Tired of expensive SIEMs that don't understand firewall logs?
FLASI is a full-featured analytics platform that transforms Fortinet (FortiGate, FortiEDR, FortiMail, FortiWeb) and Palo Alto PAN-OS logs into actionable threat intelligence without breaking the bank.
After 10+ years fighting with overpriced SIEMs that treat firewall logs as an leftover checkbox in a datasheet, we built the platform we always needed.
No sampling. No filtering. Full visibility. Full behavioral analysis.
Traditional SIEMs force you to choose:
- Option A: Log everything → Go bankrupt from licensing costs
- Option B: Sample/filter logs → Miss threats hiding in the gaps
We chose Option C: Build a platform optimized specifically for high-volume firewall logs using modern, cost-effective tech.
Built by security analysts, for security analysts
- Full field parsing - Every field from Fortinet and Palo Alto logs, not just the "important" ones
- ECS standardization - Translates to Elastic Common Schema
- Rich enrichment - GeoIP, network community ID, registered domains, threat intel integration
- Purpose-built dashboards for threat hunting (Kibana & Grafana)
- Behavioral analysis - Detect slow burns, lateral movement, beaconing
- No other tool (paid or free) has this depth of firewall log analysis
- One-script deployment for Elasticsearch components
- Pre-configured pipelines for Vector and Elastic Agent
- Production-ready dashboards on day one
- No vendor lock-in - swap components as needed
Fortinet/Palo Alto → Vector/Elastic Agent → Elasticsearch/Victoria Logs → Kibana/Grafana
Mix and match: Every layer is swappable. Use what works for your environment.
