Spreadsheets vs. ISMS Portal

Why Excel Is a Risky Way to Run Your ISMS (and What to Do Instead)

Many organizations start their ISMS journey the same way.

  • An Excel sheet
  • A shared drive
  • A few reminder emails

At first, it works.

Then the ISMS grows. Audits approach. People change roles. Versions multiply.

Suddenly, Excel becomes the biggest risk in your compliance program.

Spreadsheets are great for calculations. They are not built for governance.
ISO standards reward consistency, traceability, and proof.

Why so many ISMS programs still rely on spreadsheets

Spreadsheets feel easy.

  • They’re familiar
  • They’re flexible
  • They’re already there

But ISO standards don’t fail because teams lack effort.
They fail because manual tools don’t scale.

The hidden risks of managing an ISMS in Excel

1) Version confusion

  • Multiple copies of the same file
  • “Final_v7_reallyfinal.xlsx”
  • No single source of truth

Auditors ask: Which one is approved? Teams hesitate. That’s a red flag.

2) No automated reminders

Spreadsheets don’t remind you when:

  • Policies are due for review
  • Risks need reassessment
  • Access reviews are overdue

Compliance becomes memory-based. That never ends well.

3) Human error is guaranteed

Manual updates lead to:

  • Missed controls
  • Incomplete evidence
  • Incorrect dates
  • Accidental deletions

In ISO audits, “we forgot” is not a defense.

4) Limited collaboration

Excel doesn’t support:

  • Controlled co-authoring
  • Approval workflows
  • Role-based access
  • Clear ownership

As more teams get involved, coordination breaks down.

5) Audits become painful

Auditors don’t want spreadsheets. They want:

  • Evidence history
  • Approvals
  • Traceability
  • Accountability

With Excel, audits turn into scavenger hunts.

Stressful audits Audit-ready by design

Why an automated SharePoint ISMS portal works

A SharePoint-based ISMS portal provides:

  • One authoritative source of truth
  • Automated review and approval workflows
  • Built-in version control
  • Continuous evidence tracking
  • Native Microsoft 365 security

Compliance becomes operational not reactive.

Where vCISO support makes the difference

Tools alone don’t fix governance.

A vCISO helps you:

  • Design the ISMS correctly
  • Decide what to automate first
  • Align SharePoint workflows to ISO 27001 / 27017 / 27018
  • Avoid over-engineering

What auditors see when you leave Excel behind

Auditors immediately notice when an ISMS is portal-based:

  • Clear ownership
  • Consistent processes
  • Reliable audit trails
  • Mature governance

Audits move faster. Questions decrease. Confidence increases.

Final thought

Spreadsheets are great for calculations.

They are terrible for governance.

If your ISMS still lives in Excel, the risk isn’t if something gets missed it’s when.

Automation isn’t about convenience. It’s about control, confidence, and compliance.

Build your ISMS on a platform designed for audits

Replace “spreadsheet governance” with a system that stays current.
