Overall Satisfaction with KnowBe4 PhishER/PhishER Plus
KnowBe4's PhishER is a product used to manage spam emails that bypass the email security gateway and reach end-users' email systems. PhishER helps us to manage this issue in a structured way. PhishER does it by using some tools and technologies. First, it uses an email plug-in called Phish Alert Button that installs on end-users' email clients such as Outlook. Once installed, it simplifies the email reporting process by enabling end users to report spam emails directly via the Phish Alert button. So, it makes the email reporting process easy and handy for end users. Once the email is reported, it is automatically collected on the PhishER portal, and the security team can review it. So, by this process, it saves the time and effort of security team. So, PhishER solves two of our problems: email reporting and collecting reported emails in one place.
Pros
- KnowBe4's Phish Alert Button effectively collects all reported emails from end-users in one place.
- The PhishML feature of PhishER effectively auto-scan reported emails using machine learning technologies, providing a tag for each email based on its body content and other aspects.
- The PhishRIP feature works well by allowing the security team to create a query and quarantine all relevant emails from the end user's email system.
Cons
- The PhishRIP query can be improved to find other emails apart from the reported one only.
- They should provide an option to delete the quarantined emails that are quarantined by the PhishRIP feature.
- The PhishML can be improved to produce more accurate results.
- More options to integrate PhishER with 3rd party tools.
- PhishER enables us to report phishing emails quickly and easily through the Phish Alert Button email plug-in.
- PhishER helps us quarantine suspicious emails quickly by using PhishRIP.
- PhishER helps us to investigate the phishing-reported incidents quickly by using PhishML.
PhishER has significantly helped us save time and effort by utilizing its comprehensive set of tools. The Phish Alert Button is installed on Outlook, saving users time and effort when reporting suspicious emails. After the report, all the emails will be collected in a centralized location of the PhishER dashboard. So, in this way, this saves a lot of time for the security team. The PhishML feature auto-scan all the reported emails, and this helps the security team a lot because after the scan, it tags the emails with clean, spam, or Threat.
We have implemented PhishML, PhishRIP, and PhishFlip features. They help us a lot in our daily incidents related to suspicious emails. These capabilities of KnowBe4's PhishER make this software well-balanced for any organization. For my organization, this tool has made a lot of difference. With these tools and capabilities, we are saving a lot of time and effort.
