Symantec Endpoint Protection (SEP) 14.3 RU10 (Release Update 10) is here. While it isn’t a major version jump, this update focuses heavily on performance optimization, deep OS integration, and endpoint hardening. Title: What’s New in SEP 14

If you are still on RU7, RU8, or an early RU9 build, RU10 is a compelling "must-upgrade" for stability alone. Here is what you need to know before you hit "deploy." Reduced latency on high-throughput NICs (10 GbE and above)

4.1 Reduced Disk I/O and CPU Spikes

Through a redesigned scan cache (content-aware caching), repeated scans of the same files (e.g., during nightly scheduled scans) now consume 70% less disk throughput. The background idle scan’s CPU usage caps at 5% on modern multi-core systems.

5. Updated Network Threat Protection (NTP) Engine

The NTP engine, responsible for firewall and intrusion prevention, gets a signature and efficiency update:

• Reduced latency on high-throughput NICs (10 GbE and above).
• Better handling of IPv6 fragment reassembly.
• New IPS signatures for recent CVEs (e.g., Log4j variants, HTTP/2 rapid reset attacks).

Q3: What is the disk space requirement for upgrading SEPM?

A: The SEPM upgrade process requires at least 10GB free space for temporary backup of logs and database migration. Post-upgrade, the footprint remains similar (±1GB).
