Real cases. Anonymised, but not sugar-coated.
From retail chains and banks to industry and education - our solutions prove themselves wherever reliability, speed and professionalism are required.
Ransomware, no monitoring, full investigation
Several servers encrypted, logs deleted by the attacker, no SIEM, no EDR. From Windows artefacts alone, we reconstructed the complete attack timeline over roughly 48 hours.
The attack the dark web gave away
Internal documents surfaced on the dark web before the client noticed anything. We worked backwards: from the confirmed leak (2.72 GB) to the compromised endpoint.
Security at the interfaces
For a multi-app SaaS platform (HR and payroll data), we tested five applications plus the cloud, and specifically what no one finds when testing them in isolation: the trust relationships between the systems.
