Security & defence

Security organizations, defence and their partners need fast answers from each other, while the underlying information is classified, medical or otherwise confidential. Linksight delivers the answer, such as a match or a signal, without the source handing over its data.

No-fly lists (blacklist check)

Screen passengers against watchlists without pooling passenger data.

No-fly screening checks passengers against security watchlists: government lists and the banned-passenger lists individual airlines keep. Identity data is spread across organizations that must match it accurately under GDPR and aviation security rules, and none of them may simply exchange passenger files. Screening gets safer and faster at once: fewer false positives, fewer manual reviews, shorter delays. Airlines and authorities can demonstrate GDPR compliance while trusting each other’s matches. Linksight matches identities across airlines and authorities; passenger data stays with each organization and is never shared in bulk. Strong governance and auditability back every match.

Weapons permit

The licensing authority gets an answer, not the medical file.

Weapons permits are issued by the police or another licensing authority, which must check whether an applicant poses a risk to themselves or others, for instance due to serious mental health problems. The information for that check sits with healthcare providers and other public bodies, and medical confidentiality, GDPR, and firearms law strictly limit what they may hand over. Permits stop being issued on incomplete information, and authorities decide faster and on evidence. Citizens keep the assurance that their medical records do not spread across government systems. Through Linksight, the authority receives only the answer the law entitles it to, such as whether a serious concern is on record; the records themselves stay where they are. Identity matching, governance, and audit logging make the check demonstrably compliant.

Threat intelligence (“have you seen this IP address?”)

Ask another organization “have you seen this IP address?” without revealing which address you mean.

Organizations facing the same attackers want to know whether an indicator, an IP address, a domain, a file hash, has been seen in each other’s environments. Asking outright betrays what you are investigating, and no security team hands over its telemetry. Shared threats surface earlier and responses can be coordinated, without anyone first handing over sensitive data. The barrier to collaborating drops: partners exchange exactly what is needed and nothing more. Linksight matches cyber indicators across organizations with secure record linkage: both sides learn only whether there is a match. Neither the queried value nor the underlying datasets are exposed.

Supply chain data sharing

A shared view of the defense supply chain, without opening anyone’s systems.

Defense organizations and their suppliers depend on each other’s information about assets, components, maintenance, and logistics. That data is distributed, classified at different levels, stored in incompatible formats, and none of it may leak. Both sides get a shared view of assets, stock, and maintenance needs. The result is less duplication, faster maintenance, and operational planning built on facts rather than assumptions. Linksight links records across ministries, vendors, and international partners without centralizing anything. Governance and access controls keep the collaboration confidentiality-preserving.

Cross-border airspace verification

Verify an unknown aircraft against allied data in moments, not meetings.

When an aircraft or drone appears, defense organizations must judge quickly: authorized, unknown, or threat? The information that answers it often sits with allied nations, behind strict security, sovereignty, and sharing restrictions. Threat assessment speeds up, and friendly or authorized aircraft are misidentified less often. Allies decide on the same picture of their shared airspace. Linksight matches aircraft and flight records across national defense systems without unrestricted data sharing; each nation’s data stays under its own control. Governance and access controls keep sovereignty intact.
