RMB Consulting vs A2e Technologies: overview

RMB Consulting

RMB Consulting has operated in embedded systems design and consulting since 1995, run by founder and chief engineer Nigel Jones, who brings more than 30 years of professional embedded systems engineering experience. The firm covers hardware, software, and firmware consulting with a team of 1 to 10 people, positioning it at the smallest and most direct end of the advisory spectrum on this list. Nigel Jones is also a recognized voice in the embedded engineering community through long-running technical blogging on firmware design topics, which gives a prospective client a substantial public track record to evaluate before ever making contact.

A2e Technologies

A2e Technologies was founded in 2004 and is headquartered in San Diego, California with a team reported between 11 and 50 engineers, commonly cited around 47. Beyond hands-on hardware, FPGA, and firmware development, the firm's anti-tamper hardware security design work functions as a specialized advisory practice for defense and space clients navigating threat-model and export-control requirements, under ITAR certification. For a buyer whose consulting need is specifically security-architecture advisory in a regulated defense context, that ITAR-certified anti-tamper specialty is difficult to find outside a handful of firms.

- A team of 1 to 10 people severely limits capacity for a large or multi-workstream engagement
- No published pricing or minimum engagement figure
- Availability may be constrained given the founder-led, low-headcount structure
A2e Technologies
+ ITAR certification is a hard prerequisite for many defense advisory engagements, and A2e holds it as a verifiable credential
+ Anti-tamper hardware security design advisory is a specific, uncommon specialty among general embedded consultancies
+ 21 years of operating history in aerospace, defense, and space engineering
+ Combines hands-on hardware, FPGA, and firmware capability with its advisory work, so recommendations can be prototyped by the same firm
- ITAR-focused positioning is a narrower fit for commercial-only advisory engagements without export-control requirements
- 11 to 50 employees limits capacity for the largest concurrent advisory programs
- No published pricing or minimum engagement figure
