Secure Software for the Public Sector

For U.S. State, Local, Tribal, and Territorial (SLTT) government organizations, most cyber risk is created before an attacker ever takes action. Insecure defaults, inconsistent configurations, and fragmented responsibility across agencies and operators introduce vulnerabilities that persist for years. While guidance and standards are abundant, implementation often fails to scale across real‑world public‑sector environments.

Secure by Design shifts cybersecurity upstream, ensuring systems start secure from day one and remain resilient through shared standards, trusted baselines, and collective defense.

SLTT governments face constant pressure to modernize securely. At CIS, Secure by Design is the foundation of every solution we build. The CIS Benchmarks, CIS Benchmarks®, CIS Critical Security Controls®, CIS SecureSuite®, and CIS Hardened Images® help agencies adopt secure configurations, reduce risk by default, and strengthen compliance at every stage of their cybersecurity journey.

Security Should be Built in–Not Added On

Secure by Design begins where security truly starts: at build time.

Public‑sector teams need software and platforms that are safe, secure, and consistent by default– without requiring deep security expertise, extensive staffing, or custom hardening work.. Insecure defaults create risk long before deployment, and inconsistent configurations across agencies amplify that risk.

When systems are secure by default and supported by common standards, public‑sector organizations can:

  • Reduce entire classes of preventable attacks
  • Lower operational and remediation burden on small, resource‑constrained teams
  • Improve resilience without relying on constant firefighting
  • Scale security consistently across agencies, programs, and jurisdictions

Secure by Design focuses on how software is built. Secure by Default focuses on how it is delivered and deployed. Both are essential for public‑sector resilience.

The Reality: Security Breaks Down at Scale

Public‑sector teams aren't short on guidance—NIST, CISA, CIS, and state-level requirements offer plenty. The challenge is operationalizing that guidance across diverse, distributed environments.

Common pain points include:

  • Guidance that doesn’t translate into operations: Best practices exist, but applying them across agencies, pipelines, and releases often doesn’t scale.
  • Fragmented and conflicting standards: Multiple frameworks and requirements create confusion, gaps, and duplicated work
  • Security added too late: Hardening begins after deployment—when vulnerabilities may already exposed.
  • Inherited risk: Agencies must manage systems, configurations, and defaults they didn’t choose and can’t fully redesign.

The result is a cybersecurity posture that depends on manual fixes, human oversight, and reactive monitoring, rather than secure architecture.

A Better Model: Secure by Design for SLTTs

Secure by Design flips the model. Instead of reacting to weaknesses, systems begin secure and remain secure throughout their lifecycle.

When platforms and applications are built on shared, trusted, and government-validated standards:

  • Many routine and high‑frequency attack vectors are eliminated upfront, long before they can be exploited.
  • Standardized configurations stay consistent, reducing drift and easing the day‑to‑day burden on IT and security teams.
  • Staff can redirect time and resources from preventable fixes to higher‑value mission and community priorities.
  • Security practices become consistent, measurable, and easier to apply across agencies and jurisdictions.
