2 is one of its major advantages. However, compared to other smartphones, this device has some drawbacks, such as performance lags. Also, encrypted calling and messaging requires an additional fee. Secondly, the lack of encrypted email and security certifications on the Blackphone 2 could create problems for some enterprises, particularly government agencies, to rely on the smartphone. Blackphone 2 also does not support fast charging and is not waterproof.
Users of this smartphone reported that, despite the 3GB RAM, they still encounter lags while browsing. Blackphone 2 may not compete with some of the leading secure smartphones due to the way the device trades performance for privacy.
K-iPhone is an unhackable encrypted smartphone. The calls made on this safe smartphone are encrypted and sent over the cellular data network. Users’ internet security and privacy are a top priority for K-iPhone and the KryptAll protects users’ data by codifying the audio of the call.

What are the Security Features of Secure Smartphones?
With updates and the necessity to resist any cyber threat, smartphones are becoming smarter and more secure. All internet users must use encrypted phones to safeguard data with technological advancements. As a result, certain security features are essential for all secure smartphones.
Facial recognition is a vital security feature used to verify the user’s identity and unlock the device. There should, however, always be a backup option for recovering information from the phone, especially if the software begins to malfunction. Users can activate this functionality by navigating to Settings – Lock Screen & Security – Face recognition on most smartphones, then turn on face recognition. The user must also set up app verification and other features. This facial characteristic looks impenetrable to intruders, but users can reinforce the approach by introducing an additional layer of security.
One of cybersecurity software’s most frequent security features is a kill switch. Most smartphones have a kill switch that allows the entire phone to be wiped in case the phone gets lost and is difficult to be found. Users can navigate the account and remotely reset the device to factory settings, wiping out all personal data. Although nothing can bring the users’ device back, the data is encrypted, so the kill switch is a strong security feature.
Voice detection is another security feature required for the encryption of mobile phones. This voice security feature is useful for individuals who require immediate access to specific confidential information. Users can also use Google Assistant to create a voice match profile, which will only respond to the user’s voice. There’s also an Unlock with Voice Match option, which allows users to unlock the device by merely saying, “Ok, Google.” Voice security can be enabled by navigating to Settings – Lock Screen & Security – Smart Lock. After that, users must verify a backup passcode to choose Voice Match. The user can then choose Access with Voice Match to have the assistant record the user’s real voice.
A security feature used to locate misplaced phones is a message on the lock screen. Certain features, such as the lost phone prompt, allow users to message the person who recovered the phone. Users can locate this function under Settings – Lock screen and security – Lock screen signature on most smartphones. The user can leave a backup phone number or email address activated when the phone is stolen or lost.
What are the Best Security Apps for Secure Smartphones?
The best security apps for secure smartphones are listed below.
