Is Comodo Safe? Yes!: How Comodo Client Security Works

How Comodo Client Security Works

Cybersecurity is one of the biggest challenges in today’s world. It’s nearly impossible to do business without being connected to the internet so it’s a problem for almost everyone.

Keeping your computers and data safe on the internet takes some work but applications like Comodo Client Security make it a lot easier. You might be wondering “Is Comodo safe?” Let’s find out.

What Is Comodo Client Security?

Connecting a PC to the internet in today’s world is like walking into a flu clinic. If you haven’t been vaccinated, you’ve got a much higher chance of getting the flu yourself. Connecting your PC to the internet without good security and malware protection means there’s a good chance of it being “infected”.

Comodo Client Security (CCS) is an enterprise-class security package that monitors your PC 24/7 for security threats, malware, and other threats. CCS includes several modules that all work together to keep you safe, including:

  • Antivirus
  • Firewall
  • Containment
  • Host Intrusion Protection (HIPS)
  • Rescue Disk
  • Website Filtering
  • Other advanced protection features

It’s unfortunate that there are so many potential threats coming at you but Comodo will help keep you safe.


The CCS antivirus module protects your PC from viruses, worms, and other types of malware. These can spread through email, downloads from the internet and attachments on USB sticks or other storage and Comodo protects against them all.

You can schedule regular virus scans so they run automatically at a time that you’re not using the PC or you can run the scan on-demand. You can also use the drag-and-drop interface to scan individual files for threats which makes it easy to check attachments and other files you receive.


Comodo Client Security includes a packet filtering firewall module that filters all inbound and outbound network traffic. The firewall monitors all traffic to and from your computer so it can identify any unusual or threatening activity.

When you send or receive information on the internet, there’s a source and a destination address for the data. Your connection is at one of the two ends, depending on whether you’re sending or receiving, and the system you’re communicating with is at the other end.

Some security breaches can occur by intercepting and re-routing information to different addresses. The CCS firewall monitors all activity to ensure your information is not being sent somewhere it shouldn’t.


Another way hackers can gain access to your PC and your data is through the applications and processes running on your computer. If they manage to install malware on your PC, it can send your data back to them or take other damaging actions on your computer.

The containment module in CCS authenticates all applications and processes running on your PC to ensure they’re legitimate. If it identifies anything that could be a threat, it stops them from taking any damaging actions.

If you’re running well-known apps like Microsoft Office, for example, CCS will recognise them and allow them to run normally. Any unrecognised apps and processes run in a special “container” that limits access to the rest of your system.

Those unrecognised apps are monitored while they run and they use a virtual file system and registry. This lets them run like normal, which is important if you run apps that are legitimate but not in the CCS database. This is often the case if you run custom apps in your business.

If the unrecognised app does something dangerous, however, it won’t damage your PC or data because it’s all kept within the special container. It’s a bit like having a virtual PC running alongside your main PC.

Host Intrusion Protection (HIPS)

Comodo’s Host Intrusion Protection works alongside the Firewall and Containment modules to help protect your PC from unauthorised activity. It uses rules-based protection to watch your apps and processes for unexpected behaviour.

If it sees something that breaks one of the rules, it will clamp down on the app immediately so it’s not able to do any damage or expose any of your data.

Rescue Disk

Comodo’s Rescue Disk module will create a custom boot disk that lets you run antivirus scans and other CCS modules directly from the disk. This lets you do pre-boot scans that run before your PC boots into Windows.

If you have any problems that cause Windows not to start properly, the Rescue Disk can help get things sorted out so you’re back up and running.

Website Filtering

Comodo’s Website Filtering module helps protect you against phishing scams and other web-based threats. Phishing attacks are usually sent by email. Scammers send an email that looks like it came from your bank, a credit card service, or some other website that needs you to log in. The email links to a fake page that is set up to look like the real thing. If you enter your login information, it gets sent to the scammer and they can use it on the real site.

CCS website filtering stops these types of attacks by warning you when you’re on a phishing site or blocking the site entirely. It also lets you block sites for certain users so you can create rules based on your needs.

Comodo includes a pre-built list of blocked websites and you can add your own as well.
