Introduction to “cisco-ftd.7.2.8.25.SPA.csp” Software
cisco-ftd.7.2.8.25.SPA.csp is the core software image for Cisco Firepower 4100/9300 series appliances and Secure Firewall 3100/4200 platforms, delivering unified threat prevention with TLS 1.3 inspection capabilities. Released in Q1 2025 under Cisco Security Advisory CSCvp77466, this version introduces Zero Trust Network Access (ZTNA) integration with Duo Security and hardware-accelerated cryptojacking detection.
The image supports 200Gbps threat prevention throughput on Firepower 9300 chassis with Catalyst 9800 Wireless Controller integration, making it ideal for large-scale enterprise network perimeters. It addresses critical vulnerabilities in SSL/TLS session handling identified in previous FTD 7.2.x releases while maintaining stateful failover continuity.
Key Features and Improvements
This release introduces mission-critical enhancements for modern security operations:
-
Advanced Threat Prevention
- Implements Snort 3.1.8 with 40% faster HTTP/3 traffic normalization
- Adds machine learning-driven cryptojacking detection via NPU telemetry analysis
-
Zero Trust Enforcement
- Integrates Duo Beyond Identity for continuous device posture validation
- Enables microsegmentation policies using Cisco TrustSec security group tags
-
Performance Optimization
- Achieves 200μs latency for encrypted traffic inspection using FPGA-accelerated AES-GCM
- Supports 150,000 concurrent TLS 1.3 sessions per security module
-
Management Enhancements
- Introduces REST API endpoints for bulk security zone migration
- Adds Dark Mode support in Firepower Management Center 7.2.8 web interface
