FEATURES
Black Hawthorn IT Suite
Two tools. One key. Everything you need in the field.
Hawthorn Probe scans your clients' networks for open ports, running services, and known vulnerabilities — and turns the results into a professional report you can deliver the same day. Built for MSPs who need to assess fast, document clearly, and move on to the next client.
Hawthorn NetTrace is your go-to tool for diagnosing DNS issues, validating email security configurations, and tracing network paths — all from a single interface. Run a full domain audit in minutes and export the results for your client or your records.
FEATURES
Black Hawthorn DojoBase
DojoBase is a complete dojo management system built for martial arts schools of all sizes — students, attendance, belt ranks, payments, inventory, events, and exams. All from a single fast interface that runs on your computer. Your data never leaves your machine.
FEATURES
The4Wheel Shop
Run your auto repair shop - customers, vehicles, estimates, invoices, parts, and payments in one app that lives on your computer.
Works when the internet doesn't.
English and Spanish.
Built for independent shops that are still writing tickets on paper, juggling spreadsheets, or paying $250–400 a month for cloud software that stops working when the internet goes down.
The4WheelShop gives you the full picture - who came in, what you did, what they paid, and what you actually earned, for less than most shops pay in a single month.
FEATURES
Black Hawthorn WealthBase
Know where you stand, and make sure your family does too. Track what you own and what you owe, learn the money basics nobody taught you, and keep everything your family would need in one private app on your computer. No monthly fees. No bank logins. No cloud.
