The record

Purpose: StormWall Appliance is on-premises DDoS protection software that processes network traffic locally on customer hardware.
Filtering: It provides multi-layer DDoS filtering at OSI layers 3–5, including protection for VPN, SIP, DNS, QUIC, and TLS JA3 traffic.
Attack coverage: The product lists protection against volumetric floods, TCP floods, DNS attacks, UDP reflection and amplification, fragmentation, and attacks on gaming and VoIP services.
Encrypted traffic: StormWall says it filters attacks in TLS and QUIC traffic without decryption.
Integrations: The product includes a REST API for external integrations and can work alongside StormWall cloud protection for L7 protection such as HTTP Flood, Slow HTTP, and WAF.
Analytics: The listed capabilities include traffic capture and analysis with PCAP, customizable dashboards, and metrics.
Deployment: It runs as software on customer-owned physical or virtual servers, and StormWall says standard compatible x86 platforms are sufficient.
Data locality: StormWall says traffic is processed locally and does not leave the customer's perimeter; offline licensing with a hardware key is available for isolated networks without internet access.
Compatibility: StormWall recommends internally tested hardware platforms and says it assesses compatibility individually for other platforms.
Trial: A free 30-day trial can run on the customer's own real traffic after deployment.
Capacity limit: The listed starting configuration is 10 Gbps, and StormWall says high-volume attack peaks that exceed the channel bandwidth are handled by its cloud protection.
Customer fit: The product page describes Basic support as suitable for teams with in-house information-security expertise and Private support as an option for teams without in-house DDoS expertise.
Maker: StormWall describes itself as a cybersecurity-as-a-service provider protecting IT infrastructures of any size and complexity.
