Tech Lead and Senior DevOps Engineer at a tech vendor with 10,001+ employees
Advanced automation and powerful traffic controls have improved application security
HTTP/2 and HTTP/3 support is something that definitely could be improved in F5 BIG-IP [Private Offer Only]. I mean HTTP/2 and HTTP/3 protocol support, as well as security for them too. For F5 BIG-IP [Private Offer Only] to have better support for them would include load balancing, but also better WAF (Web Application Firewall) support for these two protocols. Improving the mentioned HTTP/2 and HTTP/3 support and the GUI would be beneficial. If they improve those things and add machine learning and AI, I want it to have some kind of AI on the box because everyone is going to AI, and they have to add some AI security to be able to check the traffic using AI models. HTTP/2 and HTTP/3 protocol support, AI, the GUI to be changed, and inline AI where the device downloads pre-built AI models from a SaaS cloud to check the traffic for security is something I think is very needed because using AI models as a replacement for signatures will be better. I think WAF signatures are a thing of the past. I would also like to see HTTP/2 and HTTP/3 in the future as additional features, and anything else I would improve would definitely include HTTP/2 and HTTP/3.

Team collaboration has improved and project tracking is clearer but downtime still causes disruption
I think there are some parts of Lark that have not been translated, and sometimes there is a glitch where the product still uses Chinese words. Lark occasionally experiences downtime, and during those times, we usually use WhatsApp for communication and coordination, which can be frustrating. Regarding Lark's AI capabilities, I believe they are good in terms of governance and security. I think there is still room for improvement regarding the accuracy and reliability of Lark's AI output.
