The correct answer is D. F2F . Protections with high inspection impact generally require deeper processing that cannot remain fully accelerated in SecureXL. In Check Point performance terminology, F2F means traffic is forwarded from SecureXL to the Firewall path for inspection. Performance tuning documentation describes F2F packets as packets that SecureXL forwarded to the Firewall in the slow path, while accelerated traffic remains in the fast path. Threat Prevention protections, especially high-impact IPS protections, can require deeper packet, stream, or protocol analysis and therefore increase the portion of traffic processed outside full SecureXL acceleration.
Check Point IPS documentation explains that Performance Impact is the measure of how much a protection affects gateway performance and warns that activated protections with higher performance impact can cause connectivity or performance issues. The IPS optimization guidance further explains that some protections require more system resources to inspect traffic and recommends focusing on lower-impact protections when reducing gateway resource use is necessary. SXL is the fully accelerated path, PXL is medium-path inspection with acceleration assistance, and CPASXL relates to active streaming acceleration. High Protection Impact aligns with F2F because the gateway must perform deeper inspection. Reference topics: IPS Performance Impact, SecureXL packet paths, F2F, PXL/SXL, IPS optimization.
