Public Sector Cybersecurity
for Controlled Modernization
Protect mission-critical government applications while maintaining compliance across agencies, contractors, and development teams.
Empower Your
Developers
A developer friendly experience eliminates common security tool frustrations, making developers want to participate in your application security program.
Compliance and Audit Pressure Across Every Program
FedRAMP, FISMA, and NIST require end-to-end traceability and evidence. Gaps don’t just create risk — they halt deployments, delay funding, and generate findings that take months to remediate under controlled change processes.
Security Breaks at the Legacy-to-Cloud Boundary
Legacy mission systems and modern cloud services run side by side across most agencies. Without consistent coverage across both, security gaps emerge exactly where the two environments connect — and that’s where adversaries look first.
Contractor Ecosystems Make Standards Drift
Government delivery relies heavily on contractor teams with their own tools, processes, and priorities. Maintaining consistent security requirements across this fragmented ecosystem requires a platform that enforces standards regardless of who’s writing the code.
Supply Chain Risk Across Citizen-Facing Ecosystems
Citizen apps, public APIs, and vendor components add third-party risk that’s hard to track and often missed until it impacts production. A single compromised dependency in a public-facing service has consequences that extend far beyond the IT department.
Application Security That Prioritizes What Matters
Checkmarx One ASPM closes visibility gaps, eliminates redundant triage, and enables smarter prioritization with risk orchestration for faster, more efficient remediation.
End-To-End Risk Coverage
Connect vulnerabilities from source to runtime by integrating findings from Checkmarx, third-party tools, and CNAPPs into one unified view of risk.
Connect to Your Dev Ecosystem
Integrate with cloud tools, ticketing systems, and any IDE — bringing full ASPM context and best-fix-location guidance into existing workflows.
Context-Enriched Risk Scoring
Powered by Checkmarx Zero, blend exploitability, reachability, fixability, and runtime exposure into one aggregated risk score so you can prioritize and act based on real business risk.

Frequently Asked Questions
Checkmarx centralizes posture reporting, evidence, and consistent policy enforcement across internal teams and contractors – helping agencies maintain accountability across fragmented delivery environments. A single platform enforces the same security standards regardless of which contractor is writing the code, making it possible to demonstrate compliance across the entire program delivery chain.
Yes. Checkmarx provides SAST, SCA, DAST, and API Security coverage across long-lived mission systems and newer citizen-facing services — so agencies can modernize without losing control. Coverage is consistent whether the application is a decades-old mainframe system or a newly deployed cloud-native citizen portal.
Checkmarx helps teams preserve evidence, traceability, and posture reporting across programs so audit preparation does not depend on manual collection or inconsistent process. ASPM maintains a continuous, automated record of what was scanned, what was found, and how findings were resolved — giving agencies the documentation chain that FedRAMP, FISMA, and NIST reviews require.
Early detection, consistent policy enforcement, and predictable remediation workflows help teams reduce late surprises that can delay fixed timelines tied to funding or public service requirements. Catching vulnerabilities before they enter formal change control — rather than after — eliminates the most costly kind of rework in government delivery environments.
