About the Cisco Secure Firewall 3105 Appliance
The Cisco Secure Firewall 3105 is the entry-level appliance in the Secure Firewall 3100 series, introduced in Q2 2025 to deliver enterprise-grade threat defense performance at a scale appropriate for mid-market organizations. The appliance is powered by a dedicated security processor architecture that offloads TLS 1.3 decryption and re-encryption from the main CPU, eliminating the dramatic throughput degradation that plagues software-only inspection engines when handling encrypted traffic. This hardware acceleration ensures that organizations can enforce full deep packet inspection across HTTPS, SMTPS, and other TLS-wrapped protocols without compromising network latency or application user experience.
Ideal for
- Mid-market enterprise perimeter firewall replacing end-of-life Cisco ASA 5500-X or third-party legacy next-generation firewalls with modern TLS 1.3 inspection capabilities
- Encrypted traffic inspection at branch office WAN edges where software-based decryption would saturate CPU resources and degrade throughput for latency-sensitive applications
- Remote access VPN gateway for distributed workforces using Cisco Secure Client with multi-factor authentication and posture assessment enforced at the firewall policy level
- Microsegmentation enforcement point within campus or data center networks, applying application-layer policy between internal VLANs and east-west traffic flows
- Compliance-driven environments requiring continuous IPS, URL filtering, and malware inspection to satisfy PCI DSS, HIPAA, and NIST CSF control frameworks
- Cloud-on-ramp security gateway for hybrid architectures connecting on-premises infrastructure to public cloud providers via encrypted SD-WAN or dedicated interconnects
