Standardized our Java estate and have reduced licensing costs while maintaining strong support
Azul Zulu's ability to allow us to standardize our Java estate on a single and well-supported platform stands out as one of its best features. This standardization simplifies our compliance audits and ensures all our applications receive timely security updates.Azul Zulu positively impacts our organization by providing a platform that allows us to standardize Java on a well-supported platform. Without the high cost associated with other proprietary vendors, Azul Zulu provides an excellent platform for running our applications.

Caching and reverse proxy have boosted performance and improved secure web and mail access
I think Squid Proxy Cache Server can be improved by having a nice front-end, one similar to Blue Coat for access management, view management, and direct configuration instead of doing it all through the CLI. It's best to have everything done through the GUI, which is what I think can improve the product. I don't want to implement third-party GUIs on Squid Proxy Cache Server. So that's what would be on my wish list—that Squid Proxy Cache Server by itself provides a GUI, which will give more confidence to users. I haven't actually used AI with Squid Proxy Cache Server, but I think it might be very interesting to have the AI capability built-in. However, I do think we need some GPU or something to boost the performance on Squid Proxy Cache Server as natively running. I think we need to add some GPU cards so that it works more natively with AI. I don't have experience using AI features yet, but I think it would be great if it could do some live scanning of the websites that are getting blocked on a daily basis and perform some sampling analysis. Especially in the case of reverse proxy, if there are any attacks happening, it would be beneficial if it scrapes through its own log files and provides some nice dashboards showing where the attacks are coming from. That would be really great to have as a handy troubleshooting tool. One more feature I would ask for is if AI can provide the best possible configuration and do a review of Squid Proxy Cache Server just to make sure that no other ports or anything by default are missed in configuration. It would also be great if the proxy server acts as a load balancer in a cluster mode that shares the cache, and the configuration is best set.

"Squid Proxy Cache Server positively impacts my organization because I can filter the internet content that users can access."
"Squid Proxy Cache Server had a positive impact on my organization by helping with productivity, as it ensured quality of access and improved the quality and performance of my staff greatly."
"Before, we used Blue Coat Proxy, Cyberoam Proxy, Forcepoint, and other solutions, and the reason we switched to Squid Proxy Cache Server is cost, because those professional proxy solutions have huge yearly cost involvement, and currently with Squid Proxy Cache Server, we are using it at no cost."
"What I appreciate the most about Squid Proxy Cache Server is that both of its features are very beneficial for any IT company, whether it should be a media company, a finance company, or any other sector."
"The overall main benefits I experienced from using Squid Proxy Cache Server are the ability to control employee web browsing."

"I believe that Squid Proxy Cache Server could see improvements with updates to incorporate the latest kernel."
"I think Squid Proxy Cache Server can be improved by having a nice front-end, one similar to Blue Coat for access management, view management, and direct configuration instead of doing it all through the CLI."
