Outdated software is not just an inconvenience for local governments—it’s one of the most dangerous cybersecurity threats they face today. Legacy systems are defenseless against today’s sophisticated ransomware, phishing, and data breach tactics. Cybercriminals actively target these vulnerable platforms, knowing they can easily exploit unpatched weaknesses to cripple vital operations.
The stakes couldn’t be higher. When attacks strike, essential community services grind to a halt—water utilities stop billing and monitoring, emergency response coordination falters, and payroll processing fails. Worse still, legacy systems lack the advanced disaster recovery tools that modern solutions provide. Recovery can take weeks or months—if recovery is even possible. In many cases, the technology is so outdated that a full emergency system replacement becomes the only option, draining public funds and overwhelming already stretched teams.
Many local government organizations underestimate the true cost of cybersecurity vulnerabilities in outdated software. The financial impact of an attack goes far beyond the ransom demand itself—data restoration, legal fees, regulatory fines, and reputational damage all contribute to the overall financial burden. For example, the 2019 Baltimore ransomware attack, which exploited weaknesses in outdated municipal systems, cost the city over $18 million in recovery expenses and lost revenue.
The indirect costs of outdated software vulnerabilities also extend to lost productivity and public trust. When essential services are disrupted due to a cyberattack, residents and businesses suffer. A delayed or inadequate response to such threats can lead to widespread frustration, decreased confidence in government institutions, and even legal liabilities if personal data is compromised.
Local governments often think they are saving money by postponing software upgrades, but, in reality, they are exposing themselves to exponentially greater financial risks in the long run. Today, we’re exploring the hidden cybersecurity costs of outdated software and why local government organizations like yours must seriously evaluate whether keeping legacy systems is worth the risk.
The Staggering Cost of Cybersecurity Breaches
In the United States, the average cost of a data breach has risen to $9.36 million, reflecting the increasing sophistication of cyberattacks and the sensitivity of data held by organizations, including local governments. Between 2014 and 2022, data breaches at local, state, and federal agencies cost governments $26 billion, according to a report by Comparitech, a consumer-aid website that researches cybersecurity breaches. The report found that 175 million records were affected in 822 incidents nationwide across all levels of government. Local governments, often targeted due to outdated systems, face crippling ransomware attacks that disrupt essential services, expose sensitive data, and result in steep ransom demands. Many municipalities, faced with limited cybersecurity resources, are forced to pay millions to regain access to their systems or spend weeks restoring operations.
The 2019 Baltimore ransomware attack is just one of many well-known examples where the city’s computer systems were infected with RobbinHood ransomware, a form of extortionware that encrypts files and demands payment in Bitcoin. Exploiting unpatched Microsoft vulnerabilities, the attack caused widespread disruption to Baltimore’s email systems, billing operations, and real estate transactions, delaying services for residents and businesses. Refusing to pay 13 Bitcoin (around $76,000 at the time), Baltimore chose to rebuild its systems from backups. The attack ultimately cost the city an estimated $18 million in recovery expenses and lost revenue.
Cyberattacks have only grown more sophisticated since. In July 2024, Columbus, Ohio, suffered a significant ransomware attack that compromised the personal data of 500,000 individuals. Attributed to the Rhysida ransomware group, the attack led to major operational disruptions and raised concerns about municipal cybersecurity preparedness. Hackers accessed 6.5 terabytes (TB) of sensitive data, including names, addresses, dates of birth, Social Security numbers, bank account details, and driver’s license information. The City Council allocated up to $7 million to cover expenses related to the breach, including system restoration, legal fees, and protective measures for affected residents.
Beyond the immediate financial impact of cyberattacks, failing to comply with strict cybersecurity regulations such as NIST (National Institute of Standards and Technology), CJIS (Criminal Justice Information Services), and HIPAA (Health Insurance Portability and Accountability Act) can have severe financial and operational consequences. Regulatory fines are among the most immediate penalties. For example, non-compliance with HIPAA can result in fines of up to $1.9 million per violation per year, while CJIS non-compliance can lead to agencies losing access to essential federal databases. Similarly, failing to meet NIST cybersecurity standards, which many federal and state grants require, could make municipalities ineligible for critical funding, straining already tight budgets. These fines and funding losses can quickly add up, forcing local governments to divert resources from essential public services to cover compliance failures.
Cybersecurity non-compliance can also lead to lawsuits and class-action legal battles if citizen data is exposed due to inadequate protections. When municipalities fail to safeguard personally identifiable information (PII), such as tax records, medical histories, and law enforcement case files, they become liable for negligence claims, breach-of-privacy lawsuits, and even federal investigations. The resulting legal fees and settlement costs can be astronomical, as seen in cases where data breaches have cost local governments millions in restitution payments to affected residents.
Additionally, manual security patching and system maintenance on outdated software consume valuable IT resources, diverting funds that could be used for cybersecurity modernization and digital transformation initiatives. Unlike modern cloud-based solutions, which receive automated updates and real-time threat monitoring, legacy systems require frequent hands-on intervention to address vulnerabilities. This ongoing maintenance drains time and resources, pulling IT teams away from proactive cybersecurity strategies. Older software also requires specialized expertise, often leading municipalities to retain expensive third-party consultants or develop custom workarounds to keep outdated systems operational.
Legacy infrastructure also lacks interoperability, making it difficult to integrate with modern cybersecurity tools, identity management solutions, and compliance frameworks. This fragmented approach forces governments to adopt piecemeal security solutions, each adding to overall IT costs without providing a long-term fix. Over time, municipalities find themselves trapped in a cycle of paying for temporary solutions instead of investing in a scalable, secure system that evolves with emerging cybersecurity threats.
So, what exactly makes legacy systems a hacker’s playground?
Inherent Software Vulnerabilities
Legacy software solutions are inherently more vulnerable than modern, cloud-based SaaS platforms. One of the most significant security gaps is their inability to support multi-factor authentication (MFA), a critical defense against phishing attacks and credential theft. Without MFA, a single compromised password can grant cybercriminals unrestricted access to municipal databases, financial systems, and citizen records. Additionally, older applications often rely on outdated encryption protocols such as SHA-1 and TLS 1.0, which are vulnerable to modern decryption techniques. Modern standards like AES-256 and TLS 1.3 provide significantly stronger data protection, but many legacy systems cannot be upgraded to support them, leaving sensitive government information exposed to potential breaches.
Another significant weakness of legacy software is its vulnerability to ransomware attacks due to outdated backup methods. Traditional backups can be easily encrypted or deleted by ransomware, making data recovery difficult or even impossible. In contrast, modern immutable backup solutions prevent modification, ensuring that critical data remains protected even during an attack. Additionally, legacy systems often lack support for secure API communications, making it difficult to integrate with modern third-party services while maintaining cybersecurity best practices. Without protocols like OAuth 2.0, OpenID Connect, and JSON Web Tokens (JWT), legacy software is more susceptible to unauthorized access, API hijacking, and data breaches.
Missing or Delayed Security Patches
Another significant security vulnerability in legacy systems is the lack of regular patching and updates, exposing them to known exploits. Software vendors routinely release patches to fix security flaws, enhance performance, and address newly discovered threats. However, older software that has reached its end of life (EOL) no longer receives these critical updates, making it highly susceptible to cyberattacks. Organizations running unsupported software, such as outdated Windows Server versions, legacy ERP systems, or old database platforms, remain vulnerable to exploits that modern systems have already mitigated.
Even when legacy software is still technically supported, manual patching processes create security gaps. Many older systems do not support automated patch management, requiring IT teams to track and apply updates manually. This often leads to delays in implementing security fixes, as updates may be deprioritized due to concerns about system stability, compatibility issues, or lack of IT resources. Cybercriminals frequently exploit these unpatched vulnerabilities—such as the EternalBlue exploit, which was used in the WannaCry ransomware attack—to infiltrate networks and compromise sensitive data.
Legacy systems may also be deeply embedded in critical infrastructure, making patching difficult or even impossible without causing operational disruptions. Organizations often continue using outdated systems because upgrading is costly or complex. As a result, they become easy targets for cyberattacks, with attackers specifically scanning for known vulnerabilities in unpatched systems. Without continuous security updates, legacy software remains a persistent weak point.
Incompatibility with Modern Security Tools
Legacy systems also pose a major security risk because they lack compatibility with modern cybersecurity tools designed to detect, prevent, and respond to evolving threats. For example, many outdated systems do not support Security Information and Event Management (SIEM) platforms, which collect and analyze real-time security logs to identify suspicious activity across an organization’s network. Without SIEM integration, municipalities have limited visibility into unauthorized access attempts, phishing attacks, and credential theft, making it easier for cybercriminals to exploit vulnerabilities. Additionally, legacy software often cannot connect with Intrusion Detection and Prevention Systems (IDPS), which actively monitor traffic for signs of cyberattacks and automatically take action to block malicious activity. This lack of integration creates security blind spots, leaving government agencies without the necessary tools to identify and mitigate cyber threats proactively.
Another critical limitation of legacy infrastructure is its incompatibility with AI-driven security solutions such as Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR). These tools increasingly incorporate artificial intelligence (AI) and machine learning (ML) to detect abnormal behavior, isolate threats, and prevent zero-day attacks before they can cause damage. However, outdated software lacks the processing power, logging capabilities, and real-time data-sharing features needed to support these advanced security measures. Without EDR/XDR, local governments are left vulnerable to sophisticated malware, ransomware, and automated cyberattacks that modern security tools are specifically designed to stop. Additionally, older systems often cannot integrate with Threat Intelligence Platforms (TIPs), which provide real-time updates on emerging cybersecurity risks. Without access to the latest threat intelligence, municipalities struggle to adapt their defenses, making them easy targets for attackers.
Cloud security is another area where legacy software falls short, as many outdated systems do not support Cloud Access Security Brokers (CASB)—critical tools for enforcing data loss prevention (DLP) and access control policies in cloud environments. Without CASB, municipalities lack the ability to monitor and restrict sensitive data movement across cloud applications, increasing the risk of data breaches. Additionally, legacy systems often lack support for Zero Trust security frameworks, which rely on role-based access controls (RBAC), continuous authentication, and device verification to ensure that only authorized users can access critical systems. Without these modern security measures, attackers who breach an outdated system can move laterally across the network, escalate privileges, and exfiltrate sensitive data without detection.
Increased Risk of Attacks
Hackers specifically target legacy systems because they are easier to exploit due to outdated security measures and unpatched vulnerabilities. Many older systems have known security flaws that cybercriminals can easily find in public vulnerability databases, such as the Common Vulnerabilities and Exposures (CVE) list. Since many legacy applications no longer receive security patches or vendor support, attackers can use automated tools to scan networks and identify systems running outdated software. Exploiting these weaknesses allows them to launch ransomware attacks, data breaches, and other malicious activities with minimal effort.
Another reason hackers focus on legacy systems is their critical role in government agencies, utilities, and financial institutions. Cybercriminals know that shutting down essential public services—such as emergency response systems, water utilities, or payroll operations—puts enormous pressure on organizations to pay ransoms or comply with extortion demands. High-profile ransomware attacks like WannaCry and NotPetya specifically targeted outdated Windows systems, causing billions in damages worldwide.
Lack of Compliance with Government Regulations
Legacy software makes it difficult—if not impossible—for government agencies to comply with modern cybersecurity and data protection regulations. Many frameworks, such as NIST (National Institute of Standards and Technology), CJIS (Criminal Justice Information Services), and HIPAA (Health Insurance Portability and Accountability Act), require agencies to implement regular security updates, strong encryption, access controls, and real-time monitoring. However, outdated systems often lack vendor support, meaning they do not receive critical security patches needed to fix vulnerabilities, leaving agencies non-compliant and exposed to cyber threats.
Another major compliance challenge is data protection and encryption standards. Many older systems use weak encryption protocols (such as SHA-1 or TLS 1.0), which no longer meet regulatory requirements for safeguarding sensitive citizen data. Agencies that fail to update their encryption methods risk fines, legal action, and loss of public trust. Additionally, legacy platforms often lack proper audit logging and real-time threat detection, making it challenging to track unauthorized access and detect data breaches—a requirement in frameworks like CJIS that mandate strict security monitoring and incident response protocols.
The risks and costs associated with outdated software in local government organizations are undeniable. From severe security vulnerabilities to compliance failures and financial repercussions, legacy systems are a growing liability. Cyberattacks are becoming more sophisticated, targeting known weaknesses in older infrastructure, and municipalities cannot afford to remain complacent. The fallout from ransomware attacks, data breaches, and operational disruptions extends far beyond financial losses—it erodes public trust, disrupts essential services, and places sensitive citizen data at risk.
While modernizing IT infrastructure may seem costly, the long-term savings in security, efficiency, and compliance far outweigh the risks of maintaining outdated systems. Upgrading to cloud-based SaaS solutions can significantly enhance cybersecurity resilience. Proactive investment in modern, scalable technology ensures local governments can protect their communities while meeting evolving regulatory standards.
By prioritizing cybersecurity modernization, municipalities can safeguard their operations, maintain public trust, and ensure the uninterrupted delivery of critical services. The time to act is now—before outdated software becomes the weakest link in government security.
