Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
Ashutosh Jha - PeerSpot reviewer
Project Engineer at IT Solution
Robust protection has blocked external threats and provides clear visibility into user activity
Sophos Firewall offers multiple features, including IPS, IDS, ATP, NDR, XOps, web protection, application protection, web server protection, and many more. Out of all those features, I find web protection and application protection to be very helpful and valuable in my daily work. Sophos Firewall has positively impacted my organization by preventing outside threats, allowing me to easily monitor my users, and configuring any rule for any user regarding what they need to use and what I am restricting for the particular user. I can share that it has improved productivity because if anyone could ransom my network, they could demand money to decrypt the files, thus saving us money, time, and providing reliability.
