Every ATO Credential Secured. Every Access Logged. Every Time.
When you hand over ATO credentials, BAS lodgements, and client tax returns 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
Your clients' tax information is no joke. The firm in charge of it has to as well.
When you outsource accounting, you provide your ATO agent information, your payroll information, BAS and IAS lodgements, SMSF data and your clients' personal financial information. When you engage external support, your obligations as a registered tax agent do not pass to them; they remain your responsibility. You have to look for a firm that has the infrastructure and is aware of that.
- Agent credentials and client files are stored in separate, secure vaults and are not shared in cloud folders or third-party platforms.
- A separate accountant for every client who is vetted before accessing any file, and no sharing of accountants, no rotating staff accountants.
- Role-based permissions mean that your assigned accountant is the only one who can open your records. No exceptions, no workarounds.
- All file transfers are encrypted and end-to-end with TLS 1.3. There is not a single thing that leaves our systems unprotected.
Committed to Australian & 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 Security
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.
Vetted, Dedicated Personnel
Background checks before any file is touched. Confidentiality is a contractual obligation — not a courtesy.
End-to-end encryption
AES-256 at rest, TLS 1.3 in transit. Files are moved through secure portals never email, never consumer file-sharing services
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's where breaches happen.
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.
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 so that there is no 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 comprehensive data processing agreement that covers access, use, retention, and deletion of all client data.
Secure portal transfer
All documents we receive 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. Upon your instruction, the raw data is purged from our systems and confirmed in writing to you.
Built to Australian Privacy Standards
At Aone Outsourcing Solutions, our security practices are designed in accordance with Australian tax and privacy requirements and internationally recognised security frameworks, helping accounting firms and businesses protect sensitive financial data with confidence.
