Evidence needs a chain nobody can question.
Forensic software has a second audience beyond its users: opposing counsel, whose entire job is finding one gap in how your tool handled the evidence.
What usually breaks.
Evidence modified in place
Source data opened read-write because that was the default. Hashes taken after processing rather than before. The chain is broken at the first step.
Gaps in custody
Who accessed which artefact, when, and what they did with it, recorded partially or in a log anyone with database access can edit.
Reports that cannot be reproduced
Run the same analysis twice and get subtly different output, because of unordered results or an unseeded random. That difference is all a defence needs.
What we'd do about it.
Bug Fixing & Code Rescue
Write-blocked acquisition, hashing at every boundary, deterministic processing, and reports that regenerate byte-identically from the same evidence.
Security Hardening
Append-only, tamper-evident custody logs with integrity verification, so the record of who touched what can be defended under questioning.
QA & Testing
Verification against known reference images, and tests that prove the tool did not alter the source.
Fair things to ask.
Could your changes affect admissibility?
That's the thing we're most careful about. Write-blocked acquisition, hashing at every boundary, and nothing modified in place.
Can you make our reports reproducible?
Yes. Deterministic processing, so the same evidence produces byte-identical output every time it's run.
What about chain of custody?
Append-only, tamper-evident logs. If the record can be edited by anyone with database access, it isn't custody.
Would you testify about the tooling?
No. We build the software; expert testimony isn't a role we'd take on.
Can you validate against known reference images?
Yes. That's how we'd prove the tool didn't alter the source, rather than asking you to take our word for it.
We handle sensitive case data.
We work on synthetic or reference evidence. We don't want your real cases and won't ask for them.
Do you know the standards we work to?
Tell us which ones and we build to them. We won't claim accreditation we don't hold.
Can you make our processing faster?
Often, yes, but never at the cost of determinism. A fast tool that produces different output twice is worthless here.
