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. * * * Seller [CrowdSec](https://www.g2.com/sellers/crowdsec) Discussions [CrowdSec Community](https://www.g2.com/products/crowdsec/discuss) Languages Supported English, French Solution Type All-in-One Overview by Jean Devaux Show More ## Value at a Glance Averages based on real user reviews. ### Time to Implement \<1 month ### Return on Investment 7 months [ View More Pricing Information ](https://www.g2.com/products/crowdsec/pricing) ## Top-Rated Alternatives [ ![CrowdStrike Falcon Endpoint Protection Platform](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "CrowdStrike Falcon Endpoint Protection Platform") CrowdStrike Falcon Endpoint Protection Platform 4.6/5(441) ](https://www.g2.com/products/crowdstrike-falcon-endpoint-protection-platform/reviews) [ ![Netgate pfSense](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Netgate pfSense") Netgate pfSense 4.7/5(326) ](https://www.g2.com/products/netgate-pfsense/reviews) [ ![Sophos Endpoint](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Sophos Endpoint") Sophos Endpoint 4.7/5(837) ](https://www.g2.com/products/sophos-endpoint/reviews) [ View All Alternatives ](https://www.g2.com/products/crowdsec/competitors/alternatives) ## User Insights Average based on 88 real user reviews.

DevOps engineer Small-Business (50 or fewer emp.) 3/6/2023 "Has a steep learning curve, imo" 3.5/5 What do you like best about CrowdSec? I've been doing Linux administration and cybersecurity for more than twenty years. I found moving from Fail2Ban to CrowdSec came with a fairly steep learning curve, in my opinion. It lacks a lot of common plugin modules and writing your own requires a lot of moving parts and a new quirky language. For example, OpenVPN is an extraordinarily popular software yet no pre built collection, configuration or bouncer exists for it. I found it was not particularly easy/quick to implement a CrowdSec policy for guarding my OpenVPN ports, unlike with Fail2Ban which can whip up a rule quite quickly and with less files. I dont think the CrowdSec technical documentation is particularly well fleshed out nor easy to follow in comparison with other open source projects across the space. Review collected by and hosted on G2.com. What do you dislike about CrowdSec? Not super user friendly to use and implement custom policies for protecting services that do not have a collection, configuration or bouncer available on the CrowdSec Hub Review collected by and hosted on G2.com. What problems is CrowdSec solving and how is that benefiting you? It is helping to keep my machine more secure by filtering out pre identified malicious IP addresses. It also works in real time to detect and block active attacks. Review collected by and hosted on G2.com.

Small-Business (50 or fewer emp.) 6/6/2023 "Easy to use for private and enterprise-users" 4/5 What do you like best about CrowdSec? It is easy to use and there are already many extensions for the most popular software products. Crowdsec is at home on all the latest operating systems, which makes it easy to manage. And its open source! Review collected by and hosted on G2.com. What do you dislike about CrowdSec? Everything is in English, there is no German. Only the most popular products are supported directly. For special programs, you have to become active yourself to fill CrowdSec with data. The free plan for private persons is already limited and the paid plans are too expensive. Review collected by and hosted on G2.com. What problems is CrowdSec solving and how is that benefiting you? Securing my private servers from the evil internet. This is very easy to do and provides simple insight into who I am currently being attacked by. This way I can protect myself more effectively. Review collected by and hosted on G2.com.

Software and network engineer Small-Business (50 or fewer emp.) 8/11/2021 "The fail2ban on steroids that the infosec community was awaiting for in 2021" 4/5 What do you like best about CrowdSec? It is written in Go, meaning it is really fast and can be deployed everywhere without having to install dependencies which could be hacked to craft a supply chain attack. By having a single binary we can check signature easily. A detection can happens on a single machine and all the other machines that have a direct or indirect contact with that machine being under attack can take decisions as well. We have thus some kind of propagation of decisions which is quite welcome in this regard. If some people are willing to induce false positive results into the IP database, there is a consensus chamber and a system of ranking allowing to avoid this as well. By default, with the community plan, everyone is participating in the IP reputation. An attack being avoided at some location can help another user from another country. We clearly see the team has been tinking to the problem in a wholistic manner. On the ecosystem side, we clearly see we won't have any risk of abandonware as the business model is allowing to make the product sustainable without restraining the community. Corporate envs can buy the ability to monitor a huge amount of Crowsec agents, have a SaaS offer and also have the ability to keep their IP reputation private. Plus the team is super great to discuss with and easily reachable via a chat system, like we used to use in 2021. Review collected by and hosted on G2.com. What do you dislike about CrowdSec? While Crowsec is working in IPv6 environments, the IPv6 and IPv6-only environments have not been widely tested, but it is a matter of time before this happens and the docs are updated. Review collected by and hosted on G2.com. What problems is CrowdSec solving and how is that benefiting you? When an attack has been blocked on one machine, we can preventively block that attack on all the other machines as well. Having the ability to extend the filters to our needs is a big plus, meaning is a filter is not available, we can write/extend our own. Review collected by and hosted on G2.com.

Crowdsec is best suit to run seamlessly on virtual machines, bare-metal servers, containers or can be called directly from your code through API. It is an open-source end-point detection and response software. Review collected by and hosted on G2.com. What do you dislike about CrowdSec? Although being a good product, it is lessly marketed. It needs to be more brought to the open source market. There are more similar products which are given more push.. Also crowdsec currently cannot be put on all kinds of IT hardware. Review collected by and hosted on G2.com. Recommendations to others considering CrowdSec: This product is highly recommended considering its features and ease of use. It also open-source and gives lot of advantages when working with APIs. Review collected by and hosted on G2.com. What problems is CrowdSec solving and how is that benefiting you? Crowdsec provides open-source, free, security engine which helps to block and detect attacks depending on security logs. Crowdsec then shares the address details (IP address details) to the larger community. It can be put on web servers which are frequently exposed to frequent DDOS attacks, etc. Easy usage - It can be deployed and alerts can be monitored from a single console Review collected by and hosted on G2.com.
