What is automatic updates in WP

I do hope I am placing this request in the correct forum.

I had been using WordPress, for blogging about bread making, for many years and between 2011 to 2103 my WP site was badly hacked several times. As a result, I decide for once and for all to try to put an end to all the hackers. After almost 2 years of development and testing the anti-hacking firewall for WordPress sites, I have put it up for sale at other forums, it is called The Bad Bot Exterminator. It was designed to block known and unknown bad bots and hackers.

It comes with a free cache controller, the SuperFast Cache, a WP plugin. When both, the Bad Bot Exterminator and the SuperFast Cache were implemented at my website there were good performance improvements to the WordPress blog.

The improvements are:-
1. One of my WP post webpages download times had amazingly improved from 12 seconds to 4 seconds – the results were generated by testing on GTmetrix. Generally all my WP webpages download times improved by a factor of x2 to x3.

2. It has been so effective over the last few months it has block 147 bad bots & hackers and blocked 1 DDoS attack (they could not crash my site) and

3. As a result of installing both programs on my WordPress website, my server CPU usage has dropped from 3 – 5% range to 1.4 – 1.8% range even though I have been having about 500 visitors per day for a very long time.

It allows you to LOCK up your WP site so that no one can log in into your WP site. I have had many hackers trying to log into my site for years but all have failed.

One of my customers just informed me that “Future security updates will be applied automatically”. What does this mean? Will it automatically update and overwrite all WP scripts? Is there a way to stop this from occurring? That is WP will not upgrade until the web publisher clicks on upgrade button?

Unfortunately if WordPress is upgraded automatically there may be a loss of the firewall if the firewall is not turned off before WP upgrading. The Bad Bot Exterminator was written as a firewall and not as a plugin so it has to be turned off before WP can be upgraded. Subsequently, after upgrading WP the firewall can be turned on.

Can WP developers have a button, in the WP DashBoard, for my clients to select whether they want automatic upgrades or manually activated upgrades or don’t implement automatic upgrades? This will allow them to turn off the Bad Bot Exterminator Firewall before they begin the WP upgrade.
