The present threat landscape has grown to the point where a single security measure is no longer sufficient to protect against attacks. The statistics below attest to this:

• Cybercrime damages are expected to cost $6 trillion per year by 2021.
• Phishing increased its prevalence from 25% last year to 36% this year.
• Ransomware doubled in frequency since last year, appearing in 10% of verified breaches.

Because no security technology or measure is flawless or guaranteed, layered security assumes that attackers will infiltrate different layers of an organization’s defenses. The goal of this approach is to provide several layers of protection to identify and stop attackers at every stage of the attack cycle, thus enhancing security system effectiveness.
