How to Handle Sensitive Company Data Securely

📌 What is Considered Sensitive Company Data?
Sensitive data includes any confidential, proprietary, or regulated information, such as:
✔ Customer & Employee Information – Names, addresses, Social Security numbers, payroll details.
✔ Financial Records – Bank account details, invoices, tax records.
✔ Intellectual Property – Trade secrets, product designs, research data.
✔ Business Strategies – Internal reports, legal contracts, marketing plans.
✔ Login Credentials & Access Codes – Usernames, passwords, API keys.
✅ If data could harm your business or clients if exposed, it must be protected!
📌 Best Practices for Securing Company Data
1. Encrypt All Sensitive Data
✔ Use encryption for files, emails, and stored data to prevent unauthorized access.
✔ Enable BitLocker (Windows) or FileVault (Mac) to encrypt devices.
✔ Use secure cloud storage with end-to-end encryption (e.g., Microsoft OneDrive, SharePoint).
✅ Encryption ensures that even if data is stolen, it remains unreadable!
2. Use Strong Passwords & Multi-Factor Authentication (MFA)
✔ Create unique, complex passwords (at least 16 characters with numbers & symbols).
✔ Use a password manager (Keeper Security) to store and autofill credentials securely.
✔ Enable MFA (Microsoft Authenticator, Google Authenticator) for all accounts.
✅ MFA adds an extra layer of security, preventing hackers from logging in!
3. Restrict Access to Sensitive Data (Least Privilege Principle)
✔ Only grant employees access to data necessary for their job role.
✔ Use Role-Based Access Control (RBAC) to limit permissions.
✔ Regularly review and remove access for employees who no longer need it.
✅ Limiting access reduces the risk of accidental or intentional data leaks!
4. Securely Share & Store Files
✔ Use company-approved cloud services (OneDrive, SharePoint, Google Drive) for secure file sharing.
✔ Never send sensitive data over email or unencrypted messaging apps.
✔ Set expiration dates and restricted permissions on shared files.
✅ Cloud-based collaboration tools protect files with encryption and access controls!
5. Be Cautious with Email & Phishing Attacks
✔ Never open unexpected attachments or links from unknown senders.
✔ Verify urgent requests for money or confidential data via phone.
✔ Enable email filtering and anti-phishing tools (Microsoft Defender for Office 365, Mimecast).
✅ Phishing is one of the top causes of data breaches—always verify before acting!
6. Lock Devices & Use Secure Remote Access
✔ Lock your computer when away (Win + L on Windows, Command + Control + Q on Mac).
✔ Use VPNs (OpenVPN Connect v3) to securely connect to company networks.
✔ Enable automatic screen locks on mobile devices and encrypt company laptops.
✅ Unattended or unencrypted devices are easy targets for cybercriminals!
7. Properly Dispose of Sensitive Data
✔ Use secure file deletion tools to remove confidential documents.
✔ Shred physical documents containing sensitive company information.
✔ Wipe hard drives and devices before disposal (use DBAN or BitRaser).
✅ Deleted files can still be recovered—always use secure deletion methods!
8. Monitor and Audit Data Access
✔ Enable audit logs in Microsoft 365, Google Workspace, and cloud apps.
✔ Regularly review who accessed, modified, or shared sensitive files.
✔ Implement Data Loss Prevention (DLP) policies to stop unauthorized sharing.
✅ Tracking access helps detect suspicious activity before it becomes a breach!
9. Train Employees on Data Security Best Practices
✔ Conduct regular security awareness training on phishing, password hygiene, and secure data handling.
✔ Teach employees how to recognize suspicious emails and social engineering attacks.
✔ Establish clear company policies for handling sensitive information.
✅ Security awareness reduces human error—the #1 cause of data breaches!
10. Have a Data Breach Response Plan
✔ Identify who to contact (IT, legal, cybersecurity team) in case of a breach.
✔ Implement automated alerts for unusual account activity.
✔ Have a backup and disaster recovery plan to restore lost or stolen data.
✅ Being prepared can minimize damage and prevent prolonged downtime!
📌 What to Do If Sensitive Data is Leaked or Stolen
🚨 If a data breach occurs, take immediate action:
✔ Change affected passwords and revoke compromised access.
✔ Isolate infected devices to prevent further spread.
✔ Notify affected customers or employees (if required by law).
✔ Contact IT support or a cybersecurity expert for incident response.
✔ Review and improve security policies to prevent future incidents.
✅ A quick response can prevent financial and reputational damage!
