Editorial training track
- HackWatch source verification workflow for advisories, CERT notices and researcher reporting
- Incident update and corrections procedure for evolving cyber incidents
- Editorial standards for practical response guidance, canonical coverage and user-first alert maintenance
- Founder review workflow for user-facing phishing, recovery and web-safety pages

Editorial methodology
- Separate first-hand web-portal experience from specialist incident-response claims so readers can judge the scope of expertise.
- Use HackWatch's own tools, reports and user-facing workflows to add practical observations that generic summaries cannot provide.
- Cite primary advisories, CERT guidance, vendor notices or official public resources when the article touches active threats or recovery steps.
- Escalate deep forensic, malware or threat-intelligence claims to specialist review when the claim goes beyond founder/web-security experience.

Reviews HackWatch pages where practical web-portal experience, phishing prevention and user-facing account safety are central to the guidance.
Connects incident reporting to recovery playbooks, tool output and first-hand observations from running public web properties.
Keeps founder-level authority transparent by avoiding unverified claims about SOC, CERT, forensic or red-team employment history.
Editorial standards applied by Artur Ślesik
- Use real founder experience where it applies and cite primary sources where specialist security evidence is required.
- Add first-hand observations from HackWatch tools, web publishing practice or user workflows instead of publishing generic AI-style summaries.
- Do not present planned certificates, target credentials or invented security employment history as current authority.
