How are TSA Scores determined?
The Software Authority strives to be different! Our results are based on factual data and you will never see a non-certified product that you never heard of being rated highly for the sole purpose of pushing sales like we often see on other review sites.
With increasing computer processor speeds being able to handle heavy workloads and improving performance significantly, TSA Scores are focused more on how well a security product protects your system from malware, viruses, and threats as opposed to how much system impact does this security product have. Reality is, if you obtain a nasty Ransomware virus as an example, does having a product that uses limited computer resources matter if you can no longer access your computer?
The TSA Score is determined by analyzing the latest review data from multiple independent testing laboratories, other reputable third party review sites and our many years of experience in the security software industry. The results from these sources are then inputted into a proprietary formula that determines the final TSA Score.
