Why companies need FileWall for Microsoft 365 mail?
Over 94% of malware is delivered via email (source: Verizon business, 2019 Data Breach Investigations Report). In general, hackers hide malware in standard files such as PDFs and Office documents to transfer their malicious code and spread it as an epidemic. As new unknown malwares are released daily, they manage to bypass the standard security systems which use detection-based methods for anti-malware.
The problem with unknown malware hidden in files is that not always it’s delivered by suspicious sender but sometime can be sent by trusted sender (i.e. employee within the company) who somehow got an infected file and forward it innocently. In fact, 34% of cyber attacks involve internal actors within the organizations.
