Already running CrowdStrike, SentinelOne or Microsoft Defender? What they offer for cloud

Why does an existing agent matter?

Deploying and maintaining an agent across a server fleet is real work. If an agent from a security vendor already runs there, adding cloud capabilities from the same vendor can avoid a second agent, a second console and a second contract. The finder gives three extra points to a vendor that extends a product you already run, more than any single other check, because that saving is real.

CrowdStrike Falcon Cloud Security

CrowdStrike says Falcon Cloud Security "unifies agentless visibility with the CrowdStrike Falcon sensor". It lists agentless CSPM, cloud workload protection with agent and agentless options, CIEM, ASPM and AI-SPM, and posture findings enriched with adversary intelligence. In March 2026 it announced a Cloud Risk Engine that maps cloud risks to adversary tradecraft. On the Falcon Cloud Security page re-read on 11 October 2026, DSPM and AI-driven vulnerability management are also named. Its public price is an AWS Marketplace pay-as-you-go listing combined with Next-Gen SIEM; CrowdStrike's own pricing page lists endpoint bundles only. Profile.

SentinelOne Singularity Cloud

SentinelOne describes Cloud Native Security as "an agentless CNAPP" and adds Cloud Workload Security for runtime protection of containers, VMs and AI workloads, sharing "one data model" with the wider Singularity platform. Its Offensive Security Engine checks which exposures are exploitable. Its product page names AWS, Azure and GCP among the clouds it onboards; a vulnerability management module is not named. Profile.

Microsoft Defender for Cloud

Defender for Servers Plan 1 and Plan 2 bring Microsoft Defender for Endpoint EDR to servers on Azure, AWS, Google Cloud and on-premises through Azure Arc. Posture comes from Foundational CSPM (free) and Defender CSPM (paid, per resource). Microsoft Learn describes native CIEM covering Microsoft Entra ID, AWS IAM and Google Cloud IAM. Profile.

What does an endpoint agent not cover?

An agent on a server sees that server. It does not see storage buckets, managed databases, serverless functions, identity policies or the configuration of the account around the server. Those come from API-based posture, identity and data checks. Each of the three sells those too, but they are separate from the agent, and their depth differs by category, as the category maps show.

What about containers?

Endpoint agents began on laptops and servers. For Kubernetes, ask how the agent is deployed per node, what it costs in resources, and whether it blocks or only detects. CrowdStrike and SentinelOne describe container runtime protection on the pages we read; Microsoft lists agentless Kubernetes discovery in its paid posture plan.

When should you look elsewhere?

When the categories you need most are not described by your endpoint vendor, when you cannot put its agent on the workloads that matter, or when you need clouds it does not name. Run the finder with your existing product selected: it adds the ecosystem points and still checks every other constraint.
