The Perimeter That No Longer Exists
Here's the uncomfortable truth that most CIOs already know but haven't fully internalised: the security perimeter you've spent decades fortifying doesn't exist anymore.
Employees work from home, coffee shops, and airports. Applications live in multiple clouds. Partners access your systems directly. The perimeter is gone.
Understanding Zero-Trust: Principles Over Products
Zero-trust is not a product. It’s an architecture built on a single principle: never trust, always verify.
- Identity is the new perimeter
- Least-privilege access
- Assume breach
- Verify explicitly
- Microsegmentation
The Identity Imperative
Over 80% of breaches involve compromised credentials. Identity security is now the most critical security control.
Zero-Trust Architecture
- IAM, MFA, PAM, IGA
- ZTNA replacing VPNs
- SASE & cloud security
- EDR, SIEM, SOAR
- DLP & encryption
The Nexora Cybersecurity Approach
Nexora implements zero-trust through a phased approach: architecture, identity, network, cloud, SOC, and data governance.
Executive Summary
Zero-trust replaces obsolete perimeter security with identity-first architecture, enabling secure cloud adoption, remote work, and digital transformation.
