However, this system has now been replaced by the Secure Terminal Equipment (STE) and SCIP standards which defines specifications for the design of equipment to secure both data and voice. The SCIP standard was developed by the NSA and the US DOD to derive more interoperability between secure communication equipment. A new family of standard secure phones has been developed based on Philip Zimmermann's VoIP encryption standard ZRTP. Called "Milcode", the phone was the first to implement code-excited linear prediction (or CELP) which dramatically improved voice quality and user-operability over previous LPC (Linear Predictive Coding) and LPC-10e versions. The base model offered a proprietary encryption algorithm with a key-length of 512 bits, and a more advanced model with a key-length of 1024 bits. Key exchange used a public key, based on Diffie-Hellman, as opposed to a plug-in datakey. A new key was generated for each phone call. The U.S. National Security Agency is developing a secure phone based on Google's Android called Fishbowl. In 1989 an Irish company called Intrepid developed one of the most advanced secure phones.

Mobile security is safeguarding computing resources and information in portable devices; this covers mobile phones, tablets, laptops, and wearable devices. The small size of these devices makes them very convenient when users are traveling or away from the office. Phishing — Messages attempting to get the user to reveal personal information such as login IDs or passwords. Mobile devices are communication hubs and can receive messages via email, text, phone calls, instant messages, etc. Mobile security is the practice of extending information security protections to portable computing devices. The very portability of phones, tablets, laptops, and other mobile devices means they are often outside the physical and network layer security measures put in place by an organization. Configuring the device to use a Virtual Private Network (VPN) whenever connecting via an unknown network decreases the threat of intercepted communications and data leakage. The VPN creates an encrypted connection between the device and a secure remote network. The number of mobile devices in use grows daily. It is important to include mobile and phone security as part of overall computer security for an organization.

There is no universally "most secure phone". Security depends on the threat, the operating system, update speed, configuration and user behaviour. For mainstream buyers, a current iPhone, Galaxy Enterprise Edition or Pixel is usually safer than an exotic device they cannot update or use correctly. Managed apps and work accounts can be removed without erasing the user's private material. The secure version of an iPhone is the updated, managed version with a strong passcode, phishing-resistant authentication and a clear recovery process. That display is a privacy aid, not a security boundary. Samsung says information can remain visible depending on viewing conditions. The meaningful strengths are long support, management and the ability to separate work data. ThinkPhone 25 targets ordinary enterprise requirements: zero-touch enrolment, remote management, firmware control and protection for lost devices. Motorola states five years of software support and security maintenance into 2029.
