Security readout for executives and security teams

This is an old reported availability issue in ZoneAlarm Pro 3.0 and 3.1. When set to block all traffic, a large volume of SYN traffic was reported to consume CPU and memory. The vendor reportedly could not reproduce the issue, so treat the evidence as limited. Exposure is likely limited to environments still running legacy ZoneAlarm Pro 3.0 or 3.1, especially on internet-reachable hosts where the product is configured to block all traffic. Low operational priority unless legacy ZoneAlarm Pro 3.0/3.1 is still deployed. If present on exposed systems, prioritize retirement or replacement because the product is obsolete and evidence is incomplete. Mitigation focus: Identify and retire any remaining ZoneAlarm Pro 3.0 or 3.1 installations.; Check vendor or successor product guidance for supported upgrade paths.; Avoid relying on unsupported legacy personal firewall software for critical availability..
