Garda Commissioner Drew Harris has said a special case review will be carried out into the actions of Paul Moody.
The former garda was jailed for over three years last week after pleading guilty to a charge of coercive control of a woman ill with cancer.
Nineteen other charges, including assault, theft, criminal damage and a threat to kill the woman known as 'Nicola', were taken into account.
Commissioner Harris said the force wanted to learn lessons from the case and said he hopes the review will be completed in a matter of weeks.
He said all the circumstances and matters that came up in court will be examined as part of the review.
The Dublin Circuit Criminal Court heard Moody used his position to terrify the woman's family and isolate her from everyone she knew.
His trial heard 'Nicola’ rang the garda station he was attached to in order to speak to "his boss", but Moody manipulated a colleague to "redirect the call" to him.
Commissioner Harris said if any wrongdoing by any other members of An Garda Síochána was identified, it would be dealt with in conjunction with the Garda Ombudsman.
He said the review was ordered to "turn over every stone, but we want to learn lessons as well around identifying individuals who are a risk to members of the public and who then use their position within An Garda Síochána for a malign purpose".
Commissioner Harris said he asked for the review last week and assurances have been given to the Policing Authority and the Minister for Justice that this review is under way.
Speaking for the first time since the former Garda was sentenced, Commissioner Harris described the investigation as very thorough and very professional.
He said justice has been served but and that the wheels of the criminal justice system acted appropriately in this case.
Commissioner Harris said due to the "nature of those lessons in the report, it will first be reported to the Minister and the Policing Authority".
Commissioner Harris said if any wrongdoing by any other members of An Garda Síochána was identified, it would be dealt with in conjunction with the Garda Ombudsman.
He said members of the public should always come forward if they have a complaint to make about members of the force, that if they feel uneasy or lack confidence there are a number of ways to come forward.
"Whatever route you choose, do make a complaint. Go to GSOC, through your solicitor, come to ourselves - but do make that complaint. Do not delay," he said.
