This case study is an anonymized scenario built from real experiences shared by Kalkhan Security customers.
A manufacturing SME in Istanbul with 85 employees faced a ransomware infection after an employee opened a malicious email attachment. Its existing antivirus solution detected the threat too late, and an encryption attempt had already begun on the production planning server.
Project Overview
The goal was a rapid rollout of the Kalkhan Anti-Ransomware and Anti-Virus packages: stop the spread, isolate the affected endpoints and restore business continuity within 48 hours.
The Kalkhan support team broke the threat chain through remote response, and the behavioral analysis module blocked the encryption attempt.
- Kalkhan Anti-Ransomware deployed to 42 Windows endpoints
- Real-time file protection and a backup policy put in place
- Phishing awareness training delivered to staff
- Production server restored from backup with no data loss
Challenges and Solutions
The company's limited IT resources and ageing antivirus infrastructure had left the door open for the attack to spread quickly. Every hour of halted production carried a heavy cost.
Project Challenges:
A threat caught too late, a scattered backup policy and a lack of security awareness among staff added up to critical risk.
Risk of Rapid Spread
There was a strong chance of the ransomware reaching other workstations through network shares.
Business Continuity Pressure
Every day the production line stood still meant a direct operational loss.
Project Solutions:
Behavioral protection with Kalkhan Anti-Ransomware, a full system scan with Anti-Virus and a central management console were put in place.

Frequently Asked Questions
Affected endpoints are isolated first, then malicious processes are quarantined and the recovery steps are planned.
The Kalkhan agent runs on a lightweight architecture, and scan policies can be scheduled around working hours.
