New security threats emerge almost continuously, meaning we deal with a known unknown. In the past year alone, malware and ransomware use has sharply increased. 43% of total breaches focused on web applications, and the trend of new vulnerabilities in hardware has continued to accelerate.

The key is to find a balance that makes sense for the business and allows them to manage their risks.
