Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product helps our organization to access sites located in different regions quickly."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The fact that I can log into the platform and see everybody, see logs, authentication failure, and see everything on one platform, is the most valuable feature."
"Built-in security templates, AV integrated, strong threat intelligence."
"The product's initial setup phase was straightforward, and since our company didn't have any problems with it, we didn't encounter many problems with the tool."
"Other than the additional security with exploit protection, we have simpler certificate handling, as we can keep internal servers using internal certificates continuously distributed and updated by Active Directory Group Policy, while the public certificates become updated only in a single place, FortiWeb itself."
"The ease of configuration is valuable. We have Azure WAF, we have OCI WAF, and we also have Cloud Armor for GCP, but their configuration isn't very easy. It's pretty simple in FortiWeb, and we can enable or configure whatever we want."
"If I need something from tech support, I can get it answered within the hour."
"The valuable feature of Fortinet FortiWeb vulnerability scanner"
"Fortinet FortiWeb enhances web security with its effective features that handle inbound and outbound traffic."
 

Cons

"Support is not that great."
"What I don't like about Fastly is that they charge a heavy price."
"Fastly's customer service area needs improvement."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"The solution's pricing could be better."
"The product should provide improved bot detection and management."
"There is room for improvement in the support. The response time could be faster. Plus, they ask for a lot of information. It is not easy to get support."
"Regarding areas for improvement, the documentation needs work. We had issues with a customer because the documentation didn't clearly show which devices can connect with FortiWeb WAF, leading to misconfiguration and difficult meetings. We also need deeper technical support - finding who's responsible for technical aspects is challenging. Hungary has a good Fortinet office with strong sales and pre-sales employees."
"Fine-tuning is a room for improvement in Fortinet FortiWeb."
"For users not familiar with Fortinet, it could be beneficial to provide more user-friendly analytics and reporting."
"No solution is 100% secure and the security could always be worked on."
"I would like to have an antivirus option."
"The false positives are annoying.​"
"Fortinet FortiWeb could improve in reference architecture for different deployment scenarios."
 

Pricing and Cost Advice

"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"Fastly is less expensive than one of its competitors."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"Fortinet FortiWeb's pricing is reasonable. Its licensing costs are yearly."
"FortiWeb Web Application Firewall's pricing is suited for small or medium organizations."
"The solution is cheaper compared with other solutions. It has a yearly license."
"FortiWeb can be purchased in VM mode for a lower price and the same features."
"It is a cheap solution."
"There's only one payment for the duration of the license. On a scale from one to five, I would rate pricing at four. I have not encountered any additional costs on my projects involving Fortinet FortiWeb."
"The tool is really expensive."
"The price of Fortinet FortiWeb is reasonable. This is one of the key factors of why we use this solution."
