GridM BNG vs VAS Experts Stingray SG

VAS Experts Stingray Service Gateway (SSG) is a DPI-centric traffic control platform that also provides BRAS/BNG and CGNAT functions on x86. This comparison looks at what changes when the subscriber edge is a purpose-built BNG rather than one function of a DPI service gateway.

Why operators choose GridM

  • A purpose-built subscriber edge: one plan with every BNG feature, priced per subscriber, not by bandwidth tier or option pack
  • N+1 clusters with session sync and hitless failover for the subscriber edge
  • IPDR search, a legal-request workflow and a scoped LEA role built in for lawful compliance
  • One central web console for the whole cluster, with DDoS protection and flow analytics included

Where VAS Experts shines

Stingray SG is built around a strong in-house DPI engine that classifies thousands of applications, with QoE analytics, traffic prioritization and filtering, Full Cone CGNAT and a management GUI, and it scales to very high throughput per server. If DPI-driven services are the goal, it is a purpose-built platform.

We believe in honest comparisons. Pick what fits your network; when the criteria are cost per subscriber, automation and freedom from lock-in, we are confident in GridM.

The verdict

If your strategy centers on DPI, meaning application classification, QoE analytics, filtering and traffic-driven services, Stingray SG is built for exactly that, with BNG and CGNAT alongside. If what you need is a carrier-grade software BNG with clustering, built-in DDoS, analytics and compliance on a simple per-subscriber plan, GridM BNG is the purpose-built choice, and it can sit next to a DPI platform if you run one.

FAQ

Switching from VAS Experts Stingray SG: your questions

For the BNG/BRAS role, yes. GridM BNG terminates PPPoE and IPoE subscribers, enforces per-plan QoS, speaks RADIUS with CoA and provides CGNAT and dual-stack IPv6, the functions operators deploy VAS Experts Stingray SG for at the broadband edge. Routing and other roles VAS Experts platforms may also serve are evaluated separately in your design.
