- Addresses 14 CVEs rated 7.8+ CVSS, including:
- CVE-2025-0421: Buffer overflow in SSL-VPN portal customization (CVSS 9.3)
- CVE-2025-0422: Improper certificate validation in SD-WAN orchestrator (CVSS 8.7)
2. Performance Optimization
- 22% faster IPSec VPN tunnel establishment through enhanced ASIC offloading
- 18% reduction in memory consumption during concurrent UTM inspections
3. Enhanced Protocol Support
- Full TLS 1.3 Suite B compliance for government sector deployments
- Extended RADIUS attribute support for PCI-DSS 4.0 compliance audits
4. Hardware Longevity
