ACL Digital Helped a Leading U.S. Telecom Provider Deliver Enterprise-Grade Zero Trust Security for a Distributed Workforces
Overview
The shift to permanent remote and hybrid work eliminated the traditional corporate security perimeter, rendering standard VPN-based models inadequate and increasingly dangerous. A leading U.S. telecommunications provider identified an urgent market demand for end-to-end security capable of protecting distributed workforces across untrusted environments, from user devices through to private data centers and public clouds. ACL Digital was engaged as a specialized systems integrator to design, deploy, and manage a comprehensive SASE (Secure Access Service Edge) and Zero Trust Network Access (ZTNA) platform, integrating advanced security capabilities across a complex, multi-tenant enterprise environment.

Challenges
Collapse of the traditional perimeter
Permanent remote work rendered the conventional office-perimeter security model obsolete, exposing enterprises to significant vulnerabilities that standard VPNs could not adequately address
Static trust models at scale
Existing security frameworks granted broad network access based on physical location rather than continuous contextual evaluation, creating dangerous blind spots across distributed environments
Multi-layered integration complexity
Delivering a unified security fabric required seamlessly bridging enterprise ordering portals, network control planes, and premium third-party vendor platforms within a single cohesive architecture
Solution
ACL Digital designed and deployed an enterprise-grade SASE security platform built around a strict Zero Trust model:
- Versa SASE gateway integration: The solution integrates directly with the Versa SASE gateway, combining advanced software-defined routing with multi-tenant cloud security enforcement.
- Zero Trust Network Access enforcement: Operating on a “never trust, always verify” principle, every connection, regardless of origin, is continuously evaluated across identity verification, device compliance checks, and contextual geography assessment. Connections originating from embargoed or high-risk regions are automatically dropped at the gateway.
- Granular application-level access: Verified users are granted profile-restricted routing to specific resources only, keeping the remainder of the corporate infrastructure entirely invisible and inaccessible.
- Cloud Access Security Broker (CASB): Inline policy rules enforce highly granular data controls, for example, permitting a user to upload files to a cloud repository while simultaneously blocking downloads, directly preventing data exfiltration.
- Advanced Threat Protection (ATP): Suspicious web traffic is dynamically isolated into a virtual sandbox, where behavioral data is inspected in real time to identify and block malware or ransomware payloads before they reach the endpoint.
Outcomes
- True end-to-end security: Enterprise clients achieved a unified security fabric protecting distributed data assets across diverse, untrusted remote environments, eliminating the vulnerabilities of legacy perimeter models
- Proactive threat mitigation: Integrated CASB and ATP capabilities enable enterprises to stop insider data exfiltration and external malware or ransomware threats at the gateway layer before they cause damage
- Proven systems integration expertise: ACL Digital demonstrated deep capability as a primary SASE systems integrator, bridging enterprise portals, network control planes, and premium vendor platforms into a single, cohesive deployment
- Positioned for a high-growth market: SASE and Zero Trust represent among the fastest-growing segments in enterprise cybersecurity, making this engagement a strong reference for organizations evaluating distributed workforce security platforms
