Cyber Security Messaging for Professional Services Firms

28 August 2026·5 min read

Quick answer: Clients now routinely ask law firms, accountants and financial planners how their data is handled before signing on, and most firms respond in one of two unhelpful ways — saying nothing at all, which reads as careless, or burying visitors in jargon and certification acronyms, which reads as either scary or not quite true. A good security statement is short, plain-English, and describes what you actually do — not what you wish you could claim. It builds trust precisely because it doesn't try to sound bulletproof. 🤍

Here's the uncomfortable bit: your clients are handing you tax file numbers, banking details, super balances, sometimes an entire financial history in a divorce file. They know that, and increasingly they're thinking about it before they engage you, not after. 💖 Most professional services websites say nothing about it — not because firms don't care, but because nobody's sure how to address it without sounding like an unread legal disclaimer or accidentally claiming a certification the firm doesn't hold.

What most firms get wrong

Two failure modes are common. The first is silence, which leaves security-conscious clients to assume the worst or ask a competitor instead. The second, among firms that do try, is overclaiming: "bank-level encryption," "ISO certified," or "fully compliant" when the firm hasn't undergone a formal audit or doesn't know what "bank-level" is meant to mean. This isn't just imprecise — a client who later has a data incident and finds the marketing overstated the firm's security posture has grounds for a genuinely bad conversation. The honest middle ground is describing your actual practices plainly, without borrowing authority you haven't earned.

A copy-paste framework for a data-handling statement

Use whichever of these five sentences are actually true for your firm, in this order, and drop any that aren't:

What you collect: "We collect only the personal and financial information needed to [complete your tax return / progress your matter / build your financial plan]."
Where it lives: "Your documents are stored in [name of platform, e.g. a secure cloud accounting system / practice management software], which uses encryption to protect data in transit and at rest." (Only state this if you've confirmed it with your software provider — most mainstream platforms do this, but check rather than assume.)
Who can see it: "Access is limited to the team members working directly on your file."
How long you keep it: "We retain records for the period required by [the ATO / your professional body / law], and no longer than necessary."
What happens if something goes wrong: "If we ever became aware of a data breach affecting your information, we would notify you promptly in line with our obligations under the Privacy Act."

Never write: "military-grade encryption," "100% secure," "hacker-proof," or any specific certification (ISO 27001, SOC 2, etc.) unless you hold current, verifiable certification for it.

A small accounting firm: Handling TFNs and bank details for 300+ clients, the firm added a short "How we protect your information" section to its new-client page, naming the cloud accounting platform it uses and its document retention period. No certifications claimed — just what's true.

A family law firm: Handling sensitive personal documents in separation matters, the firm added one paragraph to its engagement letter explaining that client portals are used instead of email for sensitive documents — which doubled as a nudge away from clients texting scanned bank statements.

A financial planning practice: Handling super and investment data, the practice worked with its licensee's compliance team to confirm exactly what could be claimed, then published a plain-language version on its website rather than the technical wording nobody was reading.

Where this messaging actually belongs

You don't need a standalone "Security" page with a padlock icon (though it doesn't hurt). The highest-impact placements are quieter: a short paragraph in your engagement letter, a line in your new-client welcome email, and a brief FAQ entry on your site. The goal isn't to make security a selling point that overshadows your expertise — it's to remove a quiet objection before it stops someone engaging you. If you work with a compliance team or professional indemnity insurer, have them sanity-check the wording once, particularly the breach-notification sentence, since obligations differ slightly by profession and state.

💡 If you use a well-known platform, name it. Saying "we use Xero, which encrypts data in transit and at rest" is more reassuring than a vague reference to "secure systems," because it's specific and verifiable rather than a marketing phrase a sceptical client has learned to tune out.

Mistakes to avoid

Claiming certifications (ISO 27001, SOC 2, Cyber Essentials) you haven't actually obtained
Using vague superlatives like "bank-level" or "military-grade" that can't be substantiated
Writing the statement in dense legal language nobody will read before signing
Publishing a breach-notification promise without checking it matches your actual obligations
Treating this as one-off — if you switch platforms, the statement needs updating

Frequently asked questions

Do we need a formal Privacy Policy as well as this statement?

Yes — a data-handling statement in your marketing copy doesn't replace a compliant Privacy Policy, which most firms are required to have under the Privacy Act. Think of the statement as the human-readable summary, the policy as the legal document it points to.

Should we mention a past incident if we've had one?

Generally no, unless legally required or a client asks directly — get advice from a privacy lawyer on disclosure obligations rather than deciding this from a marketing angle.

Can we say we're "Privacy Act compliant"?

Be cautious with absolute compliance claims. Describing specific practices ("in line with the Australian Privacy Principles") is safer than declaring blanket compliance, since compliance is an ongoing state, not a badge earned once.

Will this messaging actually influence whether someone engages us?

For some clients, especially in law and financial planning, yes — it removes a real hesitation. For others it won't register. It's a hygiene factor, not a strong selling point: absence can cost you a client, but presence alone won't win one.
