Why a Zero Trust model is critical for end-to-end enterprise security

In the era of digitalization, data flux and network parity, no business can survive without providing access to or accessing external entities. With increased probability of cybercrime, trojan malware, crypto-ransomware, and data misuse, organizations need an upgraded security model – one that deems both internal and external entities of an organization ‘untrustworthy’ and ‘eligible to breach the security’. Termed as the Zero Trust philosophy, the model administers both the in- and outflux of data and controls access without any bias.

Adopting a Zero Trust security model involves an enterprise-wide transformation that covers four phases:

  • Maturity assessment - The starting point of ZT journey
  • Strategy – A blueprint to meet target state  
  • Foundation: Plan to address identified gaps against Center for Internet Security (CIS) standards
  • Implementation - Strategic tools and controls implementations to achieve ZT security

This phased approach can ensure a smooth transition to a Zero-Trust security model.
