Founder-Led IoT Audit Consulting

Audit the IoT system your team is worried about before launch pressure or customer scrutiny forces the issue

Combotto helps engineering-led teams get a fast, evidence-backed view across the gateway, MQTT, cloud ingest, identity, and observability path that matters most right now. Start by sharing the path you want reviewed, then scope the smallest audit that gives your team a decisive picture of risk.

Best fit

1-3 assets under pressure

Output

Findings, evidence, backlog

Next step

Audit -> Sprint -> Retainer

  • Best when a launch, enterprise review, incident, or scale-up means the team needs evidence fast.
  • Start by sharing the path you want reviewed, define the selected scope, then only expand into implementation or ongoing review where the audit says it matters.
  • Work directly with Thomas Bonderup on scope, evidence review, and the remediation path.

Send the asset or message path, the pressure behind the request, and the timing window. You will get a same-business-day reply with likely scope and the next practical step.

Thomas Bonderup

Senior IoT Consultant

MQTT, gateway, and edge-to-cloud audit work for teams under launch, customer, or scale pressure.

Thomas Bonderup

Secure edge-to-cloud systems with a focus on gateways, MQTT infrastructure, production reliability, and observability.

Why teams bring me in

  • Enterprise review and launch-pressure audits for teams that need evidence fast, not a long discovery cycle.
  • System-level reviews across gateway, broker, ingest, identity, TLS, buffering, and telemetry paths.
  • Decision-ready findings with owners, verification steps, and a clear next move for leadership and engineering.

You work directly with me on scoping, evidence review, and the remediation path. No handoff to a generic delivery bench.

Engagement path

Start with the audit that gives leadership and engineering the same picture

Combotto is not a generic services menu. The commercial path is designed to move from evidence to implementation to drift control without paying for a broad discovery cycle twice.

Typical reasons teams start now
  • Enterprise customer scrutiny is rising faster than architecture confidence.
  • Telemetry gaps or retry/buffering uncertainty are making the pipeline hard to trust.
  • Prototype-era gateway and ingest decisions are now under production pressure.
What happens after the audit
  • The Sprint fixes the highest-impact issues first and re-runs checks for before/after evidence.
  • The Retainer keeps posture from drifting with release-based or monthly delta reviews.
  • The team can also stop after the audit and execute the backlog internally if that is the right fit.
Audit
Fixed scopeAbout 1 weekFast clarity

A focused review of the selected edge-to-cloud path so your team can see where security, reliability, and telemetry risk is concentrated first.

  • Selected-scope audit: review the gateway, broker, ingest, identity, and observability path under pressure.
  • Decision-ready findings: evidence, priorities, and owners your team can use immediately.
  • Remediation backlog: clear next steps with verification guidance.
  • Strong stopping point: use the backlog internally or continue into a focused sprint.

Typical engagement: fixed-scope starting point

Sprint
Implementation2-3 weeks

A focused hardening pass on the issues most likely to hurt uptime, customer trust, or future scale.

  • Fix the highest-impact issues first across identity, TLS, buffering, durability, or monitoring.
  • Re-run checks and produce before/after evidence so improvement is visible.
  • Keep scope tight enough that the sprint finishes materially stronger than it started.
  • Leave engineering with clearer guardrails and a cleaner next priority set.
Retainer
AdvisoryOngoing

An evidence-backed review cadence for teams that want to prevent silent drift after the audit and first hardening pass.

  • Release-based or monthly delta reviews on what improved, regressed, or still needs attention.
  • Leadership-ready posture updates without turning this into a heavy managed service.
  • Reprioritize when customer pressure, architecture, or operations rhythm changes.
  • Use disciplined expert cadence rather than vague advisory hours.

Review case study

Proof-led handoff

See the same gateway path become an audit finding set, a hardening sprint, and a retainer review surface

This section is here so buyers do not have to infer how Combotto works from generic claims. It shows one concrete proof chain, explains what each artifact means, and makes the commercial handoff between Audit, Sprint, and Retainer easy to follow.

Gateway before and after proof

One gateway path, three proof artifacts, one clear Audit -> Sprint -> Retainer story.

You are looking at the same Raspberry Pi gateway path at three points: before hardening, after hardening, and in the ongoing review that keeps the improved state from drifting over time.

Before

Exposed posture · 4 findings

After

Hardened path · 0 findings

Ongoing review

4 controls improved · 0 regressions

What this proof chain actually shows

This is not three unrelated screenshots. It is one straightforward commercial sequence on one gateway path: the audit shows the problem, the sprint proves the fix, and the retainer keeps the improved state under review.

  • The audit gives leadership a clear view of risk instead of a vague architecture concern.
  • The sprint stays honest because improvement is visible on the exact path that was reviewed.
  • The retainer gives future releases a hardened reference point instead of relying on memory.

Leadership gets

A fast read on risk, concentration of problems, and whether the next move should be to harden now.

Engineering gets

A backlog, clear verification cues, and a hardened reference point they can check against as the system changes.

If your own gateway, broker, or ingest path is under pressure, this is the shape of the first conversation: one path, one clear picture, and one clearer decision about what to do next.

Commercial read

Audit

The audit turns one risky path into a clear picture the team can act on.

Sprint

The sprint hardens that same path and proves the fixes held.

Retainer

The retainer keeps later releases anchored to the hardened state instead of quietly drifting.

Verification signal

The hardened gateway stayed healthy, rejected unauthenticated ingest, and accepted authenticated ingest on the same path that failed before hardening.

Health

Gateway stayed healthy

Buyer handoff

Start with the path leadership and engineering are already worried about. If the audit shows concentrated risk, turn the highest-impact items into a sprint. If the system needs ongoing assurance, keep the hardened state visible with release-based or monthly delta reviews.

The flagship case shows the strongest before-and-after proof. The broader reference library gives more delivery context once you want to compare similar systems and pressures.

1. Before hardeningAudit

The audit makes one risky gateway path easy to understand.

The baseline turns a vague gateway concern into a concrete starting point. Leadership can see that the path is at risk, and engineering can see exactly where controls are failing and what needs attention first.

Why it matters

This is what the audit is supposed to do: make the risk visible, package the evidence clearly, and leave the team with a remediation path they can actually use.

  • The top scorecards make posture obvious in seconds.
  • The table below shows which controls failed and what to do next.
  • It reads like a client deliverable, not a mockup or generic dashboard.
2. After hardeningSprint

The sprint hardens the same path and proves the change held.

After the hardening work, the same path is checked again. The posture moves from exposed to healthy, the findings are cleared, and the proof stays tied to the same system slice rather than drifting into a new scope.

Why it matters

This is what the sprint is supposed to do: fix the highest-impact issues first and prove the improvement on the path that triggered the audit.

  • Same asset and same audit surface, but with materially better control outcomes.
  • The second check keeps the story honest because the comparison is deterministic.
  • Verification is backed by healthy checks plus authenticated and unauthenticated ingest behavior.
3. Ongoing reviewRetainer

The retainer keeps the hardened state from quietly drifting.

The comparison report looks at the before and after state control by control. It shows what improved, confirms there were no regressions, and gives the team a durable reference point for release reviews or monthly check-ins.

Why it matters

This is what the retainer is supposed to do: keep future changes anchored to a known hardened state instead of relying on memory, reassurance, or guesswork.

  • Four improved controls and zero regressions is instantly legible.
  • A later release can be compared against the hardened state using the same report shape.
  • Leadership gets a compact before-and-after story while engineering gets concrete drift evidence.
