Secure Network Transformation
Legacy WAN architectures operate on an implicit-trust model: location inside the perimeter equals trust. Secure Network Transformation replaces this with identity- and device-centric access controls deployed as a managed overlay — SD-WAN, SASE, ZTNA, and 24x7 SOC delivered as one coordinated program so your network engineering team focuses on business outcomes rather than control-plane maintenance.
Overview
Clevertek transforms your existing WAN into a zero-trust architecture without requiring a greenfield deployment. We overlay SD-WAN on top of your current transport mix — Internet, Broadband, MPLS and LTE — applying application-aware routing so each flow traverses the optimal path by latency, jitter, and cost policy rather than the single circuit you previously procured per site. Above the WAN overlay we deploy SASE: a converged cloud-delivered security stack including ZTNA, secure web gateway (SWG), cloud access security broker (CASB), and firewall-as-a-service (FWaaS), all enforced at Points-of-Presence located close to your users rather than backhauled through a legacy data-centre firewall. Every connection undergoes per-request verification of user identity, device posture, and resource authorisation — eliminating the implicit trust that VPN-based remote access grants. Our 24x7 SOC correlates telemetry across network, endpoint, and cloud layers, executing automated incident playbooks that isolate compromised hosts before lateral movement propagates. The result is a lower TCO estate with unified policy management across all edges, materially reduced attack surface, and a single accountable operational partner instead of a stack of vendor-specific management consoles.
Capabilities
What's included as part of this solution.
SD-WAN
Application-aware traffic steering across diverse underlay transports — Internet, Broadband, MPLS and LTE — using real-time SLA measurement per flow. Each application class receives the path that meets its latency, jitter, and loss tolerance. New sites bootstrap with zero-touch provisioning: pre-staged edge appliances authenticate to the controller, download policy, and join the fabric without onsite engineering.
- Per-application SLA monitoring and dynamic path steering
- Zero-touch provisioning for site onboarding
- Centralised policy orchestration across all edge nodes
SASE & SSE
Converged secure access architecture: SD-WAN integrated with cloud-delivered security services — ZTNA, SWG, CASB, and FWaaS — enforced at global Points-of-Presence close to users. SSE delivers the security stack independently where WAN overlay is already handled; together with SD-WAN they form a full SASE framework with a single policy plane.
- Zero-trust network access (ZTNA) with identity-aware proxying
- Secure web gateway (SWG) with TLS inspection and CASB integration
- Cloud-delivered FWaaS at the network edge
Managed Detection & Response
A 24x7 SOC that analyses correlated telemetry across network flows, endpoint events, and cloud audit logs. When a detection fires, automated containment playbooks isolate the compromised host at the network edge — before lateral movement can reach domain controllers or shared storage. Incident reports provide root-cause analysis in business language, not raw SIEM output.
- 24x7 SOC with tiered triage and escalation workflows
- Automated host and network containment at detection time
- Root-cause incident reporting in business-operational language
Zero-Trust Access
Identity-aware, least-privilege access brokered through a reverse proxy that authenticates every request against IdP assertion, device compliance, and resource policy. Unlike VPN-based models where a single connection grants LAN-level access, ZTNA exposes only the specific application a role is authorised to reach — rendering a stolen credential ineffective beyond its scoped resource.
- Per-request identity verification regardless of source location
- Device posture assessment (patch, AV, disk encryption) at connect time
- Application-level least-privilege access with session recording
Resilience & Recovery
Immutable, air-gapped backup storage with versioning and write-once-read-many (WORM) protection, paired with regularly tested restore runbooks. A ransomware event that encrypts production volumes becomes a recovery operation rather than a data-loss incident, because an untested backup is a contingency narrative, not an operational control.
- Immutable and logically air-gapped backup repositories
- Scheduled, documented restore rehearsals with recovery-time verification
- Ransomware-resilient architecture by storage-layer design
Where it's used
Real-world scenarios where this solution delivers measurable outcomes.
Cut WAN cost without losing control
Shift bulk internet traffic onto commodity broadband and LTE/5G underlays while MPLS continues to carry latency-sensitive ERP and VoIP flows. You reduce per-Mbps WAN cost by routing around expensive private circuits where application tolerance permits, and SD-WAN's real-time path selection ensures each application class receives its required SLA without manual reconfiguration.
Stop a breach at the endpoint
A user workstation executes a payload from a phishing attachment. The endpoint EDR agent flags anomalous process behaviour, our SOC correlates the alert with network telemetry and validates within minutes, and the switch port is administratively disabled via automated playbook — the blast radius is contained to a single machine before any lateral movement toward file shares or domain controllers begins.
Make hybrid work actually secure
Office, home, and mobile users all authenticate through the same identity-aware proxy with device posture enforcement. A user connects to the specific SaaS or internal application their role requires — not the entire LAN behind a VPN tunnel — eliminating the overly permissive access surface that attackers routinely exploit in hybrid-work deployments.
Frequently asked questions
Will SD-WAN replace our MPLS?
SD-WAN typically augments MPLS rather than replacing it entirely. We steer commodity traffic to lower-cost broadband and LTE/5G underlays while keeping latency-sensitive flows on MPLS paths. Full MPLS replacement occurs only where the TCO case for your specific application profile and site topology justifies it.
Do you run a SOC, or just sell us tools?
We operate a managed detection and response service — SOC-grade analysis, triage, and automated containment around the clock. You receive the outcome of security operations (detected threats, contained incidents, root-cause reports), not a console you must staff and operate yourself.
Do we have to rip out our existing network?
No. We deploy SD-WAN overlays and zero-trust controls on top of your existing circuits and edge hardware where they meet minimum performance and security baselines. Transformation is staged site-by-site according to your risk priority, not executed as a single big-bang cutover.
What is the difference between SASE and SSE?
SASE is the full converged model: SD-WAN plus cloud-delivered security (ZTNA, SWG, CASB, FWaaS). SSE is the security-only component — all the cloud security controls without the SD-WAN overlay. If your WAN routing is already adequate, SSE still delivers the zero-trust architecture without requiring a WAN redesign.
How fast can a new branch go live securely?
With zero-touch provisioning, a pre-staged edge appliance activates within minutes of power-on — automatically pulling SD-WAN configuration, security policies, and ZTNA rules from the orchestrator — so the new site operates at production security posture from hour one rather than being secured in a follow-up change window.
Why choose Clevertek for Secure Network Transformation
One accountable partner for end-to-end solutions — here is what buying from us actually gets you.
Vendor-agnostic by design
We select the SD-WAN edge platform and SASE security stack that fits your existing infrastructure and risk posture, not one dictated by a single OEM partnership. You get the right architecture for your estate, not a sales quota fulfilment.
Defense in depth, not a point product
SD-WAN, SASE, ZTNA, and live SOC operations layer into a single managed program. No individual control bears the entire security burden, and no single configuration gap represents a catastrophic exposure.
Assume-breach mindset
We design every control on the assumption that an attacker is already inside the perimeter. Per-request verification and least-privilege grants mean a compromised credential accesses only the specific resource it was authorised for at that moment.
One program, one SLA
Network and security delivered, integrated, and operated under a single service agreement. When an incident occurs, you make one call — not three separate vendor support tickets.
