The best part of threatconnect was its ability to identify threats, provide remediation advice as well as providing us with alerts for our users when they are at risk from known or unknown cyber attacks/threats that can be mitigated by their security solutions - it also provided an easy way to monitor all devices within my organization's network perimeter (including cloud).
It could not differentiate between phishing emails sent out internally versus those received via email outside your organisation which made tracking down who had been impacted difficult sometimes if you were looking solely through this tool alone. I would highly recommend using Threat Connect because we have seen significant improvements since implementing these tools into our environment. We use them primarily but other vendors such as McAfee offer similar products so check each vendor against what others may already do before making any decisions about purchasing additional software packages / services etc.
