Comodo

Comodo is a cybersecurity company offering internet security software, SSL/TLS certificates, endpoint protection, and threat intelligence solutions for both consumers and businesses. The company is well-known in the security industry for their Certificate Authority operations and for offering genuinely free antivirus and firewall software for consumers alongside paid premium security suites.

Comodo's consumer security products include their free antivirus (one of the better free options available) and premium Internet Security suites. Their SSL certificate business serves website owners needing to secure their sites, with pricing that is competitive against industry leaders like DigiCert and GlobalSign.

Comodo's free tier antivirus is a genuine, full-featured product—not a crippled trial—making it worth evaluating before purchasing any paid security suite. For paid plans, annual billing and multi-year commitments provide meaningful savings over monthly pricing.
