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

"Compute@Edge features are valuable to me."
"The product helps our organization to access sites located in different regions quickly."
"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."
"Its initial setup process is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product's initial setup phase is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"The GUI makes it easy to scale in terms of learning and utilization."
"The solution has a very simple deployment."
"It is a good product. We have just blocked everything coming from some geographical locations or certain countries, and it has been working very efficiently when I look at logs, events, and incidents generated from the system. It is generating very good analytic reports about it. This is the most valuable thing about this solution. It has load balancing and almost everything that a web application firewall needs. It is very flexible and easy to learn and configure. It can be easily learned and configured by using the information available on different channels such as YouTube."
"The product's initial setup phase was easy."
"The reason I recommend this product is because it guarantees that your network will be safe if it is set up properly and you fully utilize most of the functions."
"High-performance and detection engines, provide a high rate of exposure of web attacks."
"Fortinet FortiWeb has positively impacted my organization because most of our servers and applications are secure from hackers and other security threats."
"The machine learning on FortiWeb WAF is valuable."
 

Cons

"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."
"Fastly's customer service area needs improvement."
"The product should provide improved bot detection and management."
"Support is not that great."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"What I don't like about Fastly is that they charge a heavy price."
"The solution's pricing could be better."
"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."
"The F5 solution has more features than Fortinet FortiWeb, such as multiple load balancing."
"The solution could improve by providing more integration with solutions other than the Fortinet family."
"They could improve their support a little bit for faster response time."
"It may be better if it were easier to create roles."
"The documentation for the machine learning could be better."
"The solution could have more customization."
"It would be good if the solution integrated with other solutions, like SAP."
"The automation piece can be improved. Although they say it can be automated very well, there is still manual work. Its usability should be improved in terms of automation because we want to build an infrastructure with code, but you can't do that easily with this solution. If they can give us APIs in the firewalls that we can tap into, it would be perfect."
 

Pricing and Cost Advice

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
"The solution is cheaper than other products in the market."
"It is an expensive solution."
"The pricing has been very competitive."
"You need to pay a premium price for the tool."
"In my opinion, Fastly is priced competitively."
"Due to the situation in Iran with the sanctions, the price of this solution is very expensive."
"It is not a cheap product. It is not like a Linux or a Genex that you can deploy. It is a hardware appliance, and it is built for a specific reason and reliability. It is an enterprise-class solution. You wouldn't find an SMB investing in something like this."
"Previously, for each project, the cost was $800 to $1,000 per application. Now, it's $100 to $120. For some of the applications, there is a 90% reduction, and for some of the applications, there is a 50% reduction. We're paying only $500 to $600."
"I rate the tool's pricing an eight out of ten."
"The solution is a bit expensive when compared to other products."
"I would rate the pricing a four out of ten."
"The price of Fortinet FortiWeb is reasonable. This is one of the key factors of why we use this solution."
"So far, I have been pretty pleased with the way it's priced and licensed. The way it's done makes it easy, especially for an organization like us, so I've been pleased with the way it's priced and licensed right now."
