Gardaí have now seized drugs worth over €15.5 as part of a major international operation linked to a criminal communication platform.
The operation has so far seen 11 people arrested in Ireland.
Five men were detained in the Dublin and eastern region while six people were previously arrested as part of Garda activity directly related to the investigation.
The platform known as Ghost was used to facilitate a wide range of criminal activities including large-scale drug trafficking, money laundering, instances of extreme violence and other forms of serious and organised crime.
Gardaí say it had gained traction among criminal organisations due to its advanced security features.
"Users could purchase the solution without any personal information," the force says.
"The solution used three encryption standards and offered the option to send a message followed by a specific code that results in self-destruction of all messages on the target phone."
This approach allowed criminal networks to communicate securely and coordinate operations across borders.

The operation was launched along with nine other countries on Monday and has since resulted in a total of 51 arrests around the world.
More than 30 searches have been carried out across the country with over 300 Gardaí involved.
Laptops, SIM cards, Rolex watches, €350,000 in cash and a Range Rover were seized.
Officers also intercepted an articulated truck in the southeast of the country and recovered 100kgs of cocaine in a deep concealment.
Representatives from Europol, Australian Federal Police and the US Federal Bureau of Investigation were also in Ireland in support of the ongoing operation.
'Crime networks know no boundaries'
Speaking at Europol Headquarters, Assistant Commissioner Justin Kelly said such gangs don't respect borders.
"An Garda Síochána's involvement in this Europol Operational Task Force demonstrates Ireland's ongoing commitment and capacity to operate at an international level targeting transnational organised crime groups which cause so much harm and misery not just in Ireland but in countries across the world," he said.
"Transnational organised crime group networks know no boundaries and do not respect any international borders or rules of law.
"It takes a network to defeat a network and today's announcement is clear indication of the power of Law Enforcement networks in degrading and dismantling the activities of these criminal networks," he added.
Detective Chief Superintendent Seamus Boland says Ireland had the second-highest number of encrypted devices in use.
"In excess of 8.3% of all devices on this criminal network that have gone live were devices that were being used here in Ireland," he said.
"So we're talking about in the region of 100 devices in total".
Gardaí say investigations are ongoing.
