Digital Security Solution is an independent publication focused on cellphone security, SIM swap attacks, and phone number protection.
Phone numbers are no longer just communication tools. They reset accounts, approve transactions, and act as recovery keys across the internet. Yet the systems designed to protect them were built for scale and convenience, not for resisting targeted abuse. This gap is where SIM swap and number-takeover attacks succeed.
We examine how these attacks work, why common defenses fail, and which controls meaningfully reduce risk. Our coverage focuses on mechanisms, failure paths, and real-world outcomes rather than marketing claims or feature lists.
Digital Security Solution evaluates carriers, VoIP services, and secure phone number providers using a threat-model-driven approach. Every option involves tradeoffs between usability and security, and we document those tradeoffs directly. No service is treated as secure by default.
This publication is written for readers who care about consequences, not reassurance. Our goal is clarity: understanding where mobile identity risk actually lives and what it takes to reduce it.
