I recently oversaw a security stack migration for a non-profit organization (~50 users, primarily remote, mixed SaaS/on-prem legacy apps). Their previous solution was Cisco Umbrella (DNS-layer security module). We moved to DNSFilter after a 90-day proof-of-concept. The decision was driven by budget constraints and a need for more granular, real-time reporting.
From a performance and operational standpoint, here are my observed metrics:
**Latency & Resolution Impact (Averages over PoC)**
* **DNS Resolution Latency (to resolver):** Umbrella added ~12-15ms (when using their global anycast nodes). DNSFilter added ~8-11ms. Both are negligible for user perception, but DNSFilter was consistently faster in our geographic region.
* **Policy Update Propagation:** DNSFilter changes applied near-instantly (<60s). Umbrella policy updates sometimes took 3-5 minutes to propagate fully, which caused minor workflow disruptions during testing.
* **Reporting Latency:** This was a key differentiator. DNSFilter's threat event logging appeared in the dashboard within 2-3 seconds. Umbrella's reporting dashboard often had a 90-120 second lag for the same category of event.
**Configuration & Management Overhead**
Umbrella's integration with the existing Cisco stack (Meraki) was seamless, but the dashboard felt heavy. For a small team with no dedicated security personnel, DNSFilter's UI was significantly faster to navigate. Policy creation was also more straightforward:
```yaml
# Example of DNSFilter's category-based rule (simplified)
- policy: "Block High-Risk & Distraction"
categories:
- malware
- phishing
- cryptomining
- streaming_audio_video
action: block
apply_to: "All_Remote_Users"
```
Umbrella required more steps to achieve the same, involving both policy objects and block lists.
The primary advantage of Umbrella was its broader threat intelligence context (from Talos) and its ability to proxy HTTP/HTTPS traffic for deeper inspection—a feature we didn't utilize due to performance overhead concerns. DNSFilter's strength was its speed, cost-effectiveness, and the clarity of its real-time blocking page for end-users.
For a charity of this size with limited IT resources, **DNSFilter proved operationally superior** in terms of agent deployment speed, dashboard responsiveness, and monthly cost. However, I am curious about long-term efficacy against zero-day threats. Has anyone else conducted a similar migration and measured the threat catch rate or false positive ratio over a longer period? I only have our 90-day PoC data.
sub-10ms or bust
1. I'm an infra lead for a 250-person fintech, mostly remote. We run DNSFilter in prod for our endpoint and network-based DNS security.
2.
- **Target Fit**: Umbrella is built for Cisco shops with big enterprise budgets. DNSFilter targets SMB and mid-market, which is exactly what a 50-user charity is.
- **Real Pricing**: DNSFilter's advertised $4.50/user/mo for the mid-tier is usually final. Umbrella's list price starts higher, but you can haggle. Expect 1.5-2x the cost for the full suite, plus potential add-ons.
- **Deployment Effort**: DNSFilter is a DNS change. Umbrella can be that too, but for full value you deploy roaming clients and maybe virtual appliances. That's more work for your legacy on-prem apps.
- **Breaking Point**: DNSFilter's web filtering is solid, but it's a DNS tool. Umbrella's SIG module does SSL inspection, which DNSFilter can't touch. If your charity needs to decrypt and inspect HTTPS traffic later, Umbrella wins and you'll have to migrate again.
3. My pick is DNSFilter for your charity. It's the right fit on cost and complexity. Confirm you'll never need SSL inspection and that your legacy apps work with a simple DNS resolver change.
Simplicity is the ultimate sophistication
Your point on SSL inspection is the critical one. For a charity at that scale, needing SIG would mean they're already facing compliance or insurance requirements demanding deep traffic inspection - a scenario where Umbrella's premium starts to make sense.
But if they don't need it now, they likely never will. The operational lift and cost for SIG are disproportionate for a 50-user team unless they're handling highly sensitive donor data. You're right to call for that confirmation; it's the single decision point that locks them in.
Less spend, more headroom.
