But cybersecurity doesn’t reward longevity alone. It rewards outcomes, including safer organizations, stronger partners, and security models that actually work in the real world.

Create a Tenant, Deploy Sigma Rules, and Enable GitHub Sync with @claude Code and LimaCharlie

This video shows how Claude Code handles a full tenant setup in a single workflow: creating a new organization, deploying Sigma rules, and enabling Git Sync, all in one run with LimaCharlie. Claude Code creates the organization, deploys the community Sigma rules available on the platform, and configures the Git Sync extension. That extension automatically creates a GitHub repository and syncs both the detection rules and the full tenant configuration to it, giving you version-controlled infrastructure from day one.

Reduce False Positives Automatically with @claude Code and LimaCharlie

Noisy alerts slow down every SOC. See how Claude Code with LimaCharlie can analyze your existing detection logic and trigger alerts to identify what's generating the noise and what can be done about it. After running the prompt, Claude Code reviews your rules and their trigger frequency, identifies the ones generating false positives, and produces specific recommendations for suppression rules to apply. In this example, it flags three rules and provides the logic to address each one, whether the issue stems from a syntax problem or detection logic that needs tightening.

From Threat Article to Deployed Detection Rules Automatically with @claude Code and LimaCharlie

When a new security incident surfaces, threat intelligence is only useful if you can act on it quickly. This video shows how Claude Code, combined with LimaCharlie, compresses that gap significantly.

1,500% Surge in New Malware: Why MSPs Must Act Now

The latest findings from WatchGuard Technologies reveal a stark reality for managed service providers: cyber threats are not only increasing—they’re evolving faster than traditional defenses can keep up. In its newest Internet Security Report, WatchGuard identified a 1,548% spike in new, unique malware from Q3 to Q4 2025. Nearly one in four threats bypassed signature-based detection, highlighting a critical gap in reactive security models still used across many customer environments.
