WatchGuard's Internet Security Report is based on anonymised Firebox Feed data from nearly 30,000 active WatchGuard UTM appliances worldwide, which blocked more than 19 million malware variants and 1.6 million network attacks in Q3. The complete report includes defensive strategies for responding to the latest attack trends, based on analyses of the quarter's top malware and network threats. The report also examines the growing trend of supply chain attacks by evaluating the most notable instances from Q3 – NetSarang, Ccleaner and fake Python packages.
