About Obsidian Ridge

Obsidian Ridge is led by a CISSP-certified security practitioner with 10+ years of cybersecurity experience spanning the IDF, the Israeli Government Tax Authority, Deloitte, Varonis, and TEKRiSQ — currently leading Zero Trust Island Browser deployment for a Fortune 500 airline. Work spans individual protection, small business security, and enterprise environments.

The philosophy is simple: real people need real help, plain language, and practical security that fits how they actually live and work. No scare tactics, no bloated programs, and no reports that sit unread in a folder.

Every engagement is handled with confidentiality, direct communication, and a focus on reducing real risk without burying clients in jargon.

Across that work, the focus has ranged from security architecture and Zero Trust implementation to endpoint security, identity protection, compliance support, and incident response preparation. That includes hands-on experience with NIST, ISO 27001, PCI-DSS, and HIPAA-aligned programs, and work supporting organizations that needed security outcomes they could actually operate, not just approve on paper.

Obsidian Ridge exists because many buyers do not need a large consulting machine. They need a clear picture of risk, a practical plan, and direct access to someone who can explain both technical issues and business tradeoffs without turning the engagement into theater. That is true whether the client is a family trying to stay safe online, a growing business trying to close security gaps, or an enterprise team that needs depth where it matters.

The commitment behind the practice is straightforward: treat client trust seriously, communicate clearly, and do security work that earns its keep in the real world.
