Explanation
In deceptive phishing, fraudsters impersonate a legitimate company in an attempt to steal people's personal data or login credentials. Those emails frequently use threats and a sense of urgency to scare users into doing what the attackers want.
Spear phishing is carefully designed to get a single recipient to respond. Criminals select an individual target within an organization, using social media and other public information - and craft a fake email tailored for that person.

Cisco Umbrella protects users from accessing malicious domains by proactively analyzing and blocking unsafe destinations - before a connection is ever made. Thus it can protect from phishing attacks by blocking suspicious domains when users click on the given links that an attacker sent.
