Protect Yourself From DDoS Attacks

Based on current data, there is a rise in both the frequency and volume of attacks, including the attack durations. Ransom DDoS attacks are also rising, with the BFSI sector being the top targeted industry globally. Additionally, it has become cheaper for attackers and attackers-for-hire to launch DDoS attacks. 

Undoubtedly, this trend of large-scale DDoS attacks will not slow down.

Now more than ever, it’s crucial that you have a solid security plan to protect and secure all your digital assets.

While humans initiate DDoS attacks, bots execute them. You must automate detection and mitigation efforts as much as possible to win, which means relying on services such as Cloudflare.
