For almost a month For almost a month, I have unsuccessfuly tried to renew my certificate with this company. Beware, they also operate under the name Sectigo, and presumably they'll soon get a third name, as comodo and sectigo are already tarnished beyond repair. They don't communicate back, they don't tell you what problems or next steps are, so you have to keep calling their support for any hope on progress. For the money paid for a certificate, this is a horrible scam.

I'm afraid your worst fears are… I'm afraid your worst fears are confirmed. I'm here because the customer support is so rude and unprofessional, not answering my installation question properly that I began to suspect a scam. The certificate didn't work but the guy didn't seem to want to help. The technical support link meant you had to register first but a chat line came up first. Eventually I registered but had the foresight not to use my normal password. I wouldn't use their keychain link either but its up to you!

Absolutely Unacceptable. I installed Comodo’s free antivirus for Macintosh. When installed, it immediately reported an error with the scanner. Ran the diagnostics, and it found errors, but couldn’t fix them. I tried to uninstall, and it failed, I tried AppZapper. When I rebooted, the service STILL loaded! It had baked itself into OS X. I went the extreme route. Backed up my data, and wiped the disk. Damn unacceptable. I won’t be getting any antivirus products from them again, free or paid.

Comodo One is the way to go Comodo One is the way to go. Previously I had used a different vendor for security, patch management, MDM, remote takeover, and IT ticketing. Comodo does this all under one console. It’s made my network easier to manage and was able to consolidate all 5 of those costs into one. Who doesn’t like saving money?!?

Stay Away. Stay Away. Comodo - a sham company, creating insecure knockoff products. One of the most famous ones is Chromodo - insecure crapware, copy of Chrome.
