SASE & Zero Trust: 9 Tools compared

Cato Networks is the pioneer of the single-vendor SASE platform, converging SD-WAN, SWG, CASB, DLP, ZTNA, FWaaS, and advanced threat prevention into a single cloud-native service built on a private global backbone. Unlike competitors that bolt together acquired products, Cato built every SASE component from the ground up on a single software stack and operates its own global backbone of 80+ PoPs connected by SLA-backed private links, providing predictable performance that internet-based SASE solutions cannot guarantee. Cato's architectural purity and simplified management make it particularly attractive for mid-market organizations.

Cloudflare Zero Trust (formerly Cloudflare for Teams) leverages Cloudflare's massive global network of 300+ cities to deliver zero trust security services including a secure web gateway, DNS filtering, browser isolation, CASB, DLP, and zero trust network access. Built on the same Anycast network that handles a significant percentage of global internet traffic, Cloudflare offers strong PoP proximity to users, a developer-friendly approach to configuration via Terraform and APIs, and an aggressive pricing model that includes a generous free tier for small teams.

iboss is a cloud-native zero trust security platform that delivers SWG, CASB, DLP, ZTNA, and browser isolation through a containerized architecture running on all major cloud providers (AWS, Azure, GCP). Founded in 2003 as a web security company, iboss re-architected its platform from the ground up for cloud delivery, offering a zero trust SASE solution that is particularly well-suited for mid-market organizations and government agencies. Its FedRAMP High authorized status and competitive pricing make it a strong choice for public sector and cost-conscious enterprises.

Palo Alto Prisma Access delivers SASE through Palo Alto Networks' cloud infrastructure, bringing the same next-generation firewall security policies that enterprises have relied on for over a decade into a cloud-delivered service. Prisma Access combines ZTNA 2.0, Cloud SWG, FWaaS, CASB, DLP, SD-WAN (via Prisma SD-WAN), and Autonomous Digital Experience Management (ADEM) into a unified platform. Its key differentiator is enabling organizations already invested in Palo Alto's on-premises NGFW to extend those same policies and management workflows seamlessly to remote users, branch offices, and cloud workloads.

Zscaler is one of the largest inline cloud security platform, delivering Secure Access Service Edge (SASE) and zero trust connectivity to enterprises globally. Built on a purpose-built cloud architecture with over 150 data centers worldwide, Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA) inspect all traffic. Including encrypted TLS/SSL. To enforce security policies, prevent data loss, and block threats without the latency and complexity of legacy appliance-based architectures. Zscaler eliminates the need for VPNs, firewalls at branch offices, and traditional network security stacks by routing all user traffic through its global cloud for inspection and policy enforcement.
