How to Choose a Cloud Firewall

Answer three questions in order. Where must enforcement live — single-cloud native (AWS/Azure), multi-cloud platform (CloudGuard, Fortinet), or in the network fabric (Aviatrix, Valtix)? How deep must inspection go segmentation and egress (native services, Aviatrix) versus full NGFW prevention (Cloud NGFW, CloudGuard, FortiGate)? Who operates it managed (Cloud NGFW, MCD), self-run VMs, or embedded fabric? Then test the two things datasheets hide: east-west enforcement at your scale, and per-GB processing cost at your real traffic volumes (usage pricing punishes chatty microservices). Cloud firewalls are one layer of a cloud security program; pair them with your NGFW estate and zero-trust architecture.

FAQ

What is a cloud firewall?

A cloud firewall controls traffic to, from, and between cloud workloads delivered as cloud-native services (AWS/Azure Firewall), virtual/managed NGFWs (Cloud NGFW, CloudGuard, FortiGate-VM), or enforcement embedded in cloud network fabrics (Aviatrix, Multicloud Defense). It covers what data-center appliances can’t reach.

Are cloud-provider native firewalls good enough?

Often, for single-cloud estates: AWS Network Firewall and Azure Firewall handle segmentation, egress filtering, and IPS-style rules with native IaC integration.

Multi-cloud organizations, or those needing NGFW-grade application control and sandboxing, typically layer a vendor platform on top.

What’s the difference between a cloud firewall and FWaaS?

Direction of protection. Cloud firewalls protect workloads in clouds (VPC traffic, east-west, egress).

FWaaS protects users and branches via cloud-delivered inspection. Vendors increasingly sell both, but the traffic they see and the buyer who owns them differ.

Do I need east-west (lateral) firewalling in the cloud?

Increasingly yes. Breaches move laterally after initial access, and flat VPCs make that easy.

Security groups provide basic segmentation; distributed enforcement (Aviatrix), managed NGFWs on transit paths, or CloudGuard gateways add inspection where lateral movement happens.

What happened to Valtix?

Valtix became Cisco Multicloud Defense after Cisco’s 2023 acquisition. Its cloud-agnostic control plane continues under Cisco; pricing moved into Cisco’s SaaS subscription motions. Standalone-era independence is gone; multi-cloud capability remains.

How are cloud firewalls priced?

Native services bill by usage (endpoint/deployment hours plus per-GB); managed NGFWs by consumption tiers; virtual appliances by license plus compute; fabric platforms by network consumption. Model your real east-west traffic usage pricing rewards efficient architectures and punishes chatty ones.

Conclusion

Palo Alto’s Cloud NGFW leads on managed depth, Fortinet on licensed value, and Check Point CloudGuard on tested multi-cloud prevention with AWS and Azure Firewall owning their native lanes, Aviatrix and Valtix/MCD redefining where enforcement lives, and Sophos and Zscaler serving SMB and zero-trust-workload needs.

Decide where enforcement must live first; the vendor follows. Price at your real traffic, in your real shape, before committing.
