Blocking Unwanted IPs vs. Blocking Unwanted Behaviors

Blocking any and all aggressive IPs is a solid option. But blocking IPs based on unwanted behaviors that have the potential to harm your infrastructure, gives you greater flexibility and targeted protection for your perimeter.

WordPress Blocklist

Contains IPs known for attacking WordPress environments. If you are using WordPress for your business or eCommerce website (WooCommerce), it is a safe bet that proactively blocking these IPs will save you from a lot of trouble.

Botnet/DDoS Blocklist

Contains IPs that have been identified as being part of a botnet, often seen in mass- scale attacks, such as Distributed Denial of Service. Proactively block these IPs for an overall safer perimeter.
