Vendor lock-in: Why digital dependencies are risky

Vendor lock-in is one of the biggest risks of modern digital platforms and can be costly for companies and public authorities. The technical term refers to a strong dependency on one provider or supplier and can lead to high long-term costs, especially for software. Before we look at the risks to the security and sovereignty of companies in this article and show the way out of this possible dependency, let's take a trip into the entertainment industry. The British science fiction series "Black Mirror", which is available on Netflix, provides an impressive dystopian example of the problem of vendor lock-in.

Vendor lock-in in serial form: existential dependence on one software

In the "Black Mirror" episode "Common People", the protagonist receives the devastating diagnosis of a brain tumor. Together with her husband, she discovers what at first glance appears to be a perfect solution: the fictional company "Rivermind" offers software that removes the damaged brain tissue and replaces it with neuro-structures from a cloud. The operation is free, but the service - i.e. the artificial maintenance of their consciousness - costs a monthly fee. The service works perfectly at the beginning. The relief is great. Amanda is alive. And together with her husband, she can more or less manage the subscription costs without any problems.

But little by little, the façade of the supposedly perfect cloud solution begins to crumble. The radius in which the protagonist can move freely becomes much smaller. Extreme fatigue complicates her everyday life. Then "Rivermind" places uncontrollable advertisements via Amanda that are aimed directly at her surroundings. The advertising can be circumvented with a more expensive "Plus" subscription, but this gets the couple into financial difficulties. The more expensive subscription is also quickly downgraded and the functions that enabled Amanda to lead a normal, dignified life without restrictions for a short time are now only included in the exorbitantly expensive "Lux" subscription. The standard subscription is no longer sufficient, and it is not possible to switch providers - after all, Amanda's consciousness is stored on the "Rivermind" cloud. Meanwhile, the subscription costs have become unaffordable for the desperate couple and inevitably lead to a grim end to the "Black Mirror" episode

Vendor lock-in in reality: the parallels to the dystopian series

 

Obviously, a cloud-based neuro-system that can take over all brain functions clearly belongs in the realm of science fiction. However, the parallels to the real risks that a vendor lock-in can pose for companies and institutions in the present day are impressive:

 

• Dependence on a single provider
  In the "Black Mirror" episode, the protagonist's life depends directly on the "Rivermind" service. Companies can also become dependent on software - with far-reaching financial consequences.
• Proprietary platform
  In the series world, Amanda's consciousness only runs on a single platform. "Rivermind" sets the rules and controls the entire technical and organizational ecosystem. In reality, companies face similar problems - for example, when a system can no longer be changed without incurring serious disadvantages.
• Price dictate
  From an inexpensive basic service to an unaffordable upgrade without which the usual functions are no longer available - in the series fiction, Amanda had to pay ever higher prices to be able to use basic services. Companies are familiar with this in the form of price increases that are only implemented after migration to the system, while higher fees are charged for essential features.

• Asymmetry
  The provider controls the infrastructure and defines the rules unilaterally. In this case, science fiction and reality are close to each other.

Vendor lock-in as a structural risk for companies

The definition of a "vendor lock-in" is based on the technical, economic or organizational dependency on a single provider, whereby a change is only possible with disproportionately high effort or not at all. A strong dependency is not synonymous with poor service, as such a lock-in often arises precisely because of convenient solutions. The lock-in becomes problematic when the dependency leads to long-term disadvantages in terms of the company's profitability, sovereignty and security, thus having a negative structural impact.

Vendor lock-in: risks for profitability

If the dependency on a single software becomes too great, the profitability of a company can be impaired. This can manifest itself in the form of license models or maintenance costs whose prices can no longer be negotiated. Costs for data migration, training or the adaptation of interfaces also become a risk. In the worst case scenario, this can lead to even inefficient solutions continuing to be operated for fear of the follow-up costs. The result: rising overall costs and less flexibility when making strategic decisions.

Vendor lock-in: risks for sovereignty

Software dependency significantly restricts the ability of companies and public authorities to make self-determined decisions about the further development of their own data. Those who rely on external providers with closed standards or proprietary technologies for central IT infrastructures and data run the risk of severely restricting their own scope for action. In this case, important decisions on interfaces, further developments or the location of data processing lie with the provider, which can lead to additional dependencies in terms of political framework conditions and economic interests, especially in the case of foreign service providers.

Vendor lock-in: risks for security

If only one provider has access to the system architecture, source code or security updates, a one-sided dependency can arise when it comes to identifying and rectifying vulnerabilities. Vendor lock-in in relation to security-relevant aspects of companies and authorities therefore refers to risks such as delayed patches, a lack of transparency or the end of product support. There is also the risk that security vulnerabilities are not communicated openly or are given lower priority from the vendor's perspective, which can significantly reduce the resilience of the entire IT landscape to failures or targeted attacks.

Avoid vendor lock-in - strengthen digital independence with open source

An effective counter to the typical risks of vendor lock-in is the use of open source platforms. Thanks to freely accessible source code, transparent development processes, open standards and modular architectures, control over systems and data remains with the user. The replacement of individual components is possible and does not lead to a complete reorganization of the IT infrastructure, while the open source approach also facilitates independent security checks and long-term maintainability. The economic, organizational and security-related risks of a vendor lock-in are thus significantly mitigated. In summary, the open source approach offers comprehensive advantages to counteract a potential vendor lock-in:

• Open source code promotes independence from individual software providers
• Reduced change and migration costs - individual components can be replaced with less effort
• Long-term planning without license or product constraints from a single provider
• Higher transparency for functionality and security-relevant aspects
• Strengthening of digital and economic sovereignty
