- ✓ Monetized Parental Control & Safe Search add-on packages for subscribers
Access Control List (ACL) Hardware & Software Engine
Micro-segmented traffic filtering based on IP 5-tuple, protocol flags, subscriber VLANs, and application signatures.
- ✓ Defend carrier edge infrastructure against port scans and probe botnets
- ✓ Subscriber-specific ACLs dynamically assigned via RADIUS Access-Accept
- ✓ Time-of-day access schedules (e.g., enterprise office hours vs weekend rules)
Lawful Interception (LI) Gateway & ETSI Mediation
Statutory interception mediation device compliant with ETSI TS 102 232, CALEA, and international telecommunications law enforcement standards.
- ✓ Undetectable target monitoring: zero latency deviation on target session
- ✓ Hardware-isolated administrative enclave with dual-custody access keys
- ✓ Real-time streaming handover of raw PCAP payload over encrypted TLS tunnels
Mini-Firewall & Edge Subscriber Protection
Cloud-managed subscriber perimeter security: blocking incoming scans, malicious botnet command-and-control, and brute-force vectors.
- ✓ Inbound shield: stops Mirai and Dark IoT botnet probing dead in the water
- ✓ Subscriber self-service portal: toggle protection levels via ISP mobile app
- ✓ Monetized Value-Added Service: recurring $1-$3/month ISP revenue stream
Software-Based BRAS / BNG (Broadband Network Gateway)
High-density carrier subscriber termination supporting dual-stack IPoE (DHCP/Option 82) and PPPoE with full RADIUS/CoA integration.
- ✓ DHCP Option 82 parsing for precise physical switch port identification
- ✓ Dynamic captive portal redirection for unpaid or grace-period accounts
- ✓ 90% reduction in hardware CAPEX vs legacy ASIC network chassis
CG-NAT (Carrier-Grade NAT & IPv6 Migration)
Massive-scale NAT44, CGN deterministic port mapping, Full-Cone NAT, and DS-Lite for smooth IPv4 conservation and IPv6 transition.
- ✓ Deterministic port allocation: zero database logging overhead
- ✓ Eliminates strict NAT warnings for Sony PlayStation & Xbox Live users
- ✓ Linear scaling across CPU cores via DPDK lock-free hash tables
Carrier-Grade AntiDDoS Protection
Real-time volumetric flood mitigation, SYN cookie validation, and DNS amplification defense directly in the carrier data path.
- ✓ Automatic signature generation for zero-day multi-vector attacks
- ✓ Scrubbing-as-a-Service: ISPs can resell clean-pipe protection to corporate clients
- ✓ Zero packet drop on legitimate subscriber traffic during active mitigation
QoE Analytics (Quality of Experience Intelligence)
Deep telemetry into network latency, TCP retransmissions, video buffering, and subscriber churn risk scored across ClickHouse databases.
- ✓ Automated Churn Predictor: flags subscribers experiencing repeated latency spikes
- ✓ CDN Peering Optimization: identifies which transit peering partners drop packets
- ✓ Marketing Upsell Engine: pinpoints power users ready for higher tier broadband plans
PGW (Packet Data Network Gateway for LTE/5G & MVNOs)
3GPP compliant Packet Gateway terminating S5/S8 GTP tunnels, allocating mobile subscriber IP addresses, and enforcing QoS/Charging.
- ✓ Built-in Header Enrichment: injects MSISDN/IMSI headers into HTTP sessions
- ✓ Zero-overhead charging: diameter Gy credit-control for real-time prepaid airtime billing
- ✓ Ideal for MVNO rollouts: complete mobile packet core in a compact footprint
PCEF (Policy & Charging Enforcement Function)
Carrier policy execution node communicating over 3GPP Diameter Gx & Gy interfaces for zero-rated traffic, throttling, and prepaid credit control.
- ✓ Zero-rating enforcement: exempts WhatsApp, Facebook, or mVAS portals from data quotas
- ✓ Instant quota exhaustion cutoff: eliminates carrier bill-shock complaints
- ✓ Seamless integration with Direct Carrier Billing (DCB) subscription engines
ePDG (Evolved Packet Data Gateway for VoWiFi)
Secure IPsec gateway connecting untrusted non-3GPP networks (Wi-Fi) to the mobile packet core for seamless Voice over Wi-Fi (VoWiFi).
- ✓ Indoor cellular blackspot elimination: route voice calls over domestic broadband
- ✓ Zero subscriber app required: native iOS and Android Wi-Fi Calling integration
- ✓ Seamless VoWiFi to VoLTE call handover without voice dropping
PCRF Proxy & Diameter Routing Agent (DRA)
High-availability Diameter load balancer, session binding router, and policy offload engine for telecom networks.
- ✓ Prevents signaling collapse during major network events and SIM re-registration
- ✓ Multi-vendor mediation: translates proprietary vendor Diameter AVPs seamlessly
- ✓ Cuts PCRF software licensing costs by up to 45% through query offload
LBS (Location-Based Services & Cell-ID Positioning)
Carrier cell-tower triangulation, Cell-ID resolution, and proximity-targeted marketing engine for telecom operators and enterprise partners.

- ✓ Fraud prevention: verify whether credit card or DCB transactions match user phone location
- ✓ Emergency regulatory compliance for public safety answering points (PSAPs)
Break Free from Multi-Million Dollar Proprietary ASIC Chassis
Legacy telecom equipment vendors lock operators into proprietary hardware with expensive annual software subscriptions. Stingray Service Gateway delivers equivalent or superior wire-speed performance on standard high-volume servers from Dell, HP, Lenovo, Supermicro, or ITPOD.
