When’s the last time you cleaned out your digital closet? If you’re like most people, the answer is somewhere between “never” and “what is a digital closet?” We’ve become information hoarders in an age of seemingly unlimited cloud storage, keeping thousands of emails, photos, documents, and accounts we haven’t touched in years.

Your Old Data Files Are a Security Problem

Every data file you hold on to is a potential security liability. That long-forgotten account for a shopping website from 2016? It’s still sitting there with your personal information, payment details, and possibly even your address history. 1,000 emails in your inbox from six years ago? The folder with 10-years of tax returns? Safety scans of your driver’s license and credit cards? Folders with your kids’ birth dates and school details? Your notes with all your password hints? Each one is a potential entry point if your account is ever compromised.

This isn’t just digital clutter—it’s a silent security risk that most cybersecurity conversations overlook. Think for a minute what would happen if hackers got access to this information.

Email is NOT a File Storage System

Which reminds me of one of my pet peeves: Email is a communication system. It is not a file storage system. Email was created to facilitate the exchange of messages between individuals or groups. Its core function is communication. Email applications are not designed to serve as a long-term repository for files. Most email providers impose storage limits. And while email systems do offer search functions, they’re tailored for finding conversations or message subject lines. Trying to locate a specific PDF buried in a months-old email thread highlights this limitation. If you retain more than 1-month of email, you are open for disaster: both in terms of losing information and getting hacked (and losing even more information).

Hacker’s Can’t Steal What’s Not There

One of the most powerful security concepts I’ve encountered during my research for my cybersecurity book is the self-evident: data that doesn’t exist can’t be stolen. Cybersecurity professionals call this “data minimization,” and it might be the most underrated security practice available to everyday users.

Think about it this way: if a hacker gains access to your email account, what could they find? Contracts? Divorce papers? Birthday and anniversary dates? Password reset links? Verification codes? Sensitive conversations? Instructions to access a will from a Nigerian prince worth millions?

For many of us, our email accounts are like digital attics filled with years of personal information we’ve forgotten about but never bothered to clean up.

Digital Decluttering in Three Steps

  1. Account Audit: Start by making a list of all your online accounts. (Hopefully, all of your accounts are stored in a password manager.) This alone can be eye-opening—most people have far more than they realize.Once you have your list, ruthlessly evaluate each account: Do you still use this service? Does it still provide value? Does it store sensitive information like payment details or personal data? For accounts you no longer need, don’t just abandon them—properly close them. Many services have an “Account Deletion” option in settings. For those that don’t, contact customer support.
  2. Purge Old Emails: Your inbox is likely a treasure trove of sensitive information. Consider:
    • Archiving or deleting emails older than a certain date. (I don’t keep emails older than 6-weeks.)
    • Setting up an automated system to delete emails after a certain period.
    • Creating separate email accounts for different purposes (shopping, financial, work, personal).
    • Using search operators to find and bulk-delete sensitive content (try searching for “tax,” “SSN,” “password,” or “account number”).

    Maybe you’re an attorney or an accountant, and you need to retain emails for several years. Most email clients have the ability to export emails as archives (or, plugins are available for that purpose). Export them and archive them in a password protected vault.

  3. Storage Sweep: Finally, turn your attention to files and photos:
    • Review cloud storage accounts (Google Drive, Dropbox, iCloud) for sensitive documents.
    • Check your downloads folder—it’s often a forgotten repository of sensitive files.
    • Consider offline storage for truly sensitive documents instead of keeping them perpetually in the cloud.
    • Delete or secure old photos that might contain personally identifiable information (like photos of your ID or mail).

Unexpected Benefits

Besides the obvious security advantages, there are surprisingly positive side effects to digital decluttering:

  • Mental clarity: Less digital noise means less cognitive load
  • Faster searches: Finding what you need becomes easier
  • Storage savings: You might be paying for storage you don’t need
  • Privacy improvement: Fewer data points about you exist in the digital world

Data Deletion—Make it a Strategy, not a Tactic

The key to making this work isn’t a one-time purge but developing sustainable habits:

  • Schedule quarterly “digital cleanup days” on your calendar
  • Create a simple system for evaluating whether to keep new accounts or data
  • Adopt the “if in doubt, throw it out” mentality for digital assets
  • Consider using ephemeral services that automatically delete data after a certain period

In Summary

In a world obsessed with adding more security layers, sometimes the most powerful move is subtraction. By thoughtfully reducing your digital footprint, you’re not just organizing—you’re actively strengthening your security posture.

I’ve found that this minimalist approach to digital security aligns perfectly with what I’m exploring in my upcoming book—effective security doesn’t always mean adding complexity. Sometimes it means stepping back and asking, “Do I really need this?”
