Fastmail vs ShieldBox
for Law Firms
in Australia
Law firms and legal practices need email that protects solicitor-client privilege — not a US provider subject to CLOUD Act compulsion. See why Australian law firms are switching from Fastmail to ShieldBox.
Fastmail is Australian-owned but not Australian-hosted. Your emails sit on US servers — making them subject to the CLOUD Act and outside Privacy Act jurisdiction. No ASD Essential Eight alignment for regulated sector use.
Key Risks for Law Firms
Using Fastmail
Compliance Obligations for Law Firms
Why Fastmail cannot satisfy the compliance requirements of Australian law firms.
Fastmail stores email on USA servers. US CLOUD Act (or equivalent) can compel production of privileged communications without notifying you or your client. Australian hosting eliminates this risk entirely.
Every email containing client personal information sent via Fastmail is an ongoing APP 8 cross-border disclosure. Australian hosting is the only complete solution.
State law society rules require solicitors to protect client confidentiality. Offshore email creates a structural confidentiality risk that cannot be mitigated by contractual controls.
Email records relating to trust account transactions must be retained for 7 years and be producible on Law Society audit. Fastmail does not provide tamper-proof Australian-hosted archiving.
Why ShieldBox Wins for Law Firms
ShieldBox is the only email platform that eliminates CLOUD Act exposure for Australian law firms — protecting solicitor-client privilege at the infrastructure level, not just contractually.
Fastmail vs ShieldBox for Law Firms — FAQs
Can US authorities access my law firm's emails if I use Fastmail?
Yes. Fastmail is a USA-based service subject to USA law. US CLOUD Act (or equivalent) allows authorities to compel production of emails stored anywhere in the world — including in Australian data centres — without notifying you or your client. This creates a real risk to solicitor-client privilege. ShieldBox's Australian-hosted email eliminates this exposure.
Is Fastmail compliant with Australian law society professional conduct rules?
No. Law society professional conduct rules require solicitors to protect client confidentiality. Using Fastmail — which stores email on USA servers — creates a structural confidentiality risk. ShieldBox's Australian-hosted email satisfies law society obligations.
What email retention period applies to Australian law firms?
The Law Society recommends retaining client file correspondence for 7 years from file closure. Trust account records must be retained for 7 years. ShieldBox's 7-year tamper-proof archive satisfies both requirements — Fastmail does not provide equivalent Australian-hosted archiving.
Why are Australian law firms switching from Fastmail to ShieldBox?
Australian law firms are switching from Fastmail to ShieldBox primarily to eliminate CLOUD Act exposure to privileged client communications, satisfy APP 8 obligations, and meet law society professional conduct requirements. ShieldBox is the only email platform built specifically for Australian legal compliance.
