Truly bad customer support. Ticket is unanswered fro over 1 month. Don't support TCP.
Response from Cosmic Guard, Inc.Jun 24, 2026
Hi! So sorry about the experience you had. There is a message displayed when creating a support ticket that tells you to instead use live chat as support tickets are not responded to currently, and live chat is open 24/7. Feel free to chat in at any time. Also, we do support both TCP and UDP.

Didn't even work! Tried everything, even reaching out to their ghost support. No reponse, no fix.

Hi there. Sorry to hear about your experience. We have 24/7 live support available at any time which is initiated from the main website. Support tickets are unfortunately replied to with a lower priority, and we will actually be removing them completely in favor of live chat permanently. Feel free to pop into live chat so we can give you a hand.

I opened a high priority ticket in regards to DDOS attacks happening at that current moment. This was at 9am, I still have yet to receive a reply and it is now 16:50. The attack is over, it was over at 11am, it was more cost-effective for me to just raw dog the attack than wait on their "high priority" response. Really makes you wonder what a "low priority" response time is like, I dread to know.

Our Guardian service was temporarily suspended 2 weeks ago, we are not offering instantaneous DDoS protection for non-Enterprise clients currently. Apologies for the late reply on your ticket, it's a weekend, and given what I mentioned we are prioritizing our other support avenues currently.

CosmicGuard has been a source of continuous problems for us. For the first several months, we experienced persistent BGP issues, which the team consistently dismissed as not being their fault. Only after persistent pressure did they acknowledge their mistake and resolved the issue, offering us compensation for just one month despite the ongoing issues we had been paying for. Afterward, during a migration of our equipment, the same issue resurfaced. Once again, they insisted it wasn't their fault and even ignored our support requests. The repeated problems and poor customer service have been extremely frustrating.

I have used this company in the past. Big trombone effect and it was really bad for the game servers I was hosting. It still has these issues to this day.

Hi there! I looked you up in our systems and unable to find anything. Could you please fill out the information request so we can discuss this?

CosmicGuard is simply a joke. I requested support during the trail period and the only response I received was that it was really my problem, and absolutely not theirs. After that, support was no longer responded to. Please find another provider for Anti-DDoS. Believe me, there are better options than one that charges €20/TB for bandwidth.

Purchase of Cosmic made on 09/29/2023. Once the service was delivered, a client received attacks with 10Gb/s incoming (With filter). Cosmic responded that the problem stemmed from a configuration issue on our end. After 3 checks, Cosmic continued to claim that the problem was on our side. After 3 more checks, Cosmic finally looked into it & admitted that the problem was on their end. After hours of waiting, and being honest, Cosmic finally resolved the issue. The panel to view the attacks does not work (Impossible to see correctly). There is no panel to add or modify rules; you have to manage on your own with their API. Regarding support, the support is absent, no response on live chat, on discord, or on slack. If you need help, you can wait. In the beginning, when everything was corrected, Cosmic worked very well, but when you receive specific attacks, Cosmic is no longer present. During an attack that causes problems with your service, Cosmic will ask you for a PCAP lol. A lot of problems, the lack of support is evident, they do not want to admit that the problem comes from their fault. It's a shame, and I am very disappointed.
