Multicloud: Strategy of the Future or Costly Complexity Trap?

Multicloud - AWS + Azure + GCP - is sold as the ultimate freedom: avoid vendor lock-in, negotiate prices, choose the best of each cloud. The reality: 78% of multicloud companies blow their budget by +30%, you're not free of 3 suppliers but locked into three, and your €157k/year in extra costs (data transfers, tools, salaries) are used to protect you from a migration risk you'll never take. We take a look at why 95% of companies would be better off sticking to a single cloud, and the 5% where multi-cloud really makes sense.

Microsoft Sentinel: The Cloud SIEM that Costs a Fortune if You Don't Control Ingestion

Sentinel can save you €1.95M by detecting ransomware in 8 minutes instead of 2 days, or ruin you with €53,820/month of useless debug logs that nobody looks at. Between the two, there's an ingestion strategy that 80% of companies miss: they activate all the connectors "just to see", and 3 months later they're paying 800GB/day including 650GB of worthless noise. We show you how to go from 66k€/month to 662€/month (97% savings) without losing detection capacity, and above all how to know if you really need a SIEM.

Workstation Hardening: The Pragmatic Guide to Securing Windows Without Paralyzing Production

Your Windows workstations leave the factory with 200 active services, vulnerable SMBv1, and identical admin passwords everywhere. It takes ransomware 2 hours to encrypt your entire domain, but applying 847 CIS settings manually would take you 6 months. Here are the 15 real priorities that deploy in 2 weeks and block 80% of real attacks.

Azure Bastion: Secure RDP/SSH access without exposing your VMs (and without blowing your budget)

140/month to avoid exposing your VMs to the Internet with a €4 public IP, that's Azure Bastion. The pitch: one-click security without network expertise. The reality: a service that can be indispensable for your production or a total waste if you're protecting 2 dev VMs used 3 hours a week. We take a look at when Bastion is really worth the money, when it'll ruin you for nothing, and at the cheaper alternatives that nobody explains.

Microsoft Copilot: Artificial Intelligence that Really Transforms Business Productivity (or Not)

Copilot at €30/month per head: strategic investment or €100k wasted on a tool that nobody uses? 70% of IT Departments buy without defined use cases, train their teams poorly, and discover 6 months later that a third of the licenses are never activated. We tell you how to calculate whether it's worth it BEFORE you sign, and which 5 use cases really pay off.

Microsoft Purview: The Complete Data Governance Solution for the Multicloud Era

Your teams spend 60% of their time looking for the right data, your CIO doesn't know where customer information is stored, and the next RGPD audit has you sweating. Microsoft Purview promises to solve these problems by unifying cataloging, security and compliance in a single platform. But is this really the silver bullet for your context, or a vendor lock-in trap in disguise?

Phishing in 2025: Why 82% of businesses will be phished this year (and how to avoid being phished)

Think your employees will never click on a phishing scam because you've "trained" them? 32% will click anyway, and this figure rises to 45% under stress or at the end of the day. Attackers no longer make spelling mistakes, they have your logo, your graphic charter, and information about your actual projects. A single click = €275k in average costs, 287 days to recover if it's ransomware, and 60% of SMEs affected close down within 6 months. We explain why blaming users is absurd, and which technical protections really work.
