It's easy to set up and configure and it provides excellent protection against threats such as Ransomware and Malware. The support team is also very helpful when you need assistance with issues that arise. You can use this product along side other products like McAfee or Symantec without any problems. We do not have any complaints about this software. I highly recommend using Securd DNS Firewall if you are looking for an effective solution to protect your computer network from malicious activity. Protecting our clients' computers from viruses and malwares has been a huge benefit to us. I like how easy it is to set up rules using the GUI or command line interface (CLI). It's very intuitive when you get used to it. The CLI can be confusing at times but once you figure out what each command does it works great! We use this product primarily as an antivirus software replacement. We are able to block more traffic than we would with traditional AV solutions.
