Grail vs LimaCharlie

Grail is a cloud incident-response pipeline from Grail Forensics, Inc. Six AI agents handle intake, endpoint evidence collection, analysis, validation, and reporting. The workflow uses Velociraptor on demand, reconstructs timelines from process, network, registry, and filesystem events, and maps suspicious behavior to MITRE ATT&CK. A validation agent checks findings against raw evidence and rejects claims not anchored to hashed artifacts. Reports contain an executive summary, technical appendix, and evidence index, with claims linked to source artifacts, lines, and SHA-256 hashes and chain of custody sealed end to end. Grail lists alert intake from Sentinel, Splunk, CrowdStrike, SentinelOne, and Elastic, with outputs to Jira, ServiceNow, carrier claims APIs, and custom webhooks. Evidence is tenant-isolated, encrypted with a customer-held KMS key, purged after delivery, and not used to train models. Pricing is capped per case and available on request.

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.
