How Can State and Local Government Institutions Strengthen Cybersecurity in 2026?
In 2026, state and local governments must adopt automation, Zero Trust, and certificate lifecycle management to strengthen cybersecurity resilience.
With limited budgets, understaffed IT teams, and outdated infrastructure, state and local governments are increasingly vulnerable to cyberattacks of all kinds. High-profile incidents in recent years demonstrate the real-world impact, from service disruptions to data breaches. Strengthening cybersecurity in 2026 requires a strategic shift toward automation, Zero Trust, and especially automated certificate lifecycle management (CLM), which is rapidly becoming essential.
When these attacks are successful, the results can be truly devastating: Crucial services may become unavailable, and the community's highly sensitive data could be exposed. Ransomware and man-in-the-middle attacks remain alarming possibilities. With such high stakes, it's clear that government agencies must prioritize cybersecurity resilience while taking advantage of resources that bolster security and modernize governance.
A key tool in this effort to strengthen cyber resilience is automated certificate lifecycle management. This article highlights forward-thinking cybersecurity best practices for 2026 and beyond, showing how automation can help state and local governments build stronger, more resilient systems.
Rising cyber risks in 2026
State and local governments have long been uniquely vulnerable to cyberattacks due to structural limitations and under-resourced IT environments. In 2026, these risks are intensifying as public sector networks continue to expand their digital footprint. Hybrid work models and increased use of remote access tools are rapidly expanding the attack surface, exposing the limitations of antiquated and manual systems.
Without automation and strong identity controls, digital certificate, credential, and device sprawl are becoming unmanageable.
This sprawl is further complicated by the upcoming reduction in certificate validity periods. By 2029, SSL/TLS certificates will have a lifespan of only 47 days. This will pose significant challenges for IT teams including maintaining timely renewals and meeting strict compliance requirements.
The reality of these risks was underscored in July 2025, when Microsoft SharePoint servers were targeted in attacks affecting more than 90 state and local entities. Although a spokesperson from the U.S. Department of Energy clarifies that "attackers were quickly identified, and the impact was minimal,” and that no sensitive information was leaked, the what-ifs of this situation still raise alarm and indicate the need for robust information security measures that better address a wider range of vulnerabilities.
What cybersecurity challenges do state and local governments face today?
Modernization efforts across the public sector have led many agencies to adopt cloud platforms, hybrid infrastructures, and remote access tools. While these updates offer clear benefits, they also introduce new risks when layered over outdated legacy systems. The resulting mix creates operational silos and fragmented oversight that make it difficult to maintain consistent security standards.
An ongoing reliance on manual systems adds to this complexity. IT teams are often forced to track expirations, respond to outages, and manage certificate renewals without centralized visibility or automation. This reactive approach consumes valuable time and increases the risk of costly downtime. Forrester research shows that outages tied to expired certificates can cost organizations thousands of dollars per minute, a risk few public institutions can afford.
Meanwhile, evolving compliance mandates from both state and federal regulators continue to raise the bar. From encryption standards in Ohio to breach notification timelines in New York and Maryland, agencies must now navigate a patchwork of security requirements. At the federal level, the executive order Sustaining Select Efforts to Strengthen the Nation’s Cybersecurity reinforces the urgency of implementing encryption protocols and Zero Trust principles across government systems.
Meeting these challenges requires a shift toward proactive cybersecurity, supported by automation, improved visibility, and alignment with best-practice frameworks.
What are the cybersecurity best practices for state and local governments in 2026?
Amid escalating cybersecurity risks and still-limited resources, state and local governments must work smarter, not harder. In 2026, this means moving away from ad-hoc, manual processes and focusing on Zero Trust, automation, and full lifecycle control. The heightened demands of the coming year will force state and local government agencies to prioritize digital resilience, moving beyond reactive security practices and making the most of automated certificate lifecycle management.
Assess risks regularly
Weaknesses cannot be properly addressed until they are identified and understood. This means thoroughly examining local government cybersecurity posture to reveal gaps that could potentially be exploited. Focus on critical infrastructure such as servers, email systems, applications that serve community members, and remote access channels. Include regular reviews of network and endpoint security to find vulnerabilities before they’re exploited.
Build a Zero Trust foundation
As threats increasingly originate from within trusted networks, traditional perimeter defenses are no longer enough. Zero Trust is now the gold standard for digital security. This does away with inherent trust, instead suggesting that any user, device, or application could be potentially compromised.
That’s why identity-based access controls are now the cornerstone of modern cybersecurity, with every identity verified before access is granted. Digital certificates play an important role in identity verification, enforcing least-privilege permissions that limit users to the level of access needed to perform critical tasks.
Strengthen visibility with automated CLM
Automated certificate lifecycle management will be crucial as certificate lifespans continue to shrink. This provides agencies their best chance of keeping up with the accelerating pace of renewals. With a centralized inventory of certificates, credentials, and endpoints, visibility improves across all systems. Automated certificate discovery enables a full inventory of assets so that they can be properly managed.
This effort extends to issuance, deployment, and even discovery, limiting the likelihood of gaps or outages. Offering easy-to-use dashboards, these systems replace confusing spreadsheets and manual tracking tools with automated, centralized lifecycle management. This will make it far easier to adapt to 47-day lifespans, for, depending on validation, automated deployments and renewals take a few short minutes to complete.
Secure cloud and hybrid environments
An increased reliance on cloud applications has sparked the need for extended protection to address a much larger attack surface. In addition to securing on-premises systems, today's state and local government agencies must also deal with cloud-hosted workloads and even Internet of Things (IoT) devices. Consistent encryption is key to maintaining trust across this vast digital environment. This is achieved not only through automation, but also, through strong certificate policies and continuous monitoring of remote access, mobile users, and third-party integrations.
Focus on compliance, resilience, and third-party risk
Compliance offers a valuable foundation to address cybersecurity challenges. Use established frameworks from authorities such as the National Institute of Standards and Technology (NIST) and the Center for Internet Security (CIS) to standardize security controls and bolster governance. Building redundancy and recovery plans ensures essential services can continue during an incident.
Keep in mind that high compliance expectations should also apply to third-party vendors, as these can introduce significant risks into otherwise well-protected systems. From IT managed service providers to payment processors, many vendors and contractors require vetting, but the added effort can improve overall resilience.
Modernize and secure legacy systems
Legacy systems are often the weakest link in government infrastructure, creating security gaps that attackers can easily exploit. These systems eventually need to be replaced, but this transition can feel overwhelming. Thankfully, it is possible to augment these solutions with contemporary tools that improve both security and performance.
Begin by highlighting outdated software or devices that no longer receive sufficient support. If certain legacy systems cannot yet be upgraded, they should at least be segmented or isolated to limit exposure. Systems linked to critical operations (such as finance or HR) may require priority upgrades.
Invest in cybersecurity awareness training and staffing
Human talent remains a critical part of any cybersecurity challenge, but even knowledgeable IT staff members may struggle to keep up with evolving standards and practices. Regular training and cybersecurity awareness programs are needed for administrators and contractors alike. Agencies should hold tabletop exercises and update incident response playbooks at least twice a year to keep teams sharp.
Training for IT and network teams should encompass cutting-edge threat detection and certificate management strategies. Prioritize active cybersecurity skill development with exercises and simulations that help staff put incident response strategies into action.
Training will only go so far if staffing needs remain unmet. Agencies that are already stretched thin may rely on grants or partnerships to expand cybersecurity headcount. Shared-service models across municipalities can also help pool resources and extend cybersecurity coverage more efficiently.
How automation supports long-term cybersecurity goals
Automation has become the only scalable way to manage the growing complexity of digital certificate lifecycles. As public SSL/TLS certificate lifespans shrink from 398 days to 47, manual processes quickly become unsustainable. Automated certificate lifecycle management platforms like Sectigo Certificate Manager help eliminate human error, reduce the administrative burden on IT teams, and prevent service outages caused by missed renewals or misconfigurations.
Looking ahead, automation plays a critical role in achieving crypto agility. With quantum computing on the horizon, organizations must prepare for a future in which classical cryptographic algorithms will no longer provide sufficient protection. Sectigo supports this transition through hybrid certificates and post-quantum cryptographic (PQC) solutions that combine traditional and quantum-resistant encryption methods. These innovations ensure that government agencies can begin migrating sensitive systems today while maintaining compatibility with current environments.
By automating certificate deployment, renewal, and replacement, and by preparing for the demands of the quantum era, state and local governments can protect sensitive data, maintain operational continuity, and future-proof their cybersecurity strategies.
