Prioritising data security is a must for mortgage brokers. You handle passports, bank statements, payslips and sensitive financial information every day so it’s critical that the systems, passwords and processes you use are keeping your client data safe.
At Mortgage Brain, achieving ISO 27001 accreditation reinforces our commitment to protecting broker and client data. But secure systems are only part of the picture. Brokers must also build strong data habits into daily practice.
Here are five practical steps every broker should follow.
Turn On Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is an extra layer of security on top of your password.
Instead of logging in with just a password, MFA requires a second form of verification -usually something you have (like your phone) or something you are (like a fingerprint or face ID).
Example:
You enter your email password as normal. Then you’re prompted to approve a notification on an authentication app (such as Microsoft Authenticator or Google Authenticator) or enter a one-time code sent to your phone. Without that second step, access is denied, even if someone knows your password.
You should enable MFA on:
- Email accounts
- CRM systems
- Mortgage sourcing platforms
- Cloud storage
- Accounting software
Your email account is often the biggest vulnerability. Protecting it properly reduces risk significantly.
Never Reuse Passwords
Password reuse is one of the most common causes of data breaches.
If one login is compromised, and you’ve reused the same password elsewhere, attackers can try it across multiple platforms.
Instead:
- Use a password manager
- Create long, unique passwords for every system
- Avoid predictable variations (e.g. Broker123!, Broker124!)
A password manager is far safer than reusing credentials.
Stop Emailing Sensitive Documents
Standard email is not a secure way to share documents.
Avoid sending:
- ID documents, such as passports
- Bank statements
- Payslips
- Mortgage paperwork
Use secure portals or encrypted systems wherever possible, such as the client portal that Mortgage Brain has built into its CRM Brain module. This easy-to-use portal means that customers can safely complete fact find data, upload documents, send secure messages and track their mortgage case progress.
If you absolutely must email a document, password-protect it and share the password separately. And remove attachments from inboxes once securely stored.
Be Careful with AI Tools
With increased use of AI tools in everyday life, it’s easy to become complacent about sharing all kinds of information with them, without thinking. But consumer AI tools, like ChatGPT, Gemini and Copilot, are not designed for regulated client data.
Do not:
- Paste client information, such as names, financial information or case details, into consumer AI tools
- Upload fact finds to summarise them
- Use AI to rewrite sensitive client communications using real data
As a rule:
If you wouldn’t want the information made public, don’t enter it into an AI tool.
Make Security Part of Everyday Behaviour
ISO 27001 required us to formalise controls, document processes, and embed security into everyday decisions.
You can apply the same principle to your business:
- Lock your screen when you leave your desk
- Check bank detail change requests verbally
- Double-check email addresses before sending documents (if you must use email)
- Regularly review who has access to your systems
- Remove access immediately when someone leaves
Top tips for locking your screen:
For Windows Computers, press “Ctrl + Alt + Delete” and select the “Lock” option or use the keyboard shortcut “Windows Key + L”.
For Apple Macs, go to the Apple Menu and choose “Lock Screen”, or use the keyboard shortcut “Command + Control + Q”.
Data Security Is Business Critical
Cyber threats targeting businesses continue to grow. As a broker, protecting client data also protects your reputation and your business continuity.
At Mortgage Brain, data security is non-negotiable, which is why we have built security into our platforms to make sure that all the sensitive data that brokers and lenders share with us is handled responsibly.
But ultimately the safe handling of your client data starts with you.
