Featured Reviews

MS
Associate Director IT Operations at Procento
Single-pane management has simplified firewall control and has improved risk mitigation
I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.
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.
