Technology Concentration Risk: Why Businesses Need a Software Exit Plan

The businesses rely on third party software for their critical operations including transaction processing, customer management and financial services. But what if a vendor ceases to exist, discontinues its software or changes the terms of business?

Besides loss of access to the service the businesses will face a challenge of replacing the software or deploying it independently.

This is called technology concentration risk – the exposure generated by reliance on a particular technology provider or system which lacks an alternative.

The software exit plan will help the businesses to be prepared for this situation in advance rather than face a disruption unexpectedly.

What Is Technology Concentration Risk?

Technology concentration risk appears when the organization becomes too dependent on a technology provider, platform or software system making the continuation of its operations difficult in case of any dependency failure.

It could be manifested in the following ways:

• Vendor concentration: the critical business operations depend on one software provider.
• Technical lock-in: proprietary architecture, integration or tools makes the switch difficult.
• Dependency concentration: multiple applications depend on one technology platform or software component.
• Knowledge concentration: only the vendor has knowledge of maintaining, rebuilding and deploying the software.

A certain amount of dependence is not necessarily undesirable. In some cases, integrated platforms can help to increase efficiency, to simplify complexity and accelerate development. However, as is mentioned in the UK Government's technical lock-in guidance, organizations should consider the cost of change and the effort required to switch vendors.

The real problem is not dependence. The real problem is dependence without a viable exit or recovery plan.

Why Technology Concentration Risk Is Important

1. A vendor failure can put critical operations at risk

A vendor insolvency or any kind of withdrawal from cooperation can deprive businesses of software that is critical for their operations.

Even if the source code is available, the organization may lack necessary dependencies, configurations or knowledge to run the application independently.

2. Switching providers can be expensive

The replacement of critical software is not as easy as buying another application. The process of migrating data, integrating systems, training employees and recreating an application can make switching providers costly and time-consuming.

As a result, businesses can find themselves dependent on a vendor despite the fact that it is no longer appropriate.

3. Acquisitions and product discontinuation introduce uncertainty

A vendor acquisition may affect pricing, licensing, product availability and support. Product discontinuation is also capable of causing similar issues.

The lack of a prior transition plan can limit the time available for the company to assess available alternatives and secure its operations.

4. Several systems can have common vulnerability

An enterprise may employ several applications, but all of them still rely on a single technology provider or software component.

In case the dependency fails, it may cause disruptions to several business operations. Therefore, enterprises need to know not only what vendors they use but also how their crucial systems depend on each other.

Why Do Enterprises Need a Software Exit Plan?

The software exit plan describes the way the business will maintain essential processes if it faces a situation of leaving the vendor or retrieving the software independently of the vendor.

The plan needs to be worked out before any critical situation arises, preferably during the establishment of the software relationship, and updated as the application evolves.

An effective exit plan answers five questions:

• Which of your business functions relies on the software?
• What will happen if your vendor is no longer available?
• Do you have a right to access all required software materials?
• Can the application be rebuilt and deployed independently?
• How are you going to operate while transitioning to an alternative?

For financial institutions, exit planning is also a matter of governance. Various frameworks like the European DORA outline the requirements for relevant ICT third-party arrangements. The applicability of which depends on the organization, services provided and regulation.

What Should a Software Exit Plan Include?

An effective software exit plan requires more than a termination clause. You have to consider the technical and operational actions required to ensure the continuity of operations.

1. Mapping of critical software dependencies

You must identify applications, infrastructures, integrations and third-party components used in the operation of your critical business functions. Systems that would have significant operational impacts in case of disruptions are prioritized.

2. Access rights to the software and the data

Make sure to establish contractual rights for accessing the appropriate source code, data, documentation and other recovery materials. Verify that the necessary materials are current and available according to the agreed exit conditions.

3. Document the recovery process

Document the build environment, the software dependencies and the configuration needs. It will help reducing the dependence on knowledge which is possessed by the original vendor only.

4. Determine a realistic exit route

Define whether your business will move to another vendor, take control over the application in-house or recover the existing software on an interim basis.

Estimate the time, costs, resources and expertise necessary for each exit path.

5. Test your plan in advance

Having a documented procedure does not prove that it will be working. Businesses should test recovery and transition procedures in advance, note failures and correct deficiencies before any disruption happens.

Software Escrow Is Different from Software Recoverability

Traditional software escrow helps secure the availability of source code and other deposited materials if certain release conditions are met. But simply getting access to those materials does not necessarily mean the application can be independently rebuilt and deployed.

Dependencies might be missing; build instructions may be inadequate or the software may only work within the vendor's environment.

This is the key difference:

Software escrow provides a framework for accessing deposited materials on the basis of agreed-upon terms.

Software recoverability verifies whether the software can actually be rebuilt, deployed and run independently.

Both the contractual entitlement to recover software and the ability to do so must be considered by businesses.

How Castler Assists Businesses in Preparing for Vendor Dependency Risk

Castler's Software Recoverability Platform helps bridge the gap between the availability of software materials and the verification of software recoverability.

The process consists of independently rebuilding and deploying the vendor software in a clean environment, reproducing the declared architecture and issuing a signed Proof of Recovery of the verified release.

It includes the following steps:

• Dependency mapping: Determining the necessary software components and build requirements.
• Independent rebuilding: Attempting to compile the application using the deposited materials in the absence of the vendor.
• Deployment validation: Deployment of the rebuilt application and its verification in accordance with the announced environment.
• Signed proof of recovery: Providing evidence reviewed by a named engineer, supported by build and deployment evidence.

This allows businesses to assess the gaps proactively and maintain a proof of recovery readiness despite software changes.

Castler does not solve all kinds of technology concentration risk problems or serve as an independent software vendor exit and migration plan. However, it solves one of the major components of such a plan, the establishment of whether crucial software can be rebuilt independently.

Conclusion

Technology concentration risk cannot always be avoided, but businesses can prepare for its consequences. A credible software exit plan combines contractual rights, documented dependencies and tested recovery procedures.

The important question is not just whether you can access your software when a vendor fails. It is whether you can actually get it running.
