Welcome on-board Astra! Just after you add your website’s URL in Astra’s dashboard you’ll immediately see notification of two attacks on the URL you added. Please note that they are not real attacks but demo inserts to give you a feel of Astra’s dashboard & give a walkthrough through userguiding (a tool we use to give you automatic dashboard walkthrough). Further, after you’ve successfully installed Astra you can test all is working fine on your dashboard (trust IPs/block parameters etc) using these demo attacks.
So, nothing to worry about you’re all good with Astra 🙂
