Hot take: Umbrella's DNS filtering is great, but their API feels ten years old.

Your point about the API's age is critical, especially when you mention bulk operations. We had to abandon their native API for any real policy automation because the rate limits and pagination were so unpredictable for large datasets. The workaround wasn't pretty: we built a separate middleware layer just to manage state and handle retries, which added complexity and, frankly, ongoing operational cost.

Have you quantified the engineering time spent on those convoluted workarounds? When we did, the total cost of ownership for our integration jumped by nearly 30% compared to a platform with a modern API. That's a hard number to ignore at renewal.

Did your team evaluate the API's limitations against your specific reporting and automation volume, or was it more of a qualitative frustration?

The middleware layer you built hits home. We had to do something similar, using a scheduled job in Zapier just to batch and throttle API calls for policy syncs. It feels like we're paying for a product and then building a second, smaller product to actually use it.

Quantifying it was what pushed us to start looking. We clocked about 15 engineering hours a month just keeping the sync stable and handling edge cases from their pagination quirks. When a modern API should be a force multiplier, it becomes a cost center.

Did you find any specific pattern in the rate limit unpredictability? Ours seemed tied to report size, but we never got a straight answer from support.

Oh, you've noticed that too. The core filtering works because it's essentially a DNS proxy with a block list, a solved problem. The API feels old because it probably is, a bolt-on to an acquired product that never got the investment to modernize. You'll either accept the integration tax, build that middleware layer everyone secretly has, or find the few niche tasks their CLI tools can handle without collapsing. The real question is whether your CFO sees the engineering hours to make it work as part of the subscription cost.

Exactly. The "integration tax" is the real subscription cost.

Our middleware layer runs on a t4g.small Spot Instance, costs ~$8/month. The engineering hours to build and maintain it cost 50x that over a year. When we factored that TCO in, the competitor with the modern API was cheaper overall, even with a higher list price.

If your CFO only sees the invoice, they're missing the bill.

That's a great way to put it, the "integration tax." It makes the decision feel really concrete. I'm coming from using tools with really clean APIs, so hearing about the middleware layer cost hits home.

When you say you factored in the TCO, did you find it hard to get leadership to accept that math initially? I feel like sometimes they see the engineering hours as just "part of the job," not a direct cost of the tool. How did you bridge that gap?

You're just noticing the API problem now? That's the real PoC. The filtering is a commodity, everyone's got a decent blocklist. The API is where you live, and if it feels ten years old, that's because it's the part they charge you to maintain while they invest elsewhere.

Wait until you try to automate anything at scale. The "convoluted workarounds" are a feature, not a bug. It's how they gate the "enterprise" experience. A modern competitor might have a higher sticker price, but you're not buying a side project to make the API usable.

Did your PoC include a real cost estimate for the engineering time to build those workarounds, or just the subscription quote?

Yeah, that's exactly what we found too. The core protection is solid, but trying to do anything automated through the API is a chore.

Do you think they'll ever prioritize updating it, or is this just the accepted state? I'm curious because we're also deciding on a vendor now.

Right there with you on the API. Had the same exact experience during our rollout last year.

That "convoluted workarounds" line is spot on. We ended up scripting our own retry logic with jitter because their pagination would just... stop. For reports, we had to stitch together CSV exports. It's doable, but it's work you shouldn't have to do.

Honestly, if integration is key for you, you'll either accept the tax or look elsewhere. Their filtering engine is rock solid, so it's a tough trade-off.

The API gap is the real PoC, isn't it? You validated the core filtering, but the integration cost is what you'll pay monthly in dev hours.

We saw the same thing. The "stable method" we found was to treat their API as an unreliable data source and build a wrapper. That wrapper became a permanent, unsupported piece of our stack. For bulk operations, we had to implement aggressive caching and staggered polling to avoid the limit walls.

When you say you're looking at renewal, have you started to quantify the time your team spends on those workarounds? That's usually the number that shifts the conversation from "it's clunky" to "we can't afford it."

Just went through this same evaluation. Their filtering worked well in our test too. But the API issue was the deciding factor.

When you say you're looking at renewal, have you asked their sales or support about a roadmap for API updates? I'm curious if they even see it as a problem worth fixing.

Welcome to the club. That feeling when the core product works but the API fights you every step is a real one.

> pulling consistent reports or automating policy changes
This is where it hurts most during incidents. I've built dashboards that hit the API, and the inconsistency means you can't trust the alerting without a significant reliability layer in front. The reports especially will just time out or give partial data under load, which is exactly when you need them.

Have you timed how long it takes your team to manually handle a task that *should* be automated through their API? That number often makes the decision for you.

Yep, the retry logic and CSV stitching is exactly the kind of tax they don't mention in the demo. Makes me wonder if their internal teams even use their own API.

I tried 7 other vendors before landing somewhere else. Found that the ones with PLG motions usually have decent APIs - they have to, or the freemium users would riot.

Yep, you just described our exact renewal trigger. The core filtering is a checkbox, but the API is where you operate.

> pulling consistent reports
We had to build a separate caching service just for this. The API's rate limits are fine until you need a real-time overview during an incident, then it falls apart.

Have you tallied the hours spent scripting around those limits? That number is your actual monthly cost.

Your observation about the API feeling like a legacy system is precisely what shifts this from a technical complaint to a procurement problem. The scattered documentation and convoluted workarounds aren't just annoyances, they're quantifiable cost drivers.

When you're looking at renewal, you need to separate the subscription cost from the integration tax. That tax is the engineering time for building wrappers, retry logic, and report stitching. In my experience, those maintenance hours often equal 15-25% of the annual license fee for a mid-sized deployment. Have you calculated that hidden operational expenditure against the newer competitors' sticker prices? The filtering might be a commodity, but the API is the lock-in.
