When it feels like everybody is out to get you, there's only one way to survive: Trust nobody. You may not have too many physical enemies ready to jump you, but there's an army of hackers wanting to breach your company's database. One of the securest ways to keep your company's information safe is to implement a "zero trust" network security model.
Take a moment to consider your answer to this question, "What would you do if all of your business's data was somehow lost overnight?" How would you react, and what would you do about it? Your data is valuable, so much in fact that your business would be lost without it, and likely wouldn't be able to run properly.
Data security should be a top priority for every business. Having good security means identifying risks. Surprisingly, some of the biggest data risks come from within. If employees aren't following your organization's data management policies, then they're your biggest threats.
