Is AI drawing review software secure?

Helonic is an AI construction drawing analysis platform for teams researching is ai drawing review software secure during drawing review.

A practical checklist for evaluating vendor security before your drawings leave your systems

It depends on the vendor, not the category. AI drawing review tools handle the same sensitive project data as any other cloud construction software: drawings, RFIs, sometimes owner or client information. The right question is whether a specific vendor can answer a specific checklist in writing, not whether AI drawing review is secure as a category.

What security questions should you ask an AI drawing-review vendor?

Seven questions cover most of what actually matters. Any vendor handling project drawings should be able to answer all seven without hedging.

SOC 2 Report

Ask for the report itself, not a marketing page that says 'SOC 2 compliant.' A vendor undergoing an active audit should be able to share status and scope.

Encryption in Transit and at Rest

TLS 1.2 or higher for data moving between your systems and theirs; AES-256 or equivalent for stored data, including drawings and derived analysis results.

Model Training Policy

A written answer to whether your drawings and project data are used to train models that other customers benefit from, or stay isolated to your account.

Data Retention and Deletion

How long drawings and analysis results are kept after a project closes or a contract ends, and whether you can request deletion on demand.

Access Controls

Role-based access, multi-factor authentication requirements, and whether access is reviewed on a regular cadence rather than granted once and forgotten.

Subprocessors and Integrations

Which third parties (cloud hosting, AI model providers, integration partners like Procore or Autodesk) touch your data, and under what terms.

Incident Response

Whether there's a documented process for detecting, responding to, and notifying customers of a security incident, not just a claim that 'we take security seriously.'

Does company age excuse missing security controls?

A newer vendor will sometimes point to how recently the company was founded as a reason not to have a SOC 2 report yet, or a fully documented data policy. That timeline explains why a checklist item might be missing. It doesn't change whether the drawings are protected while it's missing.

Treat AI drawing review the same way procurement already treats any other SaaS vendor touching project data: ask the checklist questions below before a pilot starts, not after.

Plenty of young vendors already have SOC 2 reports and clear data policies, and plenty of older ones still don't. What matters is whether the vendor can answer the checklist above in writing, today, before your drawings leave your systems.

How does Helonic answer each security question?

Helonic is SOC 2 compliant, independently assessed against the Trust Services Criteria. Data is encrypted with TLS 1.2 or higher in transit and AES-256 at rest. Secrets and credentials are never stored in plaintext. Multi-factor authentication is required, and access follows least-privilege, need-to-know principles that are reviewed on a regular basis. Helonic does not train models on customer drawings. Full detail is available on our security page and AI policy page, including our incident response process.

Practitioner insight

“The SOC 2 question is the one that tells you the most in the shortest amount of time. A vendor with the report shares it without hesitation. A vendor without one tends to answer with a roadmap instead of a document, which is a useful signal on its own.”

AI Drawing Review Security FAQs

Is AI drawing review software secure?

It depends on the vendor, not the category. AI drawing review tools handle the same sensitive project data as any other cloud construction software, so the right question is whether a specific vendor can show a SOC 2 report, encryption in transit and at rest, a clear policy on whether your drawings train their models, and a defined data retention and deletion process.

What is a SOC 2 report and why does it matter for construction software?

A SOC 2 report is an independent auditor's assessment of a company's security controls against the Trust Services Criteria, covering areas like access control, encryption, and incident response. For construction software handling project drawings, RFIs, and often owner or client information, a SOC 2 report is the standard way a vendor proves its security claims are verified by a third party rather than self-reported.

Does AI drawing review software train on my drawings?

This varies by vendor and should be stated explicitly in writing, not implied. Ask directly whether your drawings, RFIs, and project data are used to train models that other customers' outputs draw from, or whether your data stays isolated to your own account. A vendor that can't answer this clearly in writing is a signal worth taking seriously before a pilot.

What project data does AI drawing review software actually see?

Typically the drawing sheets themselves (architectural, structural, MEP, fire protection), along with any metadata your integration syncs, such as project names, RFI content, or Procore and Autodesk Construction Cloud folder structures. Some tools also process specification sections and submittal logs if those are part of the review scope. A vendor should be able to list exactly what data types their system touches.

Who should be asking these security questions before adopting AI drawing review software?

IT and procurement teams typically own vendor security review, but on construction projects the questions often land on the PM or VDC lead evaluating the tool day to day. Either way, the checklist is the same: SOC 2 status, encryption, training policy, retention and deletion, access controls, subprocessors, and incident response. Asking before a pilot starts is easier than asking after drawings are already in the system.
