Have seen Suricata, McAfee, PAN, and TippingPoint alert and even-potentially block on things like Nmap scans, but not if Sniffjoke or similar advanced evasion technique is utilized.

There are plenty of threads, even in this forum, about modifying Nmap to get through modern IDS/IPS without being noticed. Or just use like pbscan or write your own in Python or whatever else. Metasploit-framework even does things differently. It’s mostly about Window size, pps, retries, etc.
