Company Overview

RJ45 was established in 2009 with a small office of six employees nestled in the back of a warehouse in Paarden Eiland. Founded by Doron Shmaryahu and Riaan du Toit, the company was born out of a desire to address something we felt the industry was sorely lacking… great service.

With existing business relationships of over fifteen years we were able to extensively grow our client base. To this day, we still count many of these clients among our most valued business partners. Our success has been built on strong one-on-one relationships, developed over years of dedicated, hands-on service.


With our ongoing journey to success, we quickly found ourselves in need of a bigger office for our growing team. Today we are located in Northgate Business Park just outside of the city.

At RJ45, we focus on cultivating a strong team spirit and supportive workplace environment, ensuring that our technicians and engineers remain encouraged to further develop their skill sets. By keeping the team up-to-date with the cutting-edge in emerging technologies, through continuous learning and in-house training, we can offer our clients the best level of support and client-focused solutions.


Since RJ45’s conception in 2009, we have built a comprehensive network of reliable and dedicated partners best suited to the unique South African business climate.

We are certified partners of Fortinet, Riverbed, Microsoft, Natunix and Trend Micro.
