CrowdSec Reviews & Product Details

CrowdSec is an open-source security stack that detects aggressive behaviors and prevents them from accessing your systems. Its user-friendly design and ease of integration into your current security infrastructure offer a low technical entry barrier and a high-security gain. Once an unwanted behavior is detected, it is automatically blocked. The aggressive IP, scenario triggered and the timestamp is sent for curation, to avoid poisoning & false positives. If verified, this IP is then redistributed to all CrowdSec users running the same scenario. By sharing the threat they faced, all users are protecting each other.

"very useful, well designed and efficient"

5/5

What do you like best about CrowdSec?

The best part is the capability to protect your infrastructure with a blocklist curated by the community. It runs really efficiently and has no problem to scale.

The monitoring of the alerts on the CrowdSec Console provides an integrated overview of the alerts on all your instances, in a very intuitive manner. When you have a doubt, you can also add comments, and find more about what the community tells about an IP address.

The system is really well designed Review collected by and hosted on G2.com.

What do you dislike about CrowdSec?

Nothing in particular, the tool is well designed... Maybe the work art around the alpaca is a bit too much Review collected by and hosted on G2.com.

"The missing component in the opensource security landscape"

5/5

What do you like best about CrowdSec?

Crowdsec is an excellent software that you can seamlessly install on thousands of servers in different environments. That's how easy it was to deploy in ours, thanks to the language behind Go.

It solved a major problem that our old IDS tools were suffering, false positives, dynamic updates, and above all: integration with our other tools.

Thanks to the recent API and existing integrations, we've been able to leverage all of Crowdsec features within our internal infrastructure Review collected by and hosted on G2.com.

What do you dislike about CrowdSec?

On the technical part, nothing is missing and the team is great for implementing features new customers require.

On the other hand, our organization is waiting for paid support, so we can leverage the knowledge of Crowdsec technical team and improve our business integrations. Review collected by and hosted on G2.com.

"Smart, efficient & crowd-powered cybersecurity protection for our servers"

5/5

What do you like best about CrowdSec?

As soon as we installed Crowdsec, we were able to monitor the constant sniffing and brute force attacks on our wordpress setup and admin page authentication. Once the wordpress bouncer installed, the suspicious IPs were presented with a captcha page or baned depending on the configured policy.

Crowdsec provided instant value and drastically reduced the suspicious activity on our servers.

Big up also to the crowdsourced IP database that allows to block IPs way before they start lurking around. Happy to be part of the IP crowd and even the balance in the fight against hackers. Review collected by and hosted on G2.com.

What do you dislike about CrowdSec?

Nothing specific, the product works & behaves as advertised. Review collected by and hosted on G2.com.

What problems is CrowdSec solving and how is that benefiting you?

Crowdsec helps us to mitigate and block the constant attacks that we have on our wordpress servers. Most attacks are automated scripts from script kiddies but one is never too careful and as our business is growing, it is essential to secure our activity and business as much as possible. Crowdsec acts as an early-detection and warning system, identifies all suspicious IP behaviors and blocks them according to predefined scenarios we created. The crowdsourced malicious IP database is also a considerable asset to ban poisonous IPs even before they start lurking around our servers. Review collected by and hosted on G2.com.

"Great approach to counter malevolent attacks using shared signals from the Internet Crowd"

4.5/5

What do you like best about CrowdSec?

The deployment of the product is seamless, it's 100% Free Software, and the community is welcoming and reactive Review collected by and hosted on G2.com.

What do you dislike about CrowdSec?

Not much, at the moment, the alerting and event decisions are polling-based. It could be more efficient to have an event-based mechanism to act after alerts are raised directly. Also, the documentation is lacking some details and could be improved. Review collected by and hosted on G2.com.
