This continuous flow of information ensures that cloud-based security remains effective against the latest threats.
3. Limitations of Traditional Antivirus:
a. Signature-Based Detection: Traditional antivirus software relies heavily on signature-based detection, which matches known malware signatures to identify threats. This approach is effective against previously identified malware but falls short in detecting new and unknown threats. Cybercriminals continually develop new variants of malware, often modifying their code to evade signature-based detection. As a result, traditional antivirus struggles to keep up with the rapidly evolving threat landscape.
b. Limited Scope and Coverage: Traditional antivirus solutions are often limited in scope, focusing primarily on protecting endpoints such as computers and mobile devices. However, modern cyber threats target a broader range of assets, including cloud environments, network infrastructure, and IoT devices. Traditional antivirus may not provide comprehensive protection across all these assets, leaving organizations exposed to potential vulnerabilities.
c. Slow Response to Emerging Threats: Traditional antivirus programs typically rely on periodic updates to incorporate new threat signatures. This lag between updates creates a window of vulnerability during which new threats can bypass defenses. In contrast, cloud-based security solutions continuously update their threat intelligence, enabling faster detection and response to emerging threats. The slow response of traditional antivirus can leave organizations at risk of significant damage before updates are applied.
d. Resource Intensive: Traditional antivirus programs can be resource-intensive, consuming significant CPU and memory resources on local devices. This resource consumption can slow down device performance, impacting productivity and user experience. Cloud-based security offloads much of the processing to the cloud, reducing the burden on individual devices and ensuring optimal performance.
