Zscaler is here to help you mitigate the impact of Log4Shell and prevent other zero-day vulnerabilities

Join our experts on March 1 for insights on how to manage the long-term impact of the Log4j vulnerability.

About the Log4j vulnerability

Apache Log4j is an open source logging library used in millions of enterprise applications and cloud services. The Log4Shell exploit allows attackers to take over devices and carry out a range of attacks against vulnerable targets.

By now, many organizations have updated Log4j libraries and protected their most critical applications and assets. However, Log4j’s widespread use can make it difficult to conclusively hunt down across the enterprise. Also, sophisticated attackers could have planted backdoors in vulnerable systems before patching, allowing them to break in and carry out future attacks.

That’s why you need a long-term mitigation strategy for Log4Shell.
