Says it will abide by UN guidelines to prevent abuses following scandals.
The Israeli-based NSO Group said on Tuesday it would abide by UN guidelines to prevent rights abuses, following accusations by cyber experts that its software was used in a number of government surveillance scandals.
Human rights group Amnesty International, which has asked Israel's government to revoke NSO's export licence, was sceptical that NSO's new policies would make a difference.
NSO is best known as a supplier of surveillance tools to governments and law enforcers, and says its products tackle and prevent serious crimes and support search and rescue operations after natural disasters.
But its cellphone hacking software, Pegasus, has been linked to political surveillance in Mexico, the United Arab Emirates and Saudi Arabia, according to University of Toronto's Citizen Lab, which researches digital surveillance, security, privacy and accountability.
Shalev Hulio, co-founder and chief executive of NSO, said: "NSO's products provide governments with the tools to help stop the world's worst terror attacks and most dangerous criminals. But (we) also understand that misuse could represent human rights violations."
NSO said it would from now on systematically apply UN procedures set in 2011 to identify risks that its technology could harm human rights, and then prevent or mitigate them.
It also plans to evaluate its sales process and contractually oblige customers to limit the use of its products to the prevention and investigation of serious crimes, and to ensure that they will not be used to violate human rights.
NSO needs to turn words into action, Danna Ingleton, deputy director of Amnesty Tech, the technology and human rights division of Amnesty, told Reuters.
"NSO is a company that has a history of saying one thing and doing another," she said. "The reason why they are doing this is to whitewash violations."
