Maintained safeguarding targets
Predefined websites and supporting resources are maintained across education-relevant safeguarding categories. There are no test lists for your team to create or manage.
How FilterSentinel works
See what your web filter actually allows.
FilterSentinel tests your school’s filtering from inside the network being assessed. It uses centrally maintained KCSIE and education-focused targets to identify content that is blocked, unexpectedly accessible or needs further investigation.

Behind every result
Careful checks. Clear evidence.
FilterSentinel combines maintained safeguarding targets, known reference behaviour and multiple diagnostic signals to reach dependable conclusions.

- Multiple evidence signals
- Category-level insight
KCSIE & education focused
Known reference behaviour
Results from your school network are compared with reference scans, providing essential context for how each target ordinarily responds.
Multiple diagnostic signals
FilterSentinel considers request, response and network behaviour to distinguish filtering intervention from ordinary website or connection errors.
Category-level evidence
Your report combines an overall summary, safeguarding category performance and supporting evidence for unexpected or uncertain findings.

Clear statuses.
Useful next steps.
Turn every completed scan into clear, evidence-backed reporting for safeguarding leaders, governors, auditors and technical teams.
Choose the right level of detail, see how current the evidence is and trace every summary back to its verified source run.
Evidence-led by design
Clear evidence, careful conclusions.
FilterSentinel considers multiple signals and compares them with known reference behaviour. Ambiguous responses are flagged for review rather than automatically treated as filtering failures.
It supports filtering and safeguarding reviews but does not replace professional judgement or constitute regulatory certification.
