You Should Know:
- The Aurora Superintelligence Platform: Redefining the Security Operations Center
Arctic Wolf’s Aurora Superintelligence Platform represents a paradigm shift in security operations, moving beyond traditional SIEM and MDR solutions. It combines massive real-world security data, specialized AI agents, and human-in-the-loop oversight to deliver speed, context, and trust. The platform is built on three core components: the Swarm of Experts, the Security Operations Graph, and the AI Trust Engine.
The Swarm of Experts is an agentic framework orchestrating hundreds of built-in AI agents across the full spectrum of SOC functions—from triage and investigation to response and threat hunting. These agents are categorized as Oversight Agents (coordinating and validating), Authoritative Agents (executing end-to-end security tasks), and Process Agents (automating repetitive SOC work). The Security Operations Graph serves as the platform’s intelligence foundation, ingesting more than nine trillion telemetry events weekly and drawing on over 14 years of operational data curated by more than 1,000 security analysts. The AI Trust Engine provides rigorous validation and guardrails, ensuring agents operate deterministically rather than generating speculative answers.
Step-by-Step Guide: Configuring Aurora Endpoint Security to Forward Events to a SIEM
To integrate Aurora Endpoint Security with your existing SIEM or syslog infrastructure:
1. Log in to the Aurora management console.
- In the menu bar, navigate to Settings > Application.
3. Select the Syslog/SIEM checkbox.
- Choose the specific events you want to forward to your organization’s SIEM or syslog server.
- The events are sent as Unicode plain text consisting of key-value pairs, separated by commas.
Linux Command: Testing Syslog Forwarding
To verify that syslog forwarding is working correctly from a Linux endpoint, you can use the `logger` command to send a test message:
logger -p local0.info "Test syslog message from Aurora endpoint"
Then, monitor the syslog server to confirm receipt:
tail -f /var/log/syslog | grep "Test syslog message"
2. NodeZero: The Autonomous Penetration Testing Platform
Horizon3.ai’s NodeZero is an agentless, autonomous penetration testing platform delivered as a SaaS solution. It operates inside your environment, continuously testing infrastructure, identities, and applications to uncover real attack paths and validate what can actually be exploited. NodeZero applies graph-based reasoning, deterministic logic, and scoped GenAI to think like an attacker, act with purpose, and help defenders fix what matters. Every action is explainable, and the platform can be deployed in minutes compared to weeks spent configuring other solutions.
NodeZero’s capabilities have recently expanded to include AI-powered web application pentesting, autonomously testing web applications and identifying attack paths that chain application vulnerabilities, credential theft, lateral movement, cloud access, and data exposure. It continuously validates real attack paths across internal, external, cloud, identity, Kubernetes, and hybrid environments.
Step-by-Step Guide: Deploying a NodeZero Host Using the Ubuntu Setup Script
To run an internal penetration test, you must first deploy a NodeZero Host within your network.
- Download the Setup Script: Obtain the Ubuntu setup script from the Horizon3.ai portal or documentation.
- Run the Script: Execute the script on a designated Ubuntu machine within your target network:
sudo bash ./nodezero-host-setup.sh
- Configure Network Settings: Ensure the NodeZero Host can communicate with the Horizon3.ai SaaS platform by configuring the necessary network settings. This typically involves allowing outbound HTTPS traffic to specific Horizon3.ai endpoints.
- Validate the Host: Use the validation tool to confirm the host is properly configured and can communicate with the platform.
./nodezero-host-validate
- Run an Internal Pentest: From the NodeZero Portal, create a new test, select the deployed host, and configure the attack options. You can enable or disable specific attack configurations to control the performance and potential disruption of the pentest.
Windows Command: Checking Network Connectivity for NodeZero
On a Windows host, you can use `Test-1etConnection` to verify connectivity to the Horizon3.ai platform:
Test-1etConnection -ComputerName api.horizon3.ai -Port 443
- Continuous Validation with the NodeZero CLI and API
For advanced automation and integration, NodeZero provides both a Command-Line Interface (CLI) and a GraphQL API. These tools enable security teams to schedule and manage recurring pentests remotely, eliminating the need for manual intervention.
Step-by-Step Guide: Using the NodeZero CLI to Trigger a Pentest
- Install h3-cli: Download and install the Horizon3 CLI tool from the documentation.
- Authenticate: Use your API key to authenticate with the CLI.
h3-cli auth login --api-key YOUR_API_KEY
3. List Available Tests: View existing test configurations.
h3-cli test list
4. Start a New Test: Initiate a pentest using a specific test ID.
h3-cli test start --test-id YOUR_TEST_ID
5. Monitor Test Status: Check the progress and results of the running test.
h3-cli test status --test-id YOUR_TEST_ID
4. Proactive MDR and the Concierge Experience
Arctic Wolf’s Managed Detection and Response (MDR) service provides 24×7 monitoring to help detect, respond, and recover from cyber attacks. Security telemetry is collected from internal and external networks, endpoints, and cloud environments. This data is enhanced by threat feeds, OSINT, CVE information, and account takeover data. Each customer receives the Concierge Experience, with security experts who understand the organization’s environment, priorities, and risks. This context-driven approach goes beyond a one-size-fits-all model to reduce risk, lower attack volume, and strengthen security posture.
Step-by-Step Guide: Configuring Active Directory Monitoring with Arctic Wolf MDR
- Deploy the Arctic Wolf Agent: Install the Arctic Wolf Agent on your domain controllers.
- Enable Active Directory Monitoring: In the Arctic Wolf portal, navigate to the MDR configuration settings and enable security monitoring for Active Directory.
