Enterprise SASE Platforms FAQ
Should I choose a SASE platform from my existing firewall vendor?
Choosing your existing firewall vendor's SASE offering has clear advantages: unified policy management, familiar interfaces, and leveraging existing investments. Palo Alto, Fortinet, and Cisco all offer compelling SASE that integrates with their on-prem gear. However, these platforms evolved from appliance architectures and may lack the cloud-native scalability and inspection depth of purpose-built platforms like Zscaler. If you plan to fully eliminate on-prem appliances, a cloud-native SASE may be the better long-term choice. If you need hybrid on-prem and cloud security with unified management, your existing vendor's SASE is a pragmatic path.
How does pricing for enterprise SASE compare to Zscaler?
Fortinet FortiSASE is typically the most competitively priced, often 30-50% less than Zscaler for comparable capabilities, especially when factoring in SD-WAN. Cisco Secure Access pricing varies significantly based on existing agreements and bundle discounts. Palo Alto Prisma Access is often the most expensive option when including all required modules. Zscaler sits in the premium tier alongside Palo Alto. For budget-constrained enterprises, Fortinet offers the most SASE capability per dollar.
Which enterprise SASE platform has the best SD-WAN integration?
Fortinet FortiSASE has the most mature and deeply integrated SD-WAN, leveraging years of FortiGate SD-WAN leadership. Palo Alto Prisma SD-WAN (acquired from CloudGenix) is well-integrated but still maturing. Cisco Secure Access integrates with Meraki SD-WAN for branch connectivity. Cato Networks (in the cloud-native category) also has excellent native SD-WAN. Zscaler notably lacks native SD-WAN and relies on partner integrations, which is a significant gap for branch-heavy enterprises.
Can enterprise SASE platforms match Zscaler's inline inspection depth?
Palo Alto Prisma Access comes closest, with full NGFW-grade inspection in the cloud including advanced threat prevention, WildFire sandboxing, and continuous trust verification with ZTNA 2.0. Fortinet FortiSASE provides solid FortiOS-based inspection but may lack the throughput of cloud-native architectures. Cisco's Umbrella SWG historically focused on DNS-layer security and is still building out full inline inspection. For the deepest inline inspection, Zscaler and Palo Alto Prisma Access lead, though their architectures differ fundamentally.
