Never trust. Always verify.
Identity, everywhere.
Start with explicit identity, access and network boundaries. Use the architecture below to discuss the controls your workload needs; implementation and compliance evidence require engagement-specific review.
Six layers to review for explicit access decisions.
Conceptual areas to examine during an assessment. The diagram does not establish that these controls are deployed or verified for a particular workload.
Confirm the authoritative identity and supported policy signals for this access path.
Select a layer to review its assessment questions. This illustration does not display live access decisions.
- 01Identity
Identify authoritative user and workload identity providers, immutable identifiers, sign-in policies and authorization boundaries.
- 02Access broker
Assess remote-access workflows, target permissions, credential lifetime and session records. Confirm what the chosen broker supports.
- 03Network
Map tenant and workload boundaries, permitted flows, segmentation controls and service authentication requirements.
- 04Workload
Review compute isolation, patching, boot integrity and encryption options against the selected platform and workload requirements.
- 05Data
Define encryption, key custody, data access and recovery requirements. Verify supported controls and responsibilities for each data class.
- 06Observability
Identify required events, collection paths, retention periods and review responsibilities. Validate representative evidence before acceptance.
Each layer enforces the same identity-based policy decision. A compromise at one layer does not grant access at the next.
What “zero-trust” actually means here.
Use these principles to define assessment questions and implementation evidence for your environment.
Verify explicitly, every request
Use explicit identity and authorization checks at defined access boundaries. Do not grant trust solely because a request originates inside the network.
Assume breach, contain blast radius
Identify likely compromise paths and design segmentation to limit lateral movement. Test the boundaries and document remaining exposure.
Least privilege, by default
Define the minimum access each role and service needs. Review standing privileges and assess time-bound elevation where supported.
Continuous verification
Define which device, identity and session signals can trigger re-evaluation. Agree response actions and operational ownership.
Identity-everywhere, not perimeter-first
Map users, services and access paths to policy enforcement points. Verify each integration instead of assuming uniform coverage.
Audit at the workload, not just the edge
Specify the actors, actions and outcomes that must be logged. Test collection, retention, access and evidence retrieval for the agreed scope.
What changes when identity becomes the perimeter.
Side-by-side: the assumptions you grew up with, vs. the assumptions Ultiblob ships with.
| Legacy perimeter | Ultiblob zero-trust |
|---|---|
| Login once to the corporate VPN; you're trusted on the network | Explicitly authorize access to each protected resource using the signals and policies supported by the design. |
| Engineers SSH to bastions, then jump to VMs with shared keys | Assess identity-bound access, limited credential lifetime and session logging for each administrative path. |
| Internal services trust each other by IP | Define and test service authentication and segmentation at the intended enforcement boundaries. |
| Compliance evidence is a quarterly screenshot exercise | Specify audit events and verify their collection and retrieval for the selected workloads. |
| Vendor accesses your data with their key custody | Agree the key-custody model and test who can encrypt, decrypt, administer and recover data. |
What zero-trust looks like for your industry.
Healthcare
Define patient-data access, logging, encryption and recovery requirements with the responsible application and compliance teams. Verify the agreed controls before handling sensitive data.
Finance & tax
Review privileged access to financial applications, data boundaries and required audit records. Confirm integration support and evidence requirements for the selected systems.
AI startups
Map model, inference and retrieval data flows. Define service permissions, key custody and data-retention boundaries, then test the chosen implementation.
Zero-trust, asked + answered.
It is an architecture approach that avoids granting trust solely from network location. A scoped assessment identifies identity, access, segmentation and logging controls to implement and test; it is not a guarantee against breaches.
An assessment can define phased improvements around existing systems. Dependencies, access needs and migration risk determine the sequence and schedule.
The useful distinction is evidence for your environment: which controls are implemented, which paths they cover, how they are tested and who operates them. A product label alone does not establish that coverage.
NIST SP 800-207 provides concepts and deployment models for zero-trust architecture. A project-specific mapping and validation would be needed to assess an implementation; no completed Ultiblob mapping or attestation is offered on this page.
VPN requirements depend on the applications and access paths involved. Review authentication, authorization, segmentation and monitoring for each path before changing access.
