Details are cheap. Shortcuts are not.
I have used this platform to remind business owners that they need to check and assess their security for years. The reason is that security issues arise because the details are overlooked.
If you don’t pay attention to the details when building a house the house will be unstable and have issues. If you skip the details when finalizing your masters thesis your degree is in jeopardy. Skipping these details does speed up the outcome, your house is finished early and the paper is done without much added effort. But neither will lead you to the desired long term result.
You simply cannot overlook any detail when evaluating your network security. There is no shortcut, no tool to run, no website with a click-to-fix button that solves this.
