Numberline Security

What Numberline Security does

Numberline Security is a privately held cybersecurity advisory firm operating as Numberline Security, LLC, headquartered in Boston, Massachusetts. The firm specializes in Zero Trust security strategy, education, and advisory services for enterprise clients, Managed Service Providers, and security practitioners. Its central intellectual property is the Zero Trust Blueprint, a four-phase methodology (Assessment, Strategy, Roadmap, Execution) supported by the proprietary ZTMM+ maturity model (an extension of CISA's Zero Trust Maturity Model) and the NextGen Identity Framework. Numberline is founder-led by Jason Garbis (CEO) and Jerry Chapman (CTO), who co-authored "Zero Trust Security: An Enterprise Guide" (Apress/Springer) and serve as co-chairs of the Cloud Security Alliance Zero Trust Working Group.

The company's product portfolio is methodology- and education-centric rather than software-centric. Revenue-generating offerings include high-touch enterprise advisory engagements (Zero Trust assessments, blueprint creation, Identity QuickStart, ongoing identity advisory) sold via direct enterprise sales with six-figure deal sizes; self-paced digital training courses priced at $495–$650 (A Practical Approach to Zero Trust and Zero Trust for MSPs workshop) distributed through a Podia storefront; downloadable self-assessment kits and e-books priced at $9.99–$450; and a free online Zero Trust Readiness Assessment used as a lead-generation funnel. The firm maintains a content-driven marketing motion through its Absolute Zero Trust newsletter, published books, blog, CSA working group leadership, and Mastodon presence.

Numberline operates with a small team (1–10 employees) and is currently hiring commission-only sales representatives to scale enterprise pipeline. It is founder-owned with no disclosed external funding, M&A activity, or parent company. The stated track record covers "dozens of enterprises" served globally through advisory engagements, with no named customer logos or disclosed financials in source materials.

Core offering

Numberline Security provides strategic Zero Trust security advisory and education services to enterprises.

Product overview

Numberline Security provides strategic Zero Trust Security education and advisory services, not a unified software product. The core offering is the Zero Trust Blueprint—a structured four-phase methodology (Assessment, Strategy, Roadmap, Execution) that guides enterprises through Zero Trust implementation. This framework is supported by multiple products: self-paced training courses (A Practical Approach to Zero Trust: Part 1: Planning and Zero Trust for Fun and Profit: A Workshop for MSPs), self-assessment tools (ZTMM+ Self-Assessment Kit and Zero Trust Readiness Assessment), a digital book (Getting Started with Zero Trust), and advisory services (Identity Quickstart and Ongoing Zero Trust Identity Advisory). The products are complementary, with the Blueprint serving as the overarching methodology and the training courses and tools providing practical implementation support.
