Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Ifeanyi Stanly Nwokoro - PeerSpot reviewer
Has ensured ongoing protection against cyber threats and provides timely automated response while requiring improvements in cost structure and performance transparency
Business inherently involves risk, and it's important that services continue to improve. AWS Shield is not an exception. Regarding advanced Shield protection pricing, there should be cost protection for most DDoS events. The pricing model should be based on service usage rather than a flat monthly rate. The advanced technique package, while premium and not available to every user due to cost implications of $3,000 per month, offers valuable features including real-time attack visibility and 24/7 access to the DDoS response team. Integration is paramount, particularly with the Web Application Firewall's rule-based blocking paradigm that helps in balancing routes, especially route 53 and the global accelerator. AWS Shield uses pattern recognition to analyze traffic, and certain attributes are immediately intercepted. The assessment process is profound, and the service maintains consistent availability. From a software perspective, there are improvements needed regarding antivirus and network security. Additional engineering improvement requirements would benefit AWS Shield.

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"The most valuable feature of Cloudflare DNS is security."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The solution provides good load balancing and protection against DDoS attacks."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The solution's ease of use is the most valuable feature."
"The product is easy to use."
"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."
"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."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"It is quite scalable, and we have not faced any issues with its scalability."
"The support team was helpful."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
 

Cons

"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"The solution could be more user-friendly."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"The solution could work at being less expensive. It costs a lot to use it."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"The product needs to improve its logs and reports to make it read better."
"Perhaps the time required to detect anomalies can be reduced."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"The product is expensive."
"The time taken to detect anomalies must be reduced."
"We end up having to pay extra for features that AWS adds that we don't need."
"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 product should give users more flexibility to customize their security policies according to their requirements."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"A free version of the solution is available."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The price is reasonable."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The tool's pricing is good."
"The tool is cheap."
"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."
"We pay $3000 per month for the solution."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
