How we help
Mergers
Merging two or more businesses presents a unique set of challenges to your IT function. What appears to be a single organisation is often a host of different companies working as a single unit. Removing this digital divide enables all businesses within the group to collaborate effectively. Let Naro Blanco show you how.
Divestitures
Running an efficient operation after an acquisition relies on seamless IT – and working across multiple tenants can cause significant challenges for businesses that are otherwise unified. No matter how large your organisation, or how great your challenge, talk to us to discover why even the most complex migrations to cloud-based Microsoft IT is what we do best.
Acquisitions
Simplifying your business through divestitures presents the perfect opportunity to ensure your IT function is flawless. Unite your newly streamlined team behind a robust and reliable IT set up that works for the business you are today… and the business you strive to be tomorrow.
Our clients
Our clients range from growing businesses to established organisations across multiple industries. We work closely with each client to understand their unique needs, delivering tailored solutions that support compliance, efficiency, and long-term success.
What our clients say
"The project was completed quickly and effectively. What few issues there were with the migration were met with great support, and reassurance that a solution would be delivered swiftly. The knowledge was there, and delivery was checked and measured at every milestone. Minimal Post-migration support was required, due to the smooth nature of the migration, and the great level of response to emerging issues.We really appreciated that everything went as promised, with no post-migration headaches. Based on our experiences with other specialists we were most impressed with the level of professional planning and expertise from Nero Blanco, and we would definitely recommend them and use them again for future projects.”
- IT Support Engineer, Signal
"Nero Blanco enabled us to under-promise and over-deliver on what was a challenging and vital transformation project. From a design perspective, their expertise allowed us to understand the viable options and to shape the most sensible solution for our organisation."
- Head of Technical Architecture
“From Nero Blanco’s early involvement through to completion of the project, project lead, Conrad Murray, and the team demonstrated a vital understanding of the cultural issues and etiquette inherent in working with a Japanese organisation – something many vendors overlook.They were delightful to work with, and there’s no doubt in my mind that the project wouldn’t have gone as well without them. I can’t recommend Nero Blanco strongly enough and wouldn’t use anyone else in future.Senior management in Chugai Japan are delighted with the end result, as are the management teams in Europe and US.If you’re thinking of carrying out a Microsoft 365 migration for your business, I’d strongly recommend making sure you have the right partner – in the form of Nero Blanco – on your side. It makes life a whole lot easier.”
- David Howell, Head of IT Europe, Chugai Pharma Europe
"Traditionally, and for many years, RNIB has partnered with other organisations and charities that complement the work we’re doing to help visually impaired people. In our most recent restructure, we decided to rehome these organisations – divesting them to other charities that can provide ongoing support so we can focus on our core activity.The discovery process for these divestitures was done by Nero Blanco as part of the ongoing retainer. Each individual process is then priced up as a separate project, and delivered in collaboration with the internal team.Nero Blanco have already helped us to divest five to six organisations, with another three to four still to be processed. Some are relatively small projects, while others – such as the divestiture of Loughborough College to Sense Scotland – are more complex, requiring VPN access and the move to a new server. Yet whatever the size of the project, all require the same smooth transition with minimal impact and disruption to the people involved.In the case of Loughborough College, one RNIB staff member transitioned across to manage the handover, which was super smooth and interruption-free. Without the experience, resources and support of Nero Blanco, we would have struggled to manage the divestiture process. It’s good to have their ongoing support and expertise on hand when we need it."
