Cisego

Cisego is a private company headquartered in Warsaw, Poland, that specializes in cybersecurity consulting and software development. Founded in 2012 by former employees of the Polish Cybersecurity National Centre, the firm initially focused on providing penetration testing services to small and medium enterprises. By 2016 it expanded its portfolio to include managed security services, incident response, and threat intelligence feeds tailored for European regulatory compliance such as GDPR and NIS Directive.

The company’s flagship product, the Cisego Sentinel platform, is an integrated security information and event management (SIEM) system that leverages machine learning to detect anomalous network activity. Released in 2018, Sentinel supports real‑time correlation of logs from firewalls, endpoint agents, and cloud infrastructures. It also offers automated playbooks for common attack scenarios, which has been cited by industry analysts as reducing mean time to detect (MTTD) by up to 40 % in pilot deployments.

Cisego has partnered with several European governments to help strengthen critical infrastructure security. In 2020 the firm completed a contract with the German federal office of information technology to secure data centers used by the Ministry of Defence. The company also collaborates with academia, sponsoring research projects at the University of Warsaw on adversarial machine learning.

Despite its growth, Cisego has faced criticism over the perceived lack of transparency in its data handling practices. In 2021, the European Union’s Data Protection Supervisor issued a formal inquiry into the company’s data retention policies, prompting Cisego to publish a revised privacy statement and adopt a third‑party audit for its platform.

Cisego continues to expand globally, establishing a partnership with an Australian cybersecurity consortium to deliver joint threat intelligence services across the Asia‑Pacific region. The firm's current strategy emphasizes integrating zero‑trust architecture principles into its consulting practice and expanding its market share in the European cloud‑security sector.
