LimaCharlie vs OpenText Enterprise Security Manager (ArcSight ESM)

LimaCharlie is an API-first SecOps platform for telemetry, detection, and response. Its endpoint tools gather EDR telemetry, monitor process, network, file, and user activity, and support YARA scans and automated response. The endpoint agent supports Windows, Mac, Linux, Docker, ChromeOS, Chrome, and Edge. LimaCharlie can ingest structured JSON, Syslog, or CEF data, including on-premises sources and cloud-to-cloud feeds. Users can define detection criteria and response actions in YAML, then automate actions across endpoints, APIs, clouds, and multiple tenants. Rules, sensors, and configurations can also be defined in YAML or Terraform with version control, auditability, and rollback. Multi-tenancy is designed for MSSPs to separate customer environments while centrally managing rules, sensors, and automation. The Community tier is free and allows up to two endpoints. Standard lists EDR at $3 a month per endpoint. The pricing page lists SOC 2 Type II, GDPR, CCPA, and PCI-DSS under security and compliance.
