Integration drives business. But a poorly implemented integration can also unintentionally move your sensitive data to places where it shouldn't be.
In 2025, the security of integrations ceased to be “a check” to become a architecture requirement: strong authentication, encryption in transit and at rest, least privilege access controls, continuous monitoring and data governance.
If one fails, the risk escalates: leaks, unavailability, fraud, fines and loss of trust.
Why integrations break down (and what consequences it brings)
When an integration fails in your security design, it usually happens because of at least one of these causes:
Weak authentication or exposed credentials
Reused/filtered passwords, tokens without rotation, absence of MFA. CISA explicitly recommends MFA, strong passwords and upgrades constants such as basic hygiene that significantly reduces risk; this basis applies to both individuals and organizations
Excessive permissions (“everything is admin”)
Wide access for convenience is the enemy of the principle of minimum privilege: increases the attack surface and the severity of a successful lateral movement. Las best practice guides they place it as a fundamental control.
Data “out in the open”
No encryption in transit or at rest, or with poorly managed keys. Best practices prioritize encryption at rest and encryption in transit with authenticated protocols.
Lack of segmentation and monitoring
Sin network segmentation And without traces/auditing, an incident becomes invisible for too long. Segmentation and recording/auditing are recommended controls in summaries of good practices and protocols.
Insecure or outdated processes
Late patching, reliance on outdated software, insufficient training... The result: ransomware, phishing and insider threats with operational and reputational impact.

Regulatory Compliance, GDPR and ISO 27001
No: “being in the cloud” is not enough. Compliance frameworks require verifiable controls:
- ISO/IEC 27001: international standard per information security management systems (ISMS). It defines controls over access, cryptography, physical security and incident management; certification involves regular audits and continuous improvement.
- GDPR (EU): requires the protection of personal data with appropriate technical and organizational measures. La figure is a key means of supporting compliance, along with access and minimization policies.
In short: government + technical controls. It's not about filling out forms, it's about prove that your integrations apply encryption, minimum privilege, segmentation, and risk-based monitoring.
Essential best practices for secure integrations
Inspired by CISA guides of the American government and compendiums of best practices techniques, this is a executive list to integrate seamlessly:
- Strong authentication and MFA in all integration jumps (APIs, connectors, bases). Update software and dependencies with priority.
- Minimum privilege and separation of duties (SoD). Design specific roles and scopes by integration and avoid shared credentials.
- End-to-end encryption:
- In transit: authenticated protocols (e.g., well-configured TLS).
- At rest: encryption of databases, files and message queues.
- Secure secret management: periodic rotation of API keys/tokens, avoid exposed “.env”, record usage and Automate revocation when the risk context changes. (Best Practices for Encryption and Access Governance).
- Network segmentation and minimum “blast radius” principle so that a gap doesn't involve the entire ecosystem. It complements with firewalls, checklists and microsegmentation.
- Security observability: auditing and traceability of integration events, misuse detection and alerts in the face of anomalies.
- Incident Response Plan (IR) tested: detection, containment, eradication and lessons learned; train the team and do drills.
Architecture type: Security fails in the limits (between systems). Design with faults in mind: short expiration times, idempotent retries, DLQ queues, validation and sanitization of data on each edge. Best practice guidelines highlight that “the real problem is often weak architecture”, not the absence of a single tool.
How does Weavee solve it in practice?
La Weavee Universal Connection is an iPaaS approach for centralize and orchestrate critical integrations between ERP, CRM, eCommerce, WMS and more, with a focus on security and scalability. Key points of the service:
- Architecture on Microsoft Azure: Azure's secure and scalable infrastructure supports global deployment and operational continuity.
- High-level compliance: ISO 27001, ISO 27018, SOC 1/2/3, FedRAMP, HITRUST, MTCS, IRAP and ENS.
- Supported authentication methods: (HTTP, API Key, Bearer Token, Basic Auth) and connectivity with cloud repositories (Google Drive, OneDrive) and databases (MS SQL Server).
- Centralized monitoring and control with real-time alerts and reports to ensure operational continuity and traceability.
Recommended deployment pattern with Weavee
- Inventory and mapping of sensitive data. Classify by sensitivity (e.g., public/internal/confidential/restricted) to assign differentiated controls by flow.
- Design of roles and scopes by integration. Avoid excessive permissions; each connector with its identity and clear boundaries.
- Encryption and secret management. Encryption in transit/at rest and rotation of credentials/tokens in accordance with policy.
- Segmentation and hardening of the components that end and originate the flows (gateways, data stores, queues).
- Observability and auditing: logs correlated by integration, misuse detection and anomaly alerts.
- IR Tests: runbooks, tabletop exercises and specific MTTR metrics for integrations.

From requirements to controls: quick mapping
- GDPR → data minimization, access control, adequate encryption and technical/organizational safeguards. Encryption and access policies support compliance.
- ISO/IEC 27001 → formal government (ISMS), cryptographic controls, access control, incident management and auditing. Your program should evidence these controls in integration flows.
Expected result: lower exposure, resilience to incidents and traceability to comply and demonstrate compliance.
Operational check-list (so as not to forget the essentials)
- MFA and unshared credential management.
- Minimum privilege per connector/flow.
- Encryption: Well configured TLS + encryption at rest.
- Network segmentation and edge controls.
- Audit/alerts and tested response plan
- Evidences for ISO 27001/GDPR in integrations.
How to Move Forward Today (Frictionless)
- Evaluate your current position with an inventory of integrations and a map of sensitive data; prioritizes security quick wins (key rotation, TLS, scopes).
- Centralize and standardize: an iPaaS reduces connections and provides consistent controls (access, encryption, monitoring) across the ecosystem. Weavee Universal Connection was designed for that and runs on Azure with stated security and compliance standards.
- Measure and improve: defines metrics (errors per 1,000 integrations, latency, secret rotation time, incident MTTR) and reviews monthly.

Integrate It's not moving data: is Move them with guarantees. With good practices applied at each edge (authentication, encryption, minimum privileges, segmentation, observability) and an iPaaS platform that standardizes these controls, your architecture gains resilience and your compliance becomes demonstrable.
