How are they built and run?
Cato Networks
Architecture
Cato states the platform is a "purpose-built and self-optimizing global cloud with a single-pass engine, single data lake, and single policy enforcement". Its inspection engine is named the Cato Single Pass Cloud Engine (SPACE).Source: Cato Networks homepage
Network
Cato states its private backbone, branded Cato Neural Edge, is a "cloud-native, private global backbone spanning 100+ PoPs worldwide" with "embedded GPU-powered compute". Sites, users and clouds connect over encrypted tunnels to nearby Cato PoPs, and traffic is carried on the backbone with path selection.Source: Cato global private backbone
Management and policy
Cato states "one policy engine, one console, single-pass inspection, on an SLA-backed global backbone". Managed service partners get "one multi-tenant console".Source: Cato SASE platform
Zscaler
Architecture
Zscaler describes a "proxy architecture" that "enables full TLS/SSL inspection at scale", brokering one-to-one connections. Single-pass wording is not used on the pages we read.Source: Zscaler Zero Trust Exchange
Network
Zscaler positions direct-to-app connectivity without backhauling traffic through data centers or stacks of appliances. A private backbone and a data center or PoP count are not stated on the pages we read.Source: Zscaler SASE
Management and policy
Zscaler states a "unified, cloud native platform". A single console for networking and security is not described on the pages we read.Source: Zscaler SASE
How do they handle vulnerabilities and compliance?
Cato Networks
Vulnerability response
Cato states it performs virtual patching through the IPS layer of SPACE, with new IPS rules deployed "without requiring any customer involvement", in four steps: assessment, development, opt-in protection in simulate mode, then global protection. It publishes a Detect to Protect log of critical CVEs; most 2026 entries read 1 or 2 days.Source: Cato Rapid CVE Mitigation
Certifications listed
Cato's compliance page lists SOC 2 and SOC 3, PCI-DSS Level 1 Service Provider, ISO/IEC 27001, 27017, 27018, 27701 and 14001, UK Cyber Essentials, CSA STAR Self-Assessment, GDPR and Spain ENS High. FedRAMP is not listed on that page.FedRAMP listed: Not listed
