How to save resources and to attract more customers for hosting company.

Spam FireWall is an additional option in the anti-spam plugin CleanTalk. The principle of operation SFW differs significantly from the mechanism of anti-spam plugins.

CleanTalk anti-spam filters spam bots at the moment when they are trying to post a comment on the website, register, i.e. make a POST request. In some cases, the spam bots sends not only POST requests, but GET, that is downloads web pages and thereby overloads the site with requests. In small amounts it is imperceptible, but when the website receives 20 000 – 80 000 spam queries per day, it may affect the CPU usage.

CleanTalk SpamFireWall allows you to block POST and GET requests to the website and does not load a page.

The spam bot is given specially formed page.

SpamFireWall will block most (about 99%) of requests from spam bots, because the base is formed of the most active spam IP addresses. The rest of the spam bots will be blocked by anti-spam service in the POST request.

In addition to the spam bots will be blocked all HTTP/HTTPS requests from spam active IP addresses. It helps to block HTTP DDoS attacks, SQL attacks, scanning website, etc.

If the clients of a hosting provider use SFW on their websites, it can significantly reduce the load on the CPU servers. This allows you to place on one server more websites, to make the cost lower or to increase profits. To offer its current and new customers additional free services included in the rate, and thereby increasing the value of hosting services and customer loyalty. Customers do not have to spend time searching for a working anti-spam solution and test it, they will get a proven solution with the hosting.

The percentage of blocked requests usually from 7% to 30%, depending on the traffic of the website. The most appropriate use of the service on a shared hosting, as it gives greater efficiency due to a larger number of clients on the server.

Hosting providers use on their servers some software solutions to block malicious traffic, but as a rule, used a database of IP addresses is incomplete or they do not always intersect with the database of IP addresses CleanTalk. Therefore, web sites customers are exposed to tens, hundreds and even thousands of spam attacks per day. In addition to spam attacks from these IP addresses, there are other types of attacks on websites bruteforce, hacking, DDoS, SQL injection, etc. CleanTalk also get the most current information about IP addresses and their activity through cloud technologies.

As mentioned above, customers prefer to get all-in-one and not waste time looking for solutions. Offering customers hosting with anti-spam solution, you save them a lot of time to focus on the development of the project and business.

Often the hosting provider does not see any requests or needs of the customer, because such questions accepted to solve on their own, my site – my problems, and hosting is just a place where the site is. In addition to saving time and resources of the client, you give them a solution to the problem, which concerns every site.

Based on experience in the ISP, it is possible to compare the needs of customers. When using an ISP, we are often faced with the question, which turned out to be the cause of viruses on client computers, which have suffered due to both clients and network infrastructure. We chose an antivirus and started offering it to clients, we have included a free version in the price and have received tens of thousands of installations. Thus, we solved two problems: the problem of clients and problem with the load on the network. At the same time direct inquiries about an antivirus we have not received. It was an unconscious need that we have helped to satisfy. So it is with hosting customers, you can help them solve their problems and remove some of the load from the host.

CleanTalk provides its clients work logs of the service so clients can monitor the entire process of protecting a website from spam.

For each request there is a record containing all required parameters date/time, IP/email and text messages.

The client can check the correctness of filtration, because he can view the text or by checking IP/email, whether recorded other attacks with these IP/email to other websites. Efficiency of determination spam bots is 99.982%. Pay attention to the reviews in the catalogs, there is not a single negative comment about the quality of anti-spam service.

We do not offer to sell to hosting customers CleanTalk Anti-Spam, and include it as an additional free option in the tariff. Customers only have to install the plugin CleanTalk on the website and it will immediately work. CleanTalk provides tech support and customer service independently.
