How cyber threats can derail advisors’ books of business

When financial professionals think about risk, they often focus on the external: volatile markets, interest rates, economic cycles or client liquidity. But one of the most destabilizing risks facing your business today may be lurking inside your own systems. 

Cyber attacks are no longer a fringe issue or a “tech problem.” They are an existential threat to any business that manages sensitive client data. And it’s not just about the financial harm your business may not be able to recover from. Once client trust is broken, your book of business begins to erode fast. 

Trust is the real currency 

If you’re not thinking of your businesses as a target for cyber attacks, you’re not alone. The majority of Canadian small businesses think they’re too small to be an attractive target. Forty per cent believe they have, host or use data that exposes them to the risk of a cyber attack, according to a BDC survey published earlier this year. 

But consider this: 

Thanks to AI, cyber attacks are now automated, ultra-real and scalable. That means there’s no such thing as “too small to target.” 

In the past year, 73% of small businesses in Canada experienced a cyber security incident, ranging from phishing attempts and ransomware to data breaches and denial-of-service attacks, found the BDC survey.

Over 40% of small businesses hit by a cyber attack in Canada said it cost them at least $100,000, according to an Insurance Bureau of Canada article published October 2024. That’s because it’s often easier for cyber criminals to try and squeeze a few thousand dollars out of multiple smaller, vulnerable businesses than to try hit a larger firm with more robust cyber defenses.

And while money may be recovered, trust often can’t. Reputational harm from cyber attacks have quadrupled since 2018 and is driving more customers away. 

Last year alone, 28% of Canadian businesses said their reputation was damaged by cyber attacks, while almost just as many said it cost them customers, according to data from CIRA published last year.

Why you’re being targeted 

Financial advisors and planners in particular, are a prime target.

You hold sensitive and therefore valuable information about your clients, whether it’s their banking info, insurance details, ID documents, SINs or tax files.

This means you face a range of cyber attack types, from ransomware that can cripple your entire business and cost millions to resolve, to a stealthy attack targeting one of your clients. 

One advisor client we recently helped faced a $10M ransom demand; another lost $20,000 after his client clicked a phishing link allowing a Gmail account hack.

If you haven’t already been targeted, you will be.

Cyber risk is a business risk 

As a financial advisor, cyber threats can hit your business in four key ways: 

• Client trust & reputation: A data breach or scam can make even long-time clients question your safeguards and look for someone else to trust with their financial future. 

• Operational downtime & recovery and restoration: Recovering from a cyber incident takes time, people, and money. Every day offline is lost revenue and lost momentum. Canadian small businesses collectively spent $300 million recovering from cyber incidents in 2023, according to Statistics Canada data released in October 2024. It now takes businesses an average 88 days to detect and contain stolen or compromised credentials, which is the top attack vector, says IBM’s Cost of a Data Breach Report 2025. 

• Legal and regulatory exposure: New privacy and data laws require notification and remediation. You could face steep penalties if you fall short. 

• Third-party risk: In just the last 12 months, more than half of Canadian businesses suffered a cyber attack and 58% of those attacks were linked to their supply chain or vendors, according to QBE Canada research quoted in an article published in Canadian Underwriter in June 2025. As your businesses becomes more interconnected and Cloud-service based, your digital attack surface widens, creating more doorways for cyber criminals to exploit. 

Predict & prevent: a smarter approach to cyber risk 

Mitigating cyber risk means shifting from response to anticipation. Think of a cyber threat as something you should – and can – get ahead of, not scramble to fix after it happens. Because prevention is always better than loss. 

A “predict and prevent” approach includes: 

• Mapping your digital footprint: Know what data you hold, where it’s stored and backed up, who has access and where the weak spots in your digital attack surface are. 

• Monitoring threats: Continuously stay alert to breach attempts, credential leaks or suspicious activity mentioning your business or clients on the dark web. 

• Training your team: Human error is involved in over 95% of data breaches in 2024, according to a study by Mimecast, cited in an article published by Infosecurity Magazine. Regular cyber security and awareness training, including identifying phishing attempts, is the cheapest form of risk mitigation. 

• Verifying client communication protocols: Never approve financial transactions based solely on an email or text, even if it “looks right.” 

• Testing your response: Do you have an incident response and recovery plan for cyber incidents? Have you ever rehearsed it? 

Even qualifying for cyber insurance now often means proving you have Multi-Factor Authentication (MFA), data encryption and strong password policies in place.

Prevention isn’t optional anymore, it’s necessary. And partnering with a cyber insurance provider that understands and supports this, can make all the difference. 

The path forward 

Start with one small step: book time to map out your digital risks. Review where your most sensitive data lives, who touches it and how it's protected.

From there, begin building the habits, protocols and partnerships that will help you predict and prevent the cyber threats that stand in your way. 

Protecting your book of business means protecting the trust it’s built on.
