I was pleasantly introduced to a non-profit cybersecurity company this week. Quad9 was established 6 years ago with the goal of reducing human error as the source of breaches, which makes of more than 90 percent of all successful cyberattacks. And they do it for free. Their website (www.quad9.com) has a lot of easy to understand and use tools to block malicious actors from accessing your systems and data. Check it out.
