CanadaEvery Revenue Credential Guarded. Every Access Traced. Every Time.
When you hand over Revenue Commissioners' access, payroll records, and client tax returns to an outsourcing firm, a policy document is not enough. Here is exactly how we protect what you have been entrusted with.
Why Data Security Matters the Most
Irish data law doesn't pause when you outsource. Your obligations travel with you.
Outsourcing accounting means sharing Revenue Commissioners agent credentials, payroll records, VAT3 returns, CT1 filings, and your clients' personal financial information. Under Irish GDPR and DPC guidelines, your responsibilities as a data controller do not transfer to a third party — they remain yours. You need a firm that treats that seriously, not one that hides behind a privacy policy.
- Revenue Commissioners credentials and client files held in isolated, encrypted vaults — never in shared cloud folders or third-party platforms.
- One dedicated accountant per client, background-verified before touching any file — no shared access, no rotating staff pools.
- Role-based permissions mean only your assigned accountant can open your records. No exceptions, no overrides.
- Every file transfer runs over end-to-end TLS 1.3 encryption. Nothing leaves our systems unprotected.
Committed to Irish & International Security Standards
Security Architecture
Six independent controls. If one fails, five more hold the line.
Each layer targets a different vulnerability. Together they create a defence-in-depth model with no single point of failure.
Physical access control
Biometric entry, 24/7 CCTV, and visitor logs on every operational floor. No unauthorised person gets inside.
Dedicated On-Premise Servers
We own the hardware. Your data lives on servers we control exclusively not AWS, not Azure, not any shared cloud infrastructure.
MFA and Access Controls
Multi-factor authentication on every staff account. Each person sees only the files assigned to them, nothing beyond that scope. .
End-to-end Encryption
AES-256 at rest, TLS 1.3 in transit. Files move through secure portals — never email, never consumer file-sharing services.
Vetted, Dedicated Personnel
Background checks is done before any file is touched. Confidentiality is a contractual obligation — not a courtesy.
Dedicated Signed Staff & Background Checks
Background checks before any file is touched. Confidentiality is a contractual obligation — not a courtesy
Our Infrastructure
We run our own servers. Most outsourcing firms don't — and that is where risk lives.
Shared public cloud means your data sits alongside other organisations' data, on infrastructure you have no visibility into. Aone operates its own on-premise server facility, giving us full control over security, availability, and performance.
Dedicated Hardware, Not Shared Cloud
Your files never sit on the same server as another firm's data. We own it, we monitor it, we decide who can access it.
UPS Backup & Redundant Power
Diesel generator and UPS backup systems keep operations running without interruption during any power outage. .
Daily Encrypted Backups
Automated daily backups with off-site encrypted replication. Full restoration with minimal recovery time if the unexpected happens.
24/7 Network Monitoring & Intrusion Detection
Automated alerts for unusual access, failed logins, or suspicious behaviour — reviewed and responded to within minutes.
No remote access. No hybrid arrangements. No after-hours exceptions.
Home networks, personal devices, unmonitored screens, and shared living spaces are all attack surfaces a policy document cannot fully control. We eliminate that risk entirely — every team member works exclusively from our secured, monitored office. No exceptions.
No WFH Policy
Why No Work-From-Home Means More Security for You
Remote work introduces variables that cannot be controlled — unsecured home Wi-Fi, personal devices, shared living spaces, and unmonitored screen visibility. We completely eliminate those vulnerabilities.
No Unsecured Home Networks
Every device accessing client files is company-owned, encrypted, and endpoint-protected. Personal devices are not permitted on the operational floor.
No Personal Devices
Every device accessing client files is company-owned, encrypted, and endpoint-protected. Personal devices are not permitted on the operational floor.
Physical Screen Surveillance
CCTV covers every desk. Screen photography, shoulder-surfing, and internal misconduct have nowhere to occur undetected.
Controlled Exit Policy
No USB drives, no personal phones on the floor, no unauthorised printing. Your data does not leave our environment in any form.
Secure Onboarding Process
Getting Started — How Our Process Works?
From first conversation to live engagement — structured, signed, and fully traceable.
Signed NDA & Data Agreement.
Before anything is shared, both parties sign an Irish GDPR-compliant data processing agreement covering access, usage, retention, and deletion of all client data.
Secure Portal Access.
All documents arrive through our encrypted, access-logged portal. Every transfer is timestamped and attributed to a named user. No email, no shared drives.
Dedicated Team Assigned
One accountant or small team assigned exclusively to your account, with RBAC permissions scoped precisely to your files — nobody else can see them.
Delivery & Data Deletion
Deliverables sent via the secure portal. On your instruction, raw data is purged from our systems and confirmed to you in writing.
Built to IRISH Privacy Standards
At Aone Outsourcing, our security practices are designed in accordance with Canadian privacy requirements and internationally recognized security frameworks, helping CPA firms and businesses protect sensitive financial data with confidence.
