The banks are all offering online banking customers a free copy of Trusteer's Rapport security software and, says Mick Paisley, Santander's head of information security and business resilience, the rollout of the technology at his bank is one of the largest free offers of online banking security from a UK financial institution.
According to Paisley, his team are seeing the level of attacks by cybercriminals broadly increasing both in terms of volumes and sophistication.
"Taking precautions can have a disproportional protective effect, customers don't have to do much to significantly increase their levels of protection, and Trusteer is one of those things which provide a significant benefit with minimal effort", he said.
Over at Trusteer, the firm's CEO Mickey Boodaei said that the Rapport software is now available to more than 70 banks worldwide and covers more than 12 million customers.
"While most users have desktop protection of some sort, they still don't have good protection against online banking threats. These threats are highly targeted and highly sophisticated and fly under the radar of traditional desktop security solutions", he said.
"Trusteer is entirely focused on working with the banks to identify and eliminate these threats through an array of services", he added.
