Gateway Architecture & Protocol Expertise

Turn difficult protocol and gateway requirements into an architecture that can be built, operated and extended.

We work across SSH and its application protocols, HTTP/1.1, HTTP/2, HTTP/3, QUIC, TLS, DNS and content-adaptation protocols. The objective is not merely standards compliance, but interoperable, observable and policy-aware production software. Earlier work includes contributing to ICAP/1.0 and RFC 3507; current Cloud Fellows products include independent SSH and QUIC implementations.

Our experience spans gateway appliances used by thousands of customers, globally distributed cloud services and compact embedded components. We design for clear extension points, low operating cost, controlled dependencies and policy processing close to the data path.

An engagement can integrate Cloud Fellows software assets, extend one of our gateway products or address the requirement entirely on the customer's technology stack. Focused workshops, feasibility studies and proofs of concept can establish the right direction before a larger commitment.

Architecture Review & Project Leadership

Independent technical judgment, followed by practical help turning decisions into delivery.

We examine system boundaries, data and policy flows, performance, dependencies, failure handling, operability and implementation quality. Findings are translated into prioritized risks and an actionable engineering roadmap.

Cloud Fellows can stay involved after the review: shape the plan, guide technical decisions, lead an initiative, support implementation and help teams resolve difficult engineering issues. The track record ranges from focused expert groups to leadership of global organizations with more than 500 engineers.

Good architecture must support product strategy, customer workflows, delivery processes and sustainable operating cost. Experience as architect, engineering executive and managing director helps connect the technical recommendation with the organization that must deliver and operate it.

Projects Delivered by Cloud Fellows

Outsource a defined component, integration or product initiative and receive working software plus the knowledge needed to own it.

Cloud Fellows can design and implement the solution, validate it in realistic operation and transfer the software, documentation and knowledge back to the customer. Scope can range from a protocol component to a complete gateway initiative.

Core strengths include modern C++, asynchronous networking, cross-platform development for Linux, macOS and Windows, test automation and systems with minimal external dependencies. AI-supported development accelerates analysis and implementation while expert review, testing and release gates remain responsible for quality.

SSH Gateway and Web Gateway demonstrate the complete path from protocol research and architecture through implementation, interoperability work, packaging, documentation and release. They are current evidence of delivery capability, not only experience inherited from earlier roles.

Security Gateway Assessments

Understand what a deployed gateway protects, where modern protocols create gaps and what to improve next.

We review traffic paths, deployment architecture and protocol handling, including whether HTTP/3 creates an inspection bypass or a loss of policy consistency. The assessment can combine design review with controlled protocol and interoperability validation.

Review areas can include TLS and certificate handling, policy enforcement, authentication and routing, logging, health monitoring, failure behavior and operational resilience. Scope is adapted to the customer's environment and risk priorities.

The result is a clear explanation of findings, prioritized risks and practical recommendations rather than a generic checklist. Where useful, Cloud Fellows can continue with architecture guidance, proof-of-concept work or implementation support.

Why Cloud Fellows?

The name reflects the Fellow role held by founder Martin Stecher at McAfee and Skyhigh Security: a senior technology leader, trusted advisor and industry expert. Cloud Fellows brings that standard of partnership to customers and collaborators.

Martin has worked in software engineering for four decades and in web and cloud security for more than 25 years. His background spans product architecture, standards work, global engineering leadership and managing-director responsibility.
