Peace of mind in your pocket

No matter where you go, your smartphone is under constant attack from criminals, corporations and foreign governments. Professionals around the world trust their Armadillo Phone to protect them. Communicate instantly using encrypted email, insant messaging and audio or video calling. Travel safely to over 150 countries with multiple passwords and advanced hacking protection. If you need mobile security, you need an Armadillo Phone.


Armadillo Phone is designed from the hardware up to be secure. Cameras, microphones and fingerprint scanners can be physically removed. If you're forced to surrender your Armadillo, you can reveal a decoy password to enter a decoy mode. Or a wipe password to erase everything. Our unique anti-theft beacon will shutdown your phone if it's stolen. Your access card prevents unauthorized use, even if attackers have your password. Anti-hacking protection neuters attacks that would compromise other phones. High-strength encryption prevents us from being able to read any of your messages. Lockscreen improvements mitigate shoulder-surfing. Our network is monitored by a team of professionals waiting to defend against hackers. Regular updates keep you patched against the latest vulnerabilities. We even pay outside security experts to audit Armadillo Phone and help uncover unknown flaws.


We value our customer's privacy and this is why we offer anonymous payment methods and require no personal information to purchase. We operate on a "zero-trust" basis, so we never have access to a user's messages or encryption keys. You can also purchase your own server to maintain total control of your metadata.

Protect yourself now


Tamper-resistant packaging

All our packaging and shipments are sent with tamper-evident seals to prevent your orders from being intercepted and physically modified. Package interdiction is a common method state-sponsored attackers use to compromise your security.

Device inspection

Devices are disassembled and inspected prior to being sent to make sure we haven't received any tampered, modified or faulty hardware.

Secure hardware

Cameras, microphones and fingerprint sensors can be removed to prevent compromise in the unlikely event your Armadillo Phone is hacked. We use a highly-audited commercial smartphone as the starting point of our platform, with security bounties of up to $350,000 for vulnerabilities.

Multiple passwords

Armadillo Phone uses multiple passwords to allow you to hide your secrets, even when you're forced to give them up. The encryption is also strengthened, making bruteforcing attacks extremely difficult.

Use your secret password to access your real data.
Use your decoy password to access your decoy data.
Use your wipe password to erase your data.

Zero-Day Protection

A stripped down operating system, combined with advanced memory protection and code sanitization make memory corruption vulnerabilities that affect other phones extremely difficult to exploit. We use memory-safe programming languages whenever possible to further prevent attacks.

Security Peripherals

Security peripherals combine with your Armadillo Phone to enhance physical security.

Anti-Theft Beacon: Prevent theft or forensic seizure by automatically shutting down when disconnected.
NFC Access Card: Authenticate for an additional level of protection.

Proactive defense

Armadillo Phone is engineered using advanced hacking protection to defend against unknown vulnerabilities.

Our applications also monitor suspicious activity, alert the user and prevent attacks before they happen.

RAM Sentinel: Monitor the temperature for cold-boot attacks and shutdown if too cold.
Theft Sentinel: Alarm and shutdown the phone if the anti-theft beacon is disconnected.


Use advanced features to communicate like video conferencing, self-destructing messages and group chats. Decentralized end-to-end encryption protects your data, so even if our server is hacked your conversations are still secure.

Chat: Secured using OMEMO encryption.
Email: Secured using PGP-N encryption.


Enhance your business productivity without compromising security.

Calendar: Offline calendar to plan events.
Clock: Set alarms and timers.
Contacts: Offline contact storage.
Downloads: Manage downloaded files
Notepad: Encrypted notepad to store your thoughts.
PDF Viewer: Open and view PDF files securely.


Don't allow unknown third-parties to control your data. Protect yourself with our included communications network or use your own. We can supply you with private servers completely under your control.

Who is Armadillo Phone

The rise of surveillance capitalism, cybercriminals, and state-sponsored attackers has hurt something we love, the Internet. We believe free and private democratic speech is the most powerful force on the earth. But without the security to confidently back that up, it's meaningless.

Armadillo Phone is the product of Pacific Research Alliance . PRA was founded in Vancouver and is proudly Canadian. Even though zero-trust encryption renders us incapable of revealing a user's data, we celebrate the fact that strong Canadian privacy laws protect our users around the world from unreasonable requests. Our team has been securing high-security decentralized communications since 2014, launching the original Armadillo Phone in 2016. We sponsor opensource protocols, including OMEMO (which we paid the cryptographic audit for) and a number of other projects.

Armadillo Phone is about real practical security, not gimmicks. We don't make false claims about an "unhackable" phone, because any phone can be hacked. We offer the next best thing: a phone designed to be attacked. Armadillo Phones have been deployed internationally and in high-risk scenarios. We offer high-quality customer support via encrypted communication, our website and in person. We're an honest company backed by real people ready to defend your digital privacy.
