The “Early Check-In” Threat: What a Real-World Security Lesson Teaches Us About Cloud Security and AI

1. What did I see? A real-world security lesson: A recent high-profile security incident highlighted a simple but powerful pattern: when someone gains access before the perimeter is fully in place, “day-of” controls can be bypassed. The lesson translates directly to cloud security and AI adoption—risk often enters during onboarding, configuration, and early access, long before anyone thinks to turn on the strictest controls.

2. Why it matters? In our world of cloud security and AI adoption, we may be making the exact same “early check-in” mistake.

• The Shadow AI Loophole: Are our staff already using unapproved AI tools such as browser extensions or free LLMs? If so, could data be shared with those tools before we have clear usage rules, controls, and monitoring in place?
• The Infrastructure Gap: We may have robust security at the final API or login, but what about the cloud environment itself? Recent research shows that 86% of organisations have installed third-party code packages with critical vulnerabilities—introducing risk early in the software supply chain.
• Fragmented Visibility: Do the tools we use provide a 360-degree panoramic view across cloud, identity, and workloads—or do they focus mainly on external attacks while missing risks from trusted identities (for example, a compromised non-human identity or a misconfigured AI agent)?

3. So what? Visibility is the antidote to blind spots. To reduce “early check-in” risk in the cloud, focus on the following measures:

• Adopt "Day Zero" Governance: Security cannot start when the AI model goes live. It must start during the procurement and "check-in" phase of every cloud service.
• Continuous Monitoring Over Checkpoints: Change happens continuously. Use AI-driven monitoring tools to detect unusual activity in your cloud environment 24/7—not just during “official” business hours.
• Close the “Ghost” Credential Loophole: Dormant, unused, or unrotated credentials can quietly accumulate and expand your attack surface. Inventory and remove what’s not needed, enforce least privilege, and rotate credentials routinely—especially for non-human identities—to protect high-value assets.
