I have had the good fortune to work with Christophe Casalegno on strategic projects, both in my entrepreneurial ventures and as head of a CERT, and his commitment to Open Source has always impressed me. His expertise and professionalism, particularly in managed services, have been major assets in ensuring the success of our initiatives.

His trust in supporting me on strategic projects reflects his collaborative spirit and his ability to bring the right skills together around the right objectives.

“I don’t think I’ve ever met anyone so committed to seeing his undertakings through properly. He has accumulated an incredible amount of knowledge, making him VERY highly skilled in his field.

Cyprien Wacogne.
IT Consultant & Trainer at Intredys
“After a Better Call Brain session that was just right, with unparalleled expertise and endless kindness, we called on his expertise. No disparaging remarks, no inappropriate comments about what had been done badly, or at least not properly: he explained, step by step, what was wrong and, above all, how to fix it. Endless patience, with a healthy dose of teaching skill. Thank you, Christophe!”
Yohann Croizat.
European Omnichannel Director (Upergy)
“This man is a superhero. He did not hesitate to take over my project, which was technically a minefield, and managed to keep our platform running against every prediction from the leading experts. Well done, and thank you. I will never forget it.”
Benjamin Rollet.

Christophe is very creative and very responsive. He helped me a great deal, even when the problem sometimes lay more in the applications than in the hosting itself. I thank Christophe for his availability and generosity.”

He trusted me and showed me the way forward. Thank you.”

Having tried several managed services and hosting providers, he is by far the most capable and available person I have encountered.”

Jerome C..
Ministry of Defence – confidential
“It is difficult to recommend Christophe without revealing his immense capabilities and the references that are subject to a degree of confidentiality. All I can say is that he is undoubtedly one of the best experts I know. He can deal with intrusion threats in practical terms and define credible action plans. Finally, his ability to anticipate and his constant questioning of his own approach to mastering new technologies undeniably place him among the best in this field.”
Cedric Gautier.
Senior Webmaster French Tech
“I called on Christophe when I had very specific hosting and security requirements, and he met my expectations perfectly. I also had the opportunity to meet him in person, and I have excellent memories of that meeting. Very PROFESSIONAL, highly recommended.”

Cedric Moullet

« As far as I can remember, I was the first client of Christophe Casalegno. I’ve known him professionally for about 20 years now and I’ve always been impressed by his knowledge on IT and all the subjects that relate to computers and networks. I would recommand him for anything linked with digital technologies, networks, security and science. Maybe the most clever and smart person I know today. »
Romain Bouiller
CEO of Mr Bot and Trizzy
“Above all, Christophe is passionate about what he does, and it comes through every day in our conversations.
As well as being a true expert, he is completely at his clients’ service and available at any hour to advise and support us with all our needs.
It is a real relief to entrust our infrastructure to Christophe, who has stepped in several times in record time to handle emergencies.
Like him, his teams are just as responsive and professional.
A true partner to Mr Bot. I recommend him with complete confidence!”
Willy Coupry
Solution sales specialist (Multicloud services) at IBM Services
“Christophe is not only passionate, but formidably tenacious when projects of great technical complexity come along.
I have never known anyone who gives so much of himself (day and night) out of sheer conviction that a project will succeed… It commands admiration.
Beyond his expertise and technical ingenuity, he has a sharp business sense and knows how to pick his battles.
To top it all off, it is a real pleasure to work and talk with him, always in good spirits and with warmth!”
Eric Portelli
Business Evangelist, ex Carmen Steffens Europe and Middle-East CEO
“I first knew Christophe as a friend, and later came to appreciate his expertise in information systems and his many other talents, particularly in marketing strategy and overall strategy. I wish I had listened to him a little more: he would have saved us time and money. In particular, with a few targeted actions, he demonstrated his ‘firepower’ in communications (yes, he does more than just data…). He is the ‘lethal weapon’! I think Christophe is someone who cannot sell the same product to everyone… he would get bored :-) Christophe is an extraordinary observer who can deliver what you need, even when you do not necessarily know it yourself. Now, is he a businessman who has always dreamed of being an artist, or the other way round? I think that will remain ‘the question’ all his life, and that is what makes him different and endearing.”
Gabriel Flory
Platform Manager at NETCO SPORTS, ex Affility / Bonzai Digital CTO
« Christophe won’t let you down, and make your service up and running in a high availability way. He will never pretend to know your buisness more than you do, instead he will learn, understand, and adapt to make his solutions fit your needs. On top of that he is a great person to work with and and an all-around nice fellow with whom you’ll enjoy lengthy tech chats if you are tech-savvy enough. In a context where we had limited fundings and a crude non working app from a SCSC Christophe managed to get us to a high-availability scalable application handling tens of millions of requests per day. »
Pascal Messana
Entrepreneur, founder of Blog4ever.com, Jolishare.com, Sitovisto.com
« Christophe is an expert in web-servers. He is creative and knows well how to adapt his offer to his clients. He is also a hard worker, obsessed by getting the best results in term of performance. »

Cédric Moullet

Beyond his obvious expertise, his availability and the relevance of his choices, Christophe Casalegno enabled us to test innovative, effective solutions suited to our organisation. His service evolved to cover management of all our IT equipment, hosting, server provision, backups and network security, gradually forming a comprehensive, coherent service. Christophe understood the evolution of our SME, and our collaboration over this period was fruitful and enjoyable. I consider Christophe Casalegno the most competent person I know in this field.”
