The Central Bank has issued a warning about investment firm Izard Quin Division Holdings Limited (Switzerland), which the authority said was offering investment services in the country without authorisation.
The bank said it is a crime for an investment firm to operate in Ireland without its authorisation and its customers would not be eligible for compensation if any issues arose.
The Central Bank maintains a list of warnings around unauthorised firms on its website.
It has also encouraged members of the public to contact them if they have any information regarding such companies.
