In the context of recent changes related to the introduction of the GDPR, there is a lot of talk about the need to ensure data security. This security should be important not only for people who leave their data but also, and perhaps above all, for those who collect and process this data. Those who do not genuinely care about security now have one more argument against each themselves. Beginning July 2018, Internet browsers such as Google Chrome, Safari, and Firefox mark sites that do not have an SSL certificate as not safe. In a nutshell, this means that every visitor will receive a message saying that the page being viewed is not secure. This is a change to the previous approach, which until now has distinguished between secure pages, in view of the fact that it was considered that the page's security is no longer a distinguishing feature, but should be a standard.
