GADNET - Next-Generation Security.

Just plug in to protect your home, family, and business.

75% of all observed IoT cyberattacks now target home and small-business routers — Zscaler ThreatLabz, 2025.

GADNET is a digital shield for your home and office, turning ordinary WiFi into a fortress. It protects your family and children from online threats and criminals. It's not just another router – it's an intelligent guardian that segments and isolates devices before threats reach your data. By default it assumes every device on your network could be compromised — that's what we mean by "Zero Trust": no implicit trust, every connection checked.

For specialists
GADNET integrates **NGFW** capabilities with a dedicated **internal PKI** to enforce a pure **Zero Trust** architecture. L3/L4 network segmentation with zone-based policy enforcement, dual-factor admin auth (mTLS device cert binding **or** WebAuthn AAL2 alt-path), and a Default Deny policy eliminate lateral movement. Hybrid TLS 1.3 with post-quantum KEMs (X25519MLKEM768, SecP256r1MLKEM768) is active by default; classical EC P-384/P-256 chain still serves admin.gadnet alongside a parallel ML-DSA-65 chain on admin-pq.gadnet.

Why Choose GADNET?

Zero Trust by Default

New devices land in isolation until you approve them. No more "anyone-on-WiFi sees everything".

Dual-Factor Admin Auth

Log in with a hardware key or fingerprint. Daily access goes through a device certificate; WebAuthn covers recovery and mobile.

GDPR by Design

Your data stays on the device. One-command export and erasure for any user — Articles 15 and 17 built in.

Streamlined Setup

Flash an SD card with balenaEtcher, plug in, and the captive portal opens automatically. ~15 minutes if you already have a FIDO2 key.

Open Source

Every line is public. No hidden telemetry, no obfuscation, no backdoors — and you can audit it yourself.

Supply Chain Transparency

Every release ships with a full ingredient list (SBOM) — like the label on a food product. Ready for the EU Cyber Resilience Act (Regulation 2024/2847, main obligations from 11 Dec 2027).

Protect Kids

DNS-level blocking for ads, malware, and adult content. Per-zone parental profiles you can age-tune.

Protect Business

Separate the work laptop, the point-of-sale terminal, and the IoT camera into different zones. A breach in one cannot jump to the others.

Internal Certificate Authority

GADNET issues its own certificates — for the admin panel, for each enrolled device, and for service-to-service mTLS. No external CA needed.

Quantum-Safe TLS

Tomorrow's quantum computers will be able to break today's encryption — but sessions encrypted with GADNET stay safe. Hybrid PQC is on by default.

Active Threat Monitoring

Rule-based port-scan detection, signature-based DNS filtering (UT1 lists + RPZ), and ML-based network-flow anomaly detection (IsolationForest). No vague "AI" claims — exactly what is and isn't machine-learned.

Universal Captive Portal

The setup page pops up on its own — iPhone, Android, Windows, macOS. The same way hotel WiFi greets you. RFC 8908 compliant.

Multi-Tier Backup

Your config is kept in four places: on the SD card, in a local snapshot, on a remote SSH server, and in S3. Cryptographically signed.

QR Code Onboarding

Scan a QR code with the new device — done. No fiddling with IP addresses, no copy-paste of long tokens.

Live Network Map

See every connected device, its zone, and what it's actually talking to. Real-time, not nightly snapshots.

Threat Dashboard

A single 0–100 score plus a feed of what triggered it. No security degree required to know whether something's wrong.

Transparent Update Path

Manual `apk upgrade` today, with Alpine LBU snapshots as a safety net. Auto-update daemon is on the roadmap for v1.0.

Localized Interface

Native English and Polish UI throughout — admin panel, captive portal, error messages. More languages welcome via community PRs.

Inside the admin panel — navigation skeleton

What's actually inside, grouped by purpose. The exact UI is still evolving in Phase B — these are the areas that ship today.

Tomorrow's quantum attack — blocked today

When sufficiently large quantum computers arrive, they will be able to break the encryption that protects today's internet. That means the data you send right now — passwords, conversations, banking, medical records — could be recorded by an attacker today and decrypted in 10–20 years, when that hardware arrives. GADNET uses new **quantum-resistant algorithms today**, side by side with the classical ones. Your sessions stay safe even if someone is recording them right now, waiting for tomorrow's hardware.

For specialists
Hybrid TLS 1.3 KEMs: X25519MLKEM768 (IANA codepoint 0x11ec) + SecP256r1MLKEM768 (0x11eb) per FIPS 203 ML-KEM-768. Active by default on admin.gadnet; group fallback to X25519 / secp384r1 / secp256r1 per RFC 8446 §4.2.8 if the client lacks PQC. Backed by OpenSSL 3.5+ and Python 3.14 stdlib ssl.SSLObject.group() telemetry (per-handshake hybrid_pqc audit field). Parallel ML-DSA-65 (FIPS 204) Root + Intermediate CA + server leaf on admin-pq.gadnet, opt-in via PQ_LISTENER_ENABLED until major browsers ship ML-DSA validators. ML-KEM-768 + hybrid HKDF substrate ready for Signal X3DH (Phase B).

Encrypted DNS — your queries no one can spy on

Every time you open a website, your device first looks up its address — a bit like flipping through a phone book. On most home networks that lookup is sent in the open: your internet provider, the coffee-shop WiFi, anyone sitting on the same network can read the full list of places your device looked up. GADNET seals every lookup inside an encrypted envelope by default, using three standards — DoH, DoT, and DoQ — depending on who is asking and where the answer has to travel. Nothing to switch on, nothing extra to pay for.

DoH — DNS-over-HTTPS

What it is: Wraps the lookup inside an ordinary HTTPS connection — the same kind your bank uses. To the rest of the network it looks like one more web request among many.

Example: Your laptop sends each DNS lookup to GADNET inside an HTTPS connection. Any other device on the same WiFi — a guest device, a misbehaving IoT gadget, a compromised smart speaker — just sees an encrypted connection to the router. The lookup names are invisible to them.

More details

Why it helps: DoH is the hardest of the three to identify and block at the network level. Networks that filter DoT (port 853) cannot easily do the same to DoH without breaking ordinary HTTPS browsing too.

Without it: Every name your device looks up is sent in plaintext on port 53. Anyone on the same network — a neighbour, a hotel admin, a captive portal — can keep a detailed log of everywhere your device looked, with timestamps.

DoT — DNS-over-TLS

What it is: A dedicated encrypted tunnel reserved just for DNS, on its own port. GADNET uses this tunnel to talk to trusted public resolvers — Cloudflare, Google, Quad9 — and checks their certificate against the expected hostname before sending a single query.

Example: When GADNET needs an address it does not already have cached, it asks Cloudflare through this tunnel. Your provider sees only that the router contacted Cloudflare — not which names the queries were about.

More details

Why it helps: If the upstream certificate does not match the expected resolver, GADNET refuses to query. There is no quiet downgrade to plaintext DNS — a forged reply cannot slip in.

Without it: Your provider can read and rewrite every DNS answer the router asks for. That is exactly how many ISPs inject ads into error pages or redirect typos to their own search engine.

DoQ — DNS-over-QUIC

What it is: The same idea as DoT — encrypted DNS — but carried over QUIC, a newer transport built on UDP. Many lookups can travel in parallel without queueing behind each other, and the secure session survives short network changes instead of starting over.

Example: When a single page kicks off dozens of DNS lookups at once for trackers, fonts, and embedded content, DoQ lets each lookup travel in its own QUIC stream. A slow lookup does not hold up the others — they finish independently.

More details

Why it helps: When the client's network path changes — roaming between WiFi access points, a brief disconnect, waking from sleep — the secure DNS channel survives the move. With DoT or DoH the handshake has to start over after the IP rebinds.

Without it: A single slow lookup can stall the others queued behind it on the same TCP connection. And every time the connection drops, DoT and DoH have to redo the full TCP and TLS handshake before any lookup can go through.

For specialists
Encrypted DNS at GADNET stands on a stack of public IETF standards. The router serves DoH per RFC 8484 on the standard /dns-query endpoint with the application/dns-message media type and ALPN h2, applying RFC 8467 message padding to defeat traffic-analysis side channels. It serves DoQ per RFC 9250 on UDP port 853 with ALPN doq, one stream per query, and the standard two-octet length prefix. Outbound to public resolvers the router uses DoT per RFC 7858 and RFC 8310 in the Strict profile with Authentication Domain Name binding, plus EDNS0 keepalive per RFC 7828. Posture is fail-closed: if the encrypted upstream cannot be reached, queries are refused — there is no silent downgrade to plaintext DNS. Encrypted-resolver discovery follows RFC 9462 (SVCB lookup at _dns.resolver.arpa.) and RFC 9463 (DHCPv4 option 145; the IPv6 RA option ships once full IPv6 enablement lands). Server certificates come from the internal PKI so LAN clients reuse the trust anchor they already hold. TLS floor is TLS 1.2 minimum across every encrypted-DNS surface, with TLS 1.3 preferred wherever the resolver supports it. Each listener is bound per zone — no wildcard 0.0.0.0 or :: exposure.

The Hidden Danger

Router security threats explained

The Hidden Danger

It's 2026. Your phone updates weekly, but Censys 2024 internet-wide scans show a large fraction of home routers still run firmware from 2020 or earlier. It trusts every device that connects, becoming the weakest link in your digital life.

The average home now has 20+ connected devices, and smart-home power users easily pass 35 (Bitdefender + Netgear 2025). If one is outdated, it opens a backdoor to your entire network.

The Castle & Moat Failure

Traditional routers assume "inside is safe". But once a hacker breaches your smart bulb — like the Philips Hue Zigbee bridge takeover Check Point disclosed in 2020 (CVE-2020-6007) — they bypass the firewall entirely. This is called Lateral Movement.

They don't attack your PC directly. They enter through a TV or a bulb, then jump to your laptop. In Feb 2024 CISA documented the same pattern at nation-state scale: the "Volt Typhoon" actors used compromised SOHO routers as pivots into target networks (advisory AA24-038A).

The IoT Botnet Reality

Cheap smart cameras and plugs ship with default credentials and unpatched CVEs. Once such a device hits the internet, botnets like Mirai and Aisuru (2024-2025) can scan and enroll it within hours, sometimes minutes. Over half of IoT devices ship with known vulnerabilities (Forescout Vedere Labs 2024 Riskiest Connected Devices).

Once infected, they become spies in your living room, recording audio and launching attacks on others without you knowing.

The Home Office Risk

Your corporate laptop sits on the same WiFi as your child's tablet and smart TV. A malware infections from a "free game" your kid downloaded can easily jump to your work device, bypassing the VPN entirely.

Sensitive documents and client data stored locally are at risk. Without network isolation, a compromised smart bulb or game console could read your files, encrypt them (ransomware), or use your laptop as a bridge to attack your company.

What is Zero Trust?

(And Why It Changes Everything)

Zero Trust Architecture Visualization

The Simple Explanation

Imagine your network as a hotel. A traditional router gives every guest a master key that opens every room. Once you're in the building, you can go anywhere.

GADNET works differently. It gives each guest a keycard that only opens their specific room. Even if someone steals a keycard, they can only access one room—not the entire hotel.

Zero Trust: the principle that no device, user, or connection should be automatically trusted, regardless of where it comes from.

Default Deny

Block by Default. Whitelist-only access prevents unauthorized connections.

Continuous Verification

Never Trust, Always Verify. Every request is re-authenticated in real-time.

Least Privilege

Minimal Access. Users access only the specific resources they need.

Micro-Segmentation

Contain Breaches. Network divided into isolated, firewalled zones.

Restricted Access

Hardened Perimeter. External ports open only to specific, verified IPs.

Monitoring & Alerts

Full Visibility. Real-time traffic analysis and active intrusion detection.

FAQ

Am I the right user — what skills do I actually need?
GADNET fits home and small-office networks where one person in the household or team is comfortable doing three things: (1) writing an SD card image with a tool like balenaEtcher (drag-and-drop, no command line), (2) following an on-screen setup wizard, (3) plugging in an Ethernet cable. You do not need to understand VLANs, certificates, or post-quantum cryptography — those run in the background. If you have ever set up a home WiFi router or installed an app on your phone, you already have the baseline.
What if something breaks and I am not a sysadmin?
Three safety nets, designed for non-experts in this order: (1) Alpine LBU snapshot rollback — undo a bad config in about 30 seconds from the admin panel; (2) re-flashing the SD card returns the router to a clean state and your encrypted backup restores settings; (3) help on Discord (community) and email (michal@gadnet.pl) — Closed Early Access means a real person reads every message, usually within a day or two.
Do I need to be technical to use GADNET?
No. If you can connect to WiFi and use a smartphone, you can use GADNET. The setup wizard guides you through everything.
Will it work with my existing internet provider?
Yes. GADNET connects to your existing modem via Ethernet. It secures everything behind it.
What about my existing devices?
They will need to reconnect to the new GADNET WiFi. They appear in the Isolation zone until you approve them.
Will Chromecast, AirPlay, HomeKit, and Spotify Connect still work if I put them in a separate IoT zone?
Yes. GADNET runs a selective mDNS reflector that bridges service-discovery announcements between zones you explicitly pair — typically Trusted ↔ IoT. The bridge is policy-driven: only the discovery protocol crosses the zone boundary, and only for the device categories you allow (media receivers, smart speakers, printers). Your phone in the Trusted zone finds the TV in IoT, but a compromised smart bulb cannot use mDNS to scan your laptop.
Is my data stored in the cloud?
No. Everything runs locally on your Raspberry Pi. No data ever leaves your network. No subscription required.
What happens if GADNET fails?
It includes automatic recovery. You can also restore from backup or reflash the SD card in minutes.
Can I use it for my business?
Yes. Its network segmentation supports GDPR (Art. 32) and PCI-DSS v4 (Req 1.4) requirements — GADNET is a tool that helps you meet them, not a compliance certification itself.
Is it really free?
Yes. GADNET is open source. You only pay for the hardware (Raspberry Pi + SD card).
How is this different from a VPN?
Unlike a VPN which typically gives access to the entire network, GADNET allows external access only after strict authorization and limits it to specific, pre-approved resources.

Support GADNET Development

GADNET is free and always will be. It's a one-person project run by Michał Maciak — every contribution goes directly to hosting, test hardware, and dev time.

Closed Early Access means we're actively looking for testers right now (not sales). Financial support helps us accelerate Phase B (OTA updates, LUKS at-rest encryption, end-to-end messaging) and open the public release sooner.
