D3 SOAR vs StackStorm

D3 Smart SOAR automates security operations workflows and incident response as SaaS hosted by D3 or on-premises software. Its Event Pipeline normalizes, deduplicates, triages, and enriches alerts; D3 claims this can reduce events requiring human attention by up to 99%. A codeless playbook editor, ready-made library, and reusable automation blocks support response workflows. Smart SOAR integrates with hundreds of tools across SIEM, EDR, NDR, TIP, and ITSM categories. D3 says it will build missing integrations free of charge. Threat-intelligence reputation results enrich incidents and contribute to an overall risk score. Existing playbooks and integrations cover phishing, ransomware, and password resets. Full multi-tenancy supports managed security service providers and managed detection and response firms. The platform includes event triggers, scheduled runs, approval steps, incident integrations, and audit logs. D3’s customer-success program describes implementation planning, training, integration optimization, technical documentation, and Customer Success Manager support. Pricing is on request, with a demo request offered.

StackStorm is a free, open-source platform for integrating services and automating responses to events. Rules connect triggers to actions or workflows, and workflows can combine actions into multi-step automations. Sensors and actions link external systems; listed examples include webhooks, SSH, REST calls, OpenStack, Docker, Puppet, Sensu, and JIRA. StackStorm Exchange offers ready-made integration packs, and users can create and share packs of their own. Action records include triggering context and results, while audit logs can connect to Logstash, Splunk, statsd, and syslog. Administrators can use role-based access control to limit users’ access and operations. The platform includes a Web UI, CLI client, REST API, and Python client bindings. It is self-hosted and distributed as Linux RPMs and Debs or Docker images; deployment documentation also covers Vagrant/OVA, Ansible, Puppet, and Kubernetes. Supported systems are 64-bit Ubuntu and RHEL, Rocky Linux, or CentOS. Other Linux distributions, Windows, and Apple OSX are not officially supported. Listed uses include remediation, continuous deployment, ChatOps, and automated security response.
