Integrate your own infrastructure: do not let security block the project

When the operating system must connect to internal servers or existing data, the security audit gate is where many projects get stuck unfairly.

Quick summary

If the operating system needs to access your private infrastructure, the integrator usually must undergo your organization's security assessment before being granted access. This includes signing a data processing agreement, answering a security questionnaire, and clearly defining who is responsible for which part of the infrastructure. Preparing from the scope phase helps avoid situations where the project is completed but fails security checks.

Integration projects into the client's private infrastructure often get stuck at the security audit stage, not due to technical or budget issues. The client's information security team will ask what certifications the partner has. They will also inquire about data protection processes and who is responsible in case of incidents. If not prepared in advance, the project can stall for weeks even if the technical part is complete.

When security issues become a prerequisite

Not every integration entails heavy auditing requirements. The extent depends on two core questions: what type of data is being affected, and where is that infrastructure located.

  • End customer data, personal information, medical records, or financial transactions: the strictest requirements, non-negotiable.
  • Internal operational data that does not contain personal information: requirements still exist but are usually more flexible.
  • Independent cloud tools, not connected to core systems: the lightest requirements, but still need to check the provider's terms.

The finance and healthcare sectors, as well as organizations that have implemented information security management systems, often have their own security teams. This team has specific criteria for evaluating external partners. You should consult that team as soon as you start discussing the project scope, not just when deployment is imminent.

Four things to prepare before integration

  • Data processing agreement: a document that specifies what each party can do with the data, where it is stored, when it can be deleted, and how incidents are reported. Not having this document when personal data is processed poses a direct legal risk.
  • Due diligence: your organization needs to assess the security capabilities and compliance status of the integrator before granting access. This is usually done through a security questionnaire, referencing SOC 2 reports (independent audit reports on service security controls) or ISO 27001 (international information security management standards). If certification is not available, both parties can acknowledge risks at an acceptable level.
  • Infrastructure responsibility boundaries: who is responsible for the server, who is responsible for the application, who gets called first when issues arise. If not clearly defined from the start, blame-shifting later wastes time and damages relationships.
  • Audit rights and incident reporting obligations: the contract needs to specify whether your organization has the right to request periodic audits. The contract should also clarify the timeframe within which the integrator must report incidents.
Deep integration into internal infrastructure: passing through all audit gates, signing all necessary documents, and clearly defining boundaries. This may take longer initially, but it reduces the risk of getting stuck midway and avoids unclear responsibilities in case of incidents.

Use independent cloud tools: Lighter on procedures, but still check the provider's security policies and confirm what data passes through. Not suitable when data needs to remain within the organization's controlled environment.

Common mistakes that cause projects to be stuck midway

  • To discuss confidentiality requirements in the implementation phase, at which point the client’s security team may block progress entirely.
  • Not signing a data processing agreement because you think it's a minor procedure, then facing legal issues when personal data is involved.
  • The infrastructure boundary is not recorded in the contract, only agreed upon verbally, leading to disputes over responsibility when there is a system error.
  • Considering the security audit as a task for the technical team, not including it in the scope discussion right from the project kick-off meeting.

Evaluate partners first, then grant access to the system. It's not about suspicion, but about protecting both parties.

When to self-handle and when to outsource

If the business already has a capable technical team to receive the system, self-managing sensitive infrastructure is often a reasonable choice as the data remains under control. If not, hiring a specialized party for infrastructure and security is usually safer than relying on someone who is multitasking. What should be avoided is leaving sensitive parts unassigned.

In tightly regulated sectors like finance or healthcare, it is advisable to assess internal capabilities before signing contracts, rather than discovering a lack of personnel to take over midway through the project.

Frequently asked questions

Does the integrator need SOC 2 or ISO 27001 certification?

It depends on your organization's requirements. Many information security teams ask for certifications such as SOC 2 or ISO 27001 when assessing partners. If the integrator does not have these, both parties can acknowledge risks at an acceptable level and clearly outline the boundaries of responsibility in writing. Sensitive infrastructure should belong to the party capable of operating it and proving that capability.

What is a data processing agreement and is it mandatory?

The data processing agreement is a document that specifies what each party can do with the data, where it is stored, when it can be deleted, and how incidents are reported. When personal data of end customers is processed, current regulations on personal data protection (Law No. 91/2025 and Decree No. 356/2025) impose obligations on the processor, making this document almost indispensable, especially in finance and healthcare. This is for reference; you should consult a lawyer for your specific case.

If you only use external cloud tools, is an audit necessary?

Independent cloud tools that do not connect to the core internal infrastructure usually have lighter requirements. However, if the tool processes end customer data or connects to existing systems, you still need to review the provider's privacy policy and service terms. The critical boundary is which data passes through that tool.
