The company was founded in 1998 in the United Kingdom,[1] by Melih Abdulhayoğlu, who remains its CEO. The company relocated to the United States in 2004. Its product line is focused on computer and internet security.[3] 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]

  • Comodo CA Lmtd: Based in Manchester UK, is a digital certificate authority that issues SSL and other digital certificates. According to, Comodo is the second most used provider of SSL digital certificates.[4][5]
  • Comodo Security Solutions, Inc: Based in Clifton, NJ, develops and markets security software for commercial and consumer use. This includes web site vulnerability and penetration scannng, corporate and consumer pc security systems and other networks security products. Comodo AntiVirus Labs support all versions of their security systems.[6]
  • Based in Louisville Ky, provides managed DNS services.[7][8]


In response to Symantec's comment over the effectiveness of free Antivirus software, on September 18, 2010, the CEO of Comodo Group challenged Symantec to see which products can defend the consumer better against malware.[9] Symantec responded saying that if Comodo is interested they should have their product included in tests by independent reviewers.[10] On 29 September 2010, Neil J. Rubenking, the lead analyst for security of PC Magazine, published an article on Comodo Antivirus 5.0 that[11][12] 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.[13] Nine certificates for seven domains were issued.[13] The attack was traced to IP address, which originates in Tehran, Iran.[13] Though the firm initially reported that 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."[13][14]

Such issues have been widely reported, and has led to criticism of how certificates are issued and revoked.[15][16][17][18]

All of the certificates have been revoked.[13] Microsoft has issued a security advisory and update to address the issue.[19][20]

On March 26, 2011, a person under the username "ComodoHacker" made several posts to claiming to be an Iranian responsible for the attacks.[21][22]
