Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
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.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.
Alark Singh - PeerSpot reviewer
Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.

Quotes from Members

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

Pros

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Cloudflare has many features."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The DDoS protection is the most valuable aspect of the solution."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
"The equipment works very well, and I have not encountered any issues with it."
"The product's initial setup phase was really easy."
"The protection resources and the support are valuable features of the solution."
"It is a user-friendly product in terms of monitoring and updating policies."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The Explorer allows you to know the traffic between source and destination."
"I would recommend Illumio to all sizes of companies."
"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
"The most valuable feature of Illumio Adaptive Security Platform is monitoring. When I have no requirement from the other application, I can use the web block traffic to build."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"The solution is easy to use."
"Customer support is excellent."
 

Cons

"An integrated SSO feature would be useful for Cloudflare DNS."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"Support response time could be improved."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"I would like to see analytics, big data."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The product’s pricing needs improvement."
"The web interface could be much better."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"Some of the features that can be improved is offer additional guidance on creating an effective and risk-free tagging policy would be highly beneficial."
"I would like to see better data security in the product."
"We need more details on areas where there is an error or a traffic blockage. I would like the tool to offer a more detailed view."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"The customer service is lagging a bit. It could be better."
"I have not had the chance to experiment deeply with it."
 

Pricing and Cost Advice

"A free version of the solution is available."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The tool is a premium product, so it is very expensive."
"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."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is minimal compared to other products."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
"It's quite pricey."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
