Development update! Work is still coming along. A few modules are almost ready to launch. I'd say I'm 95% finished with PhantomVault and PhantomProtect, with PhantomWipe coming later. Check out my latest blog post, and sign up for updates to find out when we finally launch!

Progress on native FSKit Vaults, movie carriers, and PhantomProtect's launch validation.

Ever wonder what it takes to build a native macOS security app from scratch? 🛠️

We just published a deep dive into the creation of PhantomSecure over on the engineering blog! From relying on legacy tools like TrueCrypt in the Middle East to engineering a modern, privacy-first suite using Post-Quantum Encryption (PQX) and Apple's native Content Filter... it’s been quite the journey.

We’re keeping things 100% on-device and prioritizing your privacy because we believe Mac users deserve better than data-hungry corporate software.

What happens when a password isn’t enough to protect your sensitive files?

In our latest engineering blog post, we break down the critical difference between standard encryption and plausible deniability. We explore the anatomy of a "hidden vault" and why relying solely on standard protections might leave you vulnerable against targeted extraction.

Learn how PhantomVault for macOS 26 uses advanced cryptographic obfuscation, decoy passwords, and even fake metadata injection to ensure your data stays truly hidden—even under severe duress. 🛡️

Hello everyone, and welcome to PhantomSecure!

I'm excited to finally introduce this project after two years of development. PhantomSecure (by Little Guy Dev, LLC) is a dedicated macOS security app built from the ground up for macOS 26.

We've taken a privacy-first approach to keeping your system clean. Instead of routing your data externally, our PhantomProtect module acts as an intelligent on-device local network monitor to stop threats in real-time. We also offer tools like PhantomVault for Kyber-768 encrypted storage and PhantomWipe for secure file deletion.

We are actively developing new features, and you can check out our Roadmap page for upcoming additions like polymorphic malware protection.
