From Spreadsheet to BCMS: Why Excel No Longer Cuts It in 2026
With NIS2 and DORA, immutable audit trail, secure multi-user and real-time cartography are no longer optional. Here's why Excel becomes a risk, and how to migrate in 2 weeks.
6 spreadsheet BCMS limits in 2026
What worked for 20 assets no longer holds at 200.
Security and encryption
Excel and Sheets store in clear, no HSM, no customer-managed key. BCM data contains risk mapping, critical suppliers, RTO/RPO — this is sensitive data.
Fragile concurrent editing
At 5+ contributors, version conflicts explode. Parallel versions 'v3-final-real-FINAL' on network shares. One loss = one month of work.
No relations between objects
Mapping process → app → supplier → risk → CIF requires dozens of tabs and VLOOKUPs. One change = manual update everywhere.
No time-based workflow
NIS2 enforces 24h / 72h / 1month. A spreadsheet triggers no alert, no reminder, no timestamped decision trail.
No audit trail
No way to prove to an ANSSI/ACPR auditor who wrote what, when, why. Compliance requires immutable evidence.
No real-time cartography
Impossible to visualize the dependency chain or simulate a cut. For an SME in a crisis, that's a deal-breaker.

Frequently asked questions
Is my Excel BCMS really non-compliant?
Excel is not forbidden, but it makes NIS2/DORA compliance demonstration very hard: audit trail, review dates, signatures, secure multi-user. An ANSSI or ACPR auditor demands immutable timestamped evidence that Excel cannot provide natively.
How long to migrate from Excel to ResiPlan?
2 to 4 weeks for an SME of 50–250 staff. The import wizard accepts CSV/Excel and AI enriches missing fields. Initial BIA deliverable in 2 hours.
Isn't the cost higher than Excel?
Apparent Excel cost = €0, but actually 50–100 person-days/year in maintenance (consolidation, version conflicts, manual lookup). ResiPlan at €3,600/year = 5 person-days saved. Positive ROI within Q1 for most SMEs.
How does ResiPlan protect my data vs Sheets / Microsoft 365?
ResiPlan is hosted exclusively at OVHcloud in France (Roubaix/Gravelines), with SecNumCloud V2 qualification in progress. Your data does not leave the EU, escapes the US Cloud Act, and at-rest encryption uses HSM keys. Sheets and M365 store in the US with partial EU replication.
What if I want to go back to Excel one day?
Complete JSON / Excel / PDF export of all your artifacts in 1 click. No lock-in. Your data remains yours.
Is ResiPlan suitable for SMEs or only large groups?
ResiPlan is primarily designed for European SMEs and mid-caps (50 to 5,000 staff). Unlike Riskonnect or Archer platforms built for 5+ FTE GRC teams, ResiPlan works for a lone BCM Manager, thanks to AI and pre-wired templates.
