The transition to hybrid infrastructures combining on-premises resources and cloud services has blurred the traditional boundaries of corporate security. The rise of remote work, SaaS adoption, and BYOD policies makes relying solely on network perimeter defense impossible. Today's environment demands a shift to the Zero Trust model ("never trust, always verify"), where every access request is continuously authenticated and verified, regardless of its source.
Key components of the Zero Trust model
Building an effective security system in a hybrid environment requires integrating several technology solutions:
- Identity and Access Management (IAM): centralized access control with mandatory multi-factor authentication (MFA).
- Microsegmentation: dividing the network into isolated segments to limit lateral movement in the event of a breach.
- Monitoring and analytics: continuous user and entity behavior analytics (UEBA) for rapid anomaly detection.
- Context-aware access control: applying access policies based on user role, device health, and risk level.
- Endpoint protection (EDR/XDR): threat detection across all workstations and servers.
Ukrainian developers and integrators, including the member companies of the Intecracy Group consortium (InBase, Softengi, SoftLine, SL Global Service), already have extensive experience in building and deploying such solutions in compliance with ISO/IEC 27001 standards.
What changes for the sector
For businesses and the IT sector, failing to adopt Zero Trust increases the risk of devastating data breaches due to lateral movement within compromised networks. Conversely, transitioning to this model enables organizations to securely scale remote work, adopt cloud services, and ensure compliance with international security standards like ISO/IEC 27001, strengthening trust with global partners.
Readiness assessment: a checklist for CIOs
Transitioning to Zero Trust is a phased process. To define priorities, CIOs should assess their current infrastructure against the following criteria:
- Asset inventory: up-to-date tracking and classification of all IT assets.
- Unified IAM: a centralized identity and access management system for both on-premises and cloud environments.
- MFA deployment: multi-factor authentication enabled for all user categories.
- Principle of least privilege: restricting user access rights to the absolute minimum required for their roles.
- Device control: verifying device security posture before granting network access.
Steps for businesses
To implement the Zero Trust model effectively, organizations should take these practical steps:
- Conduct a thorough inventory and classification of all IT assets to understand what needs protection.
- Deploy unified IAM and enforce multi-factor authentication (MFA) across all user accounts.
- Apply the principle of least privilege and implement microsegmentation to limit access and contain potential breaches.
- Partner with experienced integrators, such as the member companies of the Intecracy Group, to deploy compliant and robust security solutions.
