ScopeSense vs the MITRE ATT&CK Navigator
The ATT&CK Navigator is a free, open-source tool for viewing and annotating ATT&CK layers. ScopeSense's MITRE ATT&CK Coverage module is a paid assessment that builds the scored layer from a detection rule export and an environment inventory, then exports a Navigator layer as one of its outputs. The two are complementary, not competing: this page explains why.
Every Navigator claim below is quoted or paraphrased from the project's own GitHub repository and its hosted documentation as they read on 2026-09-12. Where a capability is not part of its documented feature set, the cell says so rather than guessing at what a general-purpose visualization tool might also happen to do.
The comparison
| Criterion | ATT&CK Navigator | ScopeSense |
|---|---|---|
| What it is | A free, browser-based visualization and annotation tool for the ATT&CK matrix. Its own documentation describes it as providing "basic navigation and annotation of ATT&CK matrices." | A coverage-assessment pipeline: you upload a detection rule export and an environment inventory, and it produces a scored, evidenced assessment. |
| How the data gets in | A "layer" — the file Navigator visualizes — is either "created interactively within the Navigator or generated programmatically," including via example scripts in its repository. Either way, someone has to build it. | The rule export and environment inventory are ingested directly. Applicability is decided per technique, and every "not applicable" call carries a printed reason rather than a blank cell. |
| Applicability and gaps | Not stated publicly as a Navigator feature; it visualizes whatever scores or colors a layer file already contains. | A tagging ladder and detection-strength score per technique, ranked gaps, and a roadmap ordered by what closes the most exposure first. |
| Deliverables | The layer itself, viewed or exported inside the tool. Report generation such as PDF, XLSX or PPTX is not part of its documented feature set. | PDF (executive and detailed), an XLSX tracker with reference detection queries, an 18-slide PPTX, and — because Navigator is the standard viewer for this data — a Navigator layer file generated from the same assessment. |
| Cost and license | Free and open source, Apache License 2.0. | Quote-based; the assessment is the paid product, not the layer visualization. |
Where the Navigator still wins
Navigator is free, runs entirely in a browser (or self-hosted), and needs no data upload of any kind — a red team or blue team can sketch a layer by hand in minutes for a one-off exercise, which is more than ScopeSense's pipeline is built for.
It is also the tool most ATT&CK content already targets: threat intel reports, other vendors' overlays and community layers are commonly shared as Navigator files. That is exactly why ScopeSense exports one — an assessment that could only be opened in ScopeSense's own viewer would be less useful to a team already living in Navigator.
Coverage percentages, from either tool, describe presence of a detection, not its efficacy against a live intrusion — that caveat applies to a hand-built layer as much as a generated one.
Where the assessment is measured
A deterministic pre-pass over the rule export cuts the AI tagging calls needed to reach a scored layer by 63%, with zero false positives introduced by that pre-pass (ScopeSense engineering measurement). The product page covers the full ingest-to-roadmap pipeline.
How to decide
If a layer already exists — from a red-team exercise, a vendor's threat report, or a colleague's manual annotation — and the job is to view or lightly edit it, the Navigator is free and already does that well. If the job is building that layer in the first place from a real rule export and a real environment, with applicability reasons a reviewer can check, ranked gaps and a roadmap, and exports beyond the layer file itself, that is a different job, and it is the one ScopeSense's assessment does. Most teams end up using both: ScopeSense to generate the scored layer, the Navigator to view and share it alongside everything else already in that format.
FAQ
Is ScopeSense trying to replace the ATT&CK Navigator?
No. Navigator is the standard way to view and share an ATT&CK layer, and ScopeSense exports one from every assessment so the result opens there too. They solve different problems: Navigator visualizes a layer you already have; ScopeSense builds the scored layer from your raw rule export.
Can I still open a ScopeSense assessment in the Navigator?
Yes. Every assessment includes a Navigator layer export alongside the PDF, XLSX and PPTX outputs.
Does ScopeSense need my raw logs or SIEM data?
No. It ingests your detection rule export and an environment inventory you provide; it does not require log or telemetry access.
How is a technique marked not applicable?
Applicability is decided per technique against your stated environment, and every N/A call is printed with the reason, so a reviewer can check the assumption rather than take a blank cell on faith.
