Adaptive IP blocking driven by early signals

ELLIO detects infrastructure involved in malicious activity, reconnaissance, and mass exploitation in real time, automatically enforcing blocking across your firewalls. Once activity stops, IPs are removed automatically, preventing overblocking and minimizing false positives.

Ultiimate IP BlockingFingerprint Firewall

Full control over scanner traffic without overblocking

Decide which scanners and services to block or always allow. ELLIO maintains a continuously updated database of scanner IPs as well as business and cloud service addresses, ensuring your firewall rules stay accurate as external infrastructure changes.

Recon IP ListsBlocklist Management

Automate blocking rules with confidence

Keep critical traffic flowing safely while preventing incidents and false positives. Manage all blocklists and custom IP rules across your firewalls from a single, centralized console without manual syncing, blind spots, or update delays.

FAQ

How is ELLIO different from traditional IP blocking?

ELLIO delivers dynamic, context-aware IP blocking powered by real-time reconnaissance and mass exploitation intelligence from its own advanced cyber deception network. Instead of relying on static reputation or known-bad lists, ELLIO identifies attacker infrastructure based on actual behavior and intent, before it is widely classified as malicious.

It is fully configurable, allowing you to avoid false positives and protect critical business traffic. Unlike traditional blocklists, ELLIO clearly distinguishes between benign crawlers and reconnaissance linked to active campaigns, enabling security teams to act earlier, prioritize real threats, and reduce risk across the network.

How is ELLIO different from CrowdSec, Spamhaus, and other IP blocklist providers?

 ELLIO builds its threat intelligence from a proprietary global cyber deception network, removing dependency on third-party data and eliminating risks like feed poisoning or stale data. It continuously correlates attacker behavior, reconnaissance patterns, and exploitation attempts, automatically updating and enforcing blocklists across firewalls in near real-time, well before signatures or static feeds can respond.

 

Unlike CrowdSec or Spamhaus, which provide reputation-based or community-shared lists, ELLIO delivers context-aware, high-frequency dynamic updates with automated enforcement. This approach reduces false positives, cuts operational overhead, and ensures security teams focus on real threats instead of chasing noise. ELLIO provides a proactive, precision-driven defense layer that traditional blocklists cannot match.

Does ELLIO integrate with existing firewalls?

Yes. ELLIO is integrated with major firewalls like Palo Alto Network, Check Point, Fortinet - FortiGate, Cisco, Sophos, F5, or ntopng. It’s also integrated with open source firewalls OPNsense, pfSense, and Traefik or Linux. Once you define block/allow rules, policies are automatically enforced across all your firewalls without manual syncing or vendor-specific configurations.

Can I configure ELLIO IP blocking according to my needs?

Yes. ELLIO IP Blocklists are fully configurable through ELLIO Blocklist Automation, giving security teams precise control over what is blocked and what must remain accessible across all managed firewalls. You can create custom blocklists per customer or environment, prioritize high-risk infrastructure tied to mass exploitation, and ensure trusted services - like SaaS platforms, partners, and approved scanners - are never disrupted. All policies are automatically enforced across your multi-vendor firewall environment, without manual overhead.

How does ELLIO affect false positives and SIEM noise?

ELLIO blocks only active malicious and high-risk IPs involved in active reconnaissance or mass exploitation, while ensuring critical business services, SaaS platforms, and essential bots always remain allowed.

Its fine-grained IP rules let you control exactly what gets blocked or allowed, preventing disruptions to core infrastructure. This approach drastically reduces false positives and unnecessary SIEM alerts, so security teams can focus on real threats instead of chasing noise.

How is ELLIO valuable for MSPs offering managed firewall services?

ELLIO extends managed firewall services with preemptive protection against reconnaissance and mass exploitation, going beyond what firewall vendors and static blocklists deliver. MSPs can automatically block attacker infrastructure before it turns into customer incidents, while ensuring critical business traffic is never disrupted.

Built as a multi-tenant platform, ELLIO allows MSPs to manage customizable blocklists per customer and enforce them consistently across multi-vendor firewall environments. This reduces operational overhead, lowers SIEM noise, and enables MSPs to deliver a scalable, intelligence-driven security service that clearly differentiates their offering.
