Preventing bulk form submissions in Power Automate

(0) ShareShare

Posted on by Community Power Pla... Microsoft Employee

G'Day PA Community,

 

I'm hoping someone out there has thought of a way to prevent a malicious 'bulk submission' (like a DOS attack or similar) into a public MS Form trigger in Power Automate.

 

My flow is triggered when a (public) form is submittes, and I'm hoping there might be a way to use a trigger condition or similar to throttle high volumes of submission, using the time since last submission or something similar.

 

Since we cant implement reCAPTCHA or similar into Forms, I'm open to suggestions 🙂

 

Many thanks in advance!

    Hmm, I think if it's open, that's it. 

    The best I can figure, if it's triggering a Power Automate flow, you could make a condition at the beginning to turn off the flow for 5m or something if you get 3+ in the span of a minute, or something like that.

    There's nothing in the MS admin area that will help... all pointed at phishing rather than attacks...
