Executive SummaryUpdated on Dec 5, 2024

Fastly and AWS Shield compete in the web security market, with Fastly having an advantage in CDN capabilities and AWS Shield excelling in DDoS protection, making the choice dependent on security needs versus content delivery efficiency.

Features: Fastly offers real-time logging, customizable edge computing, and a robust network with numerous Points of Presence. AWS Shield provides integrated DDoS protection, seamless integration with other AWS services, and high availability.

Room for Improvement: Fastly could enhance its zero-trust security features, improve tools for hybrid reseller environments, and explore additional integrations beyond its current offerings. AWS Shield might lower the technical knowledge required for full utilization, expand beyond AWS ecosystem restrictions, and offer better cost transparency for advanced features.

Ease of Deployment and Customer Service: Fastly ensures straightforward deployment with a well-documented setup process and responsive customer support, making it ideal for quick implementation. AWS Shield's integration within the AWS ecosystem makes it convenient for existing AWS users but may require advanced technical knowledge.

Pricing and ROI: Fastly's pay-as-you-go pricing model offers flexibility and potentially lower upfront costs, with users noting efficient content delivery. AWS Shield, while potentially incurring higher initial costs due to comprehensive security offerings, offers significant ROI for security-focused businesses.

PranavTelang

Lead Architect at a comms service provider with 1,001-5,000 employees

Has enabled multi-layered threat mitigation but still lacks deeper visibility for advanced application attacks

AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods. It does not provide inherent protection against more sophisticated layer 7 attacks such as HTTP floods. In such cases, integration with WAF is necessary, which results in additional costs for customers. To protect layer 7, layer 4, and layer 3, customers must implement both solutions. The service also has difficulties with static detection thresholds, which may not be sensitive enough to detect smaller application-specific attacks. While AWS Shield is a key security service, AWS should enhance their expert support with 24/7 response for complex attacks, which is currently limited.

Patel Parth

Technical support engineer at Adobe

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.

Quotes from Members

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

Pros

"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."

"I recommend AWS Shield because it has proven helpful in tracking DDoS attacks within both my past and present environments, and without AWS Shield, a business could face potential losses, as this tool helps in identifying and mitigating fake traffic that disrupts applications, ultimately supporting business continuity."

"I am impressed with the product's multiple features like security."

"The solution's ease of use is the most valuable feature."

"It is quite scalable, and we have not faced any issues with its scalability."

"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."

"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."

"The product has a good mechanism to analyze trends and trigger events."

More AWS Shield pros

"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."

"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."

"Rate limiting is a good feature that protects from volumetric attacks."

"Compute@Edge features are valuable to me."

"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."

More Fastly pros

Cons

"The product needs to improve its logs and reports to make it read better."

"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."

"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."

"The product is expensive."

"We end up having to pay extra for features that AWS adds that we don't need."

"The product should give users more flexibility to customize their security policies according to their requirements."

"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."

"The time taken to detect anomalies must be reduced."

More AWS Shield cons

"What I don't like about Fastly is that they charge a heavy price."

"Support is not that great."

"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 product should provide improved bot detection and management."

"The solution's pricing could be better."

"Fastly's customer service area needs improvement."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"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."

Pricing and Cost Advice

"The tool's pricing is good."

"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."

"The tool is cheap."

"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."

"We pay $3000 per month for the solution."

"It is an expensive solution."

"Fastly is less expensive than one of its competitors."

"The solution is cheaper than other products in the market."

"You need to pay a premium price for the tool."

"The pricing has been very competitive."

"In my opinion, Fastly is priced competitively."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
