Protect client data without slowing down the practice.
Tax advisors, auditors, law firms, notaries and consultancies handle records that need more than a shared drive and a password. We build networks, access models and backups designed around that reality.

How does a law firm or accounting practice protect client data from unauthorised access?
Client confidentiality is not just a professional obligation, it is a technical one that depends on how access, logging and encryption are actually built. That means access rights scoped to individual client files rather than the whole practice, logging that shows who opened which file and when, and encryption for data on servers, in the cloud and on mobile devices. NDVDL builds networks and access models for tax advisors, auditors, law firms and consultancies in Vienna, Lower Austria and Slovakia around exactly that requirement. A technical setup does not replace a legal assessment of what a specific practice must do, but it is the foundation that assessment gets built on.
What actually goes wrong in practices
Four patterns that keep showing up in tax, audit, legal and consulting practices.
Client files sent as email attachments
Documents, receipts and contracts get emailed back and forth, often unencrypted and with no record of who received what and when. Once a file lands in the wrong inbox, there is little that can be done afterwards.
Phishing and invoice fraud aimed at practices
Practices are targeted deliberately because they hold client funds, tax records and confidential files. Fake invoices and emails styled as internal requests are built to slip past standard spam filters.
Access not separated by client file
Often every staff member can open every file, regardless of whether they work on that engagement. If a dispute or an audit ever asks who accessed what and when, there is nothing to show.
Outages that hit right before a filing deadline
A server failure or a ransomware incident just before a filing or reporting deadline hits a practice differently, because the deadline itself cannot move. Without a working backup, the whole practice stalls, not just one workstation.
IT infrastructure for law firms and consultancies
Six building blocks that come directly out of how a practice actually works.
Firewall and email security
Firewall and email security tuned to phishing, fake invoices and malicious attachments, not just generic spam. That cuts the risk of a practice being compromised through a single well-crafted email.
Access models per client file
Rights are assigned per client file rather than across the whole practice, with logging of who accessed which file and when. That gives an audit trail without slowing down daily work.
Secure file exchange with clients
Instead of sending sensitive documents as email attachments, we set up a way for clients to upload and retrieve files securely. That closes one of the most common weak points in a practice's daily routine.
VPN and multi-factor authentication
For remote and hybrid work, we set up secured access into the practice network with multi-factor authentication. Access to practice software stays traceable and protected even from outside the office.
Connecting practice software and interfaces
We connect existing practice management software and interfaces to authorities into the network without interrupting daily operations. Which systems are involved in detail depends on the individual practice.
Server infrastructure, backup and archiving
We advise on whether an in-house server or a cloud setup fits the practice, and set up backups aligned with retention requirements. If something goes wrong, files and client records can be restored from there.

What projects for practices usually look like
Three scopes that come up regularly in practice.
Tax practice that needs remote work
A tax practice wants staff to work from home some of the time without exposing practice software directly to the internet. We set up VPN access with multi-factor authentication and align it with the existing software.
Audit or consulting practice running several engagements in parallel
Several auditors or consultants work on different client engagements at the same time and need separated access rights. We build an access model per client file, including logging, and segment the network accordingly.
Notary or law firm with long-term archiving needs
Deeds and case files need to be kept securely over long periods, even after an engagement has closed. We set up a backup and archiving approach that accounts for encryption and applicable retention periods.
