Every city just got a wake-up call on its cybersecurity budget.
When Suisun City was hit with a major cyberattack, its network shut itself down automatically as a fail-safe. During a live interview with KTXL FOX40 News, SIS Cyber Director of Security Technologies Scott Bly called that automatic shutdown “a very sharp way to approach this.”
It’s a silver lining in an otherwise costly incident. But it also points to a much bigger blind spot: most municipalities, and most mid-sized organizations generally, are one gap away from the same outcome.
What Happened in Suisun City
Suisun City’s network detected the intrusion and cut itself off before the damage could spread further. That’s not an accident — it’s what happens when segmentation and fail-safes are built in ahead of time, whether by design or by default. Not every organization gets that outcome. Most don’t have a network architected to protect itself when the humans aren’t watching in real time.
Why the Shutdown Worked — and What It Exposes
A self-isolating network is a good sign the underlying architecture had some resilience built in. Scott’s advice applies well beyond city government — it’s the same conversation SIS Cyber has with any organization sizing up its security posture against its budget.
Control Your Blast Radius
Separate critical systems — police, fire, water, finance — so a single compromised entry point can’t take the whole organization down with it. Segmentation isn’t a “nice to have” for enterprises with unlimited budgets. It’s the cheapest insurance policy against a cyberattack turning into a citywide outage.
Test Your Backups Before You Need Them
An untested backup isn’t a backup — it’s an assumption. Recovery plans fail quietly, in the moment you can least afford it, unless they’ve been run end-to-end beforehand.
Don’t Wait for an Attack to Find Your Gaps
Security blind spots don’t announce themselves. Attackers find them for you. A proactive gap assessment costs a fraction of what an unplanned network shutdown does — in downtime, in public trust, and in recovery labor.
The Budget Conversation Starts Now
If your organization — city government or otherwise — hasn’t budgeted for network segmentation, backup validation, or a real gap assessment, this is the moment to start that conversation, not after the next incident makes it mandatory.
SIS Cyber works with organizations that don’t have the budget for a full-time SOC but still need an objective, outside view of where they’re exposed. We find the gaps and hand over the exact fix — no unnecessary tools, no bloated governance framework, just a seamless path to a more resilient network.
