Secure drop-in replacements for CometD version 5, 6, 7
NEVER-ENDING SUPPORT FOR
CometD
Legacy CometD versions still function after support ends — but that's not good enough for internal SLAs, CVE disclosures, and security audits.
Never-Ending Support (NES) for CometD keeps you compliant, secure, and audit-ready without an unplanned migration or risky patchwork.
Secure Your Real-Time Messaging Infrastructure
Never-Ending Support (NES) for CometD provides extended security support for your Bayeux protocol implementations and WebSocket/long-polling infrastructure without forcing migration from proven, production-tested versions.
Why NES for CometD Matters
End-of-life CometD versions expose your real-time messaging layer to:
Protocol-level vulnerabilities in Bayeux message handling
WebSocket security gaps affecting bidirectional communication
Transport layer exploits in long-polling fallbacks
NES delivers backported security patches for your CometD server and client libraries, maintaining compliance while you control migration timelines.
Real-World CometD Deployments We Secure
High-Volume Messaging Systems
Protect trading platforms, gaming servers, and collaboration tools handling millions of concurrent connections where CometD version changes risk message delivery guarantees
Multi-Transport Deployments
Secure complex implementations using WebSocket with HTTP long-polling fallbacks across diverse client environments and network conditions.
Clustered CometD Architectures
Maintain security across distributed Oort clustering setups without risking message routing disruptions or session affinity breaks.
Loved by Our Customers
From the very first point of contact, working with HeroDevs has been an exceptional experience...The option to install EOL Support, rather than undertaking a full internal migration, has saved us significant time, money, and frustrations.”
The Growing Security Gap
When CometD 5, 6, and 7 reached end-of-support, security patches for managed dependencies stopped, creating a widening vulnerability gap for organizations still using these versions. We maintain stability with CometD and the ecosystem by following the same proven dependency management practices used by CometD maintainers during official support. This means comprehensive testing and validation across the entire dependency tree.
