ELLIO at it-sa 2024: From Reconnaissance to Clean Alerts.

At it-sa 2024, ELLIO highlighted two key challenges: large-scale internet reconnaissance and the growing number of alerts in SIEM and SOAR systems, often generated by mass exploitation, automated bots, and opportunistic scanning.

The it-sa Expo & Congress, held every year in Nuremberg, Germany, is one of Europe’s top events for IT security, and ELLIO was excited to be there. it-sa 2024 was a fantastic success, not just because of the record number of visitors – 30.000 – but also for the three days filled with inspiring chats, new connections, and valuable insights into what IT and cybersecurity professionals need today.

Reconnaissance: The first stage of most cyberattacks

At it-sa 2024, ELLIO highlighted reconnaissance as the starting point of most cyberattacks. ELLIO showed how organizations can stop threats at this early stage by limiting what attackers can see and access, using techniques such as network masking against unwanted scanners and modern IP blocking at the perimeter.

Mask your network against scanners

Today, hackers often use scanning services like Shodan and Censys to find vulnerable networks for attacks. ELLIO’s network masking technology blocks these scans by hiding the network from such tools. This makes it harder for attackers to find targets, reducing the risk of mass exploitation and opportunistic attacks. It’s a clear example of how ELLIO uses cyber deception and proactive defense to keep networks safe from malicious actors.

Reduce SIEM Noise efficiently

While network masking hides your assets from external scanners, it’s only part of the picture. Reconnaissance activity that does reach your network can trigger a high volume of alerts in SIEM and SOAR systems, many of which are low-priority or false positives.

At it-sa, ELLIO showcased its real-time mass exploitation and reconnaissance intelligence, designed to reduce SIEM noise by automatically filtering out non-critical events and accelerating automated response workflows. This enables Security Operations Centers (SOCs) to focus on real threats, minimize alert fatigue, and improve operational efficiency without adding extra staff.

Closing Thoughts

At it-sa 2024, ELLIO showed how teams can work smarter and defend more efficiently. Our focus is stopping attacks at their earliest stages, before they escalate and become costly to solve.
