How to Use This Catalog

This catalog supports executive review, industrial use-case evaluation, engineering assessment, deployment planning, and procurement qualification. It can be read online or as a self-contained printed document; access to a live product interface is not required.

Choose a reading path

Reader	Recommended path	What the reader should be able to decide
Plant manager or asset owner	Overview → Solutions → Deployment & Assurance	Whether the platform addresses plant risk, governance, and evidence needs
Operations and maintenance	Solutions → Secure Access → Protection & Evidence	How approved work is constrained and how resulting activity is understood
Control or protection engineer	Policy Engineering → Protection & Evidence → Deployment & Assurance	How equipment meaning, limits, commands, sequences, and prerequisites become qualified policy
OT cybersecurity	Secure Access → Protection & Evidence → Deployment & Assurance	How identity, lateral movement, industrial behavior, decisions, and investigation evidence are connected
Network and deployment team	Overview → Secure Access → Deployment & Assurance	Which enforcement path fits the traffic and operating model
Evaluator or procurement team	Overview → Solutions → Deployment & Assurance	What is delivered, what requires qualification, and what must be agreed before deployment

Six top-level catalog areas

Area	Purpose
Overview	Understand the product, business outcomes, architecture, and catalog structure
Solutions	Select an industrial problem and representative starting use case
Secure Access	Evaluate L2Proxy Connect, protected access domains, segmentation, and microsegmentation
Policy Engineering	Model equipment and turn approved operating intent into validated policy
Protection & Evidence	Understand decisions, stateful behavior, normalized events, and investigation evidence
Deployment & Assurance	Select deployment, operate services, qualify capability, and approve production use

How to interpret the content

Content type	Meaning
Product capability	A function delivered by the L2Proxy platform
Industrial use case	A practical way capabilities combine to address an operating need
Operational example	Representative behavior that makes the capability concrete
Protocol portfolio	Protocol-specific helpers, policies, stateful patterns, examples, and qualification guidance
Protected access domain	Managed user, session, network, and policy context serving one industrial purpose
Qualification requirement	Customer traffic, mappings, procedures, or acceptance evidence required for production use
Product boundary	A control or responsibility L2Proxy does not replace

Examples demonstrate product behavior and policy structure. They do not automatically authorize the same operation, threshold, timing, equipment mapping, or enforcement outcome at every site.

Recommended evaluation path

1. Select one consequential but bounded industrial use case.
2. Identify its users, equipment, points, operations, and expected sequence.
3. Confirm protocol visibility and equipment mapping with representative traffic.
4. Review the proposed Record, Allow, and Block outcomes with operations and engineering.
5. Select L2Proxy Connect or a standalone enforcement path.
6. Confirm that required North-South and East-West flows cross a managed enforcement point.
7. Validate normal, violation, timeout, replay, recovery, and failure-posture cases.
8. Approve deployment ownership, evidence retention, rollback, and change control.
