Earn your clients' trust with every file you share.
Tax returns, financial statements, deal documents and HR files are what your clients care about most, and what attackers want. DekkoCORE replaces email attachments and generic client portals with zero-knowledge sharing that's as easy as email for your clients.

Give every client exactly the access they need, from view only to full permissions.
What's at stake in professional services.
Email as the default
Client data still moves as attachments, readable by every server and mailbox it passes through.
Client friction
Clunky portals push clients back to email. Security only works if it's easier than the insecure option.
Reputational exposure
One leaked client file can undo years of trust, and clients hold you responsible wherever the leak happened.
One sealed space for the whole job.
Client document requests
Ask clients for documents with a secure upload link that works in any browser.
Engagement signing
Send engagement letters and sign-offs for signature without leaving the platform.
Deal rooms
Share due-diligence material with buyers and advisers, with expiry and revocation built in.
Secure client messaging
Take sensitive conversations off email and into end-to-end encrypted threads.
Year-end, without the inbox
Request
The firm sends each client a secure document request.
Collect
Clients upload their documents, which are end-to-end encrypted on the way in.
Prepare
The team works on the files and raises queries with the client by secure message.
Sign off
The final return is sent for signature and the client's access expires automatically.
Zero-knowledge
Only the people you share with can open your files. DekkoSecure can't read them.
