For Engineering Leaders

Your Engineer Wants to Buy Instead of Build. They’re Right.

Someone on your team found this page and sent it to you. That means they've already evaluated it and think it's worth your attention. Here's the short version of why they're correct, in terms that make sense in a budget conversation.

The Numbers

What Building It Yourself Actually Costs

Before your team can write the first detection rule, someone has to build the telemetry layer that feeds it. This is what that work realistically looks like:

3–5
Years to production-quality kernel telemetry, built from scratch
3–5
Senior kernel engineers required — a rare and expensive discipline
$3M–$8M
Estimated engineering cost before you ship a single feature customers see
Day 1
Time to receiving kernel events with the Heathen SDK

These numbers are not marketing estimates. They reflect the reality that correct, production-grade Windows kernel driver development — the kind that passes Microsoft’s Driver Verifier, survives Patch Tuesday, and runs on every supported Windows version without BSOD — is a specialization that takes years to build and is genuinely scarce on the market. Your engineers are good. Kernel driver development is a different job.

Common Questions

The Objections, Answered Honestly

We’re a software company. We should own our own stack.
You should own the parts of your stack that differentiate your product. Detection logic, response orchestration, customer dashboards, threat intelligence integrations — those are your moat. Kernel driver development is identical plumbing work for every company that has to do it. Owning it doesn’t make your product better; it just means you spent five years and eight million dollars on infrastructure your customers will never see. The companies that win in security are the ones that deploy detection capability faster than their competitors, not the ones with the most in-house kernel engineers.
What happens if Heathen goes away? We’d be dependent on a vendor.
A fair concern, and one worth taking seriously. Two things worth knowing: first, the license terms include a perpetuity clause — installs active during a subscription term keep running even if the subscription lapses. You are not held hostage. Second, the alternative — building it yourself — carries its own dependency risk: you become dependent on the 2–3 people on your team who understand how the kernel code works. When one of them leaves, you have a knowledge cliff. Which single point of failure would you rather manage?
Can’t we just use an open-source solution or an existing framework?
Some open-source kernel telemetry projects exist. The ones worth evaluating are either research-quality (not production-safe, no support, no signing), built for a different use case than yours, or no longer actively maintained. Production-signed kernel drivers — required to load on any current Windows system with Secure Boot enabled — are not something you get from a GitHub repo. Driver signing requires a registered EV code-signing certificate, submission to Microsoft’s hardware partner portal, and ongoing compatibility maintenance. Heathen handles all of that.
We already have engineers who could probably build this.
Probably is doing a lot of work in that sentence. Kernel development has a steep failure mode: bugs that don’t surface until month eighteen, under specific hardware configurations, that manifest as a BSOD on a customer machine. The first sign that your kernel code has a problem is often a production incident. Meanwhile, the engineers who “could probably build this” are engineers who could definitely be building the things that grow your business. The Heathen SDK was built specifically because this problem is not unique to your company — it’s the same work, done the same way, for every company in this space.
How do we know this is production quality and not someone’s side project?
Download the demo and run it. The installer is an MSI with production-signed drivers. The driver stack passes Driver Verifier with no pool leaks, no IRQL violations, and no race conditions under load — the same tests Microsoft uses to certify drivers for distribution. The SDK was built by a principal engineer with 15+ years of Windows kernel development experience on commercial security products. There is a working demo with a free evaluation license precisely so you don’t have to take anyone’s word for it.
Risk Comparison

Where the Risk Actually Lives

Every technology decision carries risk. The question is which risks you’re taking on and whether they’re the right ones for your business.

Risk Build It Yourself Heathen SDK
Time to market High — 3–5 years before telemetry is reliable enough to build on Low — prototype in a day; production-ready from day one
Windows compatibility High — your team owns every Patch Tuesday regression, indefinitely Low — compatibility maintenance is included in the license
Key-person dependency High — kernel expertise concentrates in 1–2 people; departure is painful Low — SDK consumers need no kernel expertise at all
Production incident (BSOD) High — kernel bugs can take months to surface and minutes to destroy customer trust Low — battle-tested driver stack; issues are vendor’s problem to fix
Vendor dependency None Managed — perpetuity clause; existing installs keep running on lapse
Budget predictability Low — headcount and timeline overruns are near-certain High — fixed annual licensing fee, no surprise costs
What the Decision Looks Like

With and Without the SDK

Without Heathen

  • 3–5 years of kernel engineering before detection work begins
  • Hiring 3–5 kernel engineers in a thin talent market
  • Every Patch Tuesday is your team’s problem
  • Driver signing certificate, WHQL process, hardware partner portal
  • First production incident surfaces a kernel bug your team has to debug at 2am
  • Engineers who could be building your product are building infrastructure

With Heathen

  • Receiving structured kernel events on day one
  • Detection logic, response actions, and customer features from sprint one
  • Compatibility maintenance included; Patch Tuesday is someone else’s problem
  • Production-signed drivers, no hardware partner portal required
  • Free evaluation — install the demo before committing to anything
  • Engineers focused on the work that earns the deal
Next Steps

Evaluate Before You Decide

The dev kit is free. No contract, no negotiation, no time limit. Your engineer can install it, build a prototype, and put real kernel telemetry in front of you before any commercial conversation happens. If it works for your use case, the licensing conversation is straightforward. If it doesn’t, you’ve lost an afternoon, not a year.

There is also a signed demo installer that shows a complete working EDR — detection rules, web dashboard, alert feed — built entirely on the SDK. You can run it on any Windows 10 or 11 machine today.
