At a recent industry meeting, a keynote speaker told a room full of credit union professionals that the number one cybersecurity threat facing their institutions was an advanced AI system that most in the audience had likely never heard of.
I looked around the room. The smaller credit union leaders—the ones managing institutions with ten or twelve employees, maybe one IT generalist, and a compliance officer who also handles member services and online banking—had the same expression.
That threat may be real for some institutions. It is not the one keeping most of them up at night.
I know, because I sat at dinner with a Director of Retail Operations who said just that.
“What was that guy even talking about?” he asked me.
What they are worried about is a teller clicking a link she should not have. A vendor with access to core systems that no one has reviewed in two years. A board that receives a cybersecurity report it cannot meaningfully evaluate. An incident response plan that exists as a document but has never been tested.
That gap—between the threats dominating industry conference stages and the operational reality of a smaller credit union—is one the industry is not talking about enough.
The same obligations, completely different reality
Smaller credit unions face many of the same threats as major financial institutions, often with fewer staff and fewer resources. The compliance obligations are largely the same. The examination expectations follow the same frameworks. But the resources, staffing, and operational context are entirely different.
A $900 million credit union may have a dedicated security operations center, a full-time CISO, and a team of analysts monitoring threats around the clock. A $150 million credit union has a part-time IT generalist, a compliance officer wearing multiple hats, and a board that meets quarterly. A $38 million credit union has a CEO that manages a relationship with an outsourced IT guy.
When the industry's cybersecurity conversation is dominated by enterprise-scale threats and enterprise-scale solutions, smaller institutions are left translating guidance that was not written for them into a context it does not quite fit.
What the real threat profile looks like
Business email compromise remains the most financially damaging threat for credit unions, followed by ransomware delivered through exposed remote access, credential stuffing attacks against online banking portals, and third-party vendor compromises.
These are not exotic threats. They are practical, human-centered vulnerabilities that exploit the ordinary moments of a workday—a rushed email response, a reused password, a vendor relationship that was never fully documented.
Attackers are increasingly using AI to scale phishing and social engineering campaigns at a speed and sophistication that traditional defenses cannot match. But the entry point is still human behavior. And that is something every institution—regardless of asset size—can address without an enterprise budget.
What smaller institutions actually need
The credit unions I work with are not asking for more complexity. They are asking for clarity.
Clear policies that reflect how the institution actually operates. Documented vendor relationships with defined responsibilities. Board reporting that leadership can understand and act on. An incident response plan that staff have actually practiced.
Institutions should concentrate their limited resources on high-impact controls—multi-factor authentication, privileged access management, system patching, and incident response planning. Some protections depend more on process discipline than budget.
That is a realistic, achievable standard. And it is exactly what examiners are looking for—not perfection, but evidence that leadership understands risk, has made deliberate decisions, and can demonstrate consistent oversight.
It’s what Fastek offers in our CORE solution for small credit unions. It’s a robust, exam-ready, compliance-driven security solution designed specifically for small institutions.
A different conversation
The credit union industry needs two cybersecurity conversations happening in parallel—one for the institutions with the resources to address sophisticated, emerging threats, and one for the institutions doing serious, important work with lean teams and limited budgets.
Conflating the two does not serve anyone. It leaves smaller credit unions feeling perpetually behind on a race they were never equipped to run.
The goal for an eight-person credit union is not to build an enterprise security program. The goal is to build a defensible one—proportional to the institution's size, aligned with regulatory expectations, and sustainable with the resources actually available.
That is the conversation worth having.
