DigiTechLog
audit ledger
DigiTechLog is the operating logbook for digital engineering teams. One immutable, search-ready ledger replaces the spreadsheet + Slack + Notion patchwork — and every entry is captured in under 90 seconds per event.
Four adapters write to the same append-only stream. Drop the SDK in your service, point a webhook at GitHub Actions, run the CLI from CI, or export your IaC plan — every event lands in the same immutable ledger with the same hash chain.
Typed clients for Go, Python, TypeScript, Rust, and Java. A single dl.append(event) call returns the assigned hash and root-pinned timestamp in under 80 ms.
Receive from GitHub, GitLab, CircleCI, ArgoCD, PagerDuty, Datadog, and Opsgenie. Every payload is HMAC-verified before it touches the chain.
digitechlog append --kind=deploy --actor=$USER --ref=$SHA runs in any pipeline. No daemon, no agent, no sidecar. 14,200-star open-source SDK on GitHub.
Terraform, Pulumi, and Cloud Custodian plan/apply hooks stream every resource diff into the ledger before it lands — so change records predate the change.
// Append a release event. Returns hash + chain head.
func RecordRelease(ctx context.Context, v string, canaryPct int) error {
ev := dl.Event{
Kind: "deploy",
Actor: os.Getenv("GITHUB_ACTOR"),
Service: "payments-api",
Version: v,
Canary: canaryPct,
Commit: os.Getenv("GIT_SHA"),
Env: "prod-us-east",
}
h, err := client.Append(ctx, ev)
if err != nil { return err }
log.Printf("ledger=%s head=%s", ev.Kind, h.Short())
return nil
}Each event references the hash of the event before it. Mutate one row, the entire chain from that point forward goes red — your auditors and your on-call engineer see the same fact at the same time.
Every event's hash is computed from its payload concatenated with the previous event's hash. The genesis event is pinned in an HSM-backed witness node in Austin and replicated to three independent cloud regions.
Run digitechlog verify --from=2025-01-01 --to=2025-12-31 and we re-compute every hash from the raw payloads against the stored chain head. Mismatches are surfaced with the exact row index and the byte that diverged.
Two independent engineering orgs in the Fortune-regulated segment replicated the chain in their own S3 buckets and verified 12 months of DigiTechLog events against their internal change tickets — zero discrepancies across 41,200 events.
Four views from the production workspace. Terminal-grade density, no decorative chrome, every pixel earning its place on a screen your auditor will eventually scroll through.
Four numbered panels. Frame them as ledger entries: each one is something your auditor will eventually ask for, already in the format they expect.
Across 600+ engineering orgs using DigiTechLog since 2021, mean time to root cause dropped 64%. The post-incident timeline assembles itself — every deploy, config push, and alert on the same time axis, every line hash-pinned.
One click generates a 200–400 page PDF covering a chosen time window — every event, approver, hash, and chain verification result. Each bundle is signed by DigiTechLog's HSM and counter-signed by your org's key.
SOC 2 Type II certified since 2020 · ISO 27001 certified since 2022 · HIPAA-compliant tier since 2023.
Most teams land in under four hours. We import change tickets, ServiceNow change records, and Airtable bases, recompute SHA-256 anchors against the original timestamps, and replay them into the new chain.
92% of new customers complete migration in < 4 hours.
SOC 2 CC7.2, CC8.1, ISO 27001 A.8.32 / A.8.34, HIPAA §164.312(b), PCI-DSS 10.5 — every control is annotated against specific event classes in the ledger so the auditor's evidence request maps to a saved filter, not a Slack thread.
“We replaced two spreadsheets, a Notion database, and a Slack channel with DigiTechLog in a Tuesday afternoon. Six months later our auditor pulled a signed bundle, verified the chain in 40 seconds, and closed the finding without a follow-up email.”
