Australian-based team

We never followed our peers who sought to provide cheaper rates by moving their Level 1 and Level 2 Service Desks overseas.  Although prices dropped, so did their service levels. 

It didn’t work and now the trend is reversing.  More and more clients are seeking out companies with Australian-based service desks because their current provider’s cheaper rates are being offset by the inefficiencies in communication and slow problem resolution.

We maintain 100% Australian-based technical staff.  They speak and write clearly with no international delay.  What’s more, if you’re a Complete Care Managed Services client, when you need someone on-site, we’ll turn up quickly and sort out the issue in-person.  

You can’t do that from a different timezone!

Two decades of experience

Computer One is the best part of two decades old.  Our client retention rate is strong and our processes are proven to work.

The team is made up of many senior engineers who have been with the company for more than 5 years as well as fresh-faced staff just beginning their IT journey.  Older staff mentor the younger ones in our values.

We have dealt with just about every industry and conquered just about every challenge in IT in our time.  And we’ve covered much of Australia too.  From the most high-tech data centres to outback mining operations and the muddy jungles of PNG.

When you’re looking to switch providers, we’d like to think we’re a strong candidate.

Our Security Experience

Picture this scenario:
Your senior system administrator has just had a boiling-hot argument with your CFO over some alleged improprieties and quit. 

It’s been coming for some time. On the way out, he sneers and says “good luck”… 

You immediately realise that he’s had weeks to prepare for this moment.  Who knows what kind of mischief he’s capable of, even after he’s gone?

All your data, your backups and your email system.  Even your phones.  What might someone with the right level of authority be able to do to interrupt your business?

It happens.  We know because we’ve been the company called in to immediately cut off his access, to find the holes that he’s placed in your network and fix the damage.  To provide our client with peace of mind that there’s no further risk. 

We’re a full-service managed security provider.  In the past we’ve forcibly taken over networks inside 24 hours of notification.  We’ve totally blocked malware like ransomware from operating on client systems.  We’ve been tasked with proactively identifying security weaknesses and repairing them before they’re exploited.  We train your staff to resist social engineering attacks and we provide regular updates on your security posture.

World-class Service is Standard

The international benchmark for client satisfaction with Managed IT Services is the Net Promoter Score.  It’s the same, standardised question no matter where you go: “On a scale from 1-10, how likely would you be to refer our service to colleagues and friends?”

We regularly test and benchmark our NPS against the best IT providers in the world, and our score rivals and exceeds them every month.  Our service levels are, quite honestly, World-Class.

We’re very proud and have worked hard to achieve it.  It’s your promise of excellent service.

If you’re looking for a company to trust with your Managed IT Security Services, you should speak with us. Our Australian-based team will delight you with our world-class service levels.
