Branch Office Security -- Zscaler Alternatives
Securing branch offices has traditionally required deploying firewalls, routers, and security appliances at every location — an expensive and operationally complex model. Cloud-delivered SASE replaces this with direct-to-cloud connectivity where branch traffic is inspected in the nearest cloud PoP. Zscaler offers branch connectors and GRE/IPsec tunnels for branch traffic forwarding, but it lacks native SD-WAN capabilities. These alternatives provide integrated SD-WAN and security for branch offices, with Cato Networks and Fortinet FortiSASE leading for organizations that need converged networking and security at the branch.
Inventory all branch office networking and security equipment including routers, switches, firewalls, WAN links (MPLS, broadband, LTE), and local servers. Document bandwidth requirements, application dependencies, and current security controls at each branch. Identify branches running end-of-life equipment or facing capacity constraints as priority migration targets.
Select the branch connectivity model: SD-WAN appliance with cloud security (Cato Socket, FortiGate, Meraki), GRE/IPsec tunnel from existing routers to cloud SASE, or thin-edge appliance with full cloud inspection. Define traffic routing policies — direct-to-cloud for SaaS and internet, SD-WAN overlay for inter-branch and data center connectivity, and local breakout policies for latency-sensitive apps.
Ship and install branch edge appliances (Cato Socket, FortiGate, Prisma SD-WAN ION, Meraki MX, or Cloudflare Magic WAN connector). Configure WAN links, LAN segments, and initial traffic routing. Most modern SD-WAN appliances support zero-touch provisioning — ship to the branch, connect to power and WAN, and configure remotely from the central management console.
Translate on-premises branch firewall rules, URL filtering policies, and IPS signatures into cloud-delivered security policies. Route branch internet traffic through the cloud SASE for SWG inspection, threat prevention, and CASB controls. Maintain any necessary local security functions (east-west segmentation, IoT device policies) on the branch edge device while offloading internet security to the cloud.
Once branch traffic is flowing through the SASE platform and security policies are validated, decommission legacy branch firewalls, proxy appliances, and dedicated WAN optimization devices. Consider MPLS migration to broadband + SD-WAN overlay for significant recurring cost savings. Monitor branch performance through digital experience tools (ZDX, ADEM, ThousandEyes) to validate the new architecture meets SLA requirements.
Custom pricing based on sites, users, and bandwidth
Cato provides the most architecturally pure branch office solution with SD-WAN and security fully converged on a private global backbone. Branch offices connect via Cato Socket appliances and immediately benefit from optimized routing, security inspection, and SLA-backed connectivity — all managed from a single console. No separate SD-WAN or firewall vendors required.
Custom pricing / Per-user tiers starting lower than Zscaler
FortiSASE delivers the most mature SD-WAN integration (Fortinet is the SD-WAN market leader) with FortiOS security inspection at the most competitive pricing. Existing FortiGate branch deployments can extend to FortiSASE seamlessly, and new branches can deploy thin-edge FortiGate appliances with cloud security offload.
Custom enterprise pricing / Per-user or per-Mbps models
Prisma Access with Prisma SD-WAN (formerly CloudGenix) provides enterprise-grade branch connectivity with NGFW-level security inspection in the cloud. Best for organizations with existing Palo Alto branch firewalls that want to migrate to cloud-delivered security while maintaining consistent policy management.
Custom enterprise pricing / Per-user bundled subscription
Cisco Secure Access with Meraki SD-WAN provides the most widely deployed branch networking infrastructure with cloud-delivered security. For the millions of organizations already running Meraki switches, access points, and SD-WAN at branches, adding Cisco's security services is the most natural extension.

Cloudflare Magic WAN and Magic Firewall provide branch connectivity and security through the world's largest Anycast network. While newer than competitors' SD-WAN offerings, Cloudflare's network proximity ensures low-latency connectivity for branches in virtually any location, with competitive pricing and simple deployment.

Zscaler was built as a security-focused cloud proxy and deliberately chose to partner with SD-WAN vendors rather than build its own networking stack. This means Zscaler customers need a separate SD-WAN vendor (like Cisco Viptela, VMware VeloCloud, or Silver Peak) for branch connectivity, adding cost and management complexity. Alternatives like Cato Networks, Fortinet FortiSASE, Palo Alto Prisma Access, and Cisco Secure Access all offer integrated SD-WAN, providing a single vendor for both branch networking and security.
A private backbone (like Cato's) provides predictable, SLA-backed performance for inter-branch and branch-to-data-center traffic, which is important for latency-sensitive applications like VoIP, video, and real-time databases. Internet-based SASE platforms (Zscaler, Netskope, Cloudflare) route traffic over the public internet, which generally works well for cloud/SaaS traffic but may introduce variability for private application access. If your branches primarily access SaaS and internet resources, internet-based SASE is sufficient. If inter-branch communication and data center access are critical, a private backbone or SD-WAN overlay provides better control.
Yes. Many organizations replace expensive MPLS circuits with broadband (cable, fiber, LTE/5G) plus SD-WAN overlay when migrating to cloud SASE. The SD-WAN provides application-aware routing, link bonding, and failover across multiple broadband connections, while cloud SASE provides the security inspection that was previously handled by data center firewalls through backhauled MPLS traffic. Organizations typically save 50-70% on WAN costs by replacing MPLS with broadband + SD-WAN + cloud SASE.
Configure your SD-WAN or branch edge device to route SaaS traffic (Microsoft 365, Google Workspace, Salesforce, etc.) directly to the nearest cloud SASE PoP for inspection and then directly to the SaaS provider, rather than backhauling through a data center. This is called local internet breakout. The cloud SASE platform provides security inspection at the PoP closest to the branch, and the SaaS traffic takes the shortest path to the application. All SASE platforms support this model, and it typically reduces SaaS application latency by 30-60% compared to backhauled architectures.
