The safety and security of the Defence estate continues to be a priority key for Defence and we are taking decisive action to strengthen security across our estate, reversing years of under-investment and focusing our resources on our highest priority sites.

The Department is using in-year funding to deliver physical security enhancements, focussing on high priority sites across the defence estate. We have delivered urgent physical enhancements, introduced advanced surveillance technology such as the Immediate Threat Mitigation Solution, and we are investing £20 million in digital transformation to modernise our approach. Enhanced vigilance, updated guidance, and improved reporting have made it easier for personnel and industry partners to report incidents, while successful recruitment campaigns are increasing our policing and guard capacity.

The Strategic Defence Review recognised that we are in a new era of threat, which demands a new era for UK Defence.

We remain committed to maintaining the highest standards of security to safeguard our national defence capabilities.
