Modern businesses run on SaaS. From CRMs to project management tools, our data lives in a mesh of interconnected services. Attackers have realized that the easiest way into a hardened enterprise is through a trusted third-party integration.
The "Upstream" Attack
In a software supply chain attack, adversaries compromise a vendor, a plugin, or an open-source library that you rely on. Because you trust this source, the malicious code bypasses your perimeter defenses.
CI/CD Pipeline Threats
How One Leak Becomes a Production Breach
Your CI/CD pipeline (GitHub Actions, Jenkins, GitLab) has the "keys to the kingdom"—deploying code straight to production.
- Secret Sprawl: Hardcoded API keys in commit history.
- Poisoned Pipeline Execution (PPE): Attackers modifying build scripts to inject malware into the build artifact.
- Shadow Pipelines: Developers spinning up unauthorized workflows that lack security checks.
7 Questions That Catch Real Problems
Stop sending generic 100-page questionnaires. Ask your vendors these 7 questions to assess real risk:
- Do you use MFA for all administrative access?
- How do you isolate tenant data (our data) from others?
- Do you undergo annual independent penetration testing (and can we see the summary)?
- How do you manage secrets and encryption keys?
- What is your SLA for patching critical vulnerabilities?
- Do you have a Vulnerability Disclosure Program (VDP)?
- Do you scan your own software dependencies (SCA)?
