While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Company details

  1. Computer Security Service

Written by the company

CrowdSec is a participative, free, and open-source IPS. It detects unwanted behaviors in applications & systems logs and enforces remediation at any level (firewall, Rproxy, application, etc.) and of any sort (MFA, Captcha, Drop, …). The major strength of the product comes from its user network, where users share aggressive IP addresses that attack them. Combining both the behavior engine and this highly distributed network helps to provide actionable CTI.

Unwanted marketing call

Received an unsolicited CrowdSec sales call on 9 Oct 2025. No consent, no prior relationship. DPO contacted for clarification and erasure. Please stop cold-calling.

Reply from CrowdSec

A member of our team indeed contacted you through cold calling. After discussing it, I don't think he was aware that German legislation prohibits this form of contact. The issue has been addressed internally, and you won't be contacted again. As your contact was found in a usually credible database, Jack had no red flag when reaching out to you, and we are investigating how your number ended up in their tool.

We wanted to get in touch with you because 139 IP addresses coming from IP ranges your hosting company handles are reported in our database.

Excellent

Excellent, a brilliant concept and very flexible. The Hub with the Scenarios and Collections is great along with the powerful Community shared IP block list. Highly recommended.
