In the beginning

Net–Defence began our journey as a telecommunications company, through an acquisition in 1994. We were originally a division of Ogilvie Management Services, providing telecommunication installation and support to Ogilvie Construction and Ogilvie Fleet.  In the year 2000 the company changed its name to Ogilvie Communications Limited.

1999 – 2002

During the years of 1999 to 2002 Net-Defence saw steady growth in its turnover totaling 44%. Still focused on telecommunications we supported a wide and varied customer based providing hardware, installation, maintenance and training.

In the latter part of 2002 the company identified an opportunity for growth by entering in to the world of IT.   

2003 – 2004

In 2003 and 2004 we continued to provide outstanding telecommunication services whilst building a new set of IT service offerings. These services integrated well with each other, meeting the needs of our new and existing customers.


Towards the end of 2004, we were offering a wide range of services from occasional single solution and support through to fully managed telecommunications and IT Services.


As part of our growing business we acquired Comtec Business Equipment in 2007, this allowed us to increase our presence outside of Scotland as Comtec were based in the North East of England. This also us to expand our telecommunication expertise bringing market leader Samsung into our service offering. We were able to acquire existing staff who brought installation, customer support knowledge and experience into the business. Many of team remain with us today.

2015 – 2018

In 2015 the company changed its name to Net-Defence, this was to better represent the integrated telecommunications and IT services we now provided (and continue to provide).

During this period of evolution, the company consciously made a decision to provide secure solutions for IT and Telecommunication. If your infrastructure is not adequately protected your business is at significant risk.

As theses changes came to life, during the subsequent years our professional service division emerged. This team represents security and compliance to mitigate risk through testing, analysis, consultancy and certifications.

To further strengthen our integrated services offering Network Services was also added, providing telephone lines, broadband, mobile devices and connection.

Ogilvie Communications changed its name to Net-Defence in 2015.  We had a strong drive towards the security side of the business at this time whilst retaining our core IT and Comms business; one of the few companies to offer an end-to-end solution to business from  Cabling, Telecoms  (Including our own Lines and Broadband billing platform), IT Installs, consultancy straight through to aftercare and managed service.
