The game has changed, clearly. Attackers have AI, defenders have AI, and both sides are learning faster than anyone expected, or maybe the attackers are just a bit faster. What used to take hours now happens in seconds, and detection windows close before alerts even appear. It’s adaptation beyond automation, and no one gets to sit still. But every promise of AI-driven defence comes with a price. The tools are expensive to train, maintain, and monitor. Mistakes cost more too. False positives drain teams, model drift hides real threats, and poisoned data turns protection into confusion. So now it’s not only about defending networks, it’s about defending the defenders themselves, from fatigue, blind trust, and automation gone wrong. So how do you keep visibility when both sides use the same weapons? How do you detect intent when patterns look human but aren’t? How do you justify cost when failure still happens, just faster? Let’s explore what happens when algorithms face each other on both sides of the firewall, and what new defences emerge when speed alone is no longer enough. A closed conversation about a future where cybersecurity becomes an AI vs AI battle, and humans still have to win.

For banks, insurers, and other financial services leaders, core modernization is rarely a simple technology decision. The harder question is what to replace, what to wrap, what to rebuild selectively, and what to leave alone. This round table brings together senior peers to discuss how they are making those choices under real constraints: resilience, control, regulatory scrutiny, delivery speed, vendor dependency, and the risk of getting sequencing wrong. The conversation will focus on practical judgment, where modernization creates value, where it adds risk, and how to move forward without triggering another multi-year transformation cycle. A small-group discussion for leaders looking for clear decisions, credible trade-offs, and peer perspective.

Every vendor swears their platform is open, flexible, and built for freedom. Then comes the renewal date. The price goes up, migration looks painful, and “strategic partnership” starts to feel more like dependency. Most organisations don’t get trapped overnight, they walk into it one contract at a time. Broadcom, anyone? We know lock-in isn’t only technical, it’s commercial, architectural, and even cultural. Once tools shape how teams work, switching becomes not only costly but politically impossible. So how do you manage dependency without losing leverage? What do you do when moving away costs more than staying? How do you negotiate from a position of weakness? And what governance models help prevent lock-in before it happens? Let’s share how to keep options open, make vendors compete without breaking partnerships, and find leverage even when it seems there’s none left. A closed conversation for those who’ve learned that freedom in IT is rarely free.

The cloud engineer’s world keeps expanding. It started with provisioning and automation, but now it touches everything: resilience, security, cost, and even business continuity. What used to be a back-end function has become one of the most visible roles in digital operations. Yet with that visibility comes pressure: constant evolution, constant firefighting, and very little time to step back and ask, “Where is this career actually going?”

Arxus ensures that Resengo's reservation system is permanently available
Resengo is a Belgian digital company that develops online reservation systems. Primary target groups are restaurants, wellness centers, and sports & recreation facilities.The company has experienced significant growth in recent years. Resengo is now working on a new IT architecture to eventually transition completely to Microsoft Azure.
Resengo is a Belgian digital company that develops online reservation systems in-house. Primary target groups are restaurants, saunas & wellness centers, and sports & recreation facilities. Through their proprietary platform, Resengo registers more than 3.2 million online reserved place settings for restaurants, every month. Typically, for Resengo, companies put forward a complete offer: the actual reservation system with both the associated back office and the necessary plug-ins to link their customer's website with the system. For example, to find a restaurant nearby where you can make reservations through Resengo. In recent years Resengo has chosen to further develop their software with new automated marketing techniques, including inbound marketing. Their prospects can, for example, onboard themselves with a free trial version of our software. Our software has also been further developed with a Match & Go feature. This means that we bring the right guest to the right catering facility with the goal of providing a positive review of the customer to his/her contacts.
The success of our product depends on its availability. At Resengo, availability is closely linked to scalability. Arxus ensures that the applications are always available. This allows us to focus entirely on the development of the offering.Dirk Gypen: (CEO) - Resengo
In recent years, Resengo has experienced significant growth. The company now has over three thousand customers and registers/books 6 million place settings every month. Over 3 million of these are booked online. Across all sectors, this amounts to nearly 3 million reservations every month. Behind the scenes, Resengo often needs to move quickly. This has proven to be a problem in the past. Resengo was unable to cope with this itself and also did not have the possibilities to develop the necessary expertise itself. This year marks Resengo's nineteenth anniversary and all development is now done in-house. The ongoing challenge, therefore, is to ensure that older technology is continually replaced with new technology. All new applications are built entirely in the cloud. In the near future, Resengo aims to also migrate all the legacy code they are still using to cloud technology.
Resengo did not consider immediately moving everything to the cloud as the best option. For the time being the hybrid cloud is the perfect solution for them. They are currently also using Arxus' private cloud. Resengo is now working on a new IT architecture to eventually transition completely to Microsoft Azure. Microsoft Azure can support Resengo's growth with modern applications which are often available by default. To take maximum advantage of the capabilities of Microsoft Azure, they will eventually transition entirely to the Microsoft cloud. Ultimately, today's transition is also less costly than using custom applications in the private cloud.
A good mission, a clear vision, and shared values can connect and motivate people to achieve a common goal. Arxus tries to reflect this as much as possible in their daily work. Arxus aims to increase productivity, efficiency, and innovation in companies by relieving them of managing IT business processes with their application-centric cloud solutions. They want to proactively analyze business processes and automatically adapt cloud solutions to meet the changing needs of businesses. This means: providing the best possible experience on any platform or device. Arxus aims for an environment in which everyone feels at home and where colleagues become friends. They celebrate accomplishments. Success equals enjoyment. Arxus never stops learning and does not shy away from challenges. Innovation is key. But to help any organization move to the cloud, they prefer a no-nonsense and local approach. Being close to customers and getting the job done as a team is of paramount importance. Where others are targeting the moon, Arxus is already on its way to Mars.
Resengo relies on the services of Arxus for everything that has to do with the underlying infrastructure. In terms of infrastructure, the collaboration with Arxus offers Resengo an essential advantage. Arxus can also make good use of the knowledge network of Cronos, of which Arxus is a part. The company can fully focus on its core activities: the development of new functionalities and applications and, of course, customer support. Arxus has taken responsibility for the entire infrastructure component. This ensures that Resengo does not need to invest in machines or in infrastructure knowledge. Arxus provides this expertise. At the same time, Arxus offers guarantees of availability, performance, and security that would not be immediately feasible for Resengo under its own management. In the current hunt for talent, IT employees are very difficult to find. And then again: infrastructure expertise is not part of Resengo's core business. It works much better and more efficiently for them to meet the need for scalability via Arxus.
With Arxus, Resengo has a unique point of contact for any IT issue. Arxus has easy access to the broad ICT expertise of the entire Cronos Group. Whatever the question, there is always an answer. This not only gives Resengo a sense of security, it is also very convenient that we have all the necessary expertise at our fingertips via Arxus. Arxus is a partner who continuously thinks along with us and is on a journey together with us.Dirk Gypen: (CEO) - Resengo
