Some 1,200 members of The Police Service of Northern Ireland have now been referred to a new emergency threat assessment group.
The group was set up to provide security advice after two data breaches revealed the identities of officers and staff.
It is providing immediate support to people with specific circumstances which may place them or their families at risk or at an increased threat of harm.
The development comes after the Chief Constable of the PSNI met representatives from all staff associations, including the Catholic Guild, which represents a significant number of Catholic members of the PSNI.
A statement from the PSNI said that Chief Constable Simon Byrne listened to the issues or concerns and reiterated his priority to the welfare and safety of all officers and staff.
He also reassured the Guild that he was committed to supporting everyone affected by the recent data breach.
