Accounting firms process other companies' financial data. A single ransomware attack means instant losses, GDPR fines and lost clients. We build defence in depth, specifically for accountants.
Daily immutable backup, enterprise EDR, 2FA on everything that matters, quarterly audit.
A single click on a phishing email and all accounting databases are locked. If backup isn't isolated, it's encrypted too. Manual reconstruction is impossible — clients sue you.
The accountant's machine died with no centralised backup. Documents in local Excel, electronic seals on personal USB, all lost. Penalties arrive within 30 days.
Former employees' accounts stay active for months. Old VPNs, network drives, Google accounts — all accessible. Without access auditing, you never know who sees what.
You process financial data for hundreds of companies — you're a serious GDPR controller. Missing a Record of Processing can bring a fine of 4% of turnover.
Layered security plus your specific integrations (HMRC, MTD, Sage) — all under a single managed contract.
We migrate databases from individual machines to a centralised server with automatic backup. One single source of truth, accessible to all accountants.
Automatic end-of-day backup to cloud, encrypted and immutable (anti-ransomware). Restore within 15 minutes to any point in the last 90 days.
SentinelOne uses AI to detect ransomware behaviour before encrypting files. Automatically blocks and rolls back to the previous state.
Mandatory two-factor on email, VPN, RDP, HMRC, MTD portals. Phishing becomes useless — the attacker can't get in without your phone.
Mandatory documentation for accountants: Record of Processing, DPIA, processor contracts with clients, breach notification procedures.
Automatic connection to HMRC, cloud electronic signatures, automatic VAT submission via Making Tax Digital.
Problem: A similar firm in their network lost all client data after a ransomware attack. Backup was on a NAS connected to the network — also encrypted. Clients sued the accountants. The firm shut down in 6 months.
Our audit found:
Implementation in 4 weeks: SentinelOne EDR on all machines, Wasabi immutable backup (offsite, WORM, 90-day retention), mandatory Microsoft 2FA, disabled inactive accounts, complete Record of Processing + processor contracts with all 84 clients. Security Awareness Training for all accountants.
Result: 14 months without incidents. They won 3 new corporate clients precisely because of the GDPR documentation. The 2026 supervisory authority inspection passed with no observations.
We send an engineer with experience in accounting firms. Checks backup status, EDR configuration, former employee accesses, and GDPR compliance. You get a written report with prioritised remediation plan.
