Securing the Modern Enterprise by Eliminating 23 Critical Points of Network Failure
Author: Ron Lovern
First Published: March 2019
Customer Profile
- Organization Type: Mid-to-large enterprise
- Environment: Hybrid workforce (on-site, remote, mobile users)
- IT Landscape: LAN, WAN, cloud applications, collaboration platforms
- Primary Concern: Increasing cybersecurity risk and lack of visibility across the network
Business Challenge
As digital transformation accelerates, organizations face an expanding attack surface driven by cloud adoption, remote work, and distributed applications. Traditional, single-site, hierarchical network designs no longer provide adequate visibility, control, or security.
The customer was experiencing:
- Limited end-to-end visibility across LAN, WAN, and cloud environments
- Increased exposure to cyber threats across multiple unmanaged access points
- Fragmented communication and collaboration platforms
- Difficulty managing security consistently for remote and mobile employees
- Growing risk of business disruption due to unaddressed points of failure
Daily cyberattacks and the decentralization of IT resources made it clear that existing security models were no longer sufficient.
Solution Overview
The organization adopted an End-to-End Network and Communication Security Framework designed to identify, manage, and mitigate 23 distinct points of failure across the enterprise network.
The solution focused on:
- A holistic, end-to-end view of the entire communication stack
- Integrated security across LAN, WAN, and Virtual (Cloud/Application) environments
- Cloud-based, managed network security services
- Real-time threat protection and monitoring
- Secure enablement of collaboration, mobility, and remote access
Rather than treating security as a perimeter-only function, the framework extended protection beyond the firewall, ensuring visibility and control across all users, devices, and applications.
Architecture & Key Components
- Endpoint access control
- Internal traffic monitoring
- Segmentation to limit lateral movement
- Secure connectivity between sites
- Encrypted traffic flows
- Centralized policy enforcement
- Application-level protection
- Secure access to cloud services
- Visibility into collaboration and business intelligence platforms
- End-to-end visibility of the communication framework
- Actionable data for proactive network management
- Unified control across physical and virtual environments
Business Outcomes
By addressing all 23 potential points of failure, the organization achieved:
- Reduced Security Risk: Minimized exposure to network breaches across all environments
- Improved Visibility: Full end-to-end insight into network and communication flows
- Stronger Business Continuity: Security embedded into daily operations and disaster recovery planning
- Workforce Enablement: Secure, seamless connectivity for remote and mobile employees
- Operational Efficiency: Simplified management of a complex, distributed network
Key Value Delivered
- Security aligned with modern digital transformation initiatives
- A resilient, agile IT foundation supporting data-driven business operations
- Protection designed for today’s collaboration-heavy, cloud-first workforce
- A scalable framework that evolves with technology and business growth
Conclusion
As businesses become more distributed and cloud-dependent, addressing security gaps in isolation is no longer effective. This use case demonstrates how an end-to-end network security strategy, built around identifying and mitigating 23 critical points of failure, enables organizations to protect their networks, empower their workforce, and sustain growth in an increasingly hostile threat environment.
