    Imperva Incapsula is the solution to have for DDoS at L7, L3 and L4. This effective solution also provides CDN, LB, ADR, DNS protection, SIEM integration and of course has an awesome WAF! Cloud based, OPEX only - no HW!! Easy to use - done and done!

    i think it's not just a DDoS on the DNS issue but the resiliency you need to provide for your Internet services. So, to better answer your questions, you have to provide some sizing of the traffic per site, the kind of internet services and number of concurrent users, the source where most traffic is coming from (West coast, East coast). It's always a balance of efficiency and practicality.

    Actually we (Radware) are one of the market leaders in both of the requested solutions.
    We offer ISP load balancing and Hybrid DDoS protection.

    Radware’s Linkproof (first in the industry) to ensures optimal application service level.

    We optimize in real time application performance in normal WAN state for both inbound and outbound traffic, when a service is disrupted we will divert traffic from highly-utilized links and ensure service-level for real time application or business related ones (for instance VoIP , voice or just cloud applications like office 365), In addition we maintain high WAN (ISP) availability at all times and steer the traffic to the operational links when failure occurs, compared to BGP protocol we will do it instantly with no impact on the applications.

    Unlike most of the competition Radware user total round trip time mechanism to ensure best user experience at all time, Radware owns a patent for this technology.
    LinkProof is application aware and will use smart prioritization mechanism to ensures bandwidth management and overall bandwidth for latency-sensitive apps.
    Our APM will monitors all transaction end-to-end as experienced by end user to show user friendly graphs statistics and dashboards.
    Load balancing different data centers can be easily achieved with our GSLB license, our Global server load balancing (GSLB) allows Web hosters, portals and enterprises to distribute content and services geographically.

    For the DDos part, we can offer protection up to L7 and SSL encrypted attacks both on prem and in the cloud, or a hybrid solution, Radware uses the same technology both on-prem and in the cloud which means when a signature was created it can apply instantly the signature in the cloud and save the le-learning process.

    In addition we use our patented "user behavior" mechanism and not only rate limiting.
    Reach out for more options and fine tuning the solution.

    How may I help? I mean do you need help in suggesting a working solution, design or some hands-on configuration of existing equipment to work around the threat.

    For your load balancing requirement,
    For your DNS requirements,

    Hope the information provided would be useful for your consideration.

    Already many good suggestions listed. I'll add another DNS provider to look into: NS1 ( They have options for private managed DNS, dedicated DNS, and a control layer for load balancing based on any number of policies you set.

    All of the DNS providers listed can provide a layer of defense against DDoS, with the CDNs (Cloudflare, Incapsula, Akamai) also offering WAF. Given the nature of infrastructure attacks, many enterprises are looking to have redundant providers at the DNS level in addition to your use of separate ISPs for internet traffic. That may be an additional factor to consider in your RFP process.

    it_user316782 - PeerSpot reviewerit_user316782 (‎IT Security Specialist )

    Take a look at DOSarrest. They offer a low cost quick and effective Proxy solution to mitigate DDoS attacks across their global POP's as well as a BGP/GRE option if preferred called Data Center Defender. They include Load balancing and a WAF as standard features.

    for DNS DDoS Protection you may use Incapsula DNS Protection OR move your DNS services to a big DNS player with DDoS protection OR have a combination of both.

    For your webservices you may use a Balancer to balance the load between your ISPs and provide High Availability also (one ISP goes down). For this you should also use your DNS to amend the dns entries.

    In case you are using Incapsula you can have both your websites active at the same time (load balance) and have a WAF,CDN and DDoS protection.

    Reviews from Real Users

    “Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. If you have a connection between your website and your host, the server, Cloudflare, and the host, you don't necessarily need a certificate.”  Spencer M., Owner at Tech Exchange

    “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.” Daniel P., Network engineer at Ufinet

    The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service.” A PeerSpot user who is a Competence Center Manager at a tech services company.
