But an EDR alone, whether Microsoft, CrowdStrike or SentinelOne, is almost useless without 24/7 human supervision (MDR/SOC).

Discover the little-known functionalities that lie dormant in your subscription, and how to avoid paying twice for the same services.

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.

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.

Your Windows workstations leave the factory with 200 active services, vulnerable SMBv1, and identical admin passwords everywhere.

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.
