The week, which is supported by 100 private and public sector groups including HM Government, The Economist, Hewlett Packard, Unilever and Publicis Groupe, includes a programme of 40 events in London.
The agency's founder Yvonne Eskenzi told PRWeek she organised the event in order to "give something back for free" to the industry she worked with. She also felt there was "a really huge gap in the market" given the lack of publicity she believed European Cyber Security Awareness Month – held every October for several years – achieved.
She said that clients had previously asked how to get coverage during the month, but this had not happened due to that lack of traction, and so she decided to organise her own event.
The inaugural event in the week was a photocall held near the Tower of London that was attended by 100 people from the industry, with 10 journalists from trade press also present.
Eskenzi says she hoped to reach around 500 people during the week, and that it will raise the profile of both her own clients and other firms.
Eskenzi said: "Cyber attacks, like the one suffered by TalkTalk, are just going to increase in severity and frequency. TalkTalk is just the latest in a long line of companies who've been targeted and come up short. I firmly believe that the only way we're going to be able to prevent these incidents is to stop working in silos and come together to share expertise and experiences to make the internet a safe place to trade online."
