Frequently asked questions
Does the security checker hack or penetrate my website?
No. After ownership verification it makes a single read-only HTTPS request to inspect published response headers. It does not exploit vulnerabilities.
Can a strong header score prove my website is secure?
No. The score is a narrow response-header baseline, not proof of overall application security, vulnerability status or regulatory compliance.
Is the attack simulator a real cyberattack engine?
No. It uses controlled, fictional events and defensive-control scenarios for education. Real SIEM integrations and authorised telemetry testing are separate future capabilities.
Can these tools replace a certified DPCO or security audit?
No. The self-checklists guide preparation and do not provide a legal opinion, NDPC endorsement or accredited security assessment.
