Our mission is clear.

Helping teams stay ahead of mass exploits and scans.

We tackle mass scans and exploits, silent enemies that quietly drain resources. Some lead to real attacks, others flood your systems with noise, overwhelming teams and tools. We know the enemy and help you stop losses before they happen.

We operate beyond the limits of traditional cyber deception.

ELLIO Research Lab operates its own independent deception network of high-interaction and adaptive sensors and honeypots - continuously evolving and strategically deployed. With multi-layered architecture, real-time data processing, and unique ML, it detects and misleads attackers at scale - uncovering mass exploitation, recon activity, and new threats as they happen.

High-quality threat data repository and CTI on mass exploitation and recon.

Pure, reliable data.
No third-party contamination.

Advanced research of patterns, anomalies, hidden connections.

Great news! We debut new defense tool at Black Hat 2025.

TCP Fingerprint Firewall.
New open-source recon shield.

At Black Hat USA 2025, ELLIO will unveil TCP Fingerprint Firewall - an open-source, high-performance eBPF-based firewall that detects and blocks malicious scanners through advanced TCP fingerprinting. Powered by MuonFP and built as an XDP module for ultra-fast packet filtering, it identifies tools such as Nmap, ZMap, and Masscan by analyzing their unique TCP behaviors rather than relying on the legacy rules of traditional firewalls.

Our Story

Inspired by the legacy of the first antivirus pioneers.

ELLIO started with Vlad Iliushin and Jana Tom, who first met at Avast, the antivirus company behind the first AV for Windows 95. In 2023, they launched ELLIO, a research lab focused on analyzing mass exploitation and recon, with a clear mission: to empower security teams through efficient automation and clear visibility into large-scale threats.

Our Headquarters

Based in Prague, where the Robot was born.

Our headquarters is in Prague, one of the best places to live in Europe. It’s also where the word “robot” was first used by writer Karel Capek in his 1920 play R.U.R. That idea helped kick off the world of automation and AI, which are now a big part of cybersecurity. We’re proud to call this amazing city our home.

Different backgrounds. One shared mission.

Vlad Iliushin

Vlad is a cybersecurity expert with a strong background in network security, IoT, and cyber deception. Before co-founding ELLIO, he led the Avast IoT Lab (now Gen Digital), focusing on security and IoT threats. Vlad also plays an active role in shaping cybersecurity testing standards as the President of AMTSO (Anti-Malware Testing Standards Organization). He's deeply committed to making cybersecurity efficient through effective automation and optimized resource management.
