Understanding the Risks: AI Integration and Cloud Security
In 2025, the enterprise risk landscape experienced a paradigm shift: the adoption of AI and LLMs officially becoming the primary driver of cloud risk. Today, almost 88% of organizations now leverage AI in at least one business function. With this level of integration, the risk of AI is now outpacing traditional security guardrails, culminating in a highly complex and interconnected attack surface. SentinelOne’s new AI and Cloud Verified Exploit Paths and Secrets Scanning Report examines this evolving threatscape and draws on telemetry from over 11,000 anonymized customer environments to offer deeper visibility into how threat actors are actively exploiting modern cloud and AI infrastructures. A primary finding of the 2026 report is the rising proliferation of AI-specific credentials. The data indicates that AI-related secrets — such as OpenAI API Keys, Azure OpenAI API Keys, and others — increased by approximately 140% in a span of one year. This growth correlates directly with the rapid embedding of AI technologies into customer support systems, internal tooling, financial platforms, and product experiences. Ubiquitous deployment has generated a widespread organizational pattern known as 'shadow AI' – the unsanctioned use of AI tools in an environment without formal IT approval or security oversight. In practice, this occurs when developers or internal teams utilize unmanaged or personal LLM keys to process corporate data outside of sanctioned IT or security channels. Since these AI integrations span numerous internal applications, the same API keys are frequently duplicated and stored within code repositories, SaaS configurations, and development scripts. Compounding this, these credentials are often implemented without proper access controls or routine rotation schedules. The sprawl of these credentials renders them difficult to track via standard secrets management protocols, establishing a requirement for more centralized governance over how AI keys are issued and utilized.
