Julien TRASSARD, CEO, joined the LINKBYNET Group in 2002 to develop and structure the managed services project activity.

In 2005, he took over the management of the production site in Mauritius to launch the first worldwide operations before returning to Paris in 2007 to manage all operations and quality of the group. He launched the Canadian subsidiary in 2010, participating in the internationalization of the group, which is now present on 4 continents and in more than 10 countries.

Back in France since August 2019, he is dedicated to the growth and success of our customers' projects, particularly in support of offer definition, staff support and production programs for managed services and security.

Following my engineering degree in 2014, I chose to join Linkbynet Security. As soon as I arrived, I had the opportunity to work on a large number of cybersecurity issues and to follow several IT certification training courses, enabling me to work on high-stakes projects.

During these 6 years at Linkbynet I went from consultant to project manager and then project director for a large CAC40 bank before becoming a manager a year ago.

After an initial career in consulting, Marie joined Linkbynet 6 months ago as a Bid Manager in the Lille office. She works upstream of projects to identify the customer's needs and, together with the operational and sales teams, define the best solution to meet these.

She is involved in Linkbynet's development in Northern France, working to generate new opportunities for Linkbynet accounts in the region.

After 20 years of experience in the growth sectors associated with digital services, Bérénice has taken up a position in B2B services at Linkbynet on cross-functional projects that call on her multidisciplinary management and interpersonal skills.

Her objective? Listening to her clients is essential for meeting their digital transformation needs.

Passionate about security and with an engineering background in telecommunication and systems administration, Alexandre chose to align his career with the cybersecurity world.

He was able to join Securiview as a pen tester. Over the years, he has acquired enough experience to deploy different security tools at customers' sites.

Today, Alexandre is in charge of the integration and audit department at Securiview.

Réda specializes in Change Management for Service Management (ITIL V3 Foundation, DevOps Foundation and Scrum Master certification). Passionate about innovation and digital transformation, he also completed an Executive MBA in Management & Consulting in Information Systems at ESGI.

At Treeptik and Linkbynet, he has the opportunity to apply a life principle that he holds dear : "Find a job you enjoy, and you will never work again in your life".

Antoine joined LINKBYNET Cybersecurity following an engineering course at Telecom ParisTech/Polytechnique with a specialization in cybersecurity, more than 3 years ago. He started as a consultant, and quickly moved to project management.

Since last year, he has become the manager of a team of around 10 consultants.

Alexandre joined the Linkbynet adventure in 2009 as a systems administrator. By becoming a systems engineer, he was able to support his colleagues in increasing their skill levels, then, by advancing to the position of systems architect, built customer platforms.

Committed to the international growth of the company, in 2014, he fostered business development with the opening of an agency in Asia.

Passionate about new technologies and concepts, he finds new challenges in the cloud on a daily basis and brings innovation to his customers.

Today, Alexandre is responsible for the architect team.

After four years spent as a system and network administrator, Guillaume moved into technical architecture.

He designs on-premises architecture and supports clients in defining and implementing platforms. Guillaume carries out missions for large account customers, financial organisations, the administration and telecoms sectors.

Following technological advancements, he specializes in the Microsoft Azure public cloud and brings his expertise on the specifics of the public cloud to Linkbynets' customers.

After working for 10 years in a communications agency as a Technical and Digital Director, Jonathan joined Linkbynet a little over 6 years ago as a Key Account Manager.

Over time, he has worked on more and more accounts and supported/trained newcomers. Today, Jonathan is in charge of sales development in Île de France, and manages a team of 5 sales representatives.
