Over the Top SD-WAN for Flexible, Cost-Efficient Network Performance
Add application-aware routing and cloud optimization—without disrupting your existing firewalls or security tools.
What Is Over the Top (OTT) SD-WAN, and Why It Matters
Smarter routing, delivered as a seamless overlay.
Over-the-top (OTT) SD-WAN refers to software-defined networking delivered over existing internet connections without embedded firewalls or security functions. It’s ideal for businesses that already have a firewall or prefer to manage security through a separate stack, such as SASE or NGFW appliances.
OTT SD-WAN offers the performance benefits of SD-WAN—like dynamic path selection, QoS, and cloud optimization—without replacing your current network security. At TeleSwitch, we help you evaluate lightweight SD-WAN solutions that integrate cleanly into your existing architecture.
What You Gain with an OTT SD-WAN
Cloud-ready performance. Simplified deployment.
Application-aware routing without disrupting firewalls
Reduced latency and jitter for cloud-based apps
Bandwidth optimization across the internet and MPLS
Zero-touch deployment and centralized control
Works with any ISP—no need to change providers
How Businesses Are Using OTT SD-WAN Today
Enhancing performance, preserving security investments.
Adding SD-WAN functionality to MPLS/broadband hybrid environments
Improving voice/video quality for UCaaS and collaboration tools
Supporting secure cloud migrations without re-architecting the edge
Enhancing remote site performance where a firewall is already in place
Deploying SD-WAN on top of broadband for small or temporary locations
The Strategic Value of Expert Guidance
Not all SD-WAN overlays are built the same.
Some providers focus on app routing, others on cloud interconnects or integration with existing firewalls. Features like packet duplication, FEC (forward error correction), or virtual appliance support may be unavailable.
At TeleSwitch, we help you cut through the noise by identifying the right OTT SD-WAN solution for your current stack, cloud strategy, and performance requirements.

Frequently Asked Questions
Understand the flexibility of Over the Top SD-WAN
Can OTT SD-WAN work with our existing firewall?
Yes. That’s precisely the point. It overlays onto your existing edge infrastructure without conflict.
Is this cloud-managed?
Most OTT SD-WAN platforms offer cloud-based portals for policy control, monitoring, and reporting.
Do we need to replace our circuits?
Not at all. With complete ISP flexibility, OTT SD-WAN works over broadband, DIA, LTE/5G, or MPLS.
How does this help with cloud apps like Microsoft 365 or Salesforce?
OTT SD-WAN can dynamically prioritize and route cloud traffic, improving speed and user experience.
Is this a good fit for small or remote sites?
Yes. It’s an ideal way to extend intelligent routing to remote offices without adding full security stacks.
