None is an official product, certification, assessment or representation of any employer, regulator, public authority or standards body, and none provides legal, regulatory, compliance or professional advice. Material decisions should be validated against the applicable legislation, competent authorities and qualified professional advice. ### CyberPulse Canonical: https://cyberpulse.iliadis.net/ A probabilistic and statistical cybersecurity posture assessment. It uses 25 high-level executive questions and statistical inference, including Monte Carlo analysis to represent uncertainty, to infer a broader control posture. It is a faster, directional starting point than a detailed control-by-control assessment, and is intended to highlight areas that may warrant further investigation. Methodology and disclaimers on this site: https://www.iliadis.net/cyberpulse.html Independently developed. It is not an official tool, certification, assessment or representation of the Greek National Cybersecurity Authority. Its results are indicative and should not be treated as a cybersecurity audit, compliance assessment, certification, professional advice or definitive representation of an organisation's security posture. ### ThreatPulse Canonical: https://threatpulse.iliadis.net/ A threat-intelligence and vulnerability-prioritization application. It collects and normalizes current cyber-threat information — including sources such as the CISA Known Exploited Vulnerabilities (KEV) catalogue — and applies prioritization and scoring to help security professionals focus attention on the vulnerabilities and threats most likely to matter, rather than on unfiltered feeds. Prioritization supports, rather than replaces, professional judgement. It reflects the sources and scoring applied at the time of viewing, and is not an assessment, certification or endorsement by CISA or any other authority. Because the application presents live feed content, individual threat records, counts and scores change over time and are therefore not reproduced here. ### EU Cyber Incident Canonical: https://www.iliadis.net/eucyber/ An executive regulatory incident-discovery and SLA (service-level agreement) engine. It helps classify a cyber incident against DORA, NIS2, GDPR, the EU AI Act and the Cyber Resilience Act, and presents the applicable actions, deadlines and supporting legal references, so that cybersecurity, technology, risk and executive teams can see the potential regulatory spread of an incident and what may require attention first. It is a preliminary discovery and educational simulation tool, not legal, regulatory, compliance or professional advice. Legal texts, regulatory materials and deadlines are attributed to their respective instruments and authorities, not to Dr. Iliadis. Users should validate material decisions against the applicable legislation, competent authorities and qualified professional advice. ### QuickRisk — FAIR-Inspired Canonical: https://quickrisk.iliadis.net/ A FAIR-inspired quantitative cyber-risk assessment tool. It uses probabilistic modelling and quantitative analysis to explore the possible range of loss, likelihood, loss exposure, uncertainty and risk drivers for defined cyber-risk scenarios, instead of presenting risk as a single deterministic score. It is intended as a rapid, practical starting point for turning cyber risk into a more decision-oriented view. It is not a substitute for a full FAIR analysis, a detailed risk assessment, professional judgement or organisation-specific quantitative modelling. Results should be interpreted in the context of the assumptions and information entered into the assessment. ## Professional links - Executive profile and CIO/CISO positioning: https://www.iliadis.net/leadership/ - Biography, career and professional narrative: https://www.iliadis.net/about/ - Professional Snapshot (CV): https://www.iliadis.net/docs/cv/ - Certifications and credential inventory: https://www.iliadis.net/certifications/ - Contact: https://www.iliadis.net/contact/ - LinkedIn: https://www.linkedin.com/in/johniliadis/ ## Personal statement and non-endorsement > The views and opinions expressed on this website are solely his own and do not necessarily reflect the official policy, position, or endorsement of any current or former employer, organization, or authority with which he may have been associated.
