UK Defence Innovation (UKDI) has relaunched the Security Open Call, inviting innovators to submit disruptive technologies that could strengthen the UK’s security, public safety and protective security capabilities.
What innovations are we looking for?
UKDI seeks disruptive technologies and innovative approaches that can help address some of the UK’s most pressing security challenges across public safety, national security, border security and protective security.
This cycle of the Security Open Call competition focuses on priorities identified by the
Home Office
and the
National Protective Security Authority
(NPSA), with future cycles potentially reflecting the priorities of different or additional government stakeholders.
Home Office Challenge Areas include secure data sharing across policing and government, tackling online harms and cyber-enabled threats, strengthening national security resilience, understanding migration behaviours, disrupting organised immigration crime, and improving border and immigration outcomes through innovation and technology.
NPSA Challenge Areas include vehicle screening, extended reality, crowd screening, hostile reconnaissance detection, AI-enabled training and intrusion detection technologies.

What Technology Readiness Level is expected?
Funded projects are expected to deliver a prototype or technology demonstrator at Technology Readiness Level 6 or 7 and show a realistic route to operational impact within two years of project completion.
The application process
The Security Open Call uses a two-stage application process designed to identify promising ideas at pace while reducing bidding effort for innovators.
Applicants will first submit a Stage 1 overview proposal, which UKDI will share with the competition challenge owners. Ideas that align well with the Competition Focus Areas, demonstrate a strong chance of successful delivery and meet the customer’s needs will be invited to progress to a full Stage 2 submission.
Proposals will only be funded where there is alignment to the competition challenges and strong demand for the idea.
UKDI’s
Innovation Partners
are available to support innovators throughout the application process.
How much funding is available?
Successful proposals for the Security Open Call can be funded up to £350,000. Projects can run for a maximum of 12 months, with an optional testing and trialling phase costed into proposals to extend activity to 18 months.
Key dates:
The first cycle opens on 3 August 2026 and closes on 27 August 2026, with additional cycles planned throughout 2026 and 2027.
