The DMC Group accelerates project collaboration with Tresorit Engage — Saving a full day of work every week in secure, customizable data rooms
Project at a glance
Customer satisfaction in focus
As a cybersecurity consultancy, absolute security is the top priority for the DMC Group and that standard applies to how the team collaborates internally and externally. After all, how could anyone trust a company that advises on protecting sensitive data if it doesn’t maintain a secure tech stack itself?
With Tresorit Engage, the DMC Group has taken this principle to heart: project collaboration has become centralized, fully encrypted, and streamlined, saving the team roughly one full day of administrative work per week while ensuring that every interaction with colleagues, clients, and partners meets the highest security standards. On a six-month Municipalities engagement, this efficiency stacked up: saving one full week per month led to finishing 1.5 months ahead of schedule.
From day one of using Tresorit Engage, we’ve been very satisfied — and the same goes for our clients. But not just because it enables secure data exchange. The data rooms look professional, are user-friendly, and can be adapted to a wide range of scenarios.
About the company
Cybersecurity as a promise
Cybersecurity is more important today than ever before, as attacks continue to increase in both number and sophistication. To protect organizations, the DMC Group, based in the Netherlands, advises clients — from municipalities and government agencies to educational institutions and the healthcare sector — on security strategies and solutions. As a member of the Cyberveilig Nederland industry association, the company actively promotes quality and transparency in all matters related to security.
The challenge
Security — for data and projects
At the DMC Group, everything revolves around cybersecurity. It’s only natural that their daily work should also rest on a secure foundation. That’s why the consultancy decided a few years ago to manage data exchange via Tresorit SecureCloud — a solution that ensures unrivaled security through client-side end-to-end encryption with zero-knowledge. Its flexible sharing options and access rights management also make everyday data exchange easier. This allows the DMC Group to avoid depending on email infrastructure and workflows, which are not always fully reliable nor efficient.
Alongside Tresorit SecureCloud, the team also relied on a variety of other tools for messaging, note-taking, and task management. However, using multiple platforms created some fragmentation. The team wanted a single solution that could centralize all workflows with external clients and partners — bringing collaboration and security together in one place. And so, the search began.
At that time, Mick Deben, Cyber Security Consultant at DMC Group, received an email from Tresorit. Curiosity was quickly piqued — the message announced a new product designed to provide project-ready data rooms that can be turned into branded client portals, making collaboration with external stakeholders much easier.
As the data rooms are end-to-end encrypted with an intuitive interface, security and usability go hand in hand.
For several ongoing projects, Engage was implemented immediately to put it to the test. The interim conclusion after the first trials: Tresorit Engage, as a central hub to initiate, organize, and successfully complete projects, meets all of DMC Group’s requirements.
“It pays off to have a digital space where all workflows can take place. Currently, there aren’t many solutions capable of this — but Tresorit Engage provides customizable client portals where everything can be found and all project participants can stay connected.” explained Mick Deben.
Requirements
Secure, streamlined and user-friendly workflows with external clients
Through years of using Tresorit SecureCloud, DMC Group already knew that Tresorit’s Secure Cloud met — and even exceed — the highest security standards. However, it didn’t fully centralize workflows with external stakeholders or offer a professional, branded environment needed to seamlessly involve clients. This led the group to look for a new solution to manage confidential projects and client interactions safely and effectively. The requirements were clear:
- Data storage in the EU: The tense geopolitical situation made data sovereignty a top priority. For the DMC Group, the new solution had to be hosted in Europe to ensure compliance with European data protection regulations. Having worked with SecureCloud for years, the team already valued Tresorit’s flexible data residency options — now also available in Engage, which was a clear advantage.
- Building trust with clients: custom branding options to make customers feel more at home and make them more involved were also a criteria.
- Reduced complexity: Intuitive processes are also beneficial for stronger client relationships. Project collaboration should therefore be both secure and simple.
- Centralized collaboration: It’s common for one client to prefer tool A and another to prefer tool B. For the DMC Group, it was clear that collaboration needed to be centralized.
Implementation
Engage in practice with clients
The DMC Group quickly took advantage of the possibilities offered by Tresorit Engage. In a project involving multiple municipalities, all coordinated through a central supervisory board, the benefits of project-ready, customizable client portals became immediately apparent.
Workflows became significantly more efficient for everyone involved. DMC Group only needs to duplicate pre-created templates once during onboarding and grant access to the relevant municipalities to collaborate seamlessly on documents, review progress, and stay aligned throughout the project.
By centralizing information and project collaboration in a single data room, opaque email communication is no longer necessary. All participants are always on the same, up-to-date page.
“With Tresorit Engage, questions about task status or the latest document versions have become obsolete — everyone can access information clearly and centrally. It’s incredibly helpful and, most importantly, saves us time. Having one secure place where everything can be found and everyone involved in the project can stay connected is a real game-changer. There aren’t many solutions that can do that, and that’s what truly adds value for us,” explained Mick Deben.
Collaboration with partners
For consulting assignments, the company often relies on the support of external consultants. Collaboration and data exchange with them take place in separate data rooms.
For the municipal consulting project described above, additional data rooms are created that clients do not have access to. This way, project collaboration remains centralized in one place, while clients only see the information they truly need, such as final reports and analyses. Separating internal and external files and tasks is therefore effortless.
Results and feedback
External workflows made simple
Project work at DMC Group has been fundamentally transformed with Tresorit Engage.
Previously, the tool landscape was fragmented, and there was no single solution that combined security, user-friendliness, and efficient collaboration.
Today, the customizable client portals open to a main dashboard where all relevant information is collected. Status updates can be viewed, tasks can be managed, and individuals can be easily assigned to to-dos. Document sharing is highly secure.
These benefits have already proven convincing, and Tresorit Engage is now recognized within the company as the go-to solution for secure information sharing and efficient collaboration with clients and partners.
Customer onboarding drastically simplified
DMC Group carries out multiple projects for its clients. Thanks to Tresorit Engage, the workload is significantly eliminated. The team prepares templates in advance that reflect project requirements.
When a new assignment starts, responsible staff only need to create a data room from the existing template and allocate tasks and responsibilities. Time-consuming email communication and manual copying between storage locations are no longer necessary.
Time savings through centralization
Centralizing project work in data rooms radically reduces manual processes for status updates and information distribution. All participants can independently access information in the modern data room.
“All project information is stored centrally in the data rooms. This saves us a significant amount of time – we don’t need meetings or conversations about where the project stands. If they want to see the status they can just go to Engage — in fact, it saves us up to one full workday per week.” explained Mick Deben.
Over the course of longer projects, such as the six-month Municipalities collaboration, using Engage saved DMC one full week of work every month resulting in the project being completed 1.5 months ahead of schedule. Finishing early meant delivering under budget and with maximum efficiency, supporting the company’s growth while giving clients faster, more secure results.
Conclusion
From the start, DMC Group had a clear goal: project collaboration with clients needed to be significantly more efficient. Naturally, as a cyber-security consultancy, security could not be compromised while searching for the right solution.
In the end, extending Tresorit SecureCloud with Engage met all requirements. The project-ready data rooms offer maximum security, user-friendly design, and provide both transparency and efficiency.
