For example, you can assign specific access levels like read-only or edit permissions. Additionally, companies can enforce security policies to mitigate the risk of unauthorized viewing or modification of sensitive information. 

Additional Security Measures

Some of the additional security measures that you can follow are secure document destruction, regular security audits, and two-factor authentication. These can significantly enhance the security of your PDF documents when shared online.

Secure Document Destruction

It will help you ensure that all the PDFs that are no longer needed are securely disposed of to prevent unauthorized access or retrieval. To destroy, you can shred physical copies or use specialized software to delete all digital files.

Frequent Security Audits

Secondly, doing regular security audits of PDF management tools and file-sharing processes can help you discover potential vulnerabilities and bugs. Conducting a thorough assessment regularly will help you identify and address any security issues that can lead to unauthorized access or data breaches. 

Implementing Two-Factor Authentication

Implementing two-factor authentication will help you add an extra security layer which will require users to validate two forms of identification before accessing any sensitive documents. It will help to prevent unauthorized access while enhancing the overall security of PDF documents. A few of the areas where you can implement 2FA are your work email account, social media accounts, etc.
