APIs now sit at the center of almost every digital product, from mobile apps and SaaS platforms to embedded services. As organizations scale, the number of endpoints grows quickly, as does the attack surface. Unmonitored or misconfigured APIs have already led to major incidents across industries, including data exposure, broken authentication, and large-scale account takeover.

Cilium network policies (CNPs) extend Kubernetes’ L3/L4 controls to the application layer (L7). CNPs provide teams with advanced networking capabilities, but they can also introduce new ways for connectivity to fail, especially in environments running thousands of workloads. Many of these issues stem from differences in how Kubernetes and Cilium interpret the same concepts, such as label scoping, IP-based rules, service identities, and how default-deny behavior is applied.

In 2025, many of the long-standing cloud security concerns remained, but new areas of focus also developed. The significant increase in AI adoption enabled organizations to deliver features faster but also introduced new attack surfaces, such as untrusted or unpredictable user input for large language model (LLM) applications. At the same time, long-lived credentials and vulnerabilities in third-party packages continued to expose cloud environments to risk.

Defining success looks different for security organizations than it does for product, infrastructure, and other engineering teams. The latter group can often point to tangible outcomes, such as newly shipped features or performance improvements. Security orgs succeed when risks are lowered and the company’s posture improves over time, which are results that aren’t as easy to recognize but still valuable.

Security can quickly become overwhelming for large organizations, with teams processing logs that are fragmented across cloud providers and SaaS platforms, staggering alert volumes, and the need to scale operations efficiently as environments grow. Datadog Cloud SIEM is designed to help teams manage this workload by centralizing insights, detecting threats faster, and prioritizing investigations with rich risk context.

As development teams adopt generative AI at an unprecedented pace, security teams face an evolving set of challenges in securing the software development life cycle. The increasing speed and scale of code changes make it more difficult for organizations to manage risk effectively. Legacy scanners often fail to keep up, returning slow results and noisy alerts that increase remediation time and leave organizations exposed to potential breaches.

Securing secrets is a difficult task. Developers frequently hardcode credentials for quick testing or use AI-generated code snippets that include live API keys or tokens. This means that enterprise secrets can inadvertently make their way into repositories and pipelines, exposing organizations to security and compliance risks without anyone noticing. When a secret is committed to a repository, it spreads quickly across branches, becomes difficult to track, and leads to leaks that are hard to clean up.
