CHECK Point expects business of its mobile data protection to surge in China on demand from multinational companies, domestic banks, telecommunications and auditing firms, the US-based IT security service provider said yesterday.

Check Point's mobile data protection products help clients to keep the sensitive enterprise data from employees' USB disks, laptops, PDAs and mobile phones.

"People often lose the devices like cell phones and PDAs. Sometimes the information in the devices is much more valuable than the cost of the devices and loss of the data will damage companies," said Nelson Woo, Check Point's security consultant in North Asia.

In overseas markets, companies have to purchase mobile data protection licenses to comply with laws like the Sarbanes-Oxley Act in the United States but there are no such laws in China, according to Woo.
