Wisag

Wisag is a Frankfurt‑based company that provides facility management and industrial services. In addition to these core activities, it operates as a ground handling service provider for aviation clients. The firm’s headquarters are located in Germany, and it serves markets that require integrated support for buildings, industrial plants, and airport operations. Its service portfolio includes maintenance, cleaning, technical support, and logistics coordination. By combining facility management with ground handling, Wisag positions itself as a diversified service provider within the German industrial and aviation sectors.

The organization’s scale is reflected in the impact of a earlier cyber incident that disrupted payroll processing for approximately 55,000 employees. This figure indicates a substantial workforce employed across its various service lines. Despite the shutdown of IT systems during the 2023 attack, Wisag reported that core business activities continued uninterrupted. The company has described having contingency plans that allow it to shift operations to backup infrastructure when needed. Such resilience suggests a level of operational redundancy built into its service delivery model.

Wisag’s response to the cyberattacks highlights several distinguishing attributes. After the initial breach in 2022, the firm stated it had invested in cybersecurity improvements to strengthen its defenses. When confronted with the second attack in 2023, it immediately shut down all IT systems and initiated restoration efforts while expressing confidence in a swift recovery. The company publicly refused to engage in ransom negotiations and involved law‑enforcement authorities in both incidents. At the time of reporting, Wisag asserted there was no evidence of customer or internal data exfiltration from the compromised servers.
