I am a lawyer and, when carrying out process protocols, the electronic system uses .jnlp (java) files. On MacOS Sonoma, I accessed the file by pressing the "right button" on the mouse and clicking "Open". Now, on MacOS Sequoia, I have to access the "Privacy and Security" settings every time and authorize the file to be opened there. Although it enters the exception list, but each .jnlp file is unique, so the system will never identify it in the exception list. Would there be any other option for me to place files, in general, on the MacOS Sequoia exceptions list, without me having to authorize it, every time, through the "Privacy and Security" item?

A suggestion: before following any advice you see on message boards, especially anything that involves permanently changing security settings, have a look at the posting histories of the people providing advice. You will want to make sure that a poster's background, usage habits, attitudes towards security, and, if any, professional requirements match yours. For example, a long-retired person who mainly uses their 15-year old Mac for email and social media has much different needs than a management consultant who stores privileged client information, creates confidential documents, and is subject to compliance and oversight regulations.

Personally, I always try to keep in mind that nobody on an Internet message board will be available to answer to me if I follow bad advice or take an action that turns out it be ill-suited to my situation. The same goes for bloggers, websites, and social media. Only one person can decide what is truly best for me: ME.

You mentioned an excellent point! Really the only person who can know if the attitude of deactivating the Gatekeeper is only me. I'm a lawyer and my Mac use is practically 90% for work. I deal with Word and PDF documents only. I don't download apps or pirated games all the time. In fact, I don't even play on Mac. Back when I had more time to research and when I had Windows, I modified the system, downloaded apps to speed up its performance and so on. But today, I don't even have the patience or time for that.

If it weren't so annoying to keep going to "Privacy and Security", accepting the risk and putting your finger on TouchID for every request I have to make, I wouldn't be here asking for help. However, my fear of damaging the system or leaving it with security holes by deactivating GateKeeper is greater than my patience in following these steps for each petition protocol.

Although I consider it to be useless, I keep Gatekeeper in the default configuration.
As proven a few posts back, bypassing Gatekeeper is trivial.
Apple notes: "Gatekeeper can also be completely disabled, if necessary."

The funniest thing is that in Sonoma you just clicked on the file with the right mouse button and "open". Ready. The system was already aware that I wanted to open the file and take the risks. If I double-clicked on the file, the system warned me about the malware. They could have kept that at Sequoia.
