    DDoS protection providers vs DDoS protection scripts

    I am looking for some good ddos protection providers, via protected dns. I've searched on internet, but most of them are really expensive.

    Please tell me some ddos protection providers what could help me.(gige is too expensive btw).

    And I found some ddos protection scripts. How can a script protected a server from ddos? A sript like CSF or DDoS deflate?

    First of all, the protected dns will only mean that your nameservers are protected from a Denial of Service attack, in most cases.

    Firewalls like CSF and a script like DDoS deflate might help here and there against a DDoS, but it will eat up resources, as opposed to having your provider filter traffic, which will stop bad traffic before it reaches your server.

    What sort of attacks are you receiving? How many packets per second, how many mbps is the size of the attack?

    Implementing a system means you won't have instant DoS protection, as a filtering appliance needs time to analyse your traffic in order to precisely decide which packets are 'bad'.

    most of attacks are between 100Mbps and 700Mbps. A good solution for 500Mbps is SecurePort from staminus, but I need something for 100Mbps and 300Mbps. I found that DDoS deflate would have to run in a cron every 1 minute, and this is resource eater, like you said.

    Mod_deflate will actually not help you must against a real DDOS aimed to either saturate your uplink or max out the server or operating systems capacity to handle Packets per Seconds.

    What Mod_deflate does, is not much then use IPtables to stop certain attacks on httpd based on httpd requests. It is a tool to stop certain Denial of Services attacks, but it is not a DDOS filtering or mitigation method.

    EDIT: seems DDOS deflate is actually another script. Even so, PPS and link saturation limits do apply. There is not a script that can actually deflate that.

    In this case, CSF makes the same thing, KISS the same, APF too. all of them are using iptables. but do you know any ddos hosting providers, or ddos protection providers?

    And how much Packets per Second? bandwidth figures does not say much as all if you like to fight/stop/mitigate a DDOS attack.

    Blacklotus comes to mind. I suggest you talk to them.
    Gigenet seem to be reputable as well. But you labeled them as too expensive. Fighting DDOS attacks is not cheap altough.

    50-200k packets per second

    Mareshal, you need to be either on a DDoS protection provider or own the uplink and equipment to do the heavy lifting for you.

    Agreed. Either way when you start talking upwards of 700Mbps / 200k PPS then it is going to be costly.

    Although, the investment to hire a DDoS protection company will be quite a bit lower than the cost of equipment required to "attempt" to mitigate an attack of that size.

    Best of luck!

    Fighting DDoS you are looking at over $100 a month my friend! It is not cheap at all and an overpriced market. Good luck!

    We use a combination of hardware and a customized script we wrote in house. Over $50k for the hardware portion though, so probably out of your range.

    Like any market, there are suppliers who are overpriced. However, keep in mind that DDoS mitigation services are expensive because true DDoS mitigation itself is very expensive.

    Not only does the provider have to spend a lot of capital on purchasing specialized DDoS mitigation equipment, but they also have to maintain high capacity links with enough excess capacity to handle the largest attacks. Not only that, but they have to eat the bandwidth costs of the attack as well. Many attacks also require the attention of highly qualified staff to manually make adjustments to mitigate the attacks.

    If anything, I think DDoS mitigation may be undervalued, as the true providers are having to compete with the pricing of pretenders who do nothing except install scripts and mod_security.
