"Automates Security Actions with a Great UX"
5/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

The feature I find most valuable is PhishER's automated email triage and threat analysis capabilities. It allows our Cybersecurity team to efficiently process employee-reported emails, reduce false positives, identify malicious campaigns, and respond more quickly to potential phishing threats. This improves operational efficiency while strengthening our overall phishing defense program. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

PhishER provides strong operational value, but the platform's effectiveness depends on proper configuration and maintenance. As phishing tactics evolve, rules and automation workflows must be regularly reviewed and adjusted. I would also like to see continued improvements in reporting, workflow customization, and integration capabilities to further streamline investigation and response activities.

"Security awareness done right, without adding administrative overhead"
4.5/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

What I like most is how quickly we can sort through user-reported emails and focus on the ones that actually matter. It saves the team a lot of time and helps us respond faster to real threats. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

The interface is generally easy to use, but some of the automation and workflow settings can take a bit of time to learn. Once configured it's great, but there's a slight learning curve if you're new to the platform. Review collected by and hosted on G2.com.

"PhishER Simplifies Phishing Review and Stops Threats Organization-Wide"
5/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

PhishER makes reviewing potential phishing emails so much easier. It integrates with most common email platforms, and gives the end user a button to click to report a suspicious email. It splits out the headers so they are easy to find and review, automatically scans attachments, and in most cases will automatically categorize submitted emails for you. Once it makes the determination that the email is malicious, it will automatically pull matching emails from other inboxes in your organization. It has saved us multiple times. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

The only real pain point we have had with the product, is getting users to click the Phish Alert Button, rather than forwarding the email to our helpdesk account. That isn't a fault of the platform, but a user training issue. It does have a limitation where if the user has replied to the email or forwarded it before clicking the button, it doesn't give you the information you need from the original email, but submits the most recent email in the thread. I'm not sure if that is able to be fixed. But, once again, it boils down to a user training issue. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

Just starting out can definitely be jarring. There are so many extra features and things named weirdly that just a quick glance can be overwhelming. Luckily we had someone to help walk us through the basics and build up from there. Review collected by and hosted on G2.com.

"Great for Phishing Reviews but Pricey"
3/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

I find KnowBe4 PhishER/PhishER Plus easy to use, which is probably one of its best features for me. It simplifies the process of reviewing reported phishing emails by collecting them in one place and facilitates blocking emails, URLs, and file hashes, enhancing our company's security. The integration with VirusTotal is particularly beneficial—it scans links and files in reported emails and informs me about any reports from its vendors, which aids in making informed blocking decisions. The initial setup was pretty simple, thanks to clear instructions and helpful support. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

The price is a bit high and they require a 3-year contract, which prevents me from trying their competitors. The platform can be slow to respond at times, but that may be due to network traffic - it's hard to tell. I have often had the blocked emails fail due to hitting a max limit, which appears to be Microsoft related. Review collected by and hosted on G2.com.

"Effortless Phishing Defense with Quick Setup"
5/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

I really like how KnowBe4 PhishER/PhishER Plus allows our users to report phishing emails easily and helps automate the review process for these reports. The setup was super easy, and we quickly got it up and running with the support of their team. Its ease of use and customization have been great, especially since most reported emails are automatically evaluated and the right actions are taken, which saves us a lot of time. It also boosts our confidence in determining whether a reported email is truly malicious or not. We also love the integration with Crowdstrike; it makes scanning attachments for malicious content super easy, eliminating the need for manual downloads. The platform is straightforward compared to Microsoft’s Defender, with less complexity in seeing what happens behind the scenes and understanding decision-making processes.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

Sometimes the report button in Outlook is a bit slow to load, but other than that, we haven't really run into any issues. Review collected by and hosted on G2.com.

"Boosts Security Awareness with Customization Options"
3.5/5
What do you like best about KnowBe4 PhishER/PhishER Plus?

I use KnowBe4 PhishER to run simulated phishing campaigns for my organization. It has allowed me to bring security awareness to my organization and keep the organization on top in terms of being aware of new phishing tactics and trends. I like that it gives me the ability to select from a library of templates but also create my own if I needed to. The library template is helpful when you're unsure of the direction of where to go. It allows me to be able to select a template that is trending. Creating my own template adds value because it allows me to do my own research and generate something that is more targeted to my organization. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?

The UI could definitely be improved and sometimes the functionality with previewing the phishing template you edited could be buggy. Review collected by and hosted on G2.com.

New content is added regularly allowing us to provide monthly training with new content. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 PhishER/PhishER Plus?
