Hi,ASA firewall has different models and interfaces depending on the network size and performance requirements.You need to check the respective model's data sheet to get those info.Cheers! 

hi @lukaklepic ,My understanding is, ESA uses ASCII encoding for dictionary matching, which does not support diacritics such as ř, í, č, and ý. Therefore, the dictionary entry with these characters is not recognized by ESA as a valid match.
