If the numbers do not get your attention, something should. Supply chain attacks rose 431 percent from 2021 to 2023. Experts expect nearly half of organizations to face at least one software supply chain incident by 2025. These are not small, quiet events. They hit operations, revenue, and trust.
What to act on right now:
APIs are commonly used to connect services, and they are easy to misconfigure. A public endpoint, an overbroad permission, or a leaked API key can give attackers a way in. Problems in vendor APIs often ripple through integrations and customer systems.
Unpatched vendor software and holes in build pipelines are another frequent cause. Attackers have altered installers and updates to carry malicious code. When the vendor update reaches you, the attack moves fast because the update looks legitimate.
Country of build and hosting choices matter more than before. Hosting in zones with weak protections, or depending on vendors in tense geopolitical regions, raises the chance of state-influenced or opportunistic attacks. For critical vendors, ask where their code is built and whether extra checks are in place for cross-border risk.
APIs, patched or not, also interact poorly with identity systems. A single compromised API key can let attackers impersonate services and move laterally. That is why monitoring calls to sensitive endpoints and tracking unusual volumes matters. Look for spikes at odd hours, strange payloads, or repeated failed authentications that suddenly succeed.
A food distribution firm recently had its core systems hit and experienced a multi-week disruption that affected grocery availability and sales. That incident showed how a single supplier problem can cause shops to scramble for alternatives and cost companies hundreds of millions in lost revenue.
A communication software vendor delivered an installer that had been tampered with in the build chain, pushing malware to customers. That case illustrated how trust in a signed package can be abused and why code signing and build checks matter.
Developer tools and CI servers have been targeted as well. Compromised build tools allow changes to flow into many downstream products quickly, so developer environments and CI logs need clear guardrails and monitoring.
When these incidents happen, the noise is overwhelming. Teams spend hours piecing together timelines, chasing indicators, and talking to vendors while customers wait. That delay multiplies damage. Fast, plain statements and a clear vendor plan make recovery smoother and limit the business impact.
Quarterly questionnaires and static reports make procurement feel better, but they miss change. A vendor can be fine on paper and still have a compromised pipeline the next day.
Attestations without telemetry are thin protection. Vendors can state compliance, but telemetry and live signals are what reveal abnormal behavior. Having access to read-only logs or receiving feeds from vendor systems gives you something real to act on.
Mapping vendor behavior to known attack techniques turns alerts into useful tasks. If an event maps to a known technique, your team can respond in a repeatable way rather than guessing.
Emerging tools can read vendor telemetry, flag strange behavior, and suggest clear next steps. These tools take noisy signals and present short, understandable findings to analysts. The aim is to reduce the hours spent sifting logs into a single actionable sentence.
Utilize these tools to continuously score vendor signals while maintaining human oversight. Let the system suggest containment steps and let analysts confirm before any blocking moves are made. That keeps false positives from breaking workflows and keeps trust high.

Link vendor checks to familiar standards so auditors and regulators see clear proof of control. Create a simple matrix that ties each vendor KRI to specific control IDs in ISO 27001, NIST guidance, and ATT&CK techniques you watch for.
For firms subject to EU rules, recent regulation requires faster reporting and clearer vendor criticality. Set thresholds that tie vendor failures to reporting timelines so your legal and operations teams can act without scrambling.
Use standards in procurement conversations. When buying, ask vendors where they sit against common controls and whether their telemetry can be shared in a safe way.
Each item above is practical and small, but together they stop many common breaches and cut the time it takes you to spot trouble.
If you can detect a vendor issue within 24 hours, keep core suppliers on near real-time watch, and block risky deployments when a score dips, you reduce the likelihood that one vendor becomes a board-level crisis. Track three measures: how many critical vendors send usable telemetry, median time to detect a vendor issue, and the percentage of critical suppliers that provide signed SBOMs.
Start small: choose one critical supplier, ask for their SBOM and a week of telemetry, then run an exercise. Early wins build confidence and force better vendor conversations. That practical step shows boards and regulators you are managing real risk, not just checking boxes. Start now.
Do not let vendor risk be the call you take at midnight. Reach out to iRM on their Contact Us page and request a focused vendor risk review that prioritizes streaming signals and short, practical playbooks. A single conversation with the right team can change what keeps you up at night.
