CanadaEvery Credential Secured. Every Access Logged. Every Time
When you hand over HMRC credentials, payroll records, and self-assessment filings to an outsourcing firm, a policy document is not enough. Here is exactly how we protect what you've been entrusted with.
Why Data Security Matters the Most
The data you're sharing is regulated. The firm you share it with should be too.
Outsourcing accounting means sharing HMRC agent credentials, payroll records, VAT returns, and your clients' personal financial information. UK GDPR and ICO rules don't stop applying just because you've brought in external support. You need a firm that understands those obligations — and has the infrastructure to meet them.
- HMRC agent credentials and client files stored in isolated, encrypted vaults — never in shared cloud folders or third-party platforms.
- One dedicated accountant per client, background-verified before accessing any file — no shared access, no team pools.
- Role-based permissions so that only the assigned accountant can open your records. No exceptions, no workarounds.
- Every file is transferred over end-to-end TLS 1.3 encryption. Nothing leaves our systems unprotected.
Committed to Canadian & 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.
Private 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 of the clients move through secure portals, never via unauthenticated email or consumer file-sharing services.
Vetted, Dedicated Personnel
Background checks is done before any file is touched. Confidentiality is a contractual obligation — not a courtesy.
Logs, Audits and Alerts
Every file action is timestamped and attributed to a user ID. Real-time intrusion detection and quarterly audits keep our posture verified continuously.
Our Infrastructure
We run our own servers. Most outsourcing firms don't — and that difference matters.
Shared public cloud means your data lives 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.
No shared hardware, no co-mingling
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.
Power redundancy, continuous uptime
Diesel generator and UPS backup systems keep operations running without interruption during any power outage. .
Encrypted backups, every day
Automated daily backups with off-site encrypted replication. Full restoration with minimal recovery time if the unexpected happens.
Continuous threat monitoring
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 control. We remove 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.
Enterprise network only
Staff connect exclusively through our hardened office network. Home broadband is a known attack surface — we've removed it from the equation.
Company-issued Machines Only
Every device accessing client files is company-owned, encrypted, and endpoint-protected. Personal devices are not permitted on the operational floor.
Every workstation is monitored
CCTV covers every desk. Screen photography, shoulder-surfing, and internal misconduct have nowhere to occur undetected
Nothing leaves the building
No USB drives, no personal phones on the floor, no unauthorised printing. Your data doesn't 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.
NDA and data agreement signed
Before anything is shared, both parties sign a UK GDPR-compliant data processing agreement covering access, usage, retention, and deletion.
Secure portal transfer
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 allocated
One accountant or a small team assigned exclusively to your account, with RBAC permissions scoped precisely to your files — nobody else can see them
Delivery and secure 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 UK 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.
