Security
An action plan, not a list of alarms

Build a complete inventory
Identify every device with IP, MAC, vendor, name, model, operating system, open ports and category.
Know what to fix first
A 0–100 score and a step-by-step plan: risky ports (Telnet, RDP, SMBv1…), weak Wi-Fi or WPS, a router with dangerous port forwards.
Track your network events
Who joined, who left and which risky ports appeared, with date and time, from your web dashboard.
Passive security: everything an attacker would try, without trying anything
LanFaro only reads what your network already publishes. It never tests passwords, never exploits flaws and never changes the router configuration. That is why you can use it on a client's network without asking for an intrusion-test authorisation.
Exposed services and SMBv1
Telnet, remote desktop, databases or Docker open to the network, and devices that accept SMBv1 (the WannaCry one) or don't require signing. Checked without user or password.
Router and Wi-Fi
UPnP forwards to cameras, WPS on, a twin Wi-Fi with weaker encryption, a rogue DHCP server and hijacked DNS.
Poor segmentation
Cameras and IoT on the same network as PCs, devices asking the whole network for names (LLMNR/WPAD) and router management in plain view.
Firmware and certificates
Matches what each device announces against a curated table of public advisories (CVE and end of life) and reads each panel's HTTPS certificate: expired, self-signed or weak.
✓ Passive DHCP/mDNS/SSDP listening without drivers, and in the app you see everything that leaves your computer ("What leaves this computer").

Frequently asked questions
›Does LanFaro read my traffic or passwords?
No. It only uses ping, your system's ARP table, DNS/mDNS/UPnP, TCP connections to common ports and a read of each HTTPS panel's certificate, like a browser. It never intercepts content nor tests passwords.
›Do I need an account to use the app?
Yes, and it is free. With an account your networks, alerts and history follow you to any computer. The Free plan includes full, unlimited scanning; data is uploaded only if you enable it.
›Can I cancel anytime?
Yes. From Plan & billing, in one click. You keep access until the end of the paid period, with a 14-day guarantee on the first payment.
›Where is my data stored?
In Supabase (database) with per-user isolation. You can download everything as JSON or delete the account instantly.
›Does LanFaro attack devices or change my router?
Never. It is a product decision: it does not test credentials, exploit vulnerabilities or automate router changes. Quarantine and blocking are guided: you do them in the router panel and LanFaro verifies the result.
›What happens when the 14 days of Pro end?
You move to Free and nothing is charged: you keep scanning without limits and with every security check.
›Can I see prices in my currency? Is there an invoice?
In some countries you see an approximate price in your currency; it is charged in US dollars. Lemon Squeezy issues the invoice and handles taxes.
›Why does Windows show SmartScreen on opening?
The app is not signed with a commercial certificate yet. On Windows: “More info → Run anyway”. The macOS version is coming soon.
›Does it work on my phone?
The web dashboard installs as an app on your phone and gets push notifications. Scanning is done by the desktop app or the 24/7 agent.
›How is it different from Fing?
Fing recognizes more exact device models. LanFaro explains each device's risk and what to do first, checks the router, Wi-Fi and segmentation without drivers, scans without limits on Free and produces branded reports.
