01
Four management systems on one data model — not two plus two engagements
Proliance 360 genuinely connects ISMS and data protection through a shared Asset Hub, Docu Hub and Control Hub. For ISO 22301 (business continuity) and ISO 42001 (AI management system), Proliance offers consulting engagements with a defined phase plan by its own account, but no software module visibly sharing assets, risks and controls with the other two systems. In KaitoSec, ISMS, BCMS, DSMS and AIMS share the same assets, risks and controls from day one.
02
The risk module is not live yet
Proliance 360's Risk Hub — the module for structured risk identification and assessment — is marked 'Bald verfügbar' (coming soon) on the vendor's own feature overview as of September 2026. That leaves out, in the product as shipped today, exactly the piece that ISO 27001 clause 6.1.2, NIS2 Article 21(2)(a) and the risk-based TOMs under GDPR Article 32 all require. KaitoSec runs a native risk register tied to assets and controls now.
03
On-premise, where data cannot go to the cloud
Proliance operates Proliance 360 as cloud SaaS only; no on-premise option appears anywhere on its site. For suppliers to public authorities or KRITIS-adjacent mid-market companies barred from placing security data in third-party cloud infrastructure, that ends the evaluation before any feature comparison starts. KaitoSec offers on-premise deployment in the Enterprise plan.

BSI IT-Grundschutz: claimed, but not shown on the product pages
A comparison article on Proliance's own blog lists BSI IT-Grundschutz among its covered standards. The actual product pages — the ISMS software page and the Control Hub — name only ISO 27001, NIS2, GDPR and TISAX as covered frameworks, and an independent market overview lists Grundschutz as explicitly missing. Anyone who needs Bausteine and Schutzbedarf mapped under BSI standard 200-x should confirm this directly with Proliance before shortlisting. KaitoSec carries the Grundschutz Bausteine as a full framework in the same data model as ISO 27001 and NIS2.
05
Several price lines instead of two
Proliance publishes list prices, which is transparent and rare in this market. But buyers who need ISMS, data-protection software and consulting together add up several parallel line items: ISMS software from €500/month (Light) or €1,000/month (Core), a consulting package from €1,000/month in year one, optionally the data-protection software from €118/month, and a GAP analysis from €2,880. KaitoSec shows platform and advisory as two separate lines in the proposal.
