10 Top DNS attacks

During recent days, DNS based attacks are on the rise

So, they are vulnerable to DNS based DDoS Attacks such as amplification, reflection, etc. Since they require high compute performance which is costlier to accurately detect DNS-based attacks, Traditional Protection is ineffective.

If DNS Service goes down, network attached devices stop working. For Companies, this kind of DNS vulnerabilities leads to loss of revenue, customer defection and negative brand impact.
