Cisco Adaptive Security Appliance (ASA) Software vs. CrowdSec

Cisco ASA's are great for internal network connected access between a firewall and the central management server. And, for complex networks where high security requirements with overly strict compliance are necessary. For networks with limited connectivity to the core or for poor network connectivity these are not the best solution. There are other more stand-alone firewall's that do this better. These firewall's are a little more complex to set up to start with so significant knowledge of these devices is required to set them up and ensure they are best practice installed.

Since I've only used CrowdSec in a homelab/small-medium sized business setup, that's really the only market I can safely recommend it and say it's well suited for, because I don't know how much it would cost to run it in an enterprise environment. I've heard some pricing and how they plan on rolling out a subscription model, but it's still in talks. Either way, if you have publicly exposed web applications hosted locally or on a virtual private server, then CrowdSec should be part of every virtual machine and/or network. Even with the lmited number of filter you get out of the free subscription, it provides a nice layer of constantly updated data,

• ASA is our VPN concentrator. The client and server are very stable and very easy to use
• ASA also offers Intrusion Prevention, to an extent. This is also very useful for an improved security posture for a small company
• ASA allowed us to scale very quickly. We could onboard clients, partners, and consultants and give them a great onboarding experience as well
• Administrative costs with ASA are low. It's very easy to administer.

• Provides great integrations with tools you already use, such as fail2ban, Cloudflare, WordPress, NGINX, Linux Firewalls, etc.
• Lightweight agents can run on individual servers and report to a main security engine so that if there's an attack on one server and a block is implemented, the entire network can be protected
• There are a lot of ways to receive alerts and store logs
• CrowdSec Central API is a nice way to manage everything externally

• The ASDM software is at times a nightmare to install because of different java versions[.]
• [The firewall] could do with a power button, just to be able to do a hard reboot when needed[.]
• It would be nice to manage the firewall via the web on port 443[.]

• Getting CrowdSec to run on OPNsense can be a challenge, but that's also a limitation of the OS
• You can only subscribe to a couple of feeds before paying an unknown amount of money that's part of their "Enterprise" package. So, there could be better transparency.

To be honest there has been now great products out in the market compared to Cisco ASA. I beleieve Cisco has to do a lot of improvement in this area. The other defeiniete factors is the cost when it comes to renewals which is always a premium on Cisco products

I generally have not noticed the outages, however since it's a machine it can malfunction, we need to implement the firewall infrastructure in such a way that it is highly available with device failure, region failure etc. Else any solution will be having the issues if they are not build with resiliency.

The support is usually very good and gets back to you very quickly. However I had some instances of when two engineers will give me wildly different answers to what I thought was a simple question. Overall however I do rate the support highly and they are generally always very good.

It was quite a good one, how ever requires an expertise to deploy hence the SMB segment would be finding it difficult to implement this product. The one good reason is that there are lot of ASA certified engineers in compared to the other certified engineers. Hence this resembles positively on the deployment as you have quite a lot of experienced engineer on your deployment

We were using [pfSense] before in our environment but we regularly facing difficulties over it due to software bugs & downtime. After implementing Cisco ASA, it resolved our availability issue & provides us a reliable solution with the best security features & easy to understand GUI.

• Most network engineers have worked with ASA, so there is no need for re-training when adding or turning over staff
• Current configs from older devices plug in easily, and are operational on larger devices if an upgrade is required
• Many support options available

• It flat-out blocks malicious IPs from accessing any PC on my network.
• It's free-tier makes this a no brainer to implement
