Best Cloud Security Platform Reviews in 2026

Wiz scans cloud estates without agents and maps issues into attack paths, so teams see which combination of misconfiguration, vulnerability and exposed identity actually leads to a critical asset. That prioritisation is why many large teams moved to Wiz: it cuts alert noise by showing the path an attacker could take, not just a long list of findings. Coverage spans AWS, Azure, Google Cloud and Oracle Cloud, with code, container and AI workload modules added over time.

Google completed its acquisition of Wiz in March 2026, and Wiz states it remains a multicloud platform. Buyers who want a vendor neutral supplier should ask about roadmap parity across clouds during procurement. Pricing is quote based and scales with cloud resource count, so budget holders should expect an enterprise conversation, not a self serve checkout.

Orca Security uses agentless SideScanning to inspect cloud workloads from outside the workload itself, covering virtual machines, containers, Kubernetes, serverless and managed services. That approach gives fast coverage without installing agents on every host, which appeals to teams that need visibility quickly across many accounts. Orca remains independent, which matters for buyers in regulated sectors that prefer a vendor without a hyperscaler parent.

The trade off is maturity in detection and response compared with Wiz and Palo Alto at the largest scale. Orca pricing is bundled and quote based, simpler to understand than credit models but still enterprise priced at scale. For teams that value independent ownership and fast agentless onboarding, Orca is the most direct alternative to Wiz.

Cortex Cloud is the platform Palo Alto Networks formed by merging Prisma Cloud with Cortex CDR, announced in February 2025, with Prisma Cloud customers moving to Cortex Cloud. It covers code, posture, workload, container and runtime security in one platform, with deep Kubernetes admission control and enforcement. Teams already using Palo Alto firewalls or SOC tools gain a single vendor view across network and cloud.

Credit based pricing is the hardest part to plan. Credits map to protected resources, and the total depends on modules and scale, so a quote and a sizing exercise are essential. Agent based runtime coverage also adds more deployment work than a purely agentless start. For Palo Alto standardised enterprises, that breadth outweighs the complexity. For a team seeking the fastest agentless start, Wiz or Orca may fit better.

Microsoft Defender for Cloud is the native security platform for Azure, with a free Foundational CSPM tier and paid Defender plans for servers, containers, databases and other workloads. It is the only enterprise platform on this list with clearly published per resource pricing and a public cost calculator, plus a 30 day trial on paid plans. That transparency makes budgeting far easier than quote only rivals.

Multicloud coverage exists for AWS and Google Cloud, but the deepest integration, such as native Azure policy and remediation, sits on Azure. Teams that are mainly Azure based get strong value without adding a third party platform. Teams that are evenly split across clouds should compare multicloud posture depth with Wiz and Orca before deciding.

Sysdig focuses on runtime security for containers and Kubernetes, building on Falco open source detection. Its strength is showing which vulnerabilities are actually loaded and in use at runtime, so teams can ignore many findings that never execute. That filter matters for container teams drowning in scanner output.

Teams without a large container estate will get less value, since Sysdig is built around that workload type. Pricing is quote based and scales by hosts or workloads. For engineering led teams running Kubernetes at scale, Sysdig runtime depth is a strong reason to shortlist it beside a broader CNAPP.

CrowdStrike Falcon Cloud Security extends the Falcon platform into cloud workloads, containers and posture, with runtime detection and hunting that SOC teams already know from endpoint work. For firms already using CrowdStrike for endpoints, adding cloud security keeps detection, investigation and response in one console and one agent ecosystem where agents are used.

Pricing is per workload and module, quoted through sales, so totals rise as modules are added. Teams that do not use CrowdStrike elsewhere may find a dedicated CNAPP simpler to buy. For CrowdStrike estates that want SOC continuity across endpoint and cloud, it is a natural extension.

Tenable Cloud Security, built in part from the Ermetic acquisition, focuses on cloud identity and exposure: who can access what, which permissions are excessive, and which paths lead to sensitive data. Just in time access and permission analytics help teams cut standing privilege, a common cause of cloud breaches. Compliance mapping and posture checks sit beside that identity work.

Runtime detection is lighter than at Sysdig or CrowdStrike, so container heavy teams may need a second tool for deep runtime coverage. Pricing is quote based by resource. For security teams whose main cloud risk is identity sprawl and over privileged accounts, Tenable offers focused depth that broader platforms sometimes underplay.

Prowler is an open source cloud security tool with hundreds of checks mapped to frameworks such as CIS and NIST, covering AWS, Azure, Google Cloud and Kubernetes. It costs nothing to run, fits well in continuous integration pipelines, and gives small teams a credible posture baseline without an enterprise contract. A commercial SaaS version exists for teams that want managed dashboards.

Prowler is not a full CNAPP. It does not provide managed runtime protection, attack path graphing at Wiz depth, or a vendor run response service. Your team must triage findings and build remediation workflows itself. For a small team, a startup, or a team auditing a larger platform purchase, Prowler is an excellent free starting point.
