City Under Siege: How Municipalities in the Valley of the Sun Can Stay One Step Ahead of Cybercriminals

City Under Siege: How Municipalities in the Valley of the Sun Can Stay One Step Ahead of Cybercriminals

By Dara Gibson, Cybersecurity Leader

In July 2025, the City of St. Paul, Minnesota suffered a significant cyberattack impacting police and fire systems, 911 communications, and municipal websites which were all disrupted. While full details are still emerging, early reports point to a ransomware operation that exploited outdated systems and limited internal cybersecurity staffing. The event paralyzed core services for over a week, cost millions in incident response and recovery, and reminded the nation’s municipalities of a hard truth: cities are increasingly on the front lines of cyber warfare.

Municipalities are prime targets for cybercriminals due to several key issues, such as, critical services, low downtime tolerance, aging or outdated infrastructure, significant budget constraints, and environments that are rich with data. A successful ransomware attack on a city doesn’t just disrupt operations, it can completely erode public trust, risks lives, and weakens the local economy.

Municipalities face several cybersecurity challenges. Securing a city requires navigating a unique threat landscape which may include disparate systems, 24/7 availability needs, and significant third-party risk exposure. The cyber risk landscape of municipalities may also face the top threats, ranging from ransomware attacks, phishing and credential theft, supply chain compromise, or Internet of Things (IoT) exploitation.

In many situations municipalities may outsource a good majority of the cybersecurity efforts. Security providers, either outsourced or in-house, should be cognizant of implementing cybersecurity proactive measures. For example:

·       Conduct Baseline Risk Assessments

·       Implement Zero Trust Architecture

·       Establish Incident Response Plans

·       Ensure Data Backup and Resilience

·       Coordinate with Community Partners, such as InfraGard Arizona Members Alliance

To be more proactive, local municipalities may want a call to action. Here are six options your city leaders can put in place to create a solid cybersecurity foundation for the municipality:
1. Establish a Municipal CISO Role
2. Conduct a Citywide Cyber Risk Audit
3. Engage in Tabletop Exercises, Cyber Incident Response and/or Business Continuity
4. Invest in Workforce Cybersecurity Training
5. Partner with State & Federal Cyber Units, AZ Department of Homeland Security of FBI Phoenix
6. Adopt Cyber Insurance, utilizing a cybersecurity insurance specialist

Cybersecurity is no longer just an IT issue for cities; it’s a public safety and governance priority. The St. Paul attack is a stark reminder that cybercrime doesn’t just target data; it targets people, infrastructure, and trust! For cities in the East Valley, the time to act is now, not after the breach. With strategic investment, strong leadership, and the right partnerships, municipalities can move from being easy targets to resilient defenders.

A New Cyber Reality: The CISA 2015 Sunset, Critical Infrastructure, and Cyber Insurance

Image
 By Dara Gibson Today, the Cybersecurity Information Sharing Act of 2015 (CISA 2015) has officially sunset, leaving a significant gap in the legal landscape that has governed cyber information sharing for a decade. If you are a leader in critical infrastructure, whether in the energy grid, water sector, or financial services, this is a pivotal moment for your organization and your cyber risk posture. As a longtime partner in the InfraGard community, I’ve seen firsthand how public-private collaboration can turn the tide against cyber threats. We’ve relied on that collaboration to understand emerging threats and prepare for the inevitable. Now, without the broad liability protections CISA 2015 provided, that sharing dynamic is fundamentally changed. What does this mean for your organization? 1. A potential chilling effect on threat intelligence sharing CISA 2015 offered companies a "safe harbor," shielding them from civil lawsuits, antitrust actions, and regulatory penal...

January 2026 Cyber Risk Brief: What Insurers Are Watching Closely

Image
By Dara Gibson, Cybersecurity Readiness Advisors As we enter 2026, cyber insurers are tracking a clear escalation in both the sophistication and speed of attacks. January’s top cybersecurity developments reinforce why underwriters are shifting from checkbox security to validated controls and resilience focused risk management. AI-Powered Deepfakes Fuel Social Engineering Losses Threat actors are rapidly adopting AI-generated deepfake audio and video to impersonate executives and public officials. These attacks are driving a surge in fraudulent wire transfers and credential theft, often bypassing MFA and traditional identity checks. From an insurance perspective, organizations without strong payment verification, call back controls, and employee training are increasingly viewed as high-risk exposures. Supply Chain Breaches Threaten Critical Infrastructure A recent breach at an engineering firm with ties to major U.S. utilities highlights the persistent danger of third-party risk. ...

How CMMC Level 2 Compliance Improves Your Ability to Obtain Cyber Insurance

Image
  By Dara Gibson, Cybersecurity Readiness Advisors Cyber insurance carriers have changed. Applications are no longer check-the-box forms. Underwriters now want proof of operational cybersecurity maturity, evidence of control effectiveness, and confidence that your organization can prevent, detect, and respond to modern threats like ransomware, business email compromise, and data exfiltration. Interestingly, organizations pursuing CMMC Level 2 are already building exactly what cyber insurers are looking for—even if they don’t realize it. Although CMMC is a requirement for companies working with the DoD, its control framework has become a powerful signal of reduced cyber risk for any organization seeking favorable cyber insurance terms. Here are five reasons why. 1) Documented and Enforced Access Control (AC) CMMC Level 2 requires strict implementation of: Role-based access control Least privilege enforcement Multi-factor authentication Privileged ...
