The recently announced UUSEC WAF (Web Application Firewall) has sparked significant debate within the developer community, with users raising serious questions about its licensing, transparency, and security implications. While the product markets itself as a free, high-performance web application firewall with advanced AI capabilities, community members have identified several concerning aspects that potential users should be aware of.

License Misrepresentation Issues
One of the primary concerns raised by community members is the misleading characterization of UUSEC WAF as open source. A careful examination of the license reveals significant usage restrictions that contradict open source principles. As one commenter pointed out, the license sets limits on use and does not seem to provide open modification nor distribution, which would disqualify it from being considered truly open source by widely accepted standards.
Further investigation suggests the product may not even qualify as source-available. The GitHub repository appears to contain primarily documentation, Lua scripts without clear context, a small PHP module, and a pre-compiled binary. The core functionality seems to be delivered through a Docker image hosted on Huawei Cloud rather than through transparent, reviewable code.
Security and Trust Concerns
The reliance on Docker images hosted on Huawei Cloud has raised red flags among security-conscious developers. Several commenters expressed caution about the origins of the software, with some speculating about potential security implications. The lack of transparency regarding what's actually in the Docker images compounds these concerns.
I would take this as two things at once, from personal opinion: There is probably a PRC backdoor somewhere in this; This is probably very high quality software
This sentiment captures the conflicted perspective many have about the product - acknowledging the potential technical quality while remaining wary of security implications.
Questionable Marketing Tactics
Community members have also highlighted concerning marketing practices associated with UUSEC WAF. There are reports of promotional ad issues being opened on unrelated GitHub repositories, which has damaged trust in the project. Additionally, some commenters noted that certain responses in discussion threads appear to be generated by AI rather than genuine user experiences, further eroding credibility.
The comparative performance metrics provided in the documentation - showing UUSEC WAF outperforming competitors like ModSecurity and CloudFlare - have also been questioned. One commenter specifically asked about the methodology behind these benchmarks, highlighting the lack of transparency in how these comparisons were conducted.
Alternative Options
For those seeking genuine open source WAF solutions, community members have suggested alternatives such as Coraza, which is available under the Apache license. Unlike UUSEC WAF, Coraza can be embedded as a library, used as an nginx or caddy plugin, or run standalone, offering greater flexibility and transparency.
In an era where security costs are rising, as noted by one commenter concerned about increasing prices from providers like Akamai and Cloudfront, the appeal of a truly free and open solution is understandable. However, the community discussion makes it clear that thorough vetting of security tools remains essential, particularly when claims of being free and open source may not align with reality.
While UUSEC WAF advertises impressive technical capabilities, including machine learning for threat detection and semantic analysis engines, the concerns raised by the developer community suggest potential users should approach with caution and conduct thorough due diligence before implementation.
