Fail2Ban 2.0, but much better
What do you like best about the product?
CrowdSec is very powerful when you have only one machine to protect. But if you have to preserve much more devices in your infrastructure, the best feature is the ability to centralize the decisions, and thus, CrowdSec does native mitigation of the banned IPs. In addition, the scenarios system is easy to learn and strong.
What do you dislike about the product?
Nothing, really. This software does its work very well!
What problems is the product solving and how is that benefiting you?
CrowdSec was helpful against DoS and brute force attacks. The traffic was instantly impacted, just with half of our machines equipped.
Recommendations to others considering the product:
Do not hesitate to interact with the developers, they are very reactive on Gitter.

Excellent and seamless security solution
What do you like best about the product?
The open-source core makes it very transparent and secure: it does not entirely anchor you.
Modern and way more effective alternative to Fail2ban.

The fail2ban on steroids that the infosec community was awaiting for in 2021
What do you like best about the product?
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.

What do you dislike about the product?
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.
What problems is the product 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.
Modern take on blocking bad actors
What do you like best about the product?
Crowdsec makes it easy to block rogue IP addresses automatically based on a crowd-sourced database verus just blocking IPs that you detect like other solutions such as fail2ban. The advantage is the database is refreshed on current known rogue actor IPs. Crowdsec is easy to configure, and in my situation, it was easy to drop into my current setup.
What do you dislike about the product?
I haven't ran into an downsides to using Crowdsec.
What problems is the product solving and how is that benefiting you?
Crowdsec is currently being used to block bad actors from accessing my personal file sync server and VPN service. I've also recommended to clients that I work with to use Crowdsec for internet-facing applications.
Great approach to counter malevolent attacks using shared signals from the Internet Crowd
What do you like best about the product?
The deployment of the product is seamless, it's 100% Free Software, and the community is welcoming and reactive
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
We could counter a multitude of attacks at different levels of OSI stack (tcp, http, etc.) from changing and malevolent IPs. Unethical traffic is drastically reduced, reducing the total bandwidth waste on a network.
CrowdSec, the must-have security tool of the decade
What do you like best about the product?
CrowdSec is a really simple concept, implemented in a free/opensource software, that allows to you blocks potential attacks on your servers, or to mitigate actual attacks
What do you dislike about the product?
CrowdSec's internals might be a little bit complicated for regular IT users
What problems is the product solving and how is that benefiting you?
CrowdSec is like a giant shield that protects you from several types of attacks
