Zscaler vs. Cisco Umbrella Secure Internet Gateway (SIG)
Cisco Umbrella Secure Internet Gateway (SIG)
Zscaler
Form Factor
Hardware solution shifted to cloud
Legacy architecture limits scaling. Also, Cisco is not optimized for user experience as they do not run all their services in all their PoPs.
Cloud native
Cloud native proxy architecture with unmatched, proven scale and adaptive protection.
SWG/SSE Vision
Lacking
Introduced SWG only in 2018, having previously overlooked its importance. While Cisco has sought to strengthen its SSE offering, it currently lacks a cohesive strategy.
Pioneer
13+ years of SWG and SSE leadership, with analysts acknowledging Zscaler’s vision and ability to execute as reasons for continued leadership.
Architecture
Network- and firewall-centric
Cisco’s legacy network- and firewall-centric architecture cannot deliver the security or agility that our mobile and cloud era demands. Also, Cisco Umbrella SIG is a mix of technologies, making it difficult to use.
Zero trust architecture
Built on the principle of least privilege, the Zscaler Zero Trust Exchange reduces risk across all four stages of the attack chain for all workloads, on-premises or in the cloud.
Integrated Platform
Legacy of fragmented solutions
Cisco’s Umbrella SSE offer relies on multiple discrete products that are only partially integrated.
Well-integrated platform
The Zscaler Zero Trust Exchange™ meets all the SSE needs as a unified, consolidated platform, reducing complexity and cost while securing all users, apps, and data.
Operational Overhead and Costs
Can’t keep up
Legacy architecture requires significant operational overhead and patch management. For example, recently, Cisco warned that a nation-state threat actor exploited two zero-day vulnerabilities (CVE-2024-20353, CVE-2024-20359) in its adaptive security appliances (ASAs), targeting government networks globally.
Always up to date
Our cloud native, proxy-based solution with a single, unified agent minimizes complexities of managing and upgrading SSE components.
Threat Prevention
Lacks advanced security
Cisco Umbrella uses their legacy AMP engine, which lacks advanced security like real-time sandboxing to capture zero-day threats before reaching patient zero.
Advanced, AI-driven protection
Fortifies your defenses, both on-premises and in the cloud, and minimizes risk through a comprehensive suite of AI-driven security services designed to stop ransomware, prevent zero-day threats, and detect unknown malware.
