It is claimed our high speed internet connections to the UK are being monitored.
Documents released by whistleblower Edward Snowden show that our main underwater links - which in effect connect us to the rest of the world - have been targeted by British intelligence.
The Irish Times reports that the revelations are contained in documents leaked by National Security Agency (NSA) whistleblower Mr Snowden to a German media organisation.
A document called "Partner Cables" list the cables that the British government communications headquarters (GCHQ) has accessed or sought to access. The commercial owners of the cables are identified by codenames.
They include one undersea cable, which extends from the Wexford coast to southern Wales.
The Irish Times says British intelligence also has access to a cable which connects Ireland to the US and Canada from Dublin to Halifax, Nova Scotia.
It loops to the UK through Southport on the other side of the Irish Sea.
Transparency International says it raises questions about why this is happening and what is being done with the data.
Chief executive John Devitt says we need an explanation.
