Our latest statistics align with wider trends that show a steep rise in the number of cyberattacks being launched against business and organisations around the world, with DDoS and Ransomware the most prevalent methods of attack.

Craig Lusher, Senior Product Specialist – Secure, at Continent 8 Technologies, said: “We continue to see the number and scale of attacks rise each quarter. December was a particularly busy month for us, as expected due to the festive holidays, with hackers seeing this as a peak opportunity to launch cyber attacks.

“This year, quarter on quarter, we have seen record breaking DDoS attack numbers. In 1Q21 we saw 228 attacks, in the final quarter it’s up to 641, almost triple the amount. It’s evident that DDoS attacks are a huge threat to businesses of all sizes. Now is the time for organisations to establish efficient cybersecurity strategies, to defend themselves from this growing threat.”
