Just curious do mean something like Quickbooks? Or purely web-based stuff like online banking/investing/etc?
Honestly digital financial safety is probably the same, unless you are habitually clicking links in your email inbox and downloading the file that’s lookhere.pdf.exe. Those exe files simply won’t work at all on Linux. In that sense, Linux is nominally more secure.
At least for now, anti-virus and malware software ($ub$cription$) are not firm requirements on Linux. But that’s bound to change sooner rather than later given the platform is used by more people than ever before - and it is increasing. Keeping current with the security updates and not looking at shady sites, basically good common sense user practices will likely do more than the platform itself. I’m just being honest.
VPN providers, such as NordVPN, are more and more incorporating support for Linux. It’s not universal yet, but it’s going to be fairly soon.
Thanks...web based banking & financial stuff is what I mean...and no we do not click on email pdfs, etc. We use VPN and Bit defender too.
