The National Data Strategy identifies data as being the driving force behind the UK’s economy and government.

However, government departments and agencies are facing increased threats to their data as cyber-attacks and other online risks proliferate.

According to government figures, 39% of UK businesses have identified a cyber attack in 2022, and the threats faced by many government and public sector organisations are huge. Cyber attacks can halt the delivery of vital public services and as more organisations embed flexible working practices – meaning more officials work from less secure networks – the scope for attacks on government data is widening.

This is why many organisations are spending large sums on online tools or better training for staff to protect themselves. But despite the investment, damaging cyber-attacks are still happening and this webinar, in partnership with Rubrik, set out how government can focus on the key bottom line of protecting valuable data from attacks.

This webinar shared insights from government and public sector organisations on how they have faced – and survived – cyber-attacks, and their approaches for making sure that the vital national asset of data remains protected at all times.

Join this webinar to find out:

  • How to assess the security of your data and prepare for increasing threats.
  • The impact cyber-attacks can have if data is not protected.
  • How to ensure your department or agency can continue to provide their services in the face of increasing threats.
