We turn crowd-powered intelligence into actionable blocklists to maximize the efficiency of your security operations and reduce your costs
Be Proactive & Minimize Downtime
Proactively block known malicious IPs to avoid service downtime and potential data losses that can lead to a significant loss in revenue and customer trust, as well as regulatory fines.
Reduce Server Load & Egress Costs
Proactively block offensive IP addresses and make sure your servers dedicate all their resources to serving customers rather than attackers.
Optimize Incident Response Costs
Filter out background noise to reduce the number of security alerts at the SOC level by 80% and allow your security experts to focus on critical security events.
Unmatched Data Curation
Get more than just a list of unwanted IPs
We ultra-curate our data to provide you with detailed context on the behavior of aggressive IPs and build curated lists — DDoS, botnets, VPNs, residential proxies, and more — to equip you with the intelligence you need to safeguard your services.
We Collect Real-Life Data
While blocklists are typically built on data collected from honeypots or data scraped from not-so-reliable third-party sources, our data comes from real users, real servers, in real production environments.
We Invest in Data Diversity
Nothing better guarantees data quality than data diversity. The growing CrowdSec Network consists of 70,000+ active users in more than 190 countries around the world, sharing an average of 10 million signals on aggressive IPs daily.
We Safeguard Quality
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.
We Guarantee Top-Priority Updates
Honeypots and third-party blocklists provide insufficient updates, resulting in cleared IPs remaining on blocklists and new infections taking longer to be added. You won’t get any of that here. CrowdSec Blocklists offer an average of 5% daily rotation of IPs.
Plug n’ Play With Immediate Benefits
Integrating the CrowdSec Blocklists into your infrastructure is simple, effortless, and fail-proof.
2. Implement the Blocklists as automated blocking rules on your existing firewall or CDN
3. Enjoy an immediate reduction in security alerts and a decrease in operational costs
Explore the CrowdSec Ecosystem
We take data quality very seriously and nothing speaks of higher data quality than data diversity. That is why we are making sure we can collect data from a great variety of sources. The CrowdSec Security Engine, CrowdSec’s open-source software, sits at the heart of our data collection process.
The Security Engine is OS and infrastructure-agnostic and integrates with many popular tools with the CrowdSec ecosystem constantly expanding.
More integrations mean more signals on aggressive IPs generated. The higher the number of signals generated, the higher the data quality.
