IT for professional services firms: confidential, stable and accessible anywhere
If your professional software isn't working, it directly costs billable hours. We provide a stable environment in which client data is well protected.

IT for offices where trust comes first
For accountants, lawyers, consultancies and other service providers, IT is the backbone of the work. If a professional application isn’t working, it directly costs billable hours. And if client data is leaked, your reputation is at stake.

Our approach
How we help your office
Professional applications that simply work
Your applications for accounting, client files or CRM are indispensable. We make sure the environment around them is stable, and liaise with your software supplier when something comes up.
- A stable environment for your professional applications
- Coordination with your software supplier on updates and outages
- Fast access, at the office and at home
- Less downtime, so more billable hours
Confidential data well protected
Clients trust you with their most sensitive information. A data breach affects your clients and your reputation. We set up your environment so that confidentiality is a matter of course.
- Sign-in with two-step verification
- Encrypted laptops and secure remote access
- Permissions per team or client file, only for those who need them
- Help with your GDPR obligations
Productive anywhere, also when working hybrid
Your team works at home, at the office or at a client's premises with the same files and applications, without compromising on security.
- The same workplace at the office and at home
- Meeting and collaborating in Microsoft Teams
- Calling from your landline office number, also on the go
- Security that travels with your laptop
Working smarter with AI, without risk
AI can save a lot of time, for example when summarising meetings or drafting a first version. But with confidential client files, that has to be done responsibly.
- First get permissions and sensitive client files in order
- Copilot within your own secure environment
- Clear agreements on what is and is not allowed
- Starting with a small pilot group
In practice
A working day, at the office and at home
This is how your team stays productive anywhere, while client data remains protected.
Plan an introduction- 08:45
Sign in at home, get started straight away
With two-step verification you sign in securely and open your professional application and client files, just like at the office.
- 11:00
A client submits documents
Using a secure link, the client uploads their documents directly into the right client file. No more attachments in your mailbox.
- 14:00
The meeting has already been summarised
After the client meeting, Copilot lists the agreements, within your own secure environment. You check them and record them in the client file.
- 17:30
Everything securely closed
Your laptop locks automatically when you walk away, and your data is secured in the backup overnight.

Frequently asked questions
Questions about IT for professional services firms
Is your question not listed? Feel free to call us, we are happy to think along with you.
How do I secure confidential client data at the office and at home?
With a combination of measures, including two-step verification, encrypted laptops, limited permissions per client file and secure remote access. We set this up as standard, so your team notices little of it in their daily work.
How do I share confidential documents securely with clients?
Instead of emailing documents as attachments, you use secure sharing links with an expiry date. Clients can also submit documents securely. That way you stay in control of what you share with whom.
Will our professional applications still work if we move to the cloud?
That depends on the application. Many professional applications already run in the cloud or work well with Microsoft 365. Together with your software supplier, we look at what the best solution is.
Is Copilot safe for confidential client files?
Copilot works within your own Microsoft 365 environment and with the information an employee already has access to. That is why we first make sure permissions on client files are set up properly, before you start using Copilot.
Do our professional applications and Adobe Creative Cloud work well with Microsoft 365?
In most cases, yes. We provide a stable environment, the right licences and secure links between your software packages and Microsoft 365. For creative work, we recommend workstations that are powerful enough for Adobe Creative Cloud.
