SecMgr was easy to implement, configure & use with our existing AD infrastructure in just few minutes! Support is also very good from their side (it's one of my favorite providers). It has been used by more than 100 clients so far across all verticals including Banking/Fintech etc - no issues at any point till now!! Overall security management using secmngr-PKI solution alongwith other products like O365 Security Center / SCC MFA integration makes day brighter compared when doing it manually or without this toolset! Highly recommend!! Nothing as such but if you are looking into an integrated product then definitely go ahead since there will be nothing better out here once implemented. We have managed certificate issuance process easily right within Sharepoint environment itself which reduces manual effort significantly thereby increasing productivity levels tremendously!
