In today’s digital landscape, network security is more crucial than ever for organizations of all sizes. Cisco’s Secure Firewall product line, designed to address these needs, provides robust, next-generation firewall solutions that ensure seamless protection for enterprise branch offices, while maintaining full visibility of attack surfaces and comprehensive threat protection.
Cisco Secure Firewall offers an integrated, compact solution that goes beyond traditional security measures. By leveraging the industry’s first Encrypted Visibility Engine (EVE) and an Intrusion Prevention System (IPS) powered by Snort 3, this firewall enables defense against both known and emerging threats, even within encrypted traffic. This comprehensive visibility and control is part of Cisco's larger vision for a platform-driven security approach. The goal is to create a coordinated, agile, and automated security ecosystem that spans architectures, regions, and tenants.
Cisco Secure Firewall: A Leader in Network Security
Cisco has earned a prominent position in the cybersecurity landscape. According to the Forrester Wave™ 2024 Q4 Enterprise Firewall Solutions report, Cisco is recognized as a leader, receiving top scores across 15 criteria, including policy creation and management, traffic encryption and decryption, IDS/IPS, DNS security, and threat intelligence. Among its standout features are SnortML, EVE, and the AI-powered Security Assistant.
The Forrester report highlights Cisco’s vision, which seamlessly integrates AI and security into network architectures. Cisco’s ability to combine multi-layer traffic inspection and decryption methodologies sets it apart, while customers praise its strong support, particularly during device migrations.
Moreover, SE Labs has named Cisco Secure Firewall the Best Next-Generation Firewall for the second consecutive year in its 2024 security report, citing Cisco’s product features and customer satisfaction.
Advancements in Threat Defense: FTD 7.6 and AI
Cisco continues to innovate in the field of cybersecurity with the launch of Firewall Threat Defense (FTD) 7.6. This new software enhances security by using AI to prevent zero-day threats and extend application control to over 70 generative AI applications to protect sensitive data. Additionally, FTD 7.6 simplifies branch office deployments through pre-built SD-WAN and firewall templates, supporting zero-touch configuration.
Introducing Cisco Secure Cloud Control
Cisco has further expanded its security ecosystem with Secure Cloud Control, unifying management of Cisco's cloud security offerings. This AI-native solution offers actionable insights and automates issue resolution across hybrid environments. Launched in September 2024, this control center is designed to maximize security investments while streamlining operations.
The Role of AI in Cisco Secure Firewall
In December 2023, Cisco introduced the Security AI Assistant, which integrates machine learning to help organizations make informed decisions, enhance tool capabilities, and automate complex tasks. By leveraging vast telemetry data across network, cloud, applications, and endpoints, Cisco’s AI Assistant improves the accuracy and reliability of threat detection.
For instance, with the new Firewall Policy AI Assistant, administrators can use natural language to identify and optimize policies, eliminating redundant or misconfigured rules. Early testing by a Fortune 500 customer revealed substantial improvements in operational efficiency, with 49% of rules identified as mergeable and 66% of configurations optimized.
Encrypted Traffic Visibility and SnortML
As more data center traffic becomes encrypted, inspecting encrypted traffic has become a critical security challenge. Cisco’s Encrypted Visibility Engine (EVE) enables detection of malware in encrypted traffic without the need to decrypt it, providing visibility into encrypted streams through the use of billions of samples, including sandboxed malware.
Cisco’s SnortML, released in 2024, extends the capabilities of the popular Snort open-source intrusion detection system. SnortML uses machine learning to identify zero-day threats based on models trained on known attack types, such as command injection, code injection, and SQL injection. This proactive defense mechanism ensures Cisco customers stay ahead of emerging threats.
Cisco Talos: A Leading Threat Intelligence Provider
Cisco Talos, one of the world’s largest and most trusted threat intelligence teams, plays a pivotal role in Cisco’s security architecture. With over a decade of expertise, Talos analyzes over 550 billion security events daily, providing critical data to Cisco’s security solutions.
