Cloud Connectivity Delivering your business productivity and agility

For your business to succeed, individuals and groups must connect with applications securely across various platforms.

We help improve business productivity, agility, and cost-efficiency by developing effective SD-WAN solutions to enhance user experience and control traffic.  Utilising our hybrid networking model, we deliver the predictable, low-packet loss, private and reliable backbone provided by MPLS while simultaneously aggregating bandwidth and reduced operational costs using SD-WAN, without compromising high-quality performance and security.

Unified Communications Driving profit through greater collaboration

Keeping your teams seamlessly connected with each other and your customers to drive greater collaboration can help you increase profitability. Research from Deloitte states that companies that unlock a collaborative crowd’s power through unified communications are twice as likely to be profitable.

We help improve the way individuals and groups interact with internal and external stakeholders across multiple devices through establishing effective unified communications that are easy to use. These solutions make connections seamless, transparent and without interruption and can be implemented across voice, video, team messaging and content sharing.


Data Service Securing mission critical assets cost effectively

As your organisation grows, it often becomes unsustainable to keep IT equipment in your offices. As well as overheads such as power and maintenance, it can be hard to maintain an ideal temperature for your servers. A far more manageable and safer approach is to reside offsite in a secure dedicated data centre facility permanently.

Our data centre facilities are engineered to support the highest levels of security and availability for your mission-critical applications, hosting IT infrastructure and intellectual assets. Located in Australia, our cost-effective data service offering not only keeps your data onshore, but in a 24/7/365 monitored Tier 3 data centre that complies with the highest regulatory guidelines.
