XM Cyber Exposure Management vs ZEST Security

XM Cyber Exposure Management is a subscription-based SaaS platform for finding and addressing validated exposures that create attack paths to critical assets. It continuously discovers CVEs, misconfigurations, and identity and access exposures across external, on-premises, cloud, and multi-cloud environments, using agent-based and agentless discovery. Its prioritization considers threat intelligence, exploitation likelihood in the customer’s environment, asset criticality, and business impact. Attack path analysis highlights choke points where remediation can remove multiple paths. The platform provides urgency and impact context, remediation guidance, alternatives, and validation. Cloud capabilities include agentless posture monitoring, vulnerability assessment for cloud hosts and containers, and visibility into permissions and their use. It can also discover shadow AI and map exposures affecting AI services, development resources, MCP servers, and agents. Integrations include ticketing, SIEM, and SOAR tools, with named connections such as AWS, CrowdStrike, Google SecOps, Microsoft Defender, ServiceNow, and QRadar. Pricing is on request. The company describes deployment as SaaS on Google Cloud Platform infrastructure by default for new environments.

ZEST Security is an exposure management platform focused on resolving vulnerabilities across cloud, code, containers, infrastructure as code, applications, and the supply chain. It simulates fixes and mitigations to identify resolution paths intended to lower risk with less effort. Its listed AI agents cover asset mapping, root cause analysis, prioritization, impact simulation, code generation, policy and guardrail analysis, and resolution building. ZEST supports AWS, Azure, and GCP, and says it has more than 50 integrations across security tools; named integrations include GitHub, GitLab, Terraform, Jira, Slack, ServiceNow, Qualys, Rapid7, Tenable, Snyk, and Wiz. The company says deployment takes minutes through a read-only cloud account and built-in connectors, and that the platform does not directly change cloud environments. It also says each customer has a separate tenant hosted in the US or Europe, customer data is not sent to external AI services, and its in-house language model runs within its AWS infrastructure. ZEST states it is SOC 2 compliant. Pricing is on request, with a 14-day trial; support hours vary by plan.
