When we run our test cases in in parallel using TestNg in selenium, you might have faced issues like some environmental, or some unknown issues halting the parallel execution.
Parallel execution is nothing but running the selenium in multiple threads, when one thread interrupts the other thread then JVM throws exceptions

WebDriver driver = ThreadGuard.protect(new FirefoxDriver());
This class has no importance than protecting the webdriver on the multi-threads.
