Comodo, founded in 1998 and based in Bloomfield, New Jersey, have built their reputation on a prevention-first approach to cybersecurity. Although the company rebranded as Xcitium in 2022, the Comodo name remains active for their consumer-focused offerings, especially antivirus software and internet security tools. What sets Comodo apart is their "default-deny" model, a proactive method that automatically contains unknown files before they can harm your system. This technology, combined with real-time malware protection, sandboxing, and customizable firewall settings, forms the core of their free and paid solutions. Comodo’s Internet Security suite, available for Windows, adds extra layers such as secure shopping, VPN access, and live expert support. While some users highlight the software’s powerful features and lightweight performance, others note usability and customer support challenges. Despite this, Comodo has earned recognition in third-party lab tests and continues to appeal to users looking for solid baseline protection, especially those on a budget. Whether you’re considering their no-cost antivirus or a full-featured security suite, this review explores the tools, strengths, and limitations of Comodo’s approach to personal cybersecurity.
