How SecureScore™ Works

When you read one of our SafeHome.org reviews, you'll see something called a SecureScore™. What is a SecureScore™? Simply put, it's our measure of how well a product or service held up to our rigorous review process.

Each SecureScore™ is pegged to our simple and standard scale of zero to 10, so that you can quickly and easily compare products and services. The scale is simple, but the numbers are precise: each SecureScore™ is measured out to one decimal point, and a product or service's overall SecureScore™ is determined by the individual scores we assigned to categories like customer service, value, and ease of use. Our scoring system aims to distill every concrete detail and factor in the arbitrary aspects like a company's business ethics, history, sustainability etc. You'll find this in one at-a-glance score.

Why You Can Trust SecureScore™

Lots of reviews use numbers or other grades to summarize their findings. We gave our scoring system a name because it's so central to what we're all about here at SafeHome.org. With SecureScore™, we drill down to individual categories and are as specific and objective as possible in our scoring. But SecureScore™ also gives us a straightforward and simple final score that helps you make comparisons and find the right security solutions for you and your family.

Most importantly, our SecureScore™ ratings are ones that we can stand behind. Every one of them is the result of one of our reviews, and every one of our reviews is the product of our expertise, hands-on testing, and careful research.

Our expert researchers and writers build our reviews methodically, which allows us to assign specific scores to each category and calculate our final SecureScore™.

In other words, each SecureScore™ you see is a precise result generated by our extensive and objective review process. We know our readers may not have time or the resources to build a lifetime of security expertise and then try each product or service themselves — so we took our own expertise and research and turned it into an at-a-glance metric that you can trust.
