Schweitzer Klassifikation
Aaron Trompeter is a technical solutions architect within the ThousandEyes global enterprise segment at Cisco, focusing on visibility and operational awareness for onprem, SaaS, and cloud native. In this role, he aligns his passion for education and learning with his motivation for helping the infrastructure community grow and learn to harness tools to provide use cases that fit each organization. Prior to this role, Aaron spent 6 years as a data center TSA within Cisco and had a few other roles within Cisco as a service provider specialist and software engineer in the Cloud Engineering unit. Aaron has more than 20 years of experience in the IT and engineering areas and has continued to focus on networking and software.
Rob Webb began his technical career when, at 17 years old, he enlisted in the military as a teletype technician. His military service spanned more than 28 years, during which time he trained and worked in telecommunications systems, F-4 and F-16 avionics systems, and, eventually, Cyber Warfare Operations. Most of this time was spent working part-time in the Air National Guard. This allowed Rob to not only get the benefits of military training and experience but also to pursue a full-time career outside the military. He went from pulling cable to IT professional services to protocol analysis to pre-sales engineering/solutions architecture. Rob even ran his own consulting service, WEBNET Communication, where he achieved industry-recognized certifications in protocol analysis, which include Certified Network Expert (CNX), Sniffer Certified (SCM), and Certified NetAnalyst.
Rob has spent his career solving complex problems for customers and helping them design and implement monitoring solutions so they can better solve those problems themselves. He has spent many hours collecting and analyzing packets to understand not only what is happening in each situation, but also what should be happening and what can be done to improve it. He often refers to these as opportunities for optimization. Rob joined ThousandEyes as a sales engineer in March, 2020.
When Rob is not working, he keeps busy by enjoying outdoor activities such as fishing and photography. Now he combines the two in his sportfishing photography. You can follow Rob on LinkedIn (www.linkedin.com/in/robertwebbcyberguy) or Instagram (@photographyinspiredbylife).
