Practical agency use cases
Communication & creative agency
Brand guidelines, mockups, campaigns, variations: a communication agency lives by the rhythm of creative back-and-forth with its clients. Versions are exchanged via email, approvals get lost in threads, and large files are sent using free tools with no guarantees.
Voltn structures the creative cycle: a dedicated space per client, branded sharing links, a reliable version history, and tracked approvals from the initial brief to the final deliverable.

with every send
Marketing & digital agency
Campaign assets, databases, analytics exports, multi-account deliverables: a marketing agency handles its clients' data just as much as their creative work. GDPR holds both the agency and the advertiser accountable, and major accounts audit their service providers.
Voltn provides the framework to meet requirements: data hosted in France, partitioned account access, full traceability of exchanges, and certifications that reassure procurement departments from the very start of the bidding process.

Press & PR Agency
Embargoed press releases, press kits, HD visuals, interviews: a press agency orchestrates the distribution of sensitive information to dozens of newsrooms, at the right time and not a moment before. If an embargo breaks, your relationship with both the client and the media suffers.
Voltn masters every step and controls the tempo: password-protected links, per-transfer expiration dates, and full download traceability so you know exactly which newsroom accessed which content.
trackable distribution
in real time
Audiovisual production
Rushes, edit versions, masters, post-production assets: video creates the heaviest files in the industry, shared between directors, editors, colorists, and clients. Hard drives are sent by courier, and free transfer services hit their limits long before the first rush is sent.
Voltn handles the volume: unlimited file transfers and uploads, centralized and replicated storage, and project-based access so everyone sees only what they need to.

FAQ
Where is the data hosted?
Exclusively in France, in data centres meeting Tier 3+ and Tier 4 standards. No transfer takes place outside the European Economic Area. Your data is beyond the reach of the Cloud Act.
How do you get creative work approved by a client with a full audit trail?
By sharing a secure, timestamped link: you know when the client viewed and downloaded the work. Version history keeps every stage, from first draft to approved deliverable.
How do you keep multiple clients' files separate within an agency?
With dedicated spaces per client or per project, and 7 levels of access rights. Each team member, freelancer or client only accesses their own scope, and every action is logged.
What is the professional alternative to free file transfer tools?
Voltn Share provides a professional framework: a contract, hosting entirely in France, a portal branded to your agency, password protection and traceability for every transfer. Everything free tools do not guarantee.
How do you send videos and visuals that are too large for email?
Through a secure Voltn Share link, with no size or format limit. 4K video, HD visuals and presentations are transferred encrypted, with full traceability of views and downloads.
But let's be honest, our cloud-based file storage and sharing solution is much easier.
