Chain of custody & asset accountability

Every transfer.
Every timestamp.
Every record.

TAMPERLOGS records who had an item, when, where, and why, in an append-only, tamper-evident custody history for physical IT equipment and digital evidence alike. Every entry is cryptographically chained to the one before it, so any alteration is detectable.

The platform

One ledger.
Every custody event.

Track physical IT equipment and digital evidence under one chain-of-custody model. Assets do not have an editable owner field. They have a history you can trust.

01Append-only event historyAssign, transfer, check-in, check-out, decommission. Logged permanently, never edited or deleted after the fact.
02Tamper-evident, hash-chainedEach entry is cryptographically linked to the one before it, so any alteration breaks the chain and is detectable.
03QR & barcode taggingTag physical items and scan them in from the browser camera. No separate app to install.
04Read-only API and directory syncPull assets and custody events into a system you already run, and feed in Azure AD and Active Directory audit logs.

DAILY DIGEST · 8:00 AM, ONLY WHEN THERE IS SOMETHING TO REPORT

When an asset reaches end of life, a disposition records how it was retired and closes out its custody history with a printable certificate, the same append-only record every other event gets.

05Dispositions with printable certificatesDestroyed, recycled, resold, or returned to vendor. The certificate is a view of the record itself, not a document sitting somewhere else.
06Vendor directoryPick repair shops, e-waste recyclers, and brokers from a shared list instead of retyping a name on every repair or disposition.

The workflow

Tag. Transfer. Verify. Dispose.

From the first tag to the final certificate, every action is timestamped and written to a custody chain that cannot be quietly rewritten.

01 / TAG

Tag

Register each asset and tag it with a QR or barcode. Scan it in from the browser camera, no separate app required.

02 / TRANSFER

Transfer

Every assign, transfer, check-in, and check-out writes a custody event: who had it, when, where, and why.

03 / VERIFY

Verify

Each entry is hash-chained to the one before it. If a date is altered or an entry removed, the chain breaks and it is detectable.

04 / DISPOSE

Dispose

Record end of life and print a disposition certificate that closes out the asset's custody history.

Flex Pricing, at launch

Priced by the band, not a tier

A flat platform fee plus your tracked assets and active storage, priced by the band you land in, not a named plan you outgrow. Public signups open once TAMPERLOGS reaches general availability.

$110 / mo platform access

Plus your tracked assets and active storage. Commit and save, billed upfront. No separate startup or activation fee. Graduated bands mean growing past a breakpoint never reprices the assets you already had.
