The UK Government's Legacy IT Conundrum: A Looming Threat to National Security


The UK government is grappling with issues surrounding legacy IT systems and their impact on data protection. Despite implementing some of the 14 recommendations from its Information Security Review, key officials acknowledge significant challenges remain in addressing these risks. The need for greater transparency and a more concerted effort to adopt modern technologies and best practices in data protection cannot be overstated.

  • The UK government is struggling to address the issue of legacy IT systems and their impact on data protection.
  • The Science, Innovation and Technology Committee grilled senior ministers about progress made towards implementing technical means to prevent sensitive data leaks.
  • Challenges in replacing traditional methods with modern alternatives pose significant hurdles in addressing critical security concerns.
  • The government faces uncertainty regarding assessments of its systems' data security and whether relevant data can be shared publicly.
  • A recent assurance exercise showed a 90% compliance rate with data security standards across departments, but further consultation is required before making decisions.
  • There is an urgent need for transparency from the government about its progress towards meeting recommendations outlined by the Information Security Review.


  • The United Kingdom government has been facing intense scrutiny over its efforts to address the pressing issue of legacy IT systems and their impact on data protection. The latest development in this saga came when Parliament's Science, Innovation and Technology Committee (SI&T) grilled senior ministers about the progress made towards implementing technical means to prevent highly sensitive data leaks.

    In a hearing that shed light on the government's response to its Information Security Review, which recommended developing methods for cross-government information sharing without relying on email, key figures including Ian Murray, minister for digital government and data, and Aimee Smith, the government's chief data officer, provided insight into the challenges faced by the government in this area.

    According to Smith, the reality of legacy IT systems operating across various departments poses significant hurdles in implementing new technical solutions. She pointed out that emailing attachments may be the only viable means of transferring information between different systems where legacy technology is prevalent. This highlights the complexity and difficulty of replacing traditional methods with modern alternatives, particularly when it comes to addressing critical security concerns.

    The committee also sought clarification on assessments made of government systems regarding data security and whether relevant data could be shared publicly. Murray revealed that while he wouldn't object to sharing private percentages of legacy systems across government with the committee, further consultation was required before making a decision.

    Another key figure in the hearing, Vincent Devine, head of UK government security, provided assurance that an "assurance exercise" had been conducted in October 2025. The results showed a 90 percent compliance rate with data security standards across departments. However, there were reservations regarding how much data would be reported this year as part of future annual reviews.

    The emphasis on the challenges posed by legacy IT systems underscores the need for the government to consider new approaches that mitigate risks associated with outdated technology. This includes not only implementing technical solutions but also fostering a culture that encourages the adoption of best practices in data protection and information sharing.

    Furthermore, there is an urgent requirement for transparency from the government about its progress towards meeting recommendations outlined by the Information Security Review. As Dame Chi noted during previous calls, it is essential to have measurable metrics tracking departmental progress, which would serve as a crucial benchmark for assessing the effectiveness of measures taken to address these issues.

    In conclusion, the UK government's efforts to modernize its IT infrastructure and enhance data protection are facing significant hurdles due to legacy systems. To mitigate these risks effectively, the government must adopt a proactive approach that not only addresses technical challenges but also cultivates an environment conducive to innovation and improvement in data security practices.
