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.

Handles high traffic efficiently and simplifies complex routing with rule-based logic

I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

Quotes from Members

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

Pros

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

"The product is easy to use."

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

"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."

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

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

"If most of your internet presence from your application side is in AWS, AWS Shield is a great option."

"It is integrated with AWS. So, it gives you a good first step."

More AWS Shield pros

"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."

"HAProxy enabled better performance at lower costs, which allowed us to provide more stability to our clients."

"I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."

"HAProxy's TCP load balancer is excellent and super stable."

"With centralized SSL termination and automated renewals now in place, that time requirement has dropped to nearly zero hours, translating to dozens of hours saved per year."

"The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."

"It is stable. Period. Will not fail unless you do something wrong."

"The ease of use of the configuration, and great documentation, are the most valuable features for us."

More HAProxy pros

Cons

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

"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."

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

"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."

"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."

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

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

More AWS Shield cons

"The logging functionality could use improvement, as it is a little cryptic."

"HAProxy could do with some good combination integrations."

"The solution's dashboards and reports could be improved."

"I would like to see better search handling, and a user interface, with a complete functional graphical unit."

"The basic clustering is not usable in our very specific setup."

"I would like to see a two (or more) native cluster support without third parties or DNS manipulations."

"There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable."

"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."

Pricing and Cost Advice

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

"The tool is cheap."

"The tool's pricing is good."

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

"It is free of cost."

"HAProxy is free in the initial offer. However, pricing can be improved."

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

"The licensing fee for the solution is $690 per unit annually."

"The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."

"Very good value for the money. One of the simplest licensing schemes in this category of products."

"HAProxy is a free open-source solution."
