Safe sourcing

Where to get each tool

Scanlanmax hosts no files and never will. This page lists where each tool really comes from, and how to check what you receive before you run it.

Why we don’t offer copies

Network scanners are a favourite disguise for unwanted software. Look-alike sites buy search ads for popular tool names, wrap the genuine program in a bundle of extras, and count on people clicking the first result. The safest habit is simple: get every tool from the organisation that makes it, and check the file before running it. We could not make a copy safer than the original, so we don’t make copies at all — every link below goes to the vendor’s own product page.

The vendor’s own site for all 9 tools

Tool	Made by	Licence	Official site	What to check
Advanced IP Scanner	Famatech	Freeware	Download for Windows	Windows file — the digital signature should name Famatech.
Angry IP Scanner	Anton Keks	GPLv2	Download for Windows	Follow the release links on angryip.org itself; compare the checksum where the project lists one.
SoftPerfect Network Scanner	SoftPerfect	Commercial	Download for Windows	Windows and macOS builds — the code signature should name SoftPerfect.
Fing	Fing	Free + paid tiers	Download for Windows	Phones: the App Store or Google Play listing published by Fing. Desktop: only via fing.com.
Advanced Port Scanner	Famatech	Freeware	Download for Windows	Windows file — the digital signature should name Famatech.
Nmap	Nmap Project	NPSL	Download for Windows	nmap.org publishes SHA digests and GPG signatures for every release; on Linux, your distribution’s package is fine too.
Wireshark	Wireshark Foundation	GPLv2	Download for Windows	wireshark.org publishes signed SHA-256 hashes; Windows and macOS builds are code-signed.
Lansweeper	Lansweeper	Commercial · trial	Download for Windows	Start from a trial sign-up on lansweeper.com; the scanning component comes from your own account area.
LizardSystems Network Scanner	LizardSystems	Commercial	Download for Windows	Windows only; the product page lists a SHA-256 for the current build — compare it with Get-FileHash before running.

Links open the vendor’s site in a new tab. We are not any of these vendors and receive nothing when you follow a link.

The five-minute verification checklist

Arrive at the right address. Type the vendor’s address yourself or use the links above rather than clicking a search ad. Look-alike domains often add a word (“-free”, “-pro”, “-app”) or swap the ending.
Prefer the vendor page over any mirror. If a page asks you to switch off antivirus, enter a password to open an archive, or accept “recommended offers”, close it. None of the tools on this site require any of that.
Check the digital signature on Windows. Right-click the file, choose Properties, thenDigital Signatures. The signer should be the vendor named in the table. In PowerShell:
```
Get-AuthenticodeSignature .\the-file-you-received | Format-List Status, SignerCertificate
```
Status should read Valid.
Check the signature on macOS. Gatekeeper checks this on first launch; you can check it yourself in Terminal:
```
codesign --verify --deep --strict --verbose=2 /Applications/AppName.app
spctl --assess --verbose /Applications/AppName.app
```
The second command should report accepted and name a developer you expect.

Compare the checksum when the vendor publishes one. Nmap and Wireshark list SHA-256 values for each release. Compute yours and compare every character:

# Windows (PowerShell)
Get-FileHash .\the-file-you-received -Algorithm SHA256
# macOS
shasum -a 256 the-file-you-received
# Linux
sha256sum the-file-you-received

On Linux, the easiest trustworthy route for Nmap and Wireshark is usually your distribution’s own package manager (sudo apt install nmap, sudo dnf install wireshark and similar), which verifies packages for you.

Keep your antivirus switched on

Some security products flag network scanners as “potentially unwanted” simply because scanning is what they do. If that happens with a file you obtained from the vendor and verified as above, add a specific exception for that one file or folder — never turn protection off wholesale, and never follow a site’s advice to do so. If the signature or checksum does not match, delete the file and start again from the official site.

After you have it

Point the tool only at networks you own or administer, or have written permission to survey. If you are not sure where to start, the IP scanner comparison explains which tool suits which situation, and our walkthroughs take you through common jobs step by step.
