Mortgage brokers should avoid emailing sensitive documents or reusing passwords, enable multi-factor authentication, and think twice before entering client data into consumer AI tools, according to Mortgage Brain.
The warning comes as Mortgage Brain, the leading technology provider for the mortgage industry, announces it has achieved ISO 27001 accreditation, the internationally recognised standard for information security management.
ISO 27001 sets the global benchmark for managing information security and cyber risk. It requires organisations to embed security across their people, processes, and technology, and to be independently audited to ensure data remains confidential, accurate, and available when needed.
Working towards ISO 27001 was a company-wide effort, running alongside the development of Mortgage Brain’s evolving product suite. Data security has always been treated as a fundamental priority within the organisation, with robust controls and responsible practices embedded across the business. Achieving ISO 27001 recognises and independently validates that long-standing commitment. Preparing for the accreditation involved formalising security controls, documenting processes, and changing behaviours to make security part of everyday decision-making, not just an IT responsibility.
For brokers, ISO 27001 provides independent reassurance that:
- Client data is protected by design – it’s not an afterthought
- Security is embedded into daily operations
- Mortgage Brain operates to best-in-class, globally recognised standards
As brokers handle increasing volumes of sensitive personal and financial information, risks such as phishing, ransomware, human error, and third-party exposure continue to grow. As a result, data security is a must for any company handling sensitive client data, especially brokers, mortgage lenders and technology providers.
Top Data Security Tips for Brokers
- Use multi-factor authentication (MFA) everywhere possible
- Never reuse passwords across systems
- Don’t email sensitive documents
- Don’t paste client data into consumer AI tools
- If you wouldn’t want it public, don’t put it into AI
Cloe Atkinson, Chief Operating Officer of Mortgage Brain
“ISO 27001 accreditation shows that we are serious about data. With cases of cyber security on the rise, protecting data is business critical. Brokers can trust that Mortgage Brain is doing everything possible to handle their data, and that of their clients, as safely as possible, and we have been independently audited against best-in-class security standards to prove it. But this isn’t enough. Brokers also need to make data security non-negotiable. Just a few simple steps, such as using AI tools with common sense and not reusing passwords, can make a big difference.”
