ZEST Security is a cloud exposure management and remediation platform for security and DevOps teams. It brings together findings from cloud, application, vulnerability-management, SCA and ASPM tools, then applies AI agents to analyze root causes, prioritize risk and model remediation or mitigation pathways. Its scope spans cloud, code, containers, infrastructure as code, applications and software supply-chain risks, making it a fit for teams coordinating exposure reduction across multiple technical layers.

Its standout capability is contextual risk analysis. ZEST evaluates reachability, exploitability and business criticality, while tracing findings to assets, code, IaC and owners. Security teams can use agentless cloud exposure identification, cloud guardrail and policy analysis, remediation validation and workflow updates. Security as Code analysis and replacement-code generation extend the platform beyond detection, while simulation helps teams compare remediation and mitigation pathways before acting. The ecosystem includes AWS, Azure, CloudFormation, Azure Resource Manager, AWS GuardDuty, AWS Inspector, AWS WAF, Azure WAF, Cloudflare, CrowdStrike and Datadog, among others.

The published plans separate a 14-day trial from paid tiers that require contacting sales. The Free tier includes a written risk exposure assessment, one cloud project or account, configuration-only drift detection, limited AI prioritization agents and a single IaC. Security Teams adds runtime drift detection, unlimited AI prioritization agents, unlimited Security as Code, remediation and validation pathways and multi-cloud support. Enterprise adds unlimited mitigation pathways and integrations. ZEST suits cloud security teams that need contextual prioritization and guided remediation; teams seeking a permanent free plan or a simpler, narrower exposure tool should consider alternatives.
