Sausalito, Calif. – Apr. 8, 2021

The cybersecurity market in the Asia-Pac region is expected to grow by 15 percent year-over-year through 2025, fueled largely by a surge in cybercrime. 

“With billions of citizens and a significant share of the world’s economic activity, the Asia-Pacific region is a hotbed of innovation,” according to David Braue, an editor-at-large for Cybercrime Magazine. “Yet for all its benefits, that high-growth, fast-paced business activity has put the region’s companies on the front line of cybersecurity compromise this year as a ransomware explosion compounds the already significant baseline of cyber compromise,” adds Braue.

Fully 81 percent of companies in a recent study from Japan-based Trend Micro said they had suffered a cyberattack during 2020 — with 18 percent hit seven or more times throughout the year and 76 percent expecting that they will be hit by a cyberattack this year.

The robust economies of financial centers like Hong Kong, Singapore, Sydney and Tokyo have made them particular targets for financially motivated cybercriminal campaigns, with “double-extortion” ransomware — in which criminals not only lock data and demand a ransom for its release but also exfiltrate data and threaten to publish it on the dark web if the ransom isn’t paid.

KnowBe4 is one of the fastest-growing cybersecurity companies with a presence in Japan. While the security awareness training and phishing simulation high flyer is focused on educating employees in order to extinguish the greatest cyber threat — phishing attacks — the region features a lineup of some other impressive cyber defenders.
