Moving Legacy Systems to the Cloud Efficiently : Balancing cost, risk, and continuity in complex migrations

Migrating legacy systems to the cloud remains one of the toughest balancing acts in IT. Every choice affects stability, cost, and trust at once, and what starts as a modernisation effort quickly turns into a negotiation between ambition and reality. Suddenly budgets rise, dependencies appear late, and timelines tighten as old architectures collide with new expectations. In the end, success depends on sequencing, ownership, and aligning business priorities with infrastructure limits, and not only on technical readiness. Making it work requires more than a plan on paper. Knowing which systems genuinely belong in the cloud, which can wait, and which should stay put shapes the entire roadmap and defines its success. Each refactoring decision sets the level of future flexibility, but it also drives cost and risk. The trade-offs between speed, sustainability, and resilience only become clear once migration begins and pressure builds. Let’s discuss how to plan migrations that stay on track, manage hidden dependencies, and handle downtime with confidence. Let’s also discuss how governance, testing, and vendor coordination keep progress visible and credible. Are you in? A closed conversation for those who turn cloud migration from a disruption into a long-term advantage.

The CIO as Investor - CIONET Belgium Annual Event

CIOs today are being judged less as technology leaders and more as portfolio managers. Every euro is under scrutiny. Boards and CFOs demand lower run costs, higher efficiency, and clear ROI from every digital initiative. Yet, they also expect CIOs to place bets on disruptive technologies that will keep the enterprise competitive in five years. This constant tension is redefining the role. In this session, we go beyond FinOps and cost reporting to tackle the strategic financial dilemmas CIOs face.

AI-Driven Development: Redesigning workflows, responsibilities, and trust in the age of automation

AI coding assistants entered development teams quietly, but their impact grows by the day. What started as autocomplete now shapes architecture decisions, documentation, and testing. And when productivity gains are visible, so are new risks: security blind spots, uneven quality, and the slow erosion of shared standards. Teams move faster, but not always in the same direction. The challenge has become integration rather than adoption. And new questions have risen: how do you blend automation into established practices without losing oversight? When is human review still essential, and what should the rules of collaboration between developer and machine look like? As AI tools learn from proprietary code, where do responsibility and accountability sit? Let’s talk about how to redefine those workflows, balancing creativity with control, and protecting code quality in a hybrid human-AI environment. A closed conversation on where AI accelerates progress, where it introduces new debt, and how development culture must evolve to stay credible.

Zero Trust in Reality : Making segmentation, identity, and access work in complex environments

Zero Trust sounds simple on paper: trust no one, verify everything. But once you start implementing it, the fun begins. Legacy systems, hybrid networks, and human habits don’t read the manual. The idea is solid; the execution, not so much.

University of Warwick bolsters cyber defences with Trend Micro Cloud App Security

Bolsters cyber defences with Trend Micro Cloud App Security

OVERVIEW

The UK education sector is an increasingly popular target for cybercriminals. Separate pieces of research have revealed that many universities have faced phishing and ransomware attacks. Given the highly sensitive research-based IP and personal data on students and staff stored by these institutions, it’s no surprise that they’ve become a favourite of hackers.

The University of Warwick has recognized the rise in attacks and proactively decided to further strengthen its defenses. Its Head of Cloud Services, Des Butcher, in conjunction with colleagues, sought out third-party expertise to help secure its Office 365 environment.

RISING THREAT LEVELS

The University’s existing anti-spam and malware capabilities were based on existing Unix relays; an unsustainable situation given the rapidly increasing volume, complexity and variety of threats. Des and his colleagues in ITS therefore set out to find a more effective solution to the problem; and one which addressed not only the primary threat vector of email but also provided protection across the entire Office 365 range. A priority was placed on third-party providers who could offer tight integration with Microsoft’s online productivity suite with an easy-to-implement product set.

ENTER CLOUD APP SECURITY

Des started a review of security solutions in January 2017, and asked a select group of vendors to present to the email team and IT security staff. Trend Micro™ Cloud App Security was chosen based on this presentation, and some outstanding commercials.

Trend Micro Cloud App Security is the perfect choice for businesses looking to extend the built-in security protections of Office 365 with advanced malware detection and data loss prevention. Here are just some of the benefits:

Document exploit detection helps find malware including ransomware in Office formats like Word, PowerPoint, and Excel.

Trend Micro™ Deep Discovery™ sandbox technology detects unknown malware and shares intelligence with other security layers.

Trend Micro™ Smart Protection Network™-derived intelligence finds malicious URLs in both the message body and email attachments.

Detects attacks in progress as hackers try to migrate via email from compromised accounts within the organization.

Data Loss Prevention for OneDrive, SharePoint Online, Dropbox®, Box®, and Google Drive™ uses over 200 pre-built and customizable compliance templates to control sharing of controlled data.

Scans files shared from remote workers and partners.

Tight API-based integration means automatic, hassle-free set-up.

Trend Micro has been a Microsoft Gold Partner for 20 years.

"Trend Micro sits within your tenancy. That proximity to the data being protected had a significant advantage versus other gateway products. Typical gateway products focused on just email, rather than email, SharePoint and OneDrive, which are the other significant aspects of Office 365."

Des Butcher - Head of Cloud Services, University of Warwick

MAXIMUM SECURITY, MINIMUM OUTLAY

Des and his team first conducted some pen testing exercises on Cloud App Security before running the product in monitoring mode for a couple of weeks to check for false positives. The results were very good and the product was switched on.

It’s been plain sailing ever since: although the attacks keep on increasing, the impact on the university is significantly lower than that prior to Cloud App Security installation, says Des.

“We haven’t been affected by the majority of the attacks on higher education institutions that get reported” he adds.

The product has also helped Des save valuable resources, at a time when budgets are tight.

“By moving our defense into Office 365, we’re in a position to reduce the amount of resource we devote to this area and focus it elsewhere,” he concludes.

“From a commercial point-of-view, I’m confident its cost is neutral and has delivered significant benefits.”

"We can see a measurable benefit: a reduction in the volume of malware arriving in our users’ inboxes. We can look at the dashboard and get a view of potentially thousands of pieces of malicious content getting blocked."
