SharePoint ISMS vs. SaaS GRC Platforms

Which Compliance Platform Is Right for You?

Choosing an ISMS or GRC platform is no longer just a tooling decision.

It’s a governance decision.

Where does your most sensitive compliance data live? Who controls it? How flexible is the platform when your business changes?
For many organizations, the comparison comes down to two options:

  • A SharePoint-based ISMS inside Microsoft 365
  • A third-party SaaS GRC platform

Both promise compliance. But they work very differently.

This decision affects data ownership, audit speed, and how much your team will rely on spreadsheets when pressure hits.

Why this decision matters more than ever

Modern ISMS programs manage:

  • Risk registers
  • Incident records
  • Audit evidence
  • Policies and procedures
  • Access reviews and approvals

This data is highly sensitive. Where and how it’s stored matters—to auditors, customers, and regulators.

At a glance: SharePoint ISMS vs SaaS GRC

SharePoint ISMS SaaS GRC platform
Built inside your Microsoft 365 tenant
Full data ownership and control		 Hosted externally by a third party
Compliance data lives outside your environment
Native M365 workflows (Teams + Power Automate) Separate tool, separate UX, separate adoption cycle
Flexible structure that can evolve with your ISMS Opinionated workflows that may require adaptation

That first row (where your compliance data lives) drives almost everything else.

1) Data ownership and control

SharePoint ISMS (Microsoft 365)

  • Data stays inside your tenant
  • You control access, retention, and residency
  • Aligned with your existing security controls
  • Easier to answer “where is our data stored?”

This is a major advantage during audits and vendor risk reviews.

SaaS GRC platforms

  • Compliance data is hosted externally
  • Data residency may be unclear
  • You inherit the vendor’s security posture
  • Auditors often ask additional questions

For some organizations, this is a deal-breaker.

2) Integration with daily work

A SharePoint-based ISMS fits naturally into how teams already work:

  • Native Word, Excel, and PDF support
  • Teams notifications and approvals
  • Power Automate workflows
  • Familiar interface

Adoption is faster because users don’t feel like they’re “learning another tool.”

SaaS GRC platforms often introduce friction:

  • Separate login and interface
  • Limited customization
  • Often require training
  • Risk of becoming a “compliance-only” system

If people don’t use the platform, it won’t stay current.

3) Cost and long-term scalability

SharePoint ISMS SaaS GRC platform
Leverages existing Microsoft 365 licenses Per-user or per-module pricing
No per-user SaaS pricing shock Costs increase as teams grow
Lower long-term total cost of ownership Add-ons often required for advanced features
Scales with your organization Vendor lock-in risk

The initial SaaS price may look attractive—until scale kicks in.

4) Flexibility and customization

SharePoint ISMS

  • Customizable structure
  • Tailored to ISO 27001, 27017, 27018, SOC 2
  • Adapts to your processes
  • Supports hybrid and evolving compliance needs

Ideal for organizations with unique workflows.

SaaS GRC platforms

  • Opinionated workflows
  • Limited customization
  • “One-size-fits-most” approach
  • Harder to adapt to real-world audits

Flexibility becomes critical as standards evolve.

5) Audit experience (the part that really matters)

Auditors don’t care about dashboards. They care about:

  • Evidence
  • Version history
  • Approvals
  • Ownership
  • Traceability
SharePoint ISMS SaaS GRC platform
Clear document history and native version control Evidence often uploaded manually
Structured evidence libraries and metadata Context can get lost between fields/uploads
Easy auditor access (read-only) if needed Auditors may not know the tool
Audits feel familiar and transparent Exports can be painful under time pressure

The audit experience is where the “real value” shows up especially when timelines are tight.

When a SaaS GRC platform does make sense

To be fair, SaaS GRC platforms can work well when:

  • You have no Microsoft 365 environment
  • You want a very prescriptive framework
  • You don’t need deep customization
  • You accept external data hosting

They are not “bad” tools. They’re just not right for everyone.

When a SharePoint ISMS is the better choice

A SharePoint-based ISMS is ideal if you:

  • Already use Microsoft 365
  • Want full control over compliance data
  • Need flexibility across ISO and SOC frameworks
  • Prefer native integration over another SaaS

For many Canadian organizations, this is the more natural fit.
