Nothing significant. Questions worth asking about Observability & Operations, Product & Engineering Maturity.

105 checks ran across 6 assessable dimensions. None found a significant problem; 5 raised something worth a question. 12 findings, each with evidence. One dimension cannot be assessed without an acquirer.

This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

1 base image floats: no version, or `latest`

adequate

1 of 4 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence
docker/falco/Dockerfile docker/falco/Dockerfile:1 — base image without a version

03.1

Bus factor 1: one account applies recent work

adequate

In the last 24 months, one account applied or wrote more than half of 763 non-merge commits, most of them written by others, among 84 authors; across all history, one contributor authored less than a quarter of 5,205. Every change passes through that one account, however many people write them. In a project with 84 recent contributors and 11 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

Evidence
git log --format='%cE' last 24 months: one committer more than half of 763 commits; bus factor 1; 84 authors

16% of bug fixes add or change a test

adequate

Of 189 fixes in the last 24 months, 30 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.

Notes that do not affect this rating
04.5

Effort is shifting from building to rewriting

adequate

Deleted lines per line added rose from 0.46 to 0.87 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

04.62

Releases are cut from another branch than the one surveyed

adequate

The newest release, 0.45.1, is not on the branch this survey read; the newest release on it is 0.32.1. The shipped product may differ from what this report describes. Survey the release branch too.

05.6

3 Dockerfiles run the application as root

adequate

No USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.

Evidence
no-USER-instruction docker/driver-loader-buster/Dockerfile — runs as root
no-USER-instruction docker/driver-loader/Dockerfile — runs as root
no-USER-instruction docker/falco-debian/Dockerfile — runs as root

05.60

Relicensed: GPL-with-exception → GPL-2.0 (2018-06-18) → Apache-2.0 (2018-09-20)

adequate

The root licence changed 2 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.

A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

Evidence
f43e5e6c3 COPYING — GPL-with-exception from 2016-05-11

05.65

1 advisory against this project in the last 24 months

adequate

The newest was published on 2025-04-30. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 1 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 0.32.1. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names falco with nothing tying it to this repository (CVE-2026-39292).

A note that does not affect this rating: it describes the project's advisory record, and no advisory in it is known to affect the surveyed commit.

Evidence
GHSA-7cq5-h4p2-h37p 2025-04-30: GHSA-7cq5-h4p2-h37p (low), fixed in 0.40 with krsi plugin: Unsupported detection of asynchronous io_uring operations

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 341 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

Evidence
telemetry-scan searched 341 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched

06.2

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

Evidence
logging-scan C++ source is not searched: C++ programs log through printf-style calls unless they take a library, and none of the 10 searched for is referenced

06.8

One request cannot be followed through the logs

adequate

Nothing in the service carries a request or correlation id, and there is no tracing. When a customer reports a failure, the log lines that belong to their request cannot be picked out from everyone else's.

Evidence
request ids no request id, correlation id or tracing found

A note that does not affect this rating
06.9

No error reporter is wired in

adequate

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

A note that does not affect this rating: notes like it are common in well-run projects.

Evidence
error reporting no error reporter initialised

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

6 checks against the running system follow from the findings above: what a buyer's engineer will try, how to run it first, and what to have ready. A paid survey of this repository includes them. See the tiers.

A paid survey of a public repository is also reviewed: a language model reads each finding against the code and withdraws only findings it judges the code contradicts, each listed with its reason. The review is a language model's reading of the findings against the code, and it can be wrong. It never adds a finding, never raises a band, and never removes a finding from a proven check or an advisory that affects the surveyed version.

What a person adds

The survey reads what the repository can show. The code cannot settle these questions, and on them this report states nothing. Each says where its answer lives: your own engineer, the company, or an assessor you choose can settle it. Questions marked measured open with something this repository shows.

Not rated: structurally not assessable from a repository.

  1. This is primarily a C++ codebase, with C alongside (46% of source files). Does your engineering organisation already run C++ in production, or would this be the first? 07.1
  2. The bulk of this system sits in userspace/, chart/, cmake/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (docker/docker-compose/README.md and 6 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2
  4. What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.

BOREHOLE READING NOT A CERTIFICATION DN0W-Z3PX-ZS3P 2026-10-22 · 4CEA537 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter DN0W-Z3PX-ZS3P at borehole.dev/verify.

The code commits to the 106 checks this run performed, the bands they produced, and the commit they were read at. It does not cover checks written since.

Put the mark in your README

The image is wrapped in a link to the verification page, so a reader can check it rather than take it on trust. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

Borehole reading DN0W-Z3PX-ZS3P, not a certification

Where this scan ran

This scan ran on ordinary cloud infrastructure (cloud-run), not in a hardware-isolated confidential VM. Nothing about it is attested by Google.

What an attested survey proves, and what it does not.

What this scan did with the repository — 7 steps

Written by the steps themselves as they ran, not described afterwards. A hand-written account of a data flow drifts the first time somebody changes the flow and not the account.

An automated reading of a repository's code and its history up to one commit, with public advisory records. It may be wrong, it is not legal, financial, investment or security advice, and it does not replace diligence by a qualified person. It is provided for information: nobody may rely on it (Borehole's terms, section 3).
