As an enterprise’s online infrastructures become more complex — from their decentralization to the adoption of cloud, mobile, and internet-of-things (IoT) technologies — patch management has become an even more time-consuming and resource-intensive task.
However, delaying or deferring the application of patches can be risky. In 2019, 60% of breaches were due to unapplied security patches. Data breaches could result in millions of dollars in financial losses, not to mention the hefty fines paid to authorities.
Besides data breaches, there’s also the looming threat of ransomware and targeted campaigns abusing unpatched vulnerabilities. And as the Covid-19 pandemic forced organizations to shift to remote work, the need to patch vulnerabilities in technologies used in this setup (such as VPN) is also heightened. In 2020, the VPN flaw CVE-2019-11510 already had nearly 800,000 detections despite being a relatively new vulnerability.

Once a vulnerability is disclosed, reported, or discovered, it is a race against time for enterprises. For cybercriminals and threat actors, it’s an opportunity. An average organization, for instance, reportedly takes around 69 days to patch a critical vulnerability in its application. Businesses in the U.K. took an average of 60 days to determine that they’ve been breached.
This window of exposure leaves unpatched systems susceptible to threats. In January 2020, threat actors launched attacks against unpatched servers to install ransomware, putting networks of over 80,000 companies at risk.
Virtual patching — or vulnerability shielding — acts as a safety measure against threats that exploit known and unknown vulnerabilities. Virtual patching works by implementing layers of security policies and rules that prevent and intercept an exploit from taking network paths to and from a vulnerability.
A good virtual patching solution should be multilayered. This includes capabilities that inspect and block malicious activity from business-critical traffic; detect and prevent intrusions; thwart attacks on web-facing applications; and adaptably deploy on physical, virtual, or cloud environments.
