As Microsoft steps into the SSE market, the question arises: "How Zscaler's and Microsoft's solution differ from each other?" In this blog, we are going to compare Zscaler SSE against Microsoft's Global Secure Access to highlights their key features, strengths, and limitations.
Understanding Secure Service Edge (SSE) Solutions
Secure Service Edge (SSE) solutions are designed to provide comprehensive security for cloud-based and hybrid environments. SSE integrates various security functions, including Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and Cloud Access Security Broker (CASB), into a unified service. This approach helps organizations enforce security policies consistently, regardless of where applications and users are located.
By adopting SSE, organizations can protect their data, manage access to applications, and ensure compliance with regulatory requirements. The need for such solutions has grown significantly as businesses increasingly rely on cloud services and remote workforces.
According to Gartne : "By 2026, 85% of organizations seeking to secure their web, SaaS and private applications will obtain the security capabilities from a security service edge (SSE) offering"
Key Features and Capabilities: Zscaler SSE vs. Microsoft Global Secure Access
Both Zscaler SSE and Microsoft Global Secure Access offer robust SSE solutions, but there are key differences in their features and capabilities. Zscaler is known for its comprehensive security platform that includes SWG, ZTNA, CASB, FWaaS and more. Zscaler’s cloud-native architecture ensures scalability and high performance, making it a preferred choice for many enterprises.
Microsoft Global Secure Access, part of the Microsoft Entra suite, focuses on identity-centric Zero Trust Network Access (ZTNA). It integrates seamlessly with Microsoft’s ecosystem, offering Conditional Access (CA), multifactor authentication (MFA), and single sign-on (SSO). While it provides strong identity and access management capabilities, it may not cover the full spectrum of SSE components as extensively as Zscaler.
Comparison Table: SWG and ZTNA Components
Below is a high-level comparison table showcasing the availability of important SSE components for both solutions:
| Component | Zscaler SSE | Microsoft Global Secure Access |
| Secure Web Gateway (SWG) | Yes | Limited |
| Zero Trust Network Access | Comprehensive | Identity-Centric |
| Cloud Access Security Broker(CASB) | Yes | Not Available |
| Single Sign-On (SSO) | Yes | Yes |
| Multifactor Authentication | Yes | Yes |
| Conditional Access | Yes | Yes |
| Advanced Threat Protection | Yes | Limited |
| OS Support for the Client | Windows, Linux, Mac, IOS, Android | Windows, Mac (Preview), IOS, Android (Preview) |
| Private Access Connector | Redhat 9 - License Included | Windows Server |
| Identity Provider Support | Multiple (e.g. Entra ID, Okta, Ping Identity) | Entra ID Only |
| SSL Inspection | Yes | Not Available |
| Sandbox | Yes | Not Available |
| File Type Control | Yes | Not Available |
| Web Content Filtering | Comprehensive (Cloud Apps, Web Category) | Limited (Web Category Only) |
| Custom URL Limit | 25 K | 8 K |
| Cloud Firewall | Yes | Not Available |
| Tenant Restriction | Comprehensive (Microsoft Apps, Google Apps, AWS, GitHub, Slack Dropbox, etc.) | Microsoft Apps Only |
| Branch Connectivity | IPSec, GRE, Private Service Edge | IPSec |
| Disaster Recovery | Yes | Not Available |
| Geolocation | Customer Managed SIPA, Zscaler Managed SIPA(Dedicated IP) | Customer Managed SIPA |
Deployment, Compatibility, and Stability Analysis
Deployment of Zscaler SSE is straightforward due to its cloud-native architecture, which eliminates the need for on-premises hardware. This ensures rapid scalability and seamless integration with existing IT infrastructures. Zscaler also offers extensive cross-platform compatibility, supporting a wide range of devices and operating systems.
Microsoft Global Secure Access, while robust within the Microsoft ecosystem, may face challenges when integrating with non-Microsoft environments. Its deployment process can be more complex, especially for organizations not fully embedded in Microsoft services. However, for businesses already using Microsoft 365 and Azure, provides a solution that may cover their needs.
In terms of stability, both solutions are reliable, but Zscaler's long-standing presence in the SSE market and its dedicated focus on security services give it an edge. Microsoft’s solution is evolving, but its broader focus on multiple IT services can sometimes impact the specialization and stability of its security offerings.
Conclusion
Choosing between Zscaler SSE and Microsoft Global Secure Access depends largely on an organization's existing infrastructure and specific security needs. Zscaler offers a more comprehensive and specialized SSE solution, making it ideal for enterprises seeking extensive security coverage across various components.
Microsoft Global Secure Access is a strong contender for businesses deeply integrated with the Microsoft ecosystem, offering excellent identity and access management capabilities. However, it may fall short in providing a holistic SSE solution compared to Zscaler.
Ultimately, both solutions have their merits, and the right choice will depend on the specific requirements and existing frameworks of your organization. Consider conducting a thorough assessment of your security needs and infrastructure compatibility before making a decision.
