Managing the Risks of Microsoft Office Files
Northern now gives organizations complete visibility into the hidden dependencies and threats of old and new-format Office files.
Protect Critical Business Processes
In many organizations, business-critical workflows are built around Office files, particularly Excel. These processes have typically evolved over many years, creating a network of hidden dependencies; reliance on legacy file formats, links between files, and embedded macros. When files are moved, archived, deleted, or migrated, these dependencies are broken, leading to costly operational disruptions, incorrect results, and flawed business decisions.
Northern now gives organizations complete visibility into their ecosystems of Microsoft Office files.
Identify risks by cataloguing macros and revealing links between files. Make informed decisions during activities such as data cleanup, restructuring, migration, and permissions hardening. Implement changes without blindly disrupting critical business processes.

The Challenges with Office Files
The Challenges with Office Files
- Older Office file formats (xls, doc, xlsm) contain documented security vulnerabilities.
- Macros in these files are known attack vectors.
- Older formats will eventually stop being usable, destroying workflows that depend on them.
- Critical workflows that rely on files that are linked to one another.
- Macros drive complex calculations and processes that are often undocumented.
- Removing or moving a single file without understanding these links can silently break workflows.
- Reorganizing folders or migrating files without understanding dependencies risks breaking critical workflows.
- Organizations may delay modernization projects due to fear of disrupting business-critical processes.
- Legacy folder structures and hidden file dependencies force teams to work around inefficiencies.

Six Situations Where Visibility is Critical
Six Situations Where Visibility is Critical
2-1
Data Decommission & Cleanup
Data Decommission & Cleanup
You’re running a campaign to clean up legacy data. You have defined criteria based on file ownership, type, and age. Many tens of thousands of files are targeted, and the storage infrastructure team is eagerly anticipating the positive results.
A key step in your planning is to analyze the Office files involved, to identify whether any current processes depend on the files you are targeting. Deleting files without this visibility can silently break critical workflows, for example:
- Monthly reporting templates pulling data from perpetual reference files
- Budget spreadsheets linked to master files created when processes were first implemented
- Sales dashboards or commission calculations that pull figures from multiple historical files
Northern now identifies dependencies, allowing you to safely archive or remove files without disrupting operations.

Removing Risk & Futureproofing
Removing Risk & Futureproofing
You are focused on staying ahead of evolving security threats, protecting your organization from malicious actors, and ensuring that critical business processes remain resilient. Updating outdated or unsupported Office files is a necessary part of this effort.
Old-format Office files carry significant, well-documented security and operational risks:
- Their binary formats are inherently complex, making them prone to exploitable bugs in their parsers.
- They can embed macros or other executable instructions that are easily abused, making them attractive vectors for attackers.
- They are increasingly unsupported: Microsoft already prevents them from being opened directly in M365, and Microsoft’s security baselines have long steered organizations towards blocking these formats entirely.
These are compelling reasons to retire legacy formats and update important documents to their modern equivalents: protect your business from malicious actors and protect your business processes from the inevitable march of time.
Northern now identifies these files and highlights the risks, allowing organizations to reduce exposure, modernize critical documents, and maintain business continuity.

Discover Hidden Processes
Discover Hidden Processes
You want to understand how your organization actually works. Over time, users have built complex workflows in Excel and other Office files that are undocumented and hidden from IT and management. Gaining this insight is critical for:
- Documenting and standardizing critical processes to reduce risk
- Modernizing outdated methods to improve efficiency
- Transferring knowledge from key individuals to ensure business continuity
Without visibility, you risk breaking hidden processes or leaving them undocumented, making modernization, risk management, and knowledge transfer impossible.
Northern now maps these connections, enabling you to document, protect, modernize, or retire these processes safely.

Restructuring, M&A, Organizational Change
Restructuring, M&A, Organizational Change
Your organization is undergoing a merger, acquisition, or internal restructuring. It is an opportunity to realign your file system with your new business structure and improve operational efficiency.
Hidden links and macros in Office files make it difficult to reorganize folders or rename files safely. Without visibility, decision-makers face two risky choices:
- Keep the old, inefficient structure, forcing teams to struggle with workarounds
- Reorganize blindly, risking broken workflows and operational disruption
Northern now provides a third option: map dependencies before restructuring and act accordingly, enabling smooth change without operational disruption.

Migration to Cloud / M365
Migration to Cloud / M365
You’re preparing to migrate your file storage to Microsoft 365 to improve collaboration, reduce on-premises overhead, and modernize your IT environment.
Relationships and dependencies between Office files pose a real problem in this scenario. Links between files rely on exact folder and file names—names that often cannot be mirrored in M365, breaking these relationships and the workflows that depend on them.
Old-format Office files add another layer of risk. They can be stored in M365 sites, but they must be updated when opened for the first time, creating further reason to clean up and modernize your Office file ecosystem as part of the migration. Without this preparation, you risk:
- Reports or dashboards producing incorrect or incomplete data because the underlying processes have been broken
- Users encountering files that cannot be opened or behave unpredictably
- Duplicate and outdated files cluttering the system, increasing storage costs, reducing efficiency, and negatively affecting user experience
Northern now identifies unsupported or risky files and maps their dependencies, helping organizations convert or modernize files safely while preserving workflow integrity.

Operational Efficiency and Governance
Operational Efficiency and Governance
You’re focused on improving operational efficiency, strengthening governance, and ensuring workflows are reliable and resilient. This is a criteria for success in any organization. Being reactive, however, means investing time and resources just to recover lost ground when processes fail or inefficiencies accumulate. Taking a proactive approach allows you to invest in real progress: streamlining workflows, removing redundant systems, and implementing governance that drives lasting improvement.
Without visibility into interlinked or macro-enabled Office files, you cannot confidently clean up, reorganize, or modernize workflows. Hidden dependencies increase inefficiencies, slow decision-making, and raise IT overhead.
Northern now provides a complete view of file dependencies, enabling organizations to improve efficiency, reduce costs, and implement proactive governance for Office files.

Conclusion
Office files may seem simple, but they often underpin the most critical business processes. Hidden dependencies, legacy formats, and outdated workflows create risk, inefficiency, and operational friction.
Northern now gives organizations the visibility and insight they need to manage these files proactively – safely decommissioning legacy data, modernizing processes to remove risk, and migrating to the cloud with confidence.
Proactive governance of Office files is not optional; it’s a strategic enabler of secure, efficient, and resilient business operations.
