Human error is behind a bug that reportedly exposed thousands of Palo Alto Networks customer support tickets to an unauthorized individual. Exposed information included the names and business contact information of the person creating support tickets. It also included conversations between Palo Alto Networks staff members and the customer.

Mohit Tiwari is co-founder and CEO of cloud security provider Symmetry Systems. He made waves this week for putting the leak into perspective.

“Palo Alto Networks’ problem is not unique,” Tiwari said. “Most web applications have tens of millions of lines of code, most of it from the framework and libraries used to build the application. Making such a large application bug free is impossible.”
