How to Vet SaaS Integrations

Modern businesses run on a web of interconnected Software-as-a-Service (SaaS) tools. While these integrations boost productivity, each one acts as a bridge to your sensitive data. Without a rigorous vetting process, these bridges can become vulnerabilities. The 2023 T-Mobile breach demonstrated how a sprawling digital ecosystem multiplies the "attack surface". To protect your reputation and remain compliant with regulations like GDPR, you must treat every new integration with professional scrutiny.

5 Steps for Vetting SaaS Vendors

Millions of users rely on assistive aids or have varying degrees of visual impairment.

1. Scrutinise the Vendor’s Security Posture

A sleek interface is no substitute for a solid security foundation.

  • The Audit: Request a SOC 2 Type II report. This independent audit verifies the vendor’s controls over confidentiality, integrity, and privacy.
  • The Background: Investigate the company’s history, founders, and breach disclosure policies. Reputable vendors are transparent about how they handle vulnerabilities.

2. Map the Data Flow

You must understand exactly what data the integration will touch.

  • Permissions: Be wary of apps requesting global "read and write" access. Apply the principle of least privilege: grant only the minimum access required for the task.
  • Encryption: Verify that data is encrypted both "at rest" and "in transit". Ask for a diagram showing where data is stored and the geographical location of their servers.

3. Review Compliance and Legal Terms

If your business must comply with GDPR, your vendors must too.

  • Legal Roles: Confirm whether the vendor acts as a "data processor" or "data controller".
  • Data Sovereignty: Ensure they will sign a Data Processing Addendum (DPA) and that their data centres are not located in regions with lax privacy laws.

4. Require Secure Authentication

Avoid any service that asks for shared login credentials.

  • Protocols: Prioritise integrations using modern standards like OAuth 2.0, which allow systems to connect securely without sharing passwords.
  • Admin Controls: Ensure your IT team can grant or revoke access instantly via a central dashboard.

5. Plan for the Exit

Every software partnership eventually ends. Before signing up, ensure you can "offboard" cleanly.

  • Data Portability: Can you export your data in a standard format?
  • Deletion Guarantees: How does the vendor prove that your information has been permanently deleted from their servers once the contract ends?

Building a Resilient Stack
