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."
"Rate limiting is a good feature that protects from volumetric attacks."
"Compute@Edge features are valuable to me."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Its initial setup process is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The reporting and token system is good."
"The features of FortiWeb Web Application Firewall (WAF) that have proven most effective in protecting web applications include web filtering, DDoS protection, geo-location blocking, and blocking SQL injection attacks."
"Some of the threat detection analytics and the filtering capabilities they give us for filtering a certain type of information that we don't want coming into the site are its valuable features. The analytics are pretty good in terms of being able to see what threats have been detected and mitigated, where they're coming from, and things like that."
"The most valuable feature is the web application firewall (WAF)."
"It helps us prevent attacks on servers."
"The product has a very user-friendly dashboard."
"FortiWeb has a very extensive library of known attack signatures, which makes the product fit for any environment, regardless if the customer uses Windows-specific or non-Windows-specific applications."
"It is a stable product."
 

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."
"The solution's pricing could be better."
"What I don't like about Fastly is that they charge a heavy price."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"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."
"The product should provide improved bot detection and management."
"Support is not that great."
"Fine-tuning is a room for improvement in Fortinet FortiWeb."
"Describing security rules should be improved. It's tricky to define new feature tools when you want to describe an attack pattern and want to block it."
"I know that we have run into some issues with an SSL certificate and how it functions. Sometimes this breaks connectivity or just limits certain websites that are whitelisted."
"The dashboard evaluating the performance of each application connected to the web app's firewall is quite helpful, but the tool is only available in application performance management. So I think if Fortinet could better integrate that particular feature, it would add a lot of value to the product."
"The product's scalability could be better."
"The solution could improve by being able to handle different use cases."
"Fine-tuning is a room for improvement in Fortinet FortiWeb."
"They can introduce a scaled-down version for the SMB market. It would be very competitive in the environment."
 

Pricing and Cost Advice

"It is an expensive solution."
"The pricing has been very competitive."
"Fastly is less expensive than one of its competitors."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"FortiWeb has a good presence because of its price."
"​It really pays off to buy licences for multiple years​."
"​The pricing is reasonable."
"It should be somewhere about 36,000 Euros. That's the cost for three years. It's moderately priced."
"The solution gives us the best price to performance ratio."
"It is an expensive suite and it is an expensive solution, but it is a manageable one for an enterprise."
"When I use any other firewall, I have to take a license. It could be a perpetual license or subscription-based. In both cases, we have to pay some amount in advance, whereas in the case of FortiWeb, when using it as a service, I am paying half a dollar only for the domain name, and then I am paying based on the traffic or the number of requests."
"Keep a loose margin between your actual bandwidth and the product sizing when using hardware appliances. Only virtual machines are upgradable to larger sizes."
