The numerous messages to users about increasing the protection around sensitive data appear to have fallen on deaf ears.
According to the Check Point annual UK data security survey the numbers of companies confessing ignorance about encryption are worryingly high.
Over the past 14 months there has been just a 1% increase in the number of companies deploying encryption.
This comes despite the continued high profile cases of government departments losing laptops, memory sticks and discs containing sensitive personal information.
“Evidently the lessons of the last year and a half – that a data loss or breach can happen to any organisation, whether private or public – have not been learned,” said Nick Lowe, Check Point’s regional director for Northern Europe.
“It’s amazing that there has been no significant growth in the use of data encryption, when it is the one security technology that can stop any type of data leak,” he added.
Of those companies surveyed by the vendor 38% said they did not have any encryption and 13% didn’t appear to have a clue admitting they didn’t know.
“Even though these incidents have been front-page news, over half the companies surveyed are still running the risk of innocent data loss, or malicious theft,” added Lowe.
