IT-Grundschutz
SentryAssets guides you step by step through the IT-Grundschutz of the German Federal Office for Information Security (BSI), even without a security officer of your own. The basis is your inventory: the inventory is the structure analysis. You do not record assets, locations and relations a second time.
Choosing the variant
Section titled “Choosing the variant”SentryAssets supports both variants of the IT-Grundschutz. Under IT-Grundschutz an overview compares them.
| Grundschutz++ | Edition 2023 | |
|---|---|---|
| Structure | 20 practices, such as governance, configuration or detection; requirements refer directly to target object categories | modules in layers (ISMS, applications, IT systems, networks, infrastructure), assigned to the target objects during modelling |
| Scope | about 1,000 requirements with MUST, SHOULD or MAY, each with a security level (normal or elevated) and an effort from 0 to 5 | more than 100 modules with basic, standard and requirements for high protection needs |
| Format | machine-readable (OSCAL), updated continuously | Kompendium as PDF and XML in yearly editions |
| Method | method guide of April 2026, still being trialled | BSI Standards 200-1 to 200-3 with basic, standard and core protection |
| Certification | expected from 2027 | ISO 27001 based on IT-Grundschutz, expected until the end of 2028 |
| Suited for | a start without earlier Grundschutz documentation, aiming at the coming version | anyone seeking a certificate now or continuing existing documentation |
As of October 2026 according to the BSI; dates for certification and transition may change.
You download both catalogues from the BSI yourself and import them; SentryAssets checks the file completely before it stores it.
The BSI Standard 200-2 way

The page IT-Grundschutz shows where you stand and names the one next step. Under Tasks SentryAssets reminds of that step, for the roles that may take it.
-
Define the information domain. The information domain (Informationsverbund) covers all processes, applications, IT systems, rooms and people you look at together (BSI Standard 200-2, ch. 3.3). The dialog explains what belongs to it and proposes a name and scope. For Grundschutz++ you choose security level and modality, for Edition 2023 the approach (basic, standard or core protection); to start with, the dialog recommends basic protection.
-
Structure analysis from the inventory. The target objects (Zielobjekte) come from your inventory: the information domain itself, categories as groups of similar assets, single assets and locations. For Grundschutz++ SentryAssets proposes the target object categories from inventory and locations.
-
Determine the protection requirements. Per security goal (confidentiality, integrity, availability) you set the protection requirement (Schutzbedarf): normal, high or very high. Locations follow the maximum principle: per goal the highest value of the assets there (BSI Standard 200-2, ch. 8.2). With Pro SentryAssets inherits protection requirements along the dependencies.
-
Model. For Edition 2023 SentryAssets proposes modules from the category, the operating systems the agents report and the kind of location, each with its reason; you take them over one at a time or assign others by search. For Grundschutz++ the requirement package follows from the information domain. With Pro you take every proposal over at once.
-
Set parameters (Grundschutz++). Some requirements contain parameters, such as a deadline. Each parameter says what kind of value is asked for, with fitting proposals; your values are kept across new catalogue versions and appear in the requirement texts.
-
Grundschutz check. Per requirement you record the state: implemented, partly, not implemented or not applicable (only with a reason), plus responsible person, due date and note. A legend says when each answer is right; each Grundschutz++ requirement explains its text with your values, the expected result and suitable evidence.
-
Link evidence. Documents that show an implementation, such as the management’s decision, are attached to the state of a requirement, existing ones or uploaded right away. A document’s page shows what it serves as evidence for.
Progress and due dates
Section titled “Progress and due dates”- The overview shows progress per practice or module and target object.
- Due and overdue dates appear as tasks.
- Export the requirement package with its implementation state as CSV.
- Entries whose requirement or parameter a newer catalogue no longer contains can be removed.
Example: RECPLAST GmbH
Section titled “Example: RECPLAST GmbH”RECPLAST GmbH is the BSI’s example company. In SentryAssets its way could look like this:
- Information domain “RECPLAST overall” with the head office and the production site as locations, basic protection.
- The agents discover servers and clients; the collector finds printers and switches. The categories “Server”, “Clients” and “Network” become target objects.
- The file server gets protection requirement “high” for confidentiality, as design data are stored there; the head office takes this value over by the maximum principle.
- SentryAssets proposes the matching modules for the Windows servers and the module for server rooms for the server room.
- In the Grundschutz check the security officer attaches the approved backup concept as evidence.
Further reading
Section titled “Further reading”- The ISMS add-on adds the policy, risk analysis after BSI Standard 200-3, the implementation plan and the reference documents A.0 to A.6.
- Approvals in the Grundschutz check after the four-eyes principle (Pro).
- The AI assistant answers questions on the Kompendium with sources.
