Why Trust in Palantir Is Becoming a Cybersecurity Problem

Palantir has built a powerful business around one of the most valuable resources in the modern economy: data. Its software helps governments, militaries, police forces and companies connect information from different systems, identify patterns and make decisions. The technology can be useful in situations where organisations have too much information and too little time.
But Palantir’s growing influence is also producing a different kind of problem: 

People are increasingly asking whether software designed to improve security can itself become a threat to privacy, accountability and public trust.

The concern is not that Palantir is a conventional cybersecurity company selling antivirus software. Its core business is data integration and analytics. Its platforms are designed to help institutions combine information, analyse relationships and coordinate action. That makes the company strategically important but also politically controversial.

Palantir was founded in 2003 by Peter Thiel, Alex Karp and others, with early backing connected to the CIA’s venture-capital arm, In-Q-Tel. The company later became deeply involved in US defence and intelligence work, including the military’s Project Maven, which uses artificial intelligence to analyse surveillance data.

The company’s supporters describe this as a practical application of software to difficult national-security problems. Critics describe it as part of a wider movement sometimes called technomilitarism, the growing influence of technology companies in military, policing and state power. That debate has become more intense as Palantir expands beyond defence into immigration enforcement, healthcare and public-sector data systems.

One of the most controversial examples is its work with US Immigration and Customs Enforcement, or ICE. Investigations and reporting have linked Palantir’s technology to systems used to organise immigration information and support enforcement operations. The company’s role has made it a target of protests from civil-liberties groups and technology workers who argue that data analytics can make large-scale immigration enforcement more efficient without necessarily making it more accountable. The concern is not simply that software can identify a person. Modern data platforms can connect information that was previously stored in separate places: employment records, addresses, travel information, government databases, social-media activity and other digital traces.

When those datasets are combined, the resulting picture can become much more detailed than any individual record. That creates a difficult question for governments and technology companies: 

Does a person’s permission to provide information for one purpose automatically mean that the information can be combined and analysed for another purpose?

The answer is not always clear. Palantir says its platforms are controlled by the organisations that deploy them. The company argues that customers determine what data is collected, who can access it and how it is used. But critics respond that technical control by a customer does not eliminate the risks created by the system itself. A platform can be legally configured and still be used in ways that citizens find intrusive, discriminatory or disproportionate.

The controversy has also spread into healthcare. In 2023, NHS England awarded a consortium led by Palantir a £330 million contract to develop the NHS Federated Data Platform. The system is intended to connect operational information across the health service, including data related to waiting lists, staffing, patient care and hospital capacity. NHS England says the platform is designed to remain under NHS control and that suppliers must meet strict security and procurement requirements. The potential benefit is obvious. Britain’s National Health Service has historically struggled with fragmented information systems. A platform that helps hospitals understand capacity, coordinate treatment and reduce administrative delays could improve efficiency. But the contract has faced sustained criticism over privacy, procurement, performance and dependence on one supplier. A UK parliamentary debate raised concerns that the NHS would pay for a subscription service without owning the underlying software or intellectual property after the contract ends. Critics described this as a form of permanent vendor lock-in.

The British Medical Journal has also reported questions about the reliability of data used to promote a Palantir NHS pilot, including concerns about whether claimed benefits were independently validated. This is where cybersecurity and data governance overlap. A system can be technically secure but still create a governance problem if an institution becomes too dependent on one vendor. If the software is difficult to replace, if data cannot easily be migrated, or if the organisation cannot independently verify the system’s results, its control over critical infrastructure may weaken. The issue is especially serious when the data involves health records, immigration information, policing or national defence.

Palantir’s growing role in Britain has therefore prompted questions about whether governments are outsourcing too much strategic capability to private technology companies. The UK Parliament’s Science, Innovation and Technology Committee warned about the risks of excessive dependence on Palantir and other large technology suppliers, particularly where public services could be exposed to a single point of failure. 

Palantir has also faced criticism over its work with the Israeli military. Human-rights groups and critics argue that data-driven military systems can contribute to targeting decisions in Gaza and other conflict zones. Palantir has defended its defence work and has said that its technology supports allied governments and national-security missions. However, the debate has intensified because the company’s software sits close to decisions involving surveillance, military operations and the use of force.  The company’s expansion into Africa adds another layer to the discussion. Palantir has invested in Terra Industries, a Nigerian defence-technology startup founded by Nathan Nwachuku and Maxwell Maduka. Terra develops autonomous defence systems for governments and infrastructure operators, including drones and other systems designed for land, air and maritime applications. Terra announced an additional $18 million financing round in 2026, bringing its reported seed valuation to $52 million. The investment could help a Nigerian company develop advanced engineering capabilities, create technical jobs and build products for African security challenges. It could also strengthen Nigeria’s position in the global defence-technology ecosystem. But it is understandable that some observers will ask why an American defence-data company is investing in an African startup. Is Palantir seeking access to local information? Is it interested in African defence markets? Is it trying to expand its software ecosystem? Or is the investment primarily financial and strategic? At present, there is no verified public evidence that Palantir invested in Terra Industries specifically to obtain Nigerians’ personal data or feed information into a secret database. That claim should not be presented as fact. The more legitimate question is whether African governments and startups have sufficiently strong rules governing data ownership, data access, export controls, cybersecurity and the use of defence-related technology.

For African countries, this is not an argument against foreign investment. It is an argument for clearer boundaries. Any partnership involving sensitive data or defence technology should establish who owns the data, where it is stored, who can access it, whether it can be transferred outside the country, how long it is retained and what happens when the contract ends. These questions matter because public trust is becoming a competitive advantage in technology.

Palantir’s experience shows that technical capability alone is not enough. A platform may help police solve crimes faster, assist hospitals with operational planning or support military logistics, but citizens still need confidence that the system is being used lawfully and proportionately.

The same issue applies to political campaigns and election analytics. Political organisations increasingly use data to understand voter concerns, segment audiences and decide where to spend campaign resources. Social-media posts and public comments can provide useful information about public opinion, but the existence of publicly visible data does not automatically resolve questions about consent, profiling or manipulation. A person may publish a political opinion online without expecting that it will be combined with other information to produce a behavioural profile used by a political organisation. The challenge is therefore not only whether data is technically accessible. It is whether the use is transparent, expected and fair.

Palantir’s critics are right to ask difficult questions. But criticism should also be evidence-based. It is not accurate to assume that every Palantir deployment involves unrestricted access to personal data, nor is it accurate to assume that every deployment is harmless because the company says customers control the system. The truth depends on the contract, the data architecture, the access controls, the audit process and the institution using the software.That is the central lesson for Africa’s growing AI and cybersecurity economy. 

Governments should not evaluate data platforms only by asking what they can do. They should also ask what they could do if misused, who can stop that misuse, whether citizens can challenge decisions and whether the country can replace the supplier. Technology that connects fragmented information can create enormous public value. It can also concentrate power. The future of secure digital infrastructure will therefore depend on more than encryption and access controls. It will depend on transparency, independent audits, strong procurement rules, local technical capacity and the ability to say no when a system becomes too powerful or too difficult to replace.

Palantir’s story is a warning that the most important cybersecurity question is not always, Can someone hack the system?

Sometimes it is: Who controls the system, what can it reveal, and what happens when the public stops trusting it?
