About us

About us

When we formed Kontex in 2015, it was borne from frustration we felt having worked in the consultancy industry for some time.

We could see many of the challenges organisations were facing were compounded by the practice of selling more tools, large transformations projects and outsourcing key functions. And really, it just didn’t sit well with us. We wanted to do better. We knew we could prioritise the basics, leveraging organisations existing investments and provide the best talent for the challenge at hand. We wanted to create solutions, not problems.

We’re happy to say our vision for Kontex became a reality, our client-centric, engineering first approach where the client and success of the project was our greatest priority was well received. Allowing us to become an extension of their existing security teams and being able to offer unbiased advice.

Present day! We still operate this way.

We’re proud to say we work with some of the largest organisations in Ireland and globally, including numerous Fortune 500 companies spanning many industries including Financial, Life Sciences, Insurance, Telecommunications, Construction, State and Semi-State.

It makes us very proud to see what Kontex has grown to be today.  We have built a highly skilled team and our focus is to ensure we remain on the pulse of emerging technologies and trends enabling us to keep the best in breed service, continuing to deliver some of the largest and most ambitious cyber projects across Europe.

We have done so much already but really, we’re only getting started.  We’re excited for what is to come next.

Maybe we get to work with your organisation? Or maybe you get to work in ours?
