Overview
For modern businesses, network infrastructure is no longer merely a means of connectivity; it is a strategic resource that creates competitive advantage. The spread of cloud applications, the permanence of remote working models and the growth of IoT devices have fundamentally transformed the demands placed on enterprise networks. Indexline Network & Communication Solutions offer a comprehensive approach to managing this transformation smoothly.
In enterprise LAN/WAN design, keeping performance, security and cost in balance is critical. The Indexline team designs customized network architectures by analyzing each organization's traffic profile, application requirements and growth objectives. All network layers, from campus networks to branch integrations and from data center interconnects to cloud access points, are addressed within this holistic architectural framework.
SD-WAN technology removes the cost and flexibility constraints of traditional WAN architectures. Thanks to centralized policy management, traffic flows across thousands of branch locations are dynamically optimized according to application priorities and bandwidth usage. By making smart use of broadband internet connections alongside expensive MPLS lines, costs come down while redundancy goes up. Indexline delivers services with a team of certified experts on the Cisco Viptela, VMware VeloCloud and Fortinet SD-WAN platforms.
Network security cannot be considered separately from infrastructure design. Next-Generation Firewall (NGFW) solutions, IPS/IDS systems and network segmentation policies are designed as integral parts of the network infrastructure. In networks designed according to Zero Trust network architecture principles, every connection point goes through authentication and authorization. This approach provides effective protection against a broad range of threats, from insider threats to external attacks.
How It Works
Network Discovery and Traffic Analysis: The existing network infrastructure is comprehensively mapped. Traffic patterns, bandwidth utilization, latency and loss values are measured. This data forms the basis for design decisions.
Architecture Design and Selection: The network architecture and hardware/software components best suited to the organization's needs are determined. Layered network design, redundancy requirements and security policies are designed in parallel.
Pilot Deployment: Before going live in critical production, a pilot installation is carried out in a limited environment. Performance, reliability and security tests are completed at this stage.
Phased Migration: The move to the production environment is carried out according to a phased plan that minimizes business disruption. Rollback procedures are kept ready before each phase.
QoS Configuration: Quality of Service policies that prioritize critical applications (ERP, VoIP, video conferencing) are applied. Bandwidth guarantee and limiting rules are activated.
Security Integration: NGFW rules, IPS signatures, URL filtering and application control are configured. Network segmentation and microsegmentation are applied.
Monitoring and Continuous Optimization: Network performance is monitored 24/7. When capacity thresholds are approached, proactive alerts are generated and configuration changes are recommended.

The Indexline Approach
What sets Indexline's network solutions apart is a security approach that begins at the design stage. Following the "Security by design" principle, every security layer is built into the network architecture from the outset; security is treated not as a feature added later but as a fundamental design component.
Our Cisco Gold Partner status provides early access to the latest networking technologies and a direct line to Cisco TAC (Technical Assistance Center). This status directly affects the quality of the technical support we provide to our customers and the time to resolution. We maintain equally close partnerships with security-focused partners such as Fortinet and Palo Alto Networks.
In every network project, we never lose sight of economic realism. The designed solution must be implementable within your organization's budget cycle, allow for capacity planning and be deliverable in phases when needed. That is why we design large network projects with modular architectures, offering the flexibility to spread investment costs over time.
Frequently Asked Questions
Can we use SD-WAN without removing our existing MPLS infrastructure?
Yes, SD-WAN can be deployed in hybrid mode. Your existing MPLS lines are included in the connection pool managed by SD-WAN, and broadband lines are added to the same pool. This keeps MPLS's guaranteed quality for critical applications while using low-cost broadband for internet traffic. Cost optimization is achieved as decisions are made to gradually reduce MPLS lines.
Up to how many branch locations can you manage with SD-WAN?
Enterprise SD-WAN platforms such as Cisco Viptela and VMware VeloCloud can bring thousands of branch locations under central management. Our references include financial institutions with 500+ branches. Scalability is planned according to the chosen platform and licensing model.
How is business continuity maintained during network changes?
All network changes are planned and implemented in accordance with change management procedures. Critical changes are carried out during maintenance windows when business activity is low. A rollback procedure is prepared and tested before every change. Thanks to configuration management tools, any change can be reversed within minutes.
What is the difference between an NGFW and a traditional firewall?
Traditional firewalls inspect traffic based on IP addresses and port numbers. An NGFW, by contrast, offers visibility down to the application layer: it tracks which user is using which application and at what time. With integrated IPS, URL filtering, inspection of SSL-encrypted traffic and threat intelligence feeds, it provides far more comprehensive threat protection.
Is Wi-Fi infrastructure included in your projects?
Yes. Campus Wi-Fi design, central controller installation, comprehensive coverage analysis (site survey) and RF optimization are part of our service portfolio. We have certified experts on the Cisco Meraki, Aruba and Ruckus platforms.
Do you use artificial intelligence/machine learning in network infrastructure?
Yes. AI/ML-based anomaly detection and proactive troubleshooting are becoming increasingly common in modern network management platforms. AI-driven platforms such as Cisco DNA Center and Juniper Mist automatically detect abnormal traffic patterns and accelerate root cause analysis. Evaluating and integrating these technologies is also part of our services.
Do you offer network audit services?
Yes, we carry out comprehensive security and performance audits of your existing network infrastructure. The audit report includes the vulnerabilities identified, improvement recommendations and a prioritization. This report contributes directly to your budget planning and project prioritization processes.
What do you recommend for remote working infrastructure?
For modern remote working infrastructure, we evaluate SSL-VPN or ZTNA (Zero Trust Network Access) solutions. ZTNA offers more granular access control and a better user experience than traditional VPN. MFA integration and device compliance verification are standard in both solutions.
