The challenge
Your organization faces increasing complexity and sophisticated cyber threats with a traditional networking environment. Manual configuration of firewalls and routers is slow and error-prone, leading to security breaches and operational inefficiencies. The lack of centralized policy management hinders agility and makes it difficult to respond to changing business needs. The rise of east-west threats exacerbates the problem, as attackers move laterally within your network, bypassing perimeter defenses. You need a solution that simplifies network management, enhances security, and enables faster innovation.

The solution
SDN addresses your unique challenges through modern solutions and key capabilities.
Automated micro-segmentation
Isolates individual workloads based on identity, creating a Zero Trust architecture that limits lateral movement of threats and reduces the attack surface.
Centralized multi-cloud orchestration
Provides a single pane of glass for managing networking policies across AWS, Azure, Google Cloud, and on-premises data centers, simplifying hybrid cloud management.
Real-time telemetry and analytics
Monitors every packet flow, identifying anomalies and potential exfiltration in real-time, enabling proactive threat detection and response.
Intent-based automation (IBN)
Interprets high-level business rules and automatically configures the underlying network fabric, reducing manual configuration errors and improving agility.
Seamless SASE integration
Converges networking (SD-WAN) and security (Firewall-as-a-Service, Secure Web Gateway) into a single, cloud-delivered platform for comprehensive protection.
Open API architecture
Integrates with third-party security tools, ITSM platforms, and custom business applications, enabling a flexible and extensible network infrastructure.

How to evaluate SDN
1
Deployment versatility
Evaluate whether the vendor requires a complete hardware replacement (Greenfield) or can operate as an overlay on your existing infrastructure for cost-effectiveness.
2
Total cost of ownership (TCO)
Account for personnel costs associated with training engineers on Python and APIs, as these can significantly impact the overall TCO.
3
Integration with existing ecosystems
Ensure the SDN controller natively connects with your organization's ITSM, identity providers, and existing security tools for maximum ROI.
4
Vendor stability and innovation roadmap
Consider the vendor's financial health and R&D investment in AI and automation, consulting Gartner Magic Quadrant reports for SASE and SD-WAN.
