Is transferring files to my NAS on a home LAN secure?

It’s probably safe, but if you’re really concerned about security, consider encrypting the documents before the transfer. That way, even if someone were to intercept them, they wouldn't be able to read the files. Just keep the unencrypted versions on your laptop until you know the transfer was successful.

Are you really mixing personal financial documents on a work laptop? That’s a bit concerning. It's best to keep personal and work data separate altogether. But if you must transfer these files, just be aware that your local LAN is generally safe if nothing suspicious is going on.

Make sure those financial documents aren't from any work-related systems. It's not advisable to use a work computer for personal tasks. As for transferring files to your NAS, that process itself should be secure enough, but remember, the real issue could be more about accessing those files later on the NAS rather than during the transfer. Also, check with your IT department—many companies don't allow file sharing with personal networks to keep corporate data safe.

Yes, it should be safe! As long as you're using a local IP, your files will stay on your home network and won't be exposed outside. Just keep in mind, if you have any compromised devices connected to your network or untrustworthy guests, that could pose a risk. But if your network is secure, you should be good to go!
