Zero Trust security concept is a model and framework developed by former Forrester analyst John Kindervag in 2010. Since then, the Zero Trust model is widely adopted, with leading researchers at Gartner, Microsoft, and Google all developing and implementing their variations of Zero Trust frameworks while keeping the core concept intact.

Emergencies such as natural disasters or pandemics force organizations to take measures for establishing work-from-home procedures. One of the first security measures organizations must implement for remote work is multi-factor authentication (MFA). Multi-factor authentication is a method to protect access to corporate networks and business-critical systems, both on-premises and remotely. It requires an employee or a partner to provide at least two authentication factors to confirm his or her identity and login credentials.
