No empty promises: How we stopped acute IT disasters, passed enterprise audits, and saved companies from existential downtime.
Ransomware Defense & Clean Rebuild
Over 20 years of legacy IT infrastructure without standardized documentation. Following a heavy ransomware attack, all operations came to a halt for a full week; existing backups were compromised.
Full clean rebuild of the entire infrastructure within 48 hours. Comprehensive rollout of VLAN segmentation, Zero-Trust access policies, and a hardened immutable backup architecture adhering to BSI-Grundschutz standards.
0 minutes of unplanned downtime over the last 48 months. Recovery Time Objective (RTO) reduced from several days to under 45 minutes.
Secure Dev & Hosting Architecture
Strict compliance and security regulations combined with the need for agile, high-performance internal development and hosting infrastructures for the dev division.
Architecture, rollout, and operation of an isolated, hardened server and network environment built on GDPR-compliant open-source components (FOSS) and automated management.
100% audit and GDPR compliance alongside a 40% reduction in ongoing operational expenses compared to proprietary commercial cloud offerings.
Cluster Rescue Following Total Outage
Complete operational standstill: Outdated, failing vSphere/storage cluster, zero system access, customer passwords inaccessible, ordering/shipping stopped, staff sent home, backup NAS defective.
24/7 round-the-clock emergency response: SOS recovery of the entire 3-server cluster and 30+ virtual machines. Systematic step-by-step restoration of all core business processes within 10 days, followed by full system hardening.
€30M+ business operations saved. Full productivity restored after 2 weeks. Minimal data loss (only 1 test VM, immediately recreated). Environment running completely green, stable, and faster than ever before.
