Security operations, made useful.

I’m Sebastian Selig, an information security practitioner focused on Falcon LogScale and practical security operations. I work hands-on with firewalls, vulnerability management, email security, and operational security data. I build tools such as MyLogScale and UpdatePulse and document what works. This site collects my field notes, queries, and projects for security teams.
