About NexGen Cyber

Our Approach

Our main focus, as a personable business, is to pride ourselves on being both reliable and honest towards both new and existing clients. We believe that in order to fully support and understand our client’s needs, we must connect with them fully.  This is only achieved by having a tight team who support each other, make time to eat together, have coffee together, plan together, review progress, and even share a drink together.  Our team are honest, reliable and trustworthy and are always prepared to work together.  Client relationships flourish when there is an element of trust and communication.  It is with this at our forefront that we are seen, by the external community, to be ethical, honest, having strong moral principles, great integrity and transparent, all of which are of utmost importance to enable us to provide our clients a next level service.

Our Mission

We believe that it is important to put ourselves into your shoes, and in order for us to understand your demands we must listen to our clients.  This is our USP, a client facing, personable and understanding team of professionals.  Our aim is to provide the best solution for our clients, and we strive to set the highest standards in all aspects of our work.  We understand that within the IT community things change rapidly, and we aspire to demonstrate this in our day-to-day delivery of our work. The always want to drive towards “the NEXT” great thing. We are always striving to challenge ourselves and therefore provide an excellent service to our clients.

Our Heart

With IT as our passion, we as likeminded professionals believe that having a strong positive team spirit enables the relationships to flow from company to client.  We understand that for business relationships to flourish you must build trust, enjoyment and entertainment are at the heart of our business.  We celebrate and embrace our diversity. We invest in each other because we win or lose as a team.

Our Comittment

As professionals we always demonstrate the highest attention to detail, be that through customer care, project management or delivery. We are always looking to move forward with new innovations and are prepared to reach out and trial new and often unconventional ideas.  We view honest failure as a learning experience in taking business opportunities to the next level.

Our Promise

In a fast pace working world, that is often seen as frustrating, confusing or even scary we pride ourselves on our humility.  We respect our customers, partners and co-workers and with this in mind we believe that these core values are reciprocated.  By being personable, open, honest and hardworking we are able to offer our clients the foundation for a great working relationship.

NexGen Cares: Hospices of Hope

It’s estimated that there are more than 50,000 children in Romania living with rare or life-limiting illness with 5,000 in the Bucharest area alone. With struggling and often corrupt healthcare systems, many of these children go with little or no help. Hospices of Hope Children’s Centre offers respite and therapy services to children with life-limiting and rare illnesses. As a business, we are proud to be sponsoring a child through this programme to help give them the life that they deserve.
