CrowdSec is an open-source, crowd-sourced security engine. It deploys agents on your servers that detect attacks, share signals with the CrowdSec network, and can pull community blocklists. ThreatListPro is a managed, curated VPN-specific blocklist delivered as a single External Dynamic List (EDL) URL. CrowdSec requires installing and maintaining agents (called "bouncers") on every system you want to protect. ThreatListPro requires pasting one URL into your firewall. This comparison helps you decide which model fits your environment.
ThreatListPro and CrowdSec take fundamentally different approaches to threat protection. ThreatListPro is a narrowly focused, manually curated blocklist built from VPN honeypot data and delivered as a single URL. CrowdSec is a distributed platform that deploys agents across your infrastructure to detect, share, and remediate threats in real time. Understanding this architectural difference is the key to choosing the right tool.
Quick Comparison
| Feature | ThreatListPro | CrowdSec |
|---|---|---|
| Focus | VPN brute force specific | Broad (SSH, web, API, VPN) |
| Architecture | Managed EDL URL | Agent-based + central API |
| Intelligence | Curated from VPN honeypots | Crowd-sourced community signals |
| Setup | Paste URL into firewall, 5 min | Install agent, configure parsers/scenarios |
| Maintenance | Zero | Agent updates, parser maintenance |
| False Positives | Very low (manual curation) | Variable (community signals) |
| Firewall Integration | Native EDL support | Requires bouncer (agent) per device |
| Free Tier | 30-day trial | Free community edition |
| Pricing | $9.99/mo | Free (community) / $$ (premium blocklists) |
When to Choose ThreatListPro
ThreatListPro is built for one specific job: stopping VPN brute force attacks at the firewall perimeter. If any of the following describe your situation, it is the better choice.
- VPN brute force is your specific problem. You are seeing thousands of failed login attempts against GlobalProtect, SSL-VPN, AnyConnect, or another VPN portal. You need a list that targets exactly this attack vector, not a broad security engine that covers everything from SSH to web application attacks.
- You need immediate firewall-level protection. You want to block attackers before they reach your VPN portal, not detect and respond after the traffic hits your servers. ThreatListPro works at the firewall perimeter via EDL, blocking connections before they are established.
- You do not want to deploy agents. CrowdSec requires installing a bouncer on every system you want to protect. ThreatListPro requires pasting one URL into your firewall configuration. No software to install, no agents to update, no parsers to maintain.
- You are an MSP managing multiple client firewalls. A single EDL URL can be deployed across dozens of customer firewalls in minutes. Deploying and maintaining CrowdSec agents across multiple client environments is significantly more complex.
When CrowdSec Might Be Better
CrowdSec is a well-engineered open-source project with a large community. It is the right choice in certain scenarios.
- You need broad threat coverage beyond VPN. CrowdSec detects SSH brute force, web application attacks, API abuse, and many other threat types. If VPN brute force is just one of many attack vectors you need to address, CrowdSec's breadth is an advantage.
- You want to contribute to community intelligence. CrowdSec's model is built on sharing. Your agents detect attacks and report signals back to the network, which benefits all participants. If contributing to collective security is important to your organization, CrowdSec aligns with that philosophy.
- You already run CrowdSec agents. If your infrastructure already has CrowdSec deployed, adding VPN protection scenarios is incremental work. Deploying a separate blocklist service on top of an existing CrowdSec installation adds complexity without clear benefit.
- You need a free tier indefinitely. CrowdSec's community edition is genuinely free with no time limit. ThreatListPro offers a 30-day trial, then costs $9.99/month. If your budget is truly zero long-term, CrowdSec is the sustainable option.
Architecture Difference
The fundamental difference between ThreatListPro and CrowdSec is architectural. Understanding this difference explains most of the tradeoffs in the comparison table above.
ThreatListPro: One URL, Any Firewall
ThreatListPro delivers a plain-text IP list at a stable URL. Any firewall that supports External Dynamic Lists (EDLs) can consume it natively: Palo Alto, Fortinet, Cisco, SonicWall, pfSense, OPNsense, and others. There is nothing to install, no agents to deploy, and no infrastructure to maintain. Your firewall pulls the updated list on a schedule you configure.
CrowdSec: Agents on Every System
CrowdSec requires deploying an agent (called a "bouncer") on each system you want to protect. The agent reads logs, detects attack patterns using parsers and scenarios, reports signals to the CrowdSec API, and applies remediation decisions locally. For firewall integration, you need a bouncer that can communicate with your firewall's API. This is powerful but requires installation, configuration, and ongoing maintenance on every protected system.

# CrowdSec: install agent, configure, deploy bouncer per system
$ curl -s https://packagecloud.io/install/repositories/crowdsec/crowdsec/script.deb.sh | sudo bash
$ sudo apt install crowdsec
$ sudo apt install crowdsec-firewall-bouncer-iptables
$ sudo cscli scenarios install crowdsecurity/ssh-bf
$ sudo systemctl restart crowdsec
Can You Use Both?
Yes, and it is a strong combination. The two tools operate at different layers and complement each other well.
- ThreatListPro at the firewall perimeter. Block known VPN brute force attackers before their traffic reaches your network. This is your first line of defense, handled entirely by your firewall's EDL with zero agents deployed.
- CrowdSec agents on individual servers. Deploy CrowdSec bouncers on your internal servers (SSH hosts, web servers, application servers) for additional detection and response. CrowdSec catches threats that make it past your perimeter and handles attack vectors that ThreatListPro does not cover.
This layered approach gives you curated VPN-specific blocking at the edge and broad community-driven detection on internal hosts. The two systems do not conflict because they operate independently at different points in your network stack.
Frequently Asked Questions
Is CrowdSec a good alternative to ThreatListPro?
They are different models. CrowdSec is an agent-based security platform with broad coverage across SSH, web, API, and VPN threats. ThreatListPro is a managed blocklist focused specifically on VPN brute force with zero-agent deployment. If your primary concern is VPN brute force protection with no infrastructure to manage, ThreatListPro is the simpler choice. If you want a full security engine with community-driven intelligence across multiple attack vectors, CrowdSec offers more breadth.
Does CrowdSec work with firewalls like Palo Alto?
CrowdSec's firewall integration requires deploying a "bouncer" (agent) on or near each device you want to protect. This bouncer pulls decisions from the CrowdSec API and applies them locally. ThreatListPro works natively with any firewall's External Dynamic List (EDL) feature — no agents needed. You paste a URL into your firewall configuration and it pulls the blocklist automatically.
Which has better VPN brute force coverage?
ThreatListPro, because it is built specifically from VPN honeypot data targeting GlobalProtect, SSL-VPN, and AnyConnect attacks. Every IP on the list was observed actively brute-forcing a VPN portal. CrowdSec's community signals are broader but less VPN-specific — its strength is breadth across many attack types rather than depth in one.
