Not Just Another Blocklist

  • Overblocking IPs?

    Honeypots and third-party blocklists provide insufficient updates, resulting in cleared IPs remaining on blocklists and new infections taking longer to be added.

    With a 5% daily rotation on average, you won’t get any of that with CrowdSec.

  • High False Positives?

    We shield our data against false positives and poisoning using a combination of methods, including:

    • Reporter trust score and diversity
    • Machine profiling
    • Cross-checking data sources to guarantee information consistency
    • and more…
  • No VPN/Residential Proxy Detection?

    An efficient blocklist offers more than just a list of unwanted IPs.

    We employ behavior analysis on the data collected from the CrowdSec Network to provide you with ultra-curated lists — DDoS, botnets, VPNs, residential proxies, and more — to equip you with the intelligence you need to safeguard your services.

  • Infrequent Updates?

    CrowdSec Blocklists offer an average of 5% daily rotation of IPs.

    They are updated in real time and at top priority, providing you with fresh and relevant data daily and ensuring that the list of IPs you feed to your firewall is never out of date.

Blocking Unwanted IPs VS.Blocking Unwanted Behaviors

Blocking any and all aggressive IPs is a solid option. But blocking IPs based on unwanted behaviors that have the potential to harm your infrastructure, gives you greater flexibility and targeted protection for your perimeter.

Explore the crowd-powered and ultra-curated CrowdSec Blocklists

CrowdSec Intelligence Blocklist

Contains all IPs in our database that have been identified as actively aggressive, performing a wide variety of attacks. Proactively block these IPs if you don’t want to take any chances with malicious IPs potentially reaching your systems.

Industry and Service-Focused Attackers Blocklists

Contain IPs frequently attacking organizations in a specific sector. We currently cover Banking & Insurance, Healthcare, Hosting, MSSPs, Retail & Ecommerce, IT & Services. Block these IPs to reduce security alerts and establish a safer perimeter to protect critical systems.

Country-Focused Attackers Blocklists

Contain a CrowdSec-aggregated list of the most aggressive IPs specifically targeting entities in a specific country. Proactively block these IPs to reduce the volume of your security alerts and establish an overall safer perimeter.

High Background Noise Blocklist

Contains IPs identified as malicious or potential threats performing mass exploitation attempts contributing to your internet background noise and high volume of security alerts. Blocking these IPs can reduce your alert volume and save infrastructure resources.

HTTP Attackers Blocklists

Contain IPs that have been mainly reported for performing HTTP DoS attacks or HTTP exploitation attempts. Proactively block these IPs to prevent DoS and HTTP exploitation attempts on your systems and establish an overall safer perimeter.

Custom Blocklists

Do you need custom blocklists for specific use cases? We work with you to make sure you have the intelligence you need to safeguard your services.
