ZERO TRUST & IDENTITY SECURITY
Turn Zero Trust Into an Operating Model
Zero Trust changes how access is decided. A user, device or workload does not receive broad trust because it is inside a network, owned by the organisation or successfully authenticated once.
Digisecuritas helps organisations establish the required visibility, policies and enforcement points, then turn them into a practical roadmap that works across existing technology and business priorities.
Independent strategy. Platform-neutral architecture. Measurable priorities.
TRUST EVALUATION PATH
REQUEST CONTEXT
RESOURCE
POLICY DECISION
PROTECTED RESOURCE
Monitor the session • Re-evaluate risk • Change or revoke access
Reduce implicit trust
Remove access based only on location, ownership or a previous decision.
Limit unnecessary reach
Give people and systems access to the specific resources they need.
Use better context
Bring identity, device, behaviour and resource sensitivity into access decisions.
Respond during the session
Detect changing risk and challenge, restrict or revoke access when needed.
THE ZERO TRUST OPERATING MODEL
Zero Trust succeeds when the control pillars work together
NIST defines Zero Trust as an approach that removes implicit trust based solely on network location or asset ownership. Authentication and authorisation occur before a session to a protected resource is established. NIST SP 800-207 Zero Trust Architecture
Identity
Establish confidence in the person or system requesting access.
QUESTIONS
- —How is the identity verified?
- —Which authentication strength applies?
- —Is privilege proportionate?
- —Is the account still valid?
EVIDENCE
Devices
Use device state as an input to access decisions.
QUESTIONS
- —Is the device known?
- —Is it managed?
- —Does it meet the required security condition?
- —What access should personal devices receive?
EVIDENCE
Networks and environments
Restrict pathways without treating network location as proof of trust.
QUESTIONS
- —Which paths expose sensitive resources?
- —Can access be made application-specific?
- —Where is segmentation required?
- —Which legacy connections remain?
EVIDENCE
Applications and workloads
Protect applications, APIs and services according to their purpose and risk.
QUESTIONS
- —Which identities can reach the workload?
- —Are service-to-service connections authenticated?
- —Can high-risk actions require stronger controls?
- —Is access logged?
EVIDENCE
Data
Align access with the sensitivity and permitted use of information.
QUESTIONS
- —Where is sensitive data?
- —Who can access or export it?
- —Do controls follow the data?
- —Can unusual movement be detected?
EVIDENCE
CISA's Zero Trust Maturity Model uses identity, devices, networks, applications and workloads, and data as its principal pillars, supported by cross-cutting capabilities. Use it as one maturity reference rather than a mandatory product architecture. CISA Zero Trust Maturity Model

HOW WE WORK
Start with resources and access paths, not products
01
Define the outcomes
Identify the business services, data, users, workloads and risk scenarios that the programme must address.
02
Establish the current state
Review architecture, control coverage, operating processes and available telemetry across the Zero Trust pillars.
03
Design the target state
Define policy decisions, enforcement points, required signals and ownership while accounting for existing technology.
04
Sequence the roadmap
Prioritise changes by risk reduction, dependency, business impact, cost and implementation readiness.
NIST's final implementation guide includes multiple example Zero Trust architectures, reinforcing that organisations can reach Zero Trust outcomes through different technical designs. NIST SP 1800-35
What prevents Zero Trust programmes from progressing
A product-led starting point
Technology is selected before the organisation defines the resources and access risks it needs to address.
Incomplete identity coverage
Employees receive stronger controls while suppliers, administrators and machine identities remain outside the model.
Missing device context
Access policies cannot distinguish between managed, personal, compliant and high-risk devices.
Broad network access
Users continue to receive reach across network segments when they need only specific applications.
Unclassified resources
Teams cannot apply proportionate policies because application and data sensitivity remain unclear.
Limited ownership
Identity, endpoint, network, cloud and data teams pursue separate projects without shared outcomes.
What your organisation receives
A Zero Trust plan tied to specific resources, access paths and accountable decisions.

Independent direction across the whole security environment
Outcomes before products
The programme begins with protected resources and credible access risks.
Identity within a wider model
Identity remains central while device, application, network and data controls receive equal attention.
Existing investments considered
Current platforms are assessed before new technology or replacement is recommended.
A roadmap teams can own
Every phase identifies business outcomes, control owners, dependencies and verification criteria.
