I enjoy the combination of an intuitive graphical interface and also a traditional shell command line environment for more advanced administration. The option to configure policies in a graphical environment is very easy to understand and also simple to teach someone else unfamiliar with the product.

I can delegate more simple and routine tasks to other administrators and I don’t have to be the “Firewall” guy all the time, but the graphical interface always has room for improvement.
What is most valuable?
How has it helped my organization?
It’s much easier to share administration tasks with more people. Due to the flexibility and ease of certain features, I can delegate more simple and routine tasks to other administrators and I don’t have to be the “Firewall” guy all the time.
What needs improvement?
I think the graphical interface always has room for improvement. I would like to see more attention put towards the logging functions as well.
For how long have I used the solution?
I worked with this solution daily for over 12 months.

872,869 professionals have used our research since 2012.
What do I think about the stability of the solution?
I encountered several strange issues in v5.0 (and earlier) OS versions. Strange anomalies like random reloads, VPN instability and unexplained policy changes. However, all of these issues were resolved in v5.2.
How are customer service and support?
I always had great experiences with Fortinet. I worked with them several times to resolve configuration issues and process RMA’s on failed equipment, which was rare.
Which solution did I use previously and why did I switch?
I’ve personally used Cisco ASA and PIX architecture and after using Fortinet, I always prefer FortiGate products in terms of functionality and ease of use. I recommend these to clients looking for a firewall solution.
How was the initial setup?
Usually always simple and straight forward. I can get a client up and running with most standard policies and inbound/outbound control in a single day and make adjustments as needed. I can usually preconfigure Fortinet products and send them out for install.
What about the implementation team?
I always implemented via in-house. I think the most important advice is to always test new configurations in the lab especially, when upgrading firmware.
What was our ROI?
From my experience, FortiGate products are affordable and worth the investment.
What other advice do I have?
I think for almost any small to mid-size business this is a great solution. Fortigate should definitely be considered before choosing a more expensive and complicated product.

Controlling and tracing with web console works nicely for windows systems, but for Linux, only IP can be obtained.
Valuable Features:
- Policy control
 - Web filtering
 - Application filter works smoothly.
 - Controlling and tracing with web console works nicely for windows systems.
 - Better QoS than Checkpoint, I believe.
 
Improvements to My Organization:
Previously, my organization had the Checkpoint firewall solution, which has been replaced by the Fortinet Fortigate solution, which is cost effective and more manageable from a beginner's perspective.
Fine QoS and Web based filtering solution is a plus.
Room for Improvement:
- Maybe Linux system monitoring can be improved by the developers of the product.
 - Although it has policy control and web filtering, these could be better.
 - Application filter needs more control options.
 - IP tracing works only so-so.
 - Controlling and tracing with web console for Linux only obtains IP addresses.

For price criteria, Fortinet wins over competitors. That being said, certain areas of the product need improvement
What is most valuable?
- Performances
 - VDOM
 - UTM
 - Consolidated Management
 - FortiGuard
 
How has it helped my organization?
- Endpoint control of mobile devices with Security Profiles compliancy checking, captive portal redirection, Antivirus, IPS and Web Filtering enabled on outgoing traffic (coupled to FortiClient solution)
 - Identity-based policies used to authenticated and profile users and guests whatever the media used to access the network (ie. Wired and WiFi)
 - Dynamic BGP routes injections to divert traffic requiring UTM inspection or DDOS mitigation
 - Two-Factor Authentication VPN SSL for itinerant users (coupled to FortiToken solution)
 - Active/Active cluster load-balancing http/https traffic
 - GTP tunnels inspections over GPRS backbones for pure-player telco operators
 - Distributed WiFi infrastructure with UTM enabled and managed from the central console like signatures and firmware updates
 - Classical IP/IPv6 Firewall with consolidated-management
 
What needs improvement?
- Fix all pending bugs present in 5.0.x branch
 - Improve the testing process of newly published firmware like using real and representative configurations submitted to consequent traffic load during a while
 - Support SNMPv3 INFORM requests
 - Uniform the scheduled backup between FortiGate, FortiManager and FortiAnalyzer
 - Integrate graphical troubleshoot tools for policies based on devices or user identities
 
For how long have I used the solution?
4.5 years
What was my experience with deployment of the solution?
Some few non-blocking bugs present in the latest release and which are now solved. In the past I encountered serious bug regarding SCTP and GTP supports. Fortinet helped me to qualify the bug, implement a temporary workaround and then published appropriate patches rapidly.
What do I think about the stability of the solution?
No. I always used the latest qualified-stable firmware recommended by Fortinet and check by own testing methods the stability of HW and SW before deploying anything into customer premises.
What do I think about the scalability of the solution?
With design and dimensioning parts well achieved I never encountered scalability issue. However it happened I had to troubleshoot some slowness and latency issues on existing projects already running live. Most of the time they were due to some design issues and non-optimized configurations like for instance “in” and “out” ports not handled by the same NP, policy rules non-optimized and non-used features enabled.
How are customer service and technical support?
Customer Service: 
Very good.
Technical Support:Very good.
Which solution did I use previously and why did I switch?
- CISCO ASA: Too expensive, performances issues, non-consolidated management between traditional ASA and inspection ASA CX, not the best security engines
 - Checkpoint: Very expensive but good solutions, not the leader in UTM segment
 - Juniper: Expensive but good solutions, not the leader in UTM segment
 - Cyrberoam: Attractive prices but not yet tested, looks like promising
 - Arkoon/Netasq: Obsoletes (Stormshield not yet tested)
 
How was the initial setup?
It was quite simple if you have at least a minimum of experiment with Firewalls integration. It is now even simpler thanks to the FortiExplorer application.
What about the implementation team?
In-house.
Which other solutions did I evaluate?
Taking into account the price criteria, nowadays Fortinet always wins offers in front of competitors like CISCO and Checkpoint. Mixing this key-point with other success keys like UTM features and performances.
What other advice do I have?
Contact Fortinet or Fortinet’s partner and ask for a POC.

I don't need to have a cluster because it's stable, but rules are not intuitive and the admin UI needs improvement.
What is most valuable?
It offers a proxy and a firewall.
How has it helped my organization?
It has a better processor than CheckPoint.
What needs improvement?
It's not intuitive, as the rules will be in the last place you look. You can look for a report for an hour, eventually getting a blank page. User experience for the administrator is basically not good as it needs to be more proficient.
For how long have I used the solution?
I've used it for two years.
What was my experience with deployment of the solution?
I have five ISPs, and it was hard to connect the LAN to the WAN. It did not go well and I had do to a roll-back.
What do I think about the stability of the solution?
The product is so stable I don't need to have a cluster.
How are customer service and technical support?
Customer Service: 
I use a service given by the integrator and it's better than Fortigate’s. The integrator gives me a guarantee that they will immediately replace my machine if a problem occurs.
Technical Support:I use a service given by the integrator and it's better than Fortigate’s. The integrator gives me a guarantee that they will immediately replace my machine if a problem occurs.
Which solution did I use previously and why did I switch?
I used an open-source product name Squid.
How was the initial setup?
It's straightforward, and was transparent for the users.
What about the implementation team?
We did it in-house.
What was our ROI?
It costs $200,000 and is only a bit better than the open source solution, which was free.
What's my experience with pricing, setup cost, and licensing?
You don’t have to buy the Fortigate analyzer, as you can also get the reports using Fortinet.
What other advice do I have?
It's fine as a firewall and as a proxy. You need to configure the rules right or else it will be hard to keep up with the logs.

Cisco ASA vs. Fortinet FortiGate vs. Palo Alto vs. Juniper SSG
Since IPv6 gets more and more important, I am using it by default on all my test firewalls, which of course support IPv6. However, when comparing the different functions and administration capabilities, they vary significantly.
Here comes my short evaluation of the IPv6 functions on the following four firewalls: Cisco ASA, Fortinet FortiGate, Juniper SSG, and Palo Alto.
Criteria
I was merely interested in the basic IPv6 usage and not in the typical firewall categories:
- Interface: IPv6 address and link-local address configurable?
 - Router Advertisement and DHCPv6: Whether the firewalls support nothing (–), only RA (-), DHCPv6 relay (ο), stateless DHCPv6 (+), or stateful DHCPv6 (++). The existence of stateless DHCPv6 is vital for delivering the DNS server IPv6 addresses to the clients. (The “IPv6 Router Advertisement Options for DNS Configuration”, RFC 6106, is not supported by any of these devices.)
 - Security Policy: Whether IPv4 and IPv6 addresses can be used in the same policy and whether address groups can have objects from both protocols.
 - Administration: How easy are the IPv6 functions to manage? Only via the CLI (–), fifty-fifty (ο), GUI but complicated (+) , or fully via the GUI (++).
 
Results
These are the results. They range from — via ο to ++.

Details
Cisco ASA
The Cisco ASA has no DHCPv6 instance running. That is: there is no way to run an IPv6-only network because clients won’t get the DNS server. The security policy is capable of both protocols. Everything is configurable via the GUI, which is not the best at all.
Fortinet FortiGate
The FortiGate is the only firewall with a stateful DHCPv6 server. Great. However, two distinct security policies must be used and nothing of the IPv6 settings are configurable via the GUI. WHAT???
Juniper SSG (ScreenOS)
ScreenOS is dead. However, most of the IPv6 functions are working quite good, except the protocol dependent security policies. Everything is accessible via the GUI, but sometimes on confusing positions.
Palo Alto
Palo Alto did a good job on the IPv6 interfaces and security policies. The GUI is quite intuitive and the policy accepts both protocols at the same time. Unluckily, there is no DHCPv6 server which makes it impossible to operate an IPv6-only client network behind a Palo Alto (without further servers).
Conclusion
It’s interesting to see the differences between those firewalls. While the Fortinet und Juniper firewalls support the whole SLAAC process incl. DNS servers, they have no single security policy for both protocols and are horrable to configure.
The Palo Alto is quite good to configure but lacks the DHCPv6 server. Same for the Cisco.
In summary, all firewalls position in the middle of my scale. From an IPv6-only view, I cannot say which one is the best. It depends….

It helps to come up with the requirements of proxy servers, but it does not have that much troubleshooting & network testing features.
What is most valuable?
The key features of this product are:
- Network security
 - UTM Features
 - Configuration and ease of deployment.
 - IP/User/Device Mac ID/Device Type based policy configuration
 - Traffic shaping
 - Load balancing
 - Ease of VPN configurations
 - Explicit proxy
 - Link segregation
 - Application signatures
 - Network object based HTTPS/SSL inspection etc.
 
How has it helped my organization?
In many organizations it helps to come up with the requirements of proxy servers, defining network traffic and the amount of bandwidth for any network object or specified user(s). It has also provided us with security compatibility with other network devices such as IP cameras, the video conferencing system, VOIP phones. It also logs & reports on individual users network activities.
What needs improvement?
The FortiGate series does not have that much troubleshooting & network testing features in its GUI, hence we’ll definitely be looking for some add-on features in near future.
For how long have I used the solution?
I have been using this solution for the past year.
What was my experience with deployment of the solution?
No issues yet.
What do I think about the stability of the solution?
No issues yet.
What do I think about the scalability of the solution?
For massive logs & reports (over a month) we have to go for a separate logging & reporting device i.e. FortiAnalyzer/FortiCloud, as this is not available in Fortigate itself.
How are customer service and technical support?
Customer Service: 
7/10.
Technical Support:8/10.
Which solution did I use previously and why did I switch?
We started with FortiGate itself.

The v5.6 GUI is much improved, IMO. Very happy to see the changes there. Some things are still a little hard to find, but not as many.
