Posture Scanner

A small program you download and run on your own computer. It checks your machine's security settings — firewall, disk encryption, updates, accounts, and more — and tells you, in plain English, what's solid and what to fix.

🔒 Everything stays on your machine. The scan runs locally and the results are shown to you only. Nothing — no findings, no inventory, no telemetry — is ever sent to ByTE X Bit or anyone else. No account, no cloud, no phone-home.

Start free, upgrade when you're ready. Download and run the free scanner first — Pro is the same tool with live vulnerability confirmation and continuous monitoring unlocked, so you only pay if you want the extra.

BXB Posture Scanner Pro

$50 / year · cancel anytime

The same scanner with more unlocked: it confirms what's actually exploitable on your machine, then keeps watching — so you don't have to think about it.

✓
Version-confirmed exposure — whether your exact version is hit by an actively-exploited (CISA KEV) flaw, with the CVE, fix deadline, and what to do
✓
Full local-network map — see every device on your network with its name, maker, and device type, found passively (ARP + reverse DNS + SSDP/UPnP) — never a port scan
✓
Continuous monitoring — a daily background check alerts you the moment a new risk appears or something slips
✓
"What changed since last time" — your score trend and exactly what improved or regressed
✓
Broad, growing coverage — Chrome, Firefox, Java, WinRAR, Adobe Acrobat/Reader and more, refreshed automatically
✓
Always current — the app tells you when a new version is out
✓
Only product + version checked; nothing else leaves your machine

✓ Digitally signed by ByTE X Bit Technologies LLC

These downloads are code-signed, so Windows shows ByTE X Bit Technologies LLC as the verified publisher — not an "Unknown Publisher."

Because our signing certificate is newly issued, some systems may still show a brief SmartScreen confirmation while it builds reputation over the coming weeks. If you see one, click "More info" then "Run anyway" — you'll see our verified name on it. Every release also ships with a SHA-256 checksum (SHA256SUMS-0.4.3.txt) so you can verify the download hasn't been tampered with. macOS support is coming.

How to run it

Windows

Double-click the downloaded
bxb-scan-0.4.3.exe
A menu lets you pick:
  1) this computer only
  2) computer + local network
then offers to save a report.

Linux

chmod +x bxb-scan-0.4.3
./bxb-scan-0.4.3
(shows the same menu; or use
 --host-only / --network / --html)

The menu offers to save an HTML report you can keep or print (or pass --html report.html directly). It runs fine as a normal user; on Windows, a few checks (like BitLocker) show more detail when run as Administrator.

What it checks
✓
Host firewall — on or off
✓
Disk encryption — BitLocker / LUKS
✓
Endpoint protection — antivirus active
✓
Updates — auto-update & pending patches
✓
Admin accounts — how many have admin
✓
Risky settings — SMBv1, SSH root login
✓
Installed software — inventory
✓
Local network map — every device by name, maker & type (Pro)
✓
Plain-language fixes — for every gap
By default it checks the computer it runs on. Pro adds a full local-network map: turn on "Also scan my local network" and it lists every device on your subnet with its hostname, maker, and device type — using your computer's ARP cache, reverse DNS, and standard service-discovery (SSDP/UPnP). It never scans ports and stays on your local subnet. (Authorized active port scanning is a separate, opt-in step that always asks you to confirm.)

Found something worth fixing?

Whether it's your own computer, your household's devices, or a whole business, I'm a security professional in Maryland who can handle the fixes for you. A short paid triage confirms exactly what's needed, and the fee credits toward the work.
