KaitoSec vs QSEC
QSEC comes from the KRITIS side and carries ISMS, BCM and data protection. KaitoSec adds ISO 42001, SOC 2 and the EU AI Act on the same data, so AI governance and international customer requirements do not become a project of their own.
QSEC
QSEC is the GRC and ISMS suite from Nexis GRC GmbH in Hamburg, in the market since 2008. It covers ISO 27001, BSI IT-Grundschutz, B3S and data protection, and its BCM module implements ISO 22301 and BSI-Standard 200-4 including business impact analysis.

| BSI IT-Grundschutz | Yes | Yes |
| ISO 27001 | Yes | Yes |
| GDPR | Yes | Yes |
| ISO 22301 | Yes | Yes |
| B3S sector-specific security standards | Yes | Yes |
| NIS2 under the German implementation law | Yes | Partial |
| ISO 42001 (AIMS) | Yes | No |
| SOC 2 | Yes | No |
| EU AI Act | Yes | No |

When KaitoSec can be a good fit
Frameworks beyond the German core
QSEC covers the German core well. KaitoSec carries ISO 42001 as an operated AIMS, SOC 2 for international customers and the EU AI Act, whose Article 50 transparency duties have applied since August 2026, on the same data model as the ISMS.
The switch as a named service
A move out of a grown suite follows a fixed shape: export of the control register, the risk register and the policy library, a mapping pass onto the KaitoSec model, an evidence import for the historical audit trail, then a parallel period in which the old system stays read-only. Surveillance audits and management reviews continue while that runs.
Drafts on every record
KaitoSec puts Cmd+J on every record and drafts risk treatments, policy sections, audit answers and BC plans from the live workspace context, with Simple Mode for occasional contributors and Expert Mode for the security officer. The framework still drives the work; KaitoSec AI shortens the path to a draft that holds up.
When QSEC can be a good fit
A catalogue grown on the KRITIS side
QSEC has served ISMS, BCM and data protection for regulated operators since 2008, with B3S and BSI-Standard 200-4 built in from that practice. Where your audit runs against a sector standard and the assessors already know the tool, that history counts.
Familiar workflows for existing users
Teams that have run QSEC for years have built processes, documentation templates and audit trails around it. Where retraining, data migration and process change outweigh what a move would gain, staying put is a legitimate decision for at least one more audit cycle.
FAQ
How difficult is it to migrate from QSEC to KaitoSec?
The difficulty sits in the mapping, not in the export. Control register, risk register and policy library come out of QSEC in a structured form; what takes the work is deciding how each entry lands in the KaitoSec model. That mapping pass is a named service in the engagement, and its result is agreed before anything is imported.
Will we lose our audit history if we switch?
No. Historical compliance data, evidence records and risk assessment history can be imported, and each imported item keeps its source, timestamp and version. That is what makes an old record usable in front of an assessor after the migration rather than merely archived.
Does KaitoSec require a long implementation project?
The plan follows your scope, data quality, integrations and approval model. KaitoSec starts from guided templates and a structured import, and the concrete timeline is agreed for your organisation rather than promised as a blanket number.
Does QSEC cover B3S better than KaitoSec?
QSEC has carried B3S from its KRITIS practice for years. KaitoSec maps B3S onto the same control model as BSI IT-Grundschutz and NIS2, so a control implemented once answers all three. Ask both vendors to show the mapping against the sector standard that applies to you, and judge on that rather than on the catalogue entry.
