Both BlackBerry and Apple prioritize security in their products. BlackBerry has a long history of providing secure communication for businesses and governments, and their devices and software are designed with security in mind. Apple's iPhone and iOS also have a strong focus on security and privacy, and they have implemented various features and technologies to protect user data. Ultimately, the level of security that a device provides can depend on a variety of factors, such as the specific device model and software version, as well as the user's own security practices. It would be best to consult experts and do research to determine which option would be best for your specific needs and requirements.
