In their own words
Cydarm
Cydarm is a cyber incident response management platform for security operations teams. It combines case management, data enrichment, editable playbooks, reporting, collaboration, and response-time SLAs. Teams can assign tasks using an open-source playbook format, while attribute-based access controls restrict visibility from whole cases down to individual comments or data types. Listed integrations include OpenAPI, email polling, webhooks, Jira, ServiceNow, Teams, PagerDuty, Slack, and SMS. Cydarm is offered as a hosted managed service or an enterprise deployment on a customer’s infrastructure, with web, API, and self-hosted platforms. It supports SSO through Microsoft Entra ID, Okta, Google, and AWS, with no SSO fee. Cydarm Technologies states it meets ISO 27001:2022 requirements and has achieved certification. Security information describes disk encryption, TLS 1.2 or higher, dedicated hosted infrastructure, and network segmentation. Pricing is on request; a 30-day trial costs nothing and needs no credit card.
GRR Rapid Response
GRR Rapid Response is an incident response framework for remote investigation and live forensics. Client agents run on target systems, while server infrastructure provides a web interface and API. From the framework, analysts can search and download files, search the Windows registry, access raw filesystems, and collect forensic artifacts. GRR also supports remote memory analysis with YARA and lets analysts schedule fleet hunts, including for machines offline when a hunt is scheduled.
The integration list includes Colab, Splunk, BigQuery, Elasticsearch, Timesketch, Turbinia, Python API clients, and an HTTPS REST API with OpenAPI definitions. The maker says client-server communication is encrypted against eavesdropping and impersonation; approval-based controls can gate sensitive actions. GRR is self-hosted, open source under Apache License 2.0, and listed at free. Clients normally run as root and can read system data, so access to the server carries equivalent access to client machines. The core team does not offer a helpdesk, paid setup assistance, feeds, or consulting.
