It’s not that fixing Critical and High-Severity vulnerabilities is the problem; it’s that the Medium and Low severity vulnerabilities can pose significant risks as well.

In 2015, it seemed no one was safe from hackers. The year began with Sony reeling from a hack that put the studio and celebrities such as Seth Rogen and James Franco in a web of geopolitics and extortion. Seven months later came the high-profile Ashley Madison hack, which resulted in the release of the email and physical addresses for 37 million users. Cybercriminals stole $1 billion from banks in 30 countries as part of the Carbanak hack.
