Secure Network Transformation
Phased programme to redesign flat networks around zero-trust — micro-segmentation, ZTNA rollout, legacy system brokering, and policy-as-code enforcement. App-by-app, site-by-site, so transformation delivers value incrementally without a multi-year project that stalls.
Overview
Most networks were designed before zero-trust existed. Retrofitting trust after the fact is where projects stall. Secure Network Transformation is the redesign — zero-trust architecture with a managed ZTNA rollout — delivered as a managed programme so the old flat network becomes a verified, least-privilege environment. The transformation is something that actually finishes.
Clevertek scopes every engagement to your environment — capacity, sites, compliance and support model — so you get a tailored plan rather than a fixed SKU. Pricing is quote-only, and our solutions architects will work through your requirements before any proposal.
Our approach
We architect and execute the transition from perimeter-based security to a zero-trust model. This includes redesigning the network around verify-every-request principles, rolling out ZTNA per application, handling legacy systems through controlled gateways, and managing the entire programme to completion.
Why work with us
Programme managed, not just designed
We run the transformation as a sequenced engagement with milestones and accountability. It finishes.
Phased rollout, no big bang
ZTNA is deployed app by app and site by site. Value lands early, and business operations never stop.
Legacy included, not excluded
Older systems that cannot do ZTNA are brokered through controlled gateways. No system left outside the new model.
Key benefits
What this solution delivers for your business.
Least-privilege network access
Every request is verified. Users and devices only access what they need, nothing more.
Reduced attack surface
The flat network is replaced with segmentation and micro-perimeters. Lateral movement is contained.
Compliance ready
Zero-trust architecture aligns with modern compliance frameworks and regulatory requirements.
What's included
Part of this managed service.
Zero-trust redesign
Network architecture rebuilt around verify-every-request principles with least-privilege access and micro-segmentation.
- Verify-every-request architecture
- Least-privilege access model
- Network micro-segmentation
- Identity-based policy enforcement
ZTNA rollout
Zero-trust network access deployed per application with phased cutover and rollback capability.
- Phased per-application rollout
- User and device identity verification
- Application-level access control
- Cutover plan with rollback
Legacy system handling
Older systems that cannot support ZTNA are brokered through controlled gateways with security policy enforcement.
- Controlled gateway brokering
- Protocol translation where needed
- Audit trail for legacy access
- No insecure exceptions
Programme management
The entire transformation is run as a managed programme with roadmap, milestones, and accountable delivery.
- Structured transformation roadmap
- Milestone-based delivery
- Risk and issue management
- Post-transition support
Where it helps
Real-world scenarios where this solution delivers measurable outcomes.
A zero-trust plan that never started
Run it as a managed programme so the architecture is designed and the ZTNA actually rolls out.
A flat network that is hard to defend
Redesign to least-privilege and segment, with a cutover that does not break the business.
Security reviews that keep returning the same findings
A staged programme closes the findings in sequence and leaves evidence behind for the next audit.
Questions buyers actually ask
Is this just buying ZTNA software?
ZTNA is a component. Transformation includes the architecture, rollout, and legacy handling around it. The difference between a tool and a finished state.
How long does it take?
Phased by design. We sequence app by app and site by site so value lands early and operations keep running. The pace matches your risk.
What about systems that cannot do ZTNA?
We broker them through a controlled gateway so they sit inside the policy envelope. No system is left outside the new trust model.
How do you price a transformation programme?
Quote-only, after a scoping workshop. We size it from your application inventory, site count and legacy systems, then stage the cost across phases so each phase can be approved on its own merit.
What happens if a phase causes an operational problem?
Every phase carries a cutover plan and a rollback path. If a rollout disrupts operations, the previous access model is restored before the next change window opens.
Do you stay on after the transformation ends?
Yes. Most clients move into managed ZTNA and network operations with us, so policy changes, access reviews and reporting continue under one service level agreement.
What does the first phase actually deliver?
A complete application and identity inventory, the target architecture, and a sequenced rollout plan with the highest risk access paths addressed first. That plan stays usable even if the programme is later paused.
Do we need to replace our firewalls?
Not necessarily. Existing perimeter controls usually remain through the transition and are retired only where ZTNA and segmentation make them redundant, rather than replaced on day one.
