AI can’t fix weak infrastructure. Here’s how secure, flexible digital platforms and cybersecurity make AI truly member‑centric for credit unions.
Most credit unions don’t have a “technology problem.” They have an infrastructure problem that quietly limits every AI, digital, and member experience initiative they care about.
Here’s the thing about AI for credit unions: fraud models, smarter loan decisioning, and 24/7 member service bots only work if your digital infrastructure is secure, flexible, and well-governed. No amount of AI will fix a brittle core, a tangled vendor stack, or a board that treats technology as an afterthought.
That’s why Chris Sachse’s line hits so hard:
“Technology, in general, is really a board and CEO conversation.”
This post builds on his conversation from The CUInsight Network and connects it directly to our AI for Credit Unions: Member‑Centric Banking series. We’ll look at how digital infrastructure, cloud strategy, and cybersecurity set the stage for AI in member-centric banking—and what practical steps leadership teams can take right now.
Digital Infrastructure Is the Foundation of Member-Centric AI
If your infrastructure isn’t modern, secure, and adaptable, your AI strategy will stall or, worse, introduce new risks.
For credit unions, digital infrastructure is the combination of:
- Core and digital banking platforms
- Cloud (or on‑prem) environments where data and apps live
- Network design and security layers
- Identity and access management
- Data pipelines and integrations between systems
When this foundation is strong, AI use cases like fraud detection, loan decisioning, and member service automation become faster to deploy and easier to manage. When it’s weak, you end up with:
- Slow project approvals because no one trusts the security model
- Fragmented member data spread across legacy systems
- AI pilots that never get past “interesting demo” stage
Chris’s firm, Think|Stack, spends a lot of time helping credit unions move from that second category to the first. The pattern is consistent: infrastructure maturity directly determines AI readiness.
Why this matters right now
2025 is a tipping point. Members expect:
- Instant account opening
- Real‑time fraud alerts
- Helpful digital assistants, not just static FAQs
Vendors are shipping AI‑enabled tools faster than most IT teams can evaluate them. Regulators are sharpening expectations around model risk management, cybersecurity, and third‑party oversight.
The credit unions that win won’t just “buy AI.” They’ll treat digital infrastructure and AI as one strategy, owned by the board and CEO, not just IT.
Cloud Platforms: Your Shortcut to Secure, Scalable AI
The most practical way for credit unions to support AI initiatives is to ride on the infrastructure of bigger players—exactly what Chris points to when he talks about using the tech of companies like Amazon.
Put plainly: you don’t need to build your own cloud or AI stack. You need to use cloud correctly.
What “good” cloud strategy looks like for a CU
A member‑centric, AI‑ready cloud approach typically includes:
-
Hybrid or multi‑cloud design
Keep mission‑critical workloads where they’re safest and most compliant, but use public cloud for analytics, AI services, and digital channels. -
Security baked in, not bolted on
Use native cloud tools for identity management, encryption, logging, and threat detection. Tie this into your SIEM and incident response playbooks. -
Data architecture built for AI
Create a governed data platform where core, card, digital banking, contact center, and CRM data can be combined. AI without integrated data is just expensive automation. -
Infrastructure as code and automation
Use templates and scripts to deploy environments consistently. This makes it easier to stand up AI sandboxes, enforce controls, and recover quickly.
When credit unions follow this pattern, they suddenly find AI projects less scary. You’re not asking, “Is this safe?” on every decision; you’re plugging into a known-safe environment.
Cloud as an equalizer
Large banks have entire teams building this. Smaller credit unions can close the gap by adopting well‑architected cloud frameworks and working with partners who already understand credit union risk, vendor management, and NCUA expectations.
That’s the real benefit of following the Amazon and hyperscaler path: you’re tapping into billions of dollars of R&D and security investment—while staying focused on member value and governance.
Cybersecurity: The Non‑Negotiable Layer Under Every AI Project
Every AI initiative increases your attack surface:
- More APIs to digital banking and third‑party systems
- More sensitive member data flowing into models and tools
- More staff experimenting with new platforms and integrations
Chris is blunt about this: if you’re not serious about cybersecurity, your digital transformation work is just adding risk.
An AI‑ready cybersecurity posture for credit unions has a few must‑haves.
1. A real cybersecurity budget and multi‑year plan
Cybersecurity can’t live in the “we’ll see what’s left” part of the budget. Boards should be asking for:
- A 2–3 year cybersecurity roadmap
- Clear alignment with AI and digital banking initiatives
- Annual, measurable improvements (e.g., MFA coverage, patch SLAs, phishing resilience)
2. Zero‑trust principles
If you’re adding AI‑driven tools, adopt a zero‑trust mindset:
- Assume no user, device, or application is trusted by default
- Enforce strong identity verification and least‑privilege access
- Inspect and log traffic between internal systems, not just at the perimeter
This becomes critical when AI tools connect to member data or make decisions about money movement and loan approvals.
3. Incident response rehearsal
AI won’t prevent every incident. What it can do is speed up detection and triage—if your playbooks are current and your team is trained.
Run at least one annual tabletop exercise where the scenario involves:
- A compromised third‑party AI or analytics vendor
- Member‑facing impact (fraud, data exposure, or service disruption)
- Regulator and media scrutiny
The credit unions that rehearse these scenarios recover faster, maintain member trust, and are more confident experimenting with new AI services.
Agility and Resilience: Lessons from the Pandemic Era
During the early COVID period, credit unions that could adapt quickly—remote work, digital lending, contactless solutions—outperformed peers that were stuck waiting on vendors or manual processes.
Those same traits—adaptability, agility, and resilience—are what you need for AI‑driven, member‑centric banking in 2025.
From what Chris shared, the credit unions that navigated the pandemic best had a few things in common:
- Cloud‑based collaboration tools and secure remote access in place
- Digital lending platforms that could be tweaked quickly
- Strong vendor relationships and clear communication channels
The pattern is obvious: operational agility comes from infrastructure choices made years earlier.
Apply those lessons to AI
Ask your team a few blunt questions:
-
If we wanted to roll out an AI‑enhanced chatbot to all members in 90 days, could we?
- Do we have the APIs, data access, security reviews, and vendor management frameworks to move that fast?
-
If an AI‑driven fraud tool flagged 3x more cases overnight, could our processes and staffing keep up?
- Are operations and technology aligned, or do they live in different universes?
-
If a regulator asked us to explain how our AI models treat protected classes, could we answer confidently?
- Do we have documentation, monitoring, and model governance in place?
If the honest answer to any of those is “not really,” you don’t have an AI problem. You have an infrastructure, governance, or process problem. Fixing those will benefit every digital project, not just AI.
Practical First Steps: From Boardroom Vision to Member Outcomes
AI for credit unions should always come back to a simple question: How does this improve the member’s experience or financial health?
Here’s a practical sequence I’ve seen work, especially for mid‑sized credit unions.
1. Make technology a standing board and CEO topic
Chris is right to push this. The board doesn’t need to debate Kubernetes versions, but it does need to understand:
- Where your infrastructure is today (on‑prem, hosted, cloud, hybrid)
- How that supports your 3–5 year member experience vision
- What risks and investments come with AI, data, and cybersecurity
Have management present an annual Digital & AI Readiness Briefing that covers infrastructure, security, data, and member‑facing innovation.
2. Map AI use cases to infrastructure capabilities
Instead of starting with “What AI tools should we buy?”, start with:
- Fraud detection using internal and external data
- AI‑assisted underwriting for faster, fairer decisions
- Member service automation for common requests
- Personalized financial wellness insights in digital banking
Then ask, for each use case:
- Do we have the data, clean and accessible?
- Do we have secure infrastructure to run and monitor this?
- Do we have processes and people ready to adopt it?
You’ll quickly see where infrastructure upgrades unlock multiple use cases at once.
3. Build a minimum viable “AI‑ready” stack
You don’t need a giant transformation program. Focus on a minimum viable foundation:
- A secure cloud environment aligned with your security policies
- Centralized logging, monitoring, and identity management
- A basic data platform that brings together core, digital, and card data
- Clear vendor management and procurement process for AI tools
From there, start with one or two high‑impact, low‑risk AI pilots tied directly to member value—often fraud alerts or smarter digital service are good starting points.
4. Invest in people and communication
Chris ends by emphasizing collaboration and empowering people. He’s right. Tools don’t change member experience—people and processes do.
For each AI initiative, define:
- Who owns it (business + technology co‑owners)
- How frontline staff will be trained and supported
- How you’ll explain the change to members, in plain language
The more transparent you are—internally and externally—the easier it is to scale AI responsibly.
Where AI‑Ready Infrastructure Takes Credit Unions Next
Digital infrastructure, cybersecurity, and cloud strategy might sound abstract, but they decide whether your credit union can actually deliver member‑centric AI or just talk about it in planning sessions.
When boards and CEOs treat technology as a core strategic topic, a few things start to happen:
- AI becomes a practical tool for better member experiences, not a buzzword
- Security, compliance, and innovation reinforce each other instead of competing
- Frontline teams feel supported, not threatened, by new tools
As this series on AI for Credit Unions: Member‑Centric Banking continues, we’ll go deeper into specific AI use cases—fraud, lending, member service, and financial wellness. But all of them assume one thing: a dependable digital platform that’s flexible, nimble, and secure, just as Chris describes.
If your credit union is serious about AI, start by asking: Is our infrastructure ready to support the member experience we’re aiming for? The sooner that answer is “yes,” the sooner AI stops being a risk and starts becoming a strategic advantage for your members.
