Threat intelligence has consistently minimized downtime and safeguarded revenue
Fortinet FortiGuard's machine learning capabilities contribute to our cybersecurity by performing numerous predictions and assessing possibilities, enabling us to prepare ahead for potential incidents. I have benefited from automated threat response, which is absolutely brilliant because if we have to go through logs to see what is going on, we would never finish. Automating these things allows alerts to be given so we can concentrate effort on critical areas, helping us to optimize our resources effectively. We are also looking at automating the response, where response can be automated, and then we can focus on forensic investigations to understand what happened and see whether we need to tweak the automation to make it work better. The benefits I gain from using Fortinet FortiGuard include peace of mind. It has contributed to ensuring that we are always available and can meet our availability targets. This means that productivity is maintained, and revenues will rake in as planned. The moment something gets through and causes a breach, likely causing downtime, it means you're losing money.

File protection has improved and now keeps millions of daily transfers secure and compliant
In my organization, while using this tool, we found that there were a few files flagged as suspicious; however, those were not suspicious and it was a false positive, so that can be improved. False positive results were an issue, and it took time to scan files if the file size was greater than 1 GB. For larger files greater than 1 GB, it needs to be improved. In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly. We have already covered all the main suggestions; however, it can be improved to reduce false positive results, and scanning could be faster to process more files in a day.

"The benefits I gain from using Fortinet FortiGuard include peace of mind; it has contributed to ensuring that we are always available and can meet our availability targets, which means that productivity is maintained and revenues will rake in as planned."
"The best feature of MetaDefender is that it can isolate USB devices from the connected network, blocks malware and unsafe files, and ensures all endpoints follow security policy, so that my organization remains safe and reduces the risk of these threats."
"I assess the effectiveness of MetaDefender in blocking or sanitizing content based on policy as very good."
"The percentage of accuracy is great and the integration of multi-scanning and Content Disarm and Reconstruction affects my data security operations effectively because OPSWAT blocks the file types that we are not willing to have inside the company or are not approved."
"For one of my clients, a major bank in Turkey, they reported saving approximately 30 percent of their SOC time on analyzing emails since implementing MetaDefender."
"MetaDefender has positively impacted my organization by reducing the risk of file-based attacks, which has significantly improved our overall defense against phishing and malware delivery techniques."
"MetaDefender is 100% stable, making it one of the best cybersecurity solutions we offer, which provides confidence in promoting and recommending it to others."
"I like the simplicity, the way it works out of the box. It's pretty easy to run and configure. The integration of the network devices with the ICAP server was easily done."
"The best features of MetaDefender include its ability to detect malware and vulnerabilities, which I also use at server levels, including production and testing servers, helping me identify and address vulnerabilities by applying patch updates."
 

Cons

"If the tool can be cheaper or less expensive, it can be good for users."
"The dashboard is an important and integral part of the product that could be improved."
"When creating a ticket for support with configuration features, the support is reluctant to provide that support."
"I think that automated response could be improved if they can add automated response features into Fortinet FortiGuard."
"Currently, for our usage, the areas that have room for improvement are pricing and customization."
"In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective."
"I would rate it an eight because its interface can be improved and it can improve their integrations as well, so there is room for improvement."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
"While MetaDefender's mail gateway already gives fewer false positives, there is still room for improvement in reducing those even further."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"I did not manage to enroll my IoT devices, including my child's device running on iOS and some Amazon products."
"The documentation is not well written, and I often need to talk with support."
"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
 

Pricing and Cost Advice

"If one is very cheap and ten is very expensive, I rate the tool's price as a six to seven."
"We bought a three-year license, and that was pretty expensive. We agreed that it was really worth buying. It could be cheaper, but we understand that quality comes at a price."
