About Sigma Squared


Sigma Squared can trace its roots back to 2004, starting as a freelance desktop support business to numerous small businesses in and around the East Rand, Johannesburg and Pretoria areas.

Initially offering technical support, web hosting and software support, Sigma Squared grew its competence in many fields, culminating in a unique outsourced IT support service.

After a few years, Sigma Squared tailored its services to provide key advisory to a niche group of clients, managing infrastructure, hosting, and advanced project support on both Linux and Windows operating systems.

Fast forward to 2015, and Sigma Squared had become a key advisor, along with industry partners, to many SMME (Small, Medium and Micro-Enterprises) clients across Johannesburg and Pretoria, offering detailed audits and infrastructure advisory services.

At Sigma Squared we pride ourselves in our core values of Knowledge, Integrity, Strategic Benefit and Customer Centricity.

Please browse our site, and feel free to contact us with any enquiries you may have. We highly recommend an audit of your infrastructure as a starting point, as you cannot manage what you cannot see.
