Cisco Umbrella Alternative for Architecture and Engineering Firms

Architecture and engineering firms run on big files and shared trust. A single Revit model or CAD set can be hundreds of megabytes, it gets passed between the firm, the client, structural consultants, and contractors, and it represents years of design IP. Many AEC firms protect all of that with Cisco Umbrella, because it was simple to turn on and it follows staff to job sites. The catch is that DNS filtering cannot see the one event that matters most here: a drawing set leaving the firm through an upload it was never meant to take.

Short answer: For architecture and engineering firms, the right Cisco Umbrella alternative is dope.security, an agent-based secure web gateway that inspects full URLs, TLS traffic, and file uploads on the device. It can see and control a CAD or BIM file heading to an unsanctioned destination, govern AI use, and do it without backhauling large transfers through a cloud proxy.

The data shape of an AEC firm

Three things define the risk. First, the files are large and move constantly between internal teams and external partners. Second, the work is distributed: project architects and field engineers work from site trailers, client offices, and home, not just HQ. Third, IT is lean relative to the value of the IP. DNS filtering, the heart of Cisco Umbrella, answers only whether a domain should resolve. It never sees the model file, the project folder, or the cloud account it is going to. We documented those blind spots in what Cisco Umbrella cannot see.

Where Umbrella falls short for design IP

An engineer uploads a Revit model to a personal Dropbox to keep working over the weekend. A junior drafter pastes structural calcs into a consumer AI tool. A subcontractor link gets reused for a file it should not carry. In each case Umbrella sees a request to a category that is probably allowed and lets it through. The protection a design firm needs is data-in-motion control, and that requires seeing inside the TLS session on the device. The difference between domain filtering and endpoint control is the whole argument, and we made it in Cisco Umbrella SIG versus an endpoint SWG and in endpoint DLP versus network DLP.

How dope.security protects the work

dope.security runs as an agent on each machine. It does full URL filtering and on-device TLS inspection, so a large upload is visible as it happens. Dopamine DLP can block, monitor, or warn when a drawing or sensitive document heads somewhere it should not, using a zero-retention API protected under US Patent 12,464,023. Because inspection is local, a 400 MB model transfer is not dragged through a cloud proxy first. For project files already living in OneDrive, SharePoint, or Google Drive, CASB Neural finds the externally shared and over-exposed ones.

AI without leaking the IP

Designers and engineers are using AI for code, calcs, specs, and renderings. Banning it sends the work to personal accounts. dope.security allows your firm's sanctioned AI tenant through Cloud Application Control while blocking personal logins, and Dopamine DLP keeps proprietary geometry and client data out of prompts. Umbrella can only allow or block the whole domain, which is the wrong tool for this.

Fits a lean IT team and distributed work

AEC IT teams are small and stretched across offices and sites. dope.security is one console, policy changes in minutes, and the agent travels with the laptop so site trailers and client offices get the same enforcement as HQ. Greylock Partners, a firm with a small, device-first IT footprint, left Cisco Umbrella for dope.security and signed in 27 days from first proposal, detailed in the Greylock customer story.

Is dope.security a good Cisco Umbrella alternative for AEC firms?

Will it slow down large CAD and BIM transfers? No. Inspection happens on the device and traffic flies direct, so big files are not dragged through a cloud proxy first.

Can it stop drawings from leaking to personal cloud or AI? Yes. Dopamine DLP inspects uploads and prompts in motion and can block or warn, and CASB Neural finds files already over-shared in SaaS storage.

Does it cover engineers working from job sites? Yes. The agent enforces the same policy off-network, which is a cleaner model than the Umbrella roaming client plus backhaul.
