Stormshield SN3100 vs TEHTRIS XDR/DNS Firewall: Side-by-Side Comparison (2026)

Short answer

Enterprise security teams defending geographically distributed critical infrastructure will benefit most from SN3100's ability to sustain 74 Gbps firewall throughput and 55 Gbps IPS inspection without degradation, paired with support for 5,000 IPSec tunnels and 5 million concurrent sessions. The Visa de sécurité certification and Common Criteria validation matter here; this is built for regulated environments where auditors care about pedigree. Skip this if your priority is cloud-native workloads or if you need tight integration with SIEM; SN3100 emphasizes network perimeter hardening over the detection and response instrumentation that modern incident response demands. Security teams in mid-market and enterprise organizations that treat DNS as a detection layer, not just a choke point, should evaluate TEHTRIS XDR/DNS Firewall. The platform's DGA detection and newly created domain blocking catch threats before they phone home, and integration with TEHTRIS' SOAR capabilities means you can automate response without writing code. This tool prioritizes detection and mitigation over forensic depth; if your primary need is post-incident investigation and evidence retention, you'll want stronger logging than DNS-only visibility provides.
