As SAP invests heavily in mobile, a security testing company will release a tool next month to ensure mobile-accessible SAP systems are not vulnerable to hackers. Boston-based Onapsis will release a new module for its X1 security suite, a product that performs automated security assessments, penetration testing and compliance audits for SAP’s ERP (enterprise resource planning) software, said Mariano Nunez, Onapsis’ CEO. The module will focus in part on the SAP Mobile Platform, formerly known as the Sybase Unwired Platform Developer Center, which helps developers build SAP mobile applications for different devices and platforms.
