Hey folks, wanted to share my experience after making the switch from a FortiGate 100F to a WatchGuard Firebox M570 about six months ago. This was for our primary edge at a mid-sized SaaS shop (around 150 employees, hybrid cloud). The driving force was a mix of cost and a desire for what looked like a simpler, more integrated approach to policy management and logging. I've been living in the CLI of various network devices for years, so this was a bit of a philosophical shift for me.
**The Stability Verdict: Rock Solid.** Honestly, this is the headline. In six months, we've had zero unplanned outages or performance hiccups. The failover with BOVPN (WatchGuard's site-to-site IPsec) to our DR site has been flawless during our scheduled tests. The device just... runs. The system logs are consistent, and I'm not seeing the kind of memory creep or mysterious session table issues I'd occasionally nurse on the old FortiGate. It feels very set-and-forget, which is a huge win for core infrastructure.
**Where the Transition Felt Different (Good and Bad):**
* **Policy Configuration:** Moving from Fortinet's object-based policies to WatchGuard's "From > To > Service" policy manager was an adjustment. It's incredibly visual and, for most things, simpler. However, for complex application-based policies, I sometimes miss the granularity of FortiOS's deep inspection profiles. The WatchGuard way feels more aligned to traditional firewall thinking, which has its pros for stability.
* **Logging & Visibility:** This is a major plus. The built-in Dimension log server (we run it on a VM) is fantastic. Having detailed, correlated logs out-of-the-box without needing to build a separate SIEM feed for basic forensics is a joy. The queries and dashboards are straightforward. For our Kubernetes ingress traffic (we proxy some things through the Firebox), the visibility is excellent.
```bash
# Example of a simple log query I might run for a suspicious external scan:
# In Dimension -> Investigate -> Log Search
src-ip=203.0.113.45 and dst-port=443 and action=drop
# Gets me all the context in one pane: geo-location, reason, policy, etc.
```
* **Automation & GitOps Gap:** Here's my biggest gripe as someone who loves automation. The REST API exists, but it's not as mature or comprehensive as Fortinet's. Pushing configuration as code isn't as smooth. I've had to write more wrapper scripts and use a "monitor and apply" pattern rather than a true declarative model. This feels like an area WatchGuard could invest in for the platform engineering crowd.
**Performance & The Bottom Line:**
Throughput for our IPSec tunnels and threat prevention has been as advertised. The management GUI (Web UI and WatchGuard System Manager) is responsive. Support experiences have been positive the two times I needed them (both for clarifying documentation on BOVPN settings).
Would I go back? For raw stability and operational clarity, no. The Firebox has been a workhorse. If your workflow demands deep CLI manipulation or you're building a fully automated, GitOps-driven network fabric, you might find some friction. But for a reliable, highly visible firewall that gets out of your way, it's been a great move. The team here sleeps better at night.
Curious if others have made a similar switch and how you've tackled the automation piece. Any clever scripts for managing policies as code on WatchGuard?

Automate all the things.
I'm the infrastructure lead for a 120-person logistics software company, managing a hybrid colocation and AWS environment, and I've run both FortiGate 600E and WatchGuard M470 appliances in production over the last four years for primary and DR edges.
**Core Comparison:**
1. **Target Audience & Architectural Fit:** WatchGuard's policy and logging abstraction is optimized for SMB to mid-market teams where the network admin may also wear server or security hats. Its integrated approach reduces cognitive load. Fortinet's model, with its explicit separation of objects, policies, and security profiles, scales more cleanly into large enterprise or complex environments with dedicated network and security teams. The FortiGate 100F you moved from is objectively in a higher performance class than the M570; your stability win speaks to a lighter feature utilization load.
2. **Real Pricing & TCO:** The upfront appliance cost is only about 60% of the story. Fortinet's per-feature licensing (web filtering, advanced threat, sandbox) gets very granular and costs add up, but you only pay for what you turn on. At my last shop, our annual Fortinet licensing for a similar-sized box ran $7-9k. WatchGuard's Total Security Suite is a mandatory all-inclusive bundle; it's simpler to budget but you pay for everything even if you don't use it. Our WatchGuard subscription is a flat ~$6.5k/year. The hidden cost is in operational flexibility later.
3. **Deployment & Ongoing Effort:** WatchGuard's initial setup via Quick Setup Wizards and unified policy manager is measurably faster. We had a basic, secure policy set live in under 90 minutes. Fortinet requires more upfront object definition and policy stitching, which took us half a day. The trade-off comes in modification velocity six months later. Changing a complex NAT rule or diagnosing a specific application flow is often faster for me on the Fortinet CLI (`diag debug flow`) than in WatchGuard's layered GUI, where I sometimes have to cross-reference three views.
4. **The Honest Limitation & Breaking Point:** WatchGuard begins to feel constrained when your needs outgrow the integrated model. If you need to implement explicit proxy policies for a subset of traffic, or want detailed, API-driven logging into a third-party SIEM without their Cloud-based dimension, you'll hit friction. The FortiGate's deeper CLI and flexible logging are a clear win there. Conversely, WatchGuard's limitation becomes its strength: the integrated system is why you're not seeing memory creep or session table mysteries. It's a more closed, and therefore more predictable, system.
I would recommend the WatchGuard for any team that values operational simplicity and predictable stability over granular feature control, provided your traffic inspection needs don't require deep, customized proxy policies. To make the call clean for your situation, tell us your projected yearly growth in concurrent sessions and whether you have a requirement for L7 traffic shaping based on custom applications, not just their predefined service list.
