Barclays Bank has raised its employees' awareness of information security by a factor of 10, after turning to Hollywood to educate over 100,000 staff.
The bank produced a "mockumentary" made up of short Hollywood blockbuster-style films to illustrate key information security principles.
"Access Denied" Barclays' video on incident reporting:
"We wanted to do something different and be clever about delivery," said Mark Logsdon, deputy head of information risk management at Barclays.
Breaking from the standard corporate format was more successful than expected, he told information security professionals at an ISC2 Secure London conference.
"The proposal was certainly different and not like anything I had seen in Barclays. It was risky, but we managed this by involving all stakeholders in the process," he said.
Barclays recruited representatives of the legal, compliance, audit, marketing and communications departments to support the project.
"The video was not mandatory, but we had unexpected demand across the business, driven by movie posters, film trailers and a film premier event," said Logsdon.
Barclays made the video available to its 140,000 employees around the world, recording a tenfold increase in the reporting of security risks and incidents.
"Many more employees now know exactly what to do if they encounter any security risks or incidents," said Logsdon.
The video has not only been effective in communicating information security principles, but has also proven to be cost-effective, he said.
"Many organisations are put off by the cost, but the whole project has worked out at less than £1 per employee," said Logsdon.
The project took only four months to complete from concept to release, but should last up to five years as the film can be edited and updated, he said.
Barclays worked with a Leicester-based production company to make the film.
