SDN vendors and buyer guide

SDN software enables centralized control and automation of network infrastructure, improving agility and security.

SDN solutions help organizations overcome the limitations of traditional hardware-centric networks by decoupling the control and data planes. This allows for programmable, policy-driven network management, enhancing security, reducing operational costs, and accelerating digital transformation.

What is the best way to evaluate SDN vendors?

Start with the business outcome, required capabilities, implementation risk, and evidence from comparable buyers. Palomarr helps buyers compare SDN vendors across fit signals, procurement guidance, and related buyer guides so the shortlist is built around need instead of brand familiarity.

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.

Questions to ask suppliers

Use these questions during supplier evaluations to ensure you're choosing the right partner for your needs.

SDN RFP guide
  • How does your controller handle failover scenarios to maintain network uptime during a DDoS attack?
  • What specific out-of-the-box integrations do you offer for ServiceNow and Okta?
  • What is the typical implementation timeline for a 50-branch enterprise network?
  • How do you ensure compliance with PCI-DSS and HIPAA regulations in a hybrid-cloud environment?
