Zero Trust Security Consulting Services

Zero trust operates on the premise that no user, device or system should be granted implicit trust based on their location. Every data or capability request undergoes verification, regardless of whether it originates from within the traditional network perimeter or externally. This approach effectively ends the notion that the office network represents the secure side of the fence.

Scope of Coverage

• Identity-centric approach: All access decisions are grounded in a verified identity, applying equally to individuals, services and machines.
• Least privilege: Access is restricted to the specific task and resource required, rather than assigning broad roles that encompass multiple permissions.
• Ongoing verification: Permissions can be revoked as context shifts, such as when a new device is detected, a risky location is identified, or unusual activity patterns emerge.
• Network segmentation: By restricting lateral movement, this strategy ensures that a compromise in one area does not spread across the entire environment.

Significance

• Remote and hybrid work: The reliance on users being within a protected network is no longer valid, rendering traditional security models based on that assumption obsolete.
• Third-party access: Vendors, contractors and integrations require the same level of scrutiny as internal staff, a challenge that arises when the network perimeter was the primary security barrier.
• Attack surface: Any service accessible without verification presents an unsecured entry point. Reducing these exposures lowers the likelihood of a breach, not just its potential impact.

Considerations

• User experience friction: Additional verification steps can slow down legitimate work. The design must carefully balance the cost of friction against the risk of leaving open access points.
• Identity management complexity: As the number of identities (human, service or machine) increases, the scope of required oversight expands accordingly.
• Legacy infrastructure: Older systems often struggle with per-request verification. Prioritising the protection of the most sensitive assets is a more practical strategy than attempting an immediate, comprehensive overhaul.
