Comodo Group, Inc. is a privately held group of companies providing computer software and SSL digital certificates, based in Clifton, New Jersey[not verified in body] in the United States. It has offices in the United Kingdom, Ukraine, Romania, China, India, Turkey and Clifton, NJ.[not verified in body]


The company was founded in 1998 in the United Kingdom,[1] by Comodo CEO, Melih Abdulhayoğlu, a technologist and an entrepreneur. Comodo relocated to the United States in 2004. Comodo's product line is focused primarily on computer and internet security.[2] The firm operates a Certificate Authority that issues SSL certificates, offers a computer security suite that includes antivirus and firewall protection and offers other web and network protection services.

Comodo Companies[edit]


In response to Symantec's comment over the effectiveness of free Antivirus software, on September 18, 2010, the CEO of Comodo Group Melih Abdulhayoğlu challenged Symantec to see which products can defend the consumer better against malware.[10] Symantec responded saying that if Comodo is interested they should have their product included in tests by independent reviewers.[11] On 29 September 2010, Neil J. Rubenking, the lead analyst for security of PC Magazine, published an article on Comodo Antivirus 5.0 that[12][13] concluded that Comodo Antivirus 5.0 blocked a higher percentage of malware than Norton AntiVirus, but was less effective than the Norton solution when it came to malware removal. Rubenking's review also noted that the Comodo malware blocking gave a number of false positives which he felt tarnished Comodo's results.

On March 15, 2011, Comodo reported that a user account with an affiliate registration authority had been compromised which was used to create a new user account that issued nine certificate signing requests.[14] Nine certificates for seven domains were issued.[14] The attack was traced to IP address, which originates in Tehran, Iran.[14] Though Comodo initially reported the breach was the result of a "state-driven attack", it subsequently stated that the origin of the attack may be the "result of an attacker attempting to lay a false trail."[14][15]

Such issues have been widely reported, and has led to criticism of how certificates are issued and revoked.[16][17][18][19]

All of the certificates have been revoked.[14] Microsoft has issued a security advisory and update to address the issue.[20][21]

On March 26, 2011, a person under the username "ComodoHacker" made several posts to claiming to be an Iranian responsible for the attacks.[22][23]



Comodo was founded as a Certificate Authority selling SSL and digital certificates. Its primary source of revenue comes from related products to business and enterprises.

Since 2004, when it introduced Comodo Internet Security, Comodo has attempted to expand into the consumer software market. Comodo offers many products as freemium: They are available for download free of charge,[24] but additional features or more feature-rich editions are available for a fee.[25] Among Comodo's free products is the Comodo Internet Security, incorporating a personal firewall, Host-based intrusion detection system and antivirus program.[26]

Comodo Endpoint Security Manager (CESM is a server product for managing the security settings on network endpoint computers. The firewall and antivirus components managed by CESM are versions of the same software components in the consumer desktop versions of Comodo Internet Security.[27]

Other Comodo branded freeware security tools include an anti-malware tool, and a memory firewall that protects against over 90% of buffer overflow attacks.[28] For an additional fee, Comodo product users can subscribe to Comodo's computer cleaning and optimizing services for real-time computer assistance. Comodo also offers Comodo System Cleaner, which includes a free registry cleaner program,[29] Comodo Unite (formerly EasyVPN), a virtual private networking (VPN) program, and Comodo SecureEmail, an email encryption program that allows S/MIME email users to send emails to any email user without exchanging keys beforehand. These products come in both a limited free version and a more functional professional release.

On February 7, 2013, Comodo Internet Security Complete earned the PCMag Editor’s Choice award. They gave the suite 4.5 of 5 stars and a rating of Excellent. Writing for the magazine, Neil J. Reubenking concluded “The biggest win for Comodo Internet Security Complete 2013 isn't in features, but in support."[30] In August 2012, Top Ten Reviews gave Comodo Internet Security 2012's firewall a 9.88 out of 10, higher than any other product evaluated.[31] Neil Rubenking of PC Magazine gave Comodo Internet Security 2012 a rating of 4 of 5, Excellent. He wrote "Very inexpensive. Very good malware blocking. GeekBuddy remote help extremely effective at cleaning up malware, especially rootkits."[32] c|net Magazine gave Comodo Internet Security a score of 5 out of 5.[33]

January 29, 2013, Neil Rubenking of PCMag rated the Comodo Firewall as "Excellent". He noted that with recent versions of Windows including a firewall it is important that alternative products be free and provide additional features, which are true for the Comodo Firewall.[34] May 7, 2012 CNET Magazine rated Comodo Firewall "Spectacular" and gave it 5 of 5 stars. They referred to it as more capable than the firewall that comes free with recent versions of Windows.[citation needed]

In August 2012, Jeffery L. Wilson of gave Comodo System Utilities an Excellent rating, 4 of 5 stars. He states as his "Bottom Line" conclusion "Comodo System Utilities is a free and effective system-enhancing utility that is as potent, if not more so in certain cases, as paid apps".[35]

On June 17, 2010 a cNET Editor's review gave the Comodo Dragon a 5 of 5 star score and a rating of Spectacular. they concluded "Dragon is not only fast, but like Google Chrome, it is not strewn with numerous icons, leaving more room for Web viewing. For those who are extra cautious about their online security, or for those who are worried about Google's data-mining, this fast browser is a great choice.[36]

Comodo EndPoint Management System (CESM)[edit]

The Comodo Endpoint Management System is a centralized device management system that includes the ability to distribute pc security software. The software used includes the same firewall and antivirus systems that makeup Comodo Internet Security. [37][38]
