Running cybersecurity tests is essential for every respectable company. To be adequately protected, you must contract a cybersecurity company that will carry some advance cybersecurity tests to your company networks, like penetration tests, and ethical hacking tests. This kind of checks must be made every year because cyber security threats evolve and you must find and fix any cybersecurity flaws as soon as they are discovered. If you are not running Linux, the presence of antivirus for Windows or antivirus for Mac is a must in every device that you own.
