Zscaler internet access overview

Zscaler internet access (ZIA) claims to provide secure internet and SaaS applications access through its cloud native security service edge (SSE) platform. Security service edge is a network security solution offered through a specialized cloud platform. Further insights can be found in the comprehensive SSE article. Its core services encompass secure web gateway (SWG), zero trust network access (ZTNA), cloud access security broker (CASB), and firewall as a service (FWaaS).

Features & integrations

ZIA incorporates security features, including a cloud firewall, intrusion prevention system (IPS), data loss prevention (DLP), bandwidth control, browser isolation, cloud access security broker (CASB), and sandbox capabilities.

Although Zscaler has products that provide wider integration with various platforms, Zscaler internet access is integrated only with threat intelligence platforms (TIP), making it capable of leveraging up-to-date threat intelligence for proactive defense strategies. However, it lacks integration with IPAM, SOAR, and ITSM solutions.

User reviews

Likes

• Cloud security software offers comprehensive protection with features like web filtering, antivirus, anti-malware, advanced threat protection, and data loss prevention.
• Scalability and central security policy management are key advantages, enabling quick deployment and efficient management across the organization.

Dislikes

• Subscription-based model and internet dependency may pose challenges for some organizations.
• Limited customization compared to on-premises solutions can be a drawback for specific security requirements¹ .

Palo Alto Networks Prisma Cloud

Another Zscaler internet access alternative is Prisma Cloud by Palo Alto Networks, positioned as a cloud native security platform (CNSP), which claims to provide comprehensive security and protection for cloud applications.

Features & integrations

Palo Alto Networks’s Prisma Cloud is integrated with SOAR capabilities. However, it lacks integrated features for IPAM and TIP, as well as ITSM functionalities. This indicates a focus on advanced security automation and response, but organizations may need to integrate additional tools for comprehensive network management and leveraging threat intelligence effectively. It is deployed in the cloud environment.

User reviews

Likes

• Prisma Cloud provides comprehensive reports on vulnerabilities and emerging threats, along with detailed remediation instructions, enhancing security management.
• It offers detailed insights into cloud applications and activities, simplifying the detection and monitoring of unknown threats.

Dislikes

• Scanning expansive cloud environments may be slow, and the platform could offer more flexibility and interoperability for diverse infrastructures.
• There are occasional concerns about the platform’s ability to handle large-scale deployments and high-volume sensitive data processing without compromising performance or reliability² .

Cisco Umbrella

Umbrella is a cloud security service that forms the foundation of SASE architecture. It integrates various security functions such as firewall, secure web gateway, DNS-layer security, cloud access security broker (CASB), and threat intelligence solutions into a unified cloud service.

Features & integrations

Cisco Umbrella integrates with SOAR, TIP, and ITSM platforms making it suitable for organizations looking for comprehensive security management. However, the absence of integration with IPAM may require additional configurations or solutions for IP management.

Cisco Umbrella is deployed entirely in the Cisco cloud, offering scalability, accessibility, and simplified management for organizations looking for a cloud native security solution. However, this cloud-based deployment may pose challenges for organizations with specific on-premises infrastructure needs or regulatory compliance requirements.

This integration enhances overall security by providing timely analysis of security events. For more, see firewall audit software.

Brief summary of key integration points to consider include:

1. IP address management (IPAM) integration

Seamless integration with IPAM solutions ensures accurate IP address tracking and management, minimizing security risks associated with mismanaged IP addresses.

2. Security orchestration, automation, and response (SOAR) integration

Integration with SOAR platforms automates incident response, enhancing security incident management efficiency.

3. Threat intelligence platform (TIP) integration

Integration with TIP provides secure access to up-to-date advanced threat intelligence, enabling proactive defense against unknown threats.

4. IT system management (ITSM) integration

Integration with ITSM systems streamlines firewall management processes within broader IT service management frameworks.

5. Deployment

Vendors should offer flexible deployment options to accommodate diverse organizational needs. Choices such as on-premises, cloud-based, or hybrid deployment models allow organizations to optimize infrastructure, scalability, and accessibility according to their specific requirements.
