How does Apache Tomcat NES compare to upgrading to newer Tomcat versions?

Upgrading to newer Tomcat versions typically costs 3-5x more than implementing NES, requires 3-6 months of development time, and carries significant risk of breaking complex configurations and integrations. NES provides immediate security for your servlet container while allowing you to plan upgrades strategically rather than reactively.

How are Spring applications affected by Tomcat vulnerabilities?

Spring Boot applications may be affected if they enable the default servlet, use file-based session persistence, or have deserialization vulnerabilities. Since Spring applications typically run on Tomcat, vulnerabilities in the servlet container can compromise even well-secured Spring code. NES protects the Tomcat foundation that your Spring applications rely on.

What happens if we do nothing now that our Tomcat version is end-of-life?

Without security patches, your Tomcat applications face increasing vulnerabilities in servlet processing, JSP execution, and connector handling. Critical vulnerabilities like CVE-2025-24813 (CVSS 9.8) are already being actively exploited in the wild, targeting organizations in the U.S., Japan, India, South Korea, and Mexico.

Critical Challenges We Solve

Evolving Security Threats

Recent vulnerabilities can target servlet processing and can lead to remote code execution. NES delivers timely patches for these emerging threats that would otherwise remain unaddressed in end-of-life Tomcat versions.

Spring Dependencies

Spring Boot applications can be particularly vulnerable when running on outdated Tomcat versions, creating compound security risks. NES addresses vulnerabilities at the servlet container level, protecting your Spring applications from underlying threats.

Compliance Violations

Running unsupported software increasingly results in audit findings and regulatory penalties. NES helps maintain compliance with SOC 2, PCI DSS, HIPAA, and FedRAMP by providing ongoing security updates and documentation.
