GhostPort vs Firewalla — Which Privacy Router Is Right for You?

If you're shopping for a privacy-focused router in 2026, two names keep coming up: GhostPort and Firewalla. Both aim to put you back in control of your home network. Both block ads and trackers. Both offer VPN capabilities.

But they take fundamentally different approaches to get there. This is an honest comparison — we'll tell you where Firewalla wins, too.

What Is Firewalla?

Firewalla makes a line of security appliances ranging from the compact Firewalla Purple ($399) to the enterprise-grade Firewalla Gold Pro ($899). They sit on your network and provide firewall rules, intrusion detection (IDS/IPS), VPN server capabilities, and basic DNS-level ad blocking.

Firewalla's mobile app is genuinely excellent — polished, responsive, and packed with real-time network visibility. Their intrusion detection system is mature and well-tested. If you want a plug-and-play security appliance with a premium app experience, Firewalla delivers.

Credit where it's due: Firewalla has been doing network security hardware longer than almost anyone in the consumer space.

What Is GhostPort?

GhostPort is a privacy router built on the Raspberry Pi 5. It runs GhostPort Phantom OS — a fully open-source operating system with Pi-hole for DNS-level ad and tracker blocking, WireGuard VPN tunneling, four distinct privacy modes, a browser-based Command Deck dashboard, and a full Linux desktop. It ships in three kit tiers from DIY to fully assembled.

GhostPort was designed from scratch around one question: what would a router look like if privacy was the entire point?

Feature Comparison

Where Firewalla Wins

Let's be straight about it:

The app. Firewalla's mobile app is one of the best in any networking product, period. Real-time flow monitoring, per-device controls, intuitive rule creation. GhostPort's Command Deck is powerful but browser-based — it doesn't match Firewalla's native app polish yet.

Intrusion detection. Firewalla's IDS/IPS is battle-tested and mature. It actively monitors for suspicious traffic patterns, port scans, and known attack signatures. GhostPort focuses on privacy at the DNS and VPN layer rather than active intrusion prevention.

Plug-and-play simplicity. Firewalla is designed to work the moment you plug it in. No assembly, no configuration decisions. For someone who wants security without touching a terminal, that matters.

Where GhostPort Wins

Open source. This is the big one. GhostPort Phantom OS is fully open — you can audit every line of code running on your privacy router. Firewalla's firmware is closed source. You're trusting their word that nothing you wouldn't approve of is happening on the device. For a product that sits between your entire home network and the internet, that's a meaningful difference.

Real ad blocking. GhostPort ships with Pi-hole — the gold standard for network-wide ad and tracker blocking. Firewalla uses a simpler DNS-based filtering system. Pi-hole gives you granular control over blocklists, whitelisting, query logging, and per-client statistics that Firewalla's built-in filtering can't match.

Privacy modes. GhostPort offers four distinct privacy modes you can switch between from the Command Deck: standard browsing, enhanced privacy, DoubleHop VPN tunneling, and Z-HOP for maximum anonymity. Firewalla gives you VPN, but not a graduated privacy model.

Desktop capability. Your GhostPort is also a full computer. Plug in a monitor, keyboard, and mouse and you have a secure Linux desktop. Firewalla is a single-purpose appliance.

Value. A GhostPort DIY kit starts around $120. Firewalla's comparable product (the Gold) runs $485. Even the fully assembled GhostPort with a custom chassis undercuts Firewalla's mid-range pricing.

The Transparency Question

Here's the question that keeps coming back: should a privacy device be closed source?

Firewalla is a good product run by what appears to be a good team. But their firmware is proprietary. You can't verify what it does with your network data. You can't audit the IDS rules. You can't confirm there's no telemetry.

GhostPort is built on the principle that privacy hardware should be verifiable. If you can't read the code, you're taking someone's word for it. And in 2026, taking someone's word for it is how we got into this mess.
