The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. Watch espn app mac. If there’s ever a problem with an app, Apple can quickly remove it from the store.
Whenever you launch a new application on your Mac, Gatekeeper checks to see that it’s signed with a valid signature. If the application is signed with a valid signature, it’s allowed to run. If it’s not, you’ll see a warning message and your Mac will prevent the application from running. But not every Mac app is signed.

If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.

If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.

According to Java website (first reference), 'Starting with Java 7 Update 51, applications without a certificate (i.e. unsigned apps), or missing application Name and Publisher information are blocked by default. Running this kind of application is potentially unsafe and present higher level of risk.' This can cause issues for internal applications which are typically unsigned and does not provide a clear solution for allowing these applications to run.
Oracle's suggested response to this problem is as follows: 'It is highly recommended to not run this type of application. However if you understand the risk and still want to run the application, you can add the URL of this application to Exception Site List, which is located under the Security tab of the Java Control Panel. On successfully adding this application URL to this list will allow it to run after presenting some security warnings.'
Follow these steps to add the website to the Exceptions Site List (as per the second referenced site below):

I needed to join a Microsoft Live meeting session at work and was instructed to use Firefox with Java. I installed the latest version of Firefox (42.0), latest version of Java (8) and the nightmare began. First It kept blocking access to the web console. I added the link to the exception list as described above and disable some of the security settings in Java just so I could join this meeting. Then, Instead of the blocked access notices Firefox started to crash, I kept getting the 'Plugging not working' message and Firefox just stopped working, by the way, the same thing was happening when I tried IE. I verified that the 32bit version of Java was running, made sure the add-ons were active in Firefox, I checked everything. Could not make the thing work. The only way I was finally able to join the meeting was by installing Java version 6.
