IT Support Company In Johannesburg

HSC Systems is a turnkey IT support company specialising in 3-tier support for small to medium-sized businesses (SMEs).

What this means is that there is a primary, secondary, and tertiary assistance mechanism supported by a robust IT maintenance and monitoring framework.

The primary tier consists of onsite support, where our technicians visit the business with the IT query, and we help them in real-time.

Then there is the secondary layer, where we use AnyDesk or Team Viewer to remotely connect to a company’s VPN and follow a troubleshooting methodology that allows us to isolate and solve the query.

Finally, the third tier relates to the ongoing monitoring of business systems by HSC, such that we are able to find certain faults before they are reported.

Our company has specialised in cloud computing and IT support – including ancillary services – for over 30 years. We are accomplished in our service delivery with a 99% SLA as a standard.

Why Is IT Support Important In A Business?

Businesses have uptime and downtime measures and depending on the nature of your business, it may be the case that the more downtime you have, the more money you lose. This is particularly important in businesses where access to IT resources such as cloud computing, remote access, and VoIP telephony needs to be consistent. If any downtime happens in those hours of operation, critical errors could be made which ultimately affect ongoing projects, and in the end, the business’s bottom line.

Small business IT support is integral to HSC Systems’ business model because we believe that SMMEs are the engine that drives South Africa’s economy. As such, affordable IT support which is geared towards resolving issues in the most efficient and rapid ways possible should be a priority.
