Firewall-as-a-Service (FWaaS)
Your firewall, delivered from the cloud.
FWaaS delivers firewall and network security as a cloud service.
Inspect every flow. No blind spots.
Inspect internet, WAN, and LAN traffic with no limits on ports, protocols, or encryption.
Retire the appliances. Keep the protection.
Replace branch, data center, and LAN firewalls with one cloud-native service.
Legacy firewalls can't keep up.



Appliance scaling limits
Physical and virtual firewalls run out of compute — TLS inspection, CPU load, and packet drops force mid-term hardware replacement.
Config sprawl, inconsistent enforcement
Branch, data center, and LAN firewalls multiply rulesets and misconfigurations, so enforcement drifts from site to site.
Lateral movement on the LAN
Flat internal networks let threats spread once inside — perimeter firewalls never see east-west or LAN traffic.
One firewall. Everywhere.
Cato delivers firewall as a service from a single cloud-native platform — replacing branch, data center, and LAN firewalls with one always-on engine. Every user, site, and cloud is governed by the same policy and inspected at full throughput, with no limits on ports, protocols, or encryption, so protection scales with your business instead of your hardware.
FWaaS empowers the business white paperConverge in the cloud
Replace branch, data center, and LAN firewalls with a single cloud-native FWaaS — no hardware to size or patch.
Detailed analysis and reporting
Get full visibility into every flow with detailed analytics and reporting across users, sites, and clouds.
Enforce one policy everywhere
Apply consistent access control and zero trust across every user, site, and environment.
Real-World Business Value with FWaaS
Firewall-as-a-Service (FWaaS) Capabilities
Full traffic inspection without blind spots
Inspect all traffic with no limits on ports, protocols, or encryption.
- Inspect internet, WAN, and LAN traffic — no blind spots
- Multi-gig throughput from the cloud
- Replace branch, data center, and LAN firewalls

DPI-based application and user awareness
A DPI engine identifies the application as early as the first packet, without decrypting the payload.
- Built-in awareness of thousands of applications
- Identify apps on the first packet, no decryption
- Tie a user identity to every network flow

AI-powered policy management
Rich object-based rules for WAN, internet, and LAN, enhanced by AI-based autonomous policies.
- Build rules from identity, device, app, location, and more
- Autonomous policies flag misconfigurations and optimize rulesets
- Real-time zero trust enforcement, fewer errors

Microsegmentation, access control & zero trust
Restrict access to sensitive resources and stop lateral movement.
- Segment by groups, networks, VLANs, hosts, users, and devices
- Identity-to-identity, identity-to-app, and app-to-app policies
- Factor geo, connectivity, and security posture into access

Full logging and monitoring
Every rule and action can record an event, stored on the Cato SASE Cloud for your retention period.
- Configurable event logging and email alerts
- Dashboards with easy search and filtering
- Full admin audit trail for compliance

Unlimited processing and inspection capacity
Capacity isn't bound by hardware — autonomous, elastic scaling and self-healing keep performance high.
- Enable every feature, including TLS inspection, freely
- No latency from CPU load, packet drops, or device failure
- No mid-term appliance replacement

Customers love Cato
We had five different firewall vendors across our locations, and none of them were talking to each other. When your tools don't integrate, you can't see the full picture-and the gaps you can't see are exactly where the risk is.
