PdfAl Protect PDF delivers consistent, device-agnostic protection with traceable processing history. Your documents are secured on desktops, tablets, or smartphones, with real-time status monitoring and activity logs for anytime, anywhere access.
Protect PDF from Editing and Copying with Audit-Enabled Passwords
Secure audit-trail-enabled protection for sensitive files such as financial statements, legal documents, or confidential reports. Apply passwords to block copying, editing, or printing, while maintaining an audit trail of access controls and password validation as part of the monitoring process. PdfAl also suggests strong passwords and enforces password validation for maximum safety.
How to set a strong password
Audit-conscious password guidance: avoid simple passwords. Strengthen security by using a minimum of 8 characters, including uppercase letters, numbers, and special symbols, with validation logs capturing password strength checks as part of compliance monitoring. The stronger the password, the greater the protection and traceability of your document.
