Without more context and given the categories you've posted, I see 2 possibiliities:

Denans (is someone's (sur)name), Thai envoy/ambassador/emissary

or

Thaise Denans (first name surname), envoy/ambassador/emissary
although as first name it's usually spelled Thais but who knows?

more context (where this is used, what it has to do with computers/IT etc) would be helpful
