D2C succeeded in getting a clearer picture inside their network with Deep Discovery Inspector. “Visualization of the network showed us a lot of suspicious email slipped through the spam filter,” says Mr. Nohira.
Deep Discovery Inspector, thanks to its integration with OfficeScan, detected information and D2C isolated suspicious devices. Suspicious files and URLs/IP addresses that were detected were handled manually – not processed or blocked. However, this recently changed. “Just after the WannaCry ransomware caused a global uproar, we saw a massive increase in suspicious email, sometimes a few hundred a day. We couldn’t keep up, so we made changes to ensure suspicious files, URLs, and IP addresses were automatically isolated, and got through it without damage,” says Nohira. There has been no impact on business through false detection and the operational load has decreased by half.
Also, by adopting Deep Discovery Inspector’s threat levels, D2C has a company-wide standard for situations requiring an urgent response, allowing anyone to respond appropriately. “Deep Discovery Inspector reports are really helpful. We can identify the kind of attack and if there is a risk of information leakage, so it’s easier to explain things to management,” says Suzuki.
