European Utility Giant: Eliminates File-borne Threats to Upload Portals with Menlo Security

As one of Europe’s most substantial utilities serving millions of customers across over a dozen countries, the company faced a significant vulnerability within its customer-facing web portals. To maintain operational efficiency, these portals allowed the submission of diverse documents—ranging from Excel sheets to images—creating a steady stream of data that exposed the organization to ransomware, rootkits, and zero-day threats undetectable by traditional antivirus solutions.
