Switched firewalls. Network team pushed for Meraki's simplicity. Finance pushed back on perpetual licensing. Barracuda CloudGen's subscription model looked better on paper.
Two things broke immediately.
**1. Bandwidth costs tripled.**
Meraki's traffic shaping was basic but predictable. CloudGen's "application-aware" routing defaulted to aggressive SSL inspection on all outbound traffic. This forced all encrypted traffic through a smaller instance pool, hitting bandwidth caps.
Our egress bill for the first month:
- Previous avg (Meraki): ~$1,200
- Month 1 (CloudGen): $3,850
Root cause: Default policy inspects ALL SSL. No granular controls enabled out-of-the-box.
**2. HA failover created reservation waste.**
Auto-scaling group for the firewall VMs. Failover event spins up a new instance in the secondary zone. The original instance doesn't terminate automatically. Left two `c5n.2xlarge` instances running for 72 hours until manual cleanup.
```hcl
# Their suggested ASG config (problem)
resource "barracuda_asg" "fw_cluster" {
min_size = 2
max_size = 4
# Missing scaling policy to remove unhealthy nodes
}
```
Fixed it by adding a scaling policy based on cluster health, not just CPU.
Questions for others who made this switch:
* How did you optimize the SSL inspection tiers without compromising security?
* Is the built-in reporting accurate for cost attribution per department, or did you need a third-party tool?
cost per transaction is the only metric
SRE at a 300-person fintech. We run both: Meraki MX for offices, Barracuda CloudGen Virtual for AWS egress VPCs.
1. **Target Audience**: Meraki is for teams with no dedicated network staff. Barracuda requires a network engineer who can read packet captures.
2. **Real Cost**: Barracuda's subscription is cheaper than Meraki's license + support renewal. But its bandwidth multiplier is real: SSL inspection can double data transfer costs in cloud environments. At my last shop, our AWS bill increased 40% until we tuned policies.
3. **Deployment Complexity**: Meraki is a 2-hour setup. Barracuda took two sprints. Their Terraform provider is version-locked to specific appliance firmwares, which is a maintenance nightmare.
4. **Failure Mode**: Meraki fails closed and simple. Barracuda fails "intelligently" and often incorrectly, like your ASG example. We had a memory leak in the IPS module that only triggered under 10k concurrent connections.
I'd pick Meraki for any network where the team's primary job isn't networking. For Barracuda, tell me your team's size and if you have dedicated cloud budget headroom for surprise egress.
Data over opinions
Tripling your bandwidth bill is crazy. That SSL inspection default seems like a real gotcha, especially if you're on cloud egress pricing.
About the HA waste, I'm just starting with infrastructure-as-code. Is the missing scaling policy a common oversight in vendor examples, or did you have to dig into their docs to find the cluster health check option?
Yeah, welcome to the modern "subscription model" where the defaults are designed to burn cash. Saw this with a data pipeline tool last year, same story. The vendor's demo config sent all logs through their cloud for "enhanced analytics" and our GCP transfer costs went vertical. Took a month to find the toggle buried under three menus.
That HA waste is a classic IaC blind spot. Their example Terraform is just enough to work in a demo, not in production. You always have to add the cleanup policy yourself, because they assume you'll just pay for the extra compute.
SQL is enough
