The survey, conducted by information security firm SafeNet, questioned respondents about their data encryption and security policies. It revealed 5%, or one in 20 UK organisations, have no security measures at all to protect the data crossing their networks.
This compared with a similar level of 6% in the same survey last year. However, the survey showed that the overall levels of network protection are falling, as 34% of organisations were found to encrypt between 1% and 25% of their data.
In comparison, 26% of organisations admitted such low security measures in 2006, showing an 8% increase in the number of companies not taking adequate steps to encrypt their data.
"The level of encryption required will obviously vary from organisation to organisation, but companies should be looking to encrypt as much network traffic as possible, if not all of it," said Gary Clark, vice-president at SafeNet.
