Cloudflareの製品詳細

良いポイント:

The free plan is great for small to medium-sized websites. It has all you need at no cost.

Also every now and then my site looks odd. I clear the cache on site and browser and it still looks odd.

Cloudflare is Invaluable!!

5.0 7 か月前

製品を使ってみた感想: Cloudflare has been an invaluable tool to help reduce the attack profile of the websites I run.

良いポイント:

The fact that it hides the origin IP of websites, and allows page rules to direct traffic, even on the free plan.

改善してほしい点:

No problems with Cloudflare at all, always use it for my and customer's domains.

While there are some challenges with configuration and caching, the user-friendly interface and robust support make it a strong choice for most users.

良いポイント:

Cloudflare offers robust security features, improves website performance with its global CDN, provides reliable DDoS protection, and offers easy-to-use management tools.

改善してほしい点:

Cons of Cloudflare include potential service disruptions during configuration, occasional issues with caching, limited customization for advanced users, and dependency on their infrastructure for security and performance.

製品を使ってみた感想: months ago i converted all pro subscriptions to free, this is also neatly indicated in the account that it will change to free on the 27th of the month.... but every month they simply collect and the downgrade is moved one month. And now that I no longer have 1 active domain, they are now charging a pro subscription for 24x dirty dirty..........

良いポイント:

Now nothing afterwards, they are scammers

All-in-One Solution for your websites

5.0 3 か月前

製品を使ってみた感想: I've had a really smooth experience with Cloudflare. In addition to domain registration, they offer many options to make your website safer, faster, and more efficient. It’s everything you could want in one platform.

良いポイント:

In my opinion, Cloudflare is the best domain registrar out there. You only pay the basic ICANN fee with no additional charges - at least that's what they claim. It's cheaper compared to competition either way.

改善してほしい点:

I wish they had a mobile app so I could monitor website stats and other details more easily. However, their website is well-designed, which helps make up for it. Another drawback is that you can't change a domain’s name servers without a paid plan.

Cloudflare is

4.0 昨年

製品を使ってみた感想: We have used Cloudflare for our company and personal websites for over four years without many issues. They have great features and if you are not tech savvy with the installation of SSL Certs or setting up rules this product can help you a lot. Their support can be a bit hit and miss but you usually get a response within 24 hours. We have seen some of the biggest and best brands in the world use Cloudflare and it’s really good how much you get for the price.

良いポイント:

Our company uses Cloudflare for all of our websites. Cloudflare acts as a CDN, a firewall and also a performance layer for websites as well as protecting our websites from attacks. They respond to our needs quickly and it's relatively insexpensive

改善してほしい点:

The customer support could be a bit better.

Cloudflare is a poor-mans' dream for Content Delivery Optimization

4.0 2 年前

製品を使ってみた感想: Very positive. If you're running a website or web services and you don't have the big bucks to scale with Azure/AWS, then consider these guys. They very seldom let you down.

良いポイント:

What's not to love about it? It has some of the cheapest and fastest content delivery tools on the planet. It has a free tier if you're just a cheapskate, but the paid tiers are pretty modestly priced among industry competitors. There are basic security filters in place and a few other optimizations for regional support (they have more data centers than most others with less latency). Their DNS/Name services resolve quickly and with fewer disconnects.

改善してほしい点:

Support is kind of a chore, just because they have so many customers. I think it's something they're getting better at though.

良いポイント:

1. Configuring and manging is effective in cloudflare. 2. Helps to secure and make our private environment with this. 3. It is pay as you go plan with centralized management.

改善してほしい点:

1. False alerts are one of the biggest issues that encounter almost every day. 2. Interface is little complex and clumsy. 3. Little latency in filtering the information and it usually block some useful scripts as well.

Cloudflare...has lost its luster

3.0 2 年前

製品を使ってみた感想: Cloudflare has evolved from a simple tool to guarantee 24/7 availability and quick response time. When I compared it to QUIC.cloud and LiteSpeed, I found it did not perform as well.

良いポイント:

Cloudflare provides a number of features that are important/essential for small business websites (DNS management, caching, SSL, etc.)

改善してほしい点:

Overly complex and increasingly expensive without achieving optimal performance and 24/7 guarantees.

Slick and Reliable

5.0 7 か月前

良いポイント:

What I liked most about Cloudflare is its robust security features, especially the DDoS protection and SSL/TLS encryption, which significantly enhanced my website's security. The global CDN improved load times, and the intuitive dashboard with detailed analytics made management straightforward.

改善してほしい点:

What I liked least about Cloudflare is the occasional complexity in configuring advanced features. While the basic setup is straightforward, some advanced settings can be confusing and require a steep learning curve. Additionally, customer support response times can sometimes be slow, which can be frustrating when dealing with urgent issues.

Peace of mind

5.0 8 か月前

製品を使ってみた感想: Hugely positive and I've never used it to it's full potential.

良いポイント:

I came across cloudflare around 10 years ago following a significant DDOS attack against our business website. Following the attack out hosting company refused to continue hosting our website and we were forced to move. Our new host was happy to have us and recommended cloudflare as an additional layer of protection and I've been using it every since.

改善してほしい点:

When using their wordpress optimisation features, you never know whether they're conflict with another optimisation plugin.

Security will always be your aim here

5.0 昨年

製品を使ってみた感想: My overall experience was really satisfying

良いポイント:

I’m using cloudflare for 2 years now in using the DNS services to secure my computer and my network in general it’s like using a VPN without using a VPN which helped me to access lots of stuff that wasn’t available in my country of residence. The app has lots of uses for cybersecurity, computer security, network security etc and it’s really good and reliable

改善してほしい点:

It sometimes bugs or freezes but it’s hard to find an app with all these combined features in one place

Cloudflare - Online Security 24/7

4.0 2 年前

製品を使ってみた感想: The overall experience has been very positive. Protected, supported by a great service, with the options to alter and pivot in real time saves time and money. Cloudflare is a clear first choice.

良いポイント:

From the protection of domains, customizable firewall and caching rules, DDoS protection, and the ability of their support teams to implement better and faster solutions, Cloudflare is in my opinion a top tier choice for any company wanting to better protect their online presence.

改善してほしい点:

Some options in Cloudflare are defaulted to a lower standard then what is most secure currently.

Above and Beyond Cloud Security

5.0 昨年

製品を使ってみた感想: I use this for my own businesses, as well as employer organization, and would recommend it to my IT friends and colleagues if they also didn't already use it.

良いポイント:

I was blown away on initial use of Cloudflare and their free tier offerings, and has led me to consider further purchases of their services. Their DNS proxy service alone is invaluable, and I would be remiss to not use it.

改善してほしい点:

I do wish pricing offered more granularity for smaller organizations, as it can be confusing which products are free until you attempt to set up a service offered.

Enhancing Website Security, Performance, and Reliability: A Positive Experience with Cloudflare

5.0 2 年前

製品を使ってみた感想: Cloudflare is well-regarded as a comprehensive solution for enhancing website security, performance, and reliability. Also, it's free SSL for beginner's websites.

良いポイント:

Cloudflare offers a comprehensive suite of security services, including DDoS protection, web application firewall, bot management, SSL/TLS encryption, etc. These features help to protect websites and applications from a range of threats, including hacking attempts, malware, and phishing scams.Cloudflare's global network of data centres and content delivery network (CDN) can improve website and application performance by reducing latency and delivering content faster. Cloudflare's load balancing and caching features can also help to distribute traffic across multiple servers, improving overall performance and availability.Cloudflare's user interface is intuitive and user-friendly, making it easy for businesses to set up and manage their security, performance, and reliability services.

改善してほしい点:

While Cloudflare offers a free tier with basic features, more advanced features and services are expensive. I am concerned about the amount of data Cloudflare collects about my websites, particularly if they handle sensitive or confidential information.
