"Enhances Email Security with Useful Alerts"
5/5
What do you like best about KnowBe4 Email & Collaboration Security?

I really appreciate KnowBe4 Cloud Email Security for its effectiveness in catching emails and especially the informative banners. The different color labels on incoming emails, with flags like red to indicate phishing signs, provide real information to users about potentially dangerous emails. I love the nudges too; they pop up to alert users when sensitive data that shouldn't be in an email might be sent out, or if someone not usually in the email chain gets added, which is really helpful for similar names. The initial setup was very simple, and after a few sessions for the proof of concept, it was ready for deployment once purchased. Overall, it complements our existing email security very well by preventing threats and helping with data loss prevention using the Prevent module. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

The reporting is getting better but I would like a way to get professional looking reports such as the ones in their security awareness training platform. I have also noticed a few brief hiccups and KnowBe4 integrates Egress and their other security tools. Review collected by and hosted on G2.com.

"Effortlessly Improves Email Security with Intuitive Features"
4.5/5
What do you like best about KnowBe4 Email & Collaboration Security?

I appreciate using KnowBe4 Cloud Email Security (Formerly Egress) because it effectively protects employees from both inbound and outbound email threats and aids in human risk mitigation. I value its capability to reduce risks associated with phishing, accidental disclosure, and providing insights about the riskiest users. The banners are a standout feature, automatically adding visual cues based on risk levels, which help users notice them easily and stay informed about potential threats. Additionally, it efficiently filters out unwanted spam and 'Graymail,' which reduces the noise in our inboxes significantly. The software integrates seamlessly with Microsoft 365, and the initial setup was very easy, with the implementation team making the onboarding process one of the smoothest I have ever experienced. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

The reporting could be better. I get a great dashboard but would love the ability to make custom reports much like my KnowBe4 phishing awareness portal. I would also like for PhishER and the Abuse mailbox to be merged. Review collected by and hosted on G2.com.

Response from Isa Munoz of KnowBe4 Email &...

Thank you for your wonderful feedback on our threat protection capabilities and seamless Microsoft 365 integration, Ricky! We're thrilled to hear that our implementation team delivered such a smooth onboarding experience. We appreciate your suggestions about enhanced custom reporting and PhishER integration with the Abuse mailbox. Your input helps us understand how to better unify the admin experience across our security ecosystem.

"Outstanding Email Security with Smart Tagging and URL Protection"
4.5/5
What do you like best about KnowBe4 Email & Collaboration Security?

How it manages email security at the user-level, the email tags that clearly tell the recipient what the risk of the email is and gives an opportunity to educate the recipient by clicking on the tag, and the "bublewrapping of URLs" that actively checks all links at the time of receipt and time of click to ensure it is going to a trusted location. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

Honestly, so far we have been very happy with the product, and I look forward to it getting more integrated with PhishER+ and other KB4 Security tools. Review collected by and hosted on G2.com.

Response from Isa Munoz of KnowBe4 Email &...

Thank you for this excellent review and for highlighting the educational value of our smart tagging and real-time URL protection! We're happy to hear how effectively our AI/ML is catching sophisticated threats and providing that crucial extra layer of user awareness. We share your excitement about deeper integration across the KnowBe4 ecosystem, and we're actively working to create an even more unified security experience for our customers.

"Great Email Security, but Dashboard UI Needs Improvement"
5/5
What do you like best about KnowBe4 Email & Collaboration Security?

Egress is able to add the links into all of our emails to warn our staff about external email, suspicious mail, phishing emails, etc. It alleviates concerns from my end regarding end user mail. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

The rebranding itself was a little confusing to navigate and the UI of the dashboard leaves a bit to be desired for myself since I don't live within it very often. Review collected by and hosted on G2.com.

"Great visibility and Efficient Bulk Remediation,"
5/5

Great visibility into the email traffic. I also like the ability to easily see similar malicious emails and remediate them in bulk. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

at times it would be nice if dangerous emails could be remediated from the list instead of opening them. Review collected by and hosted on G2.com.

"Smart Banners and Graymail Are Game Changers, but Phish Blocking Needs Improvement"
5/5
What do you like best about KnowBe4 Email & Collaboration Security?

The smart banners and graymail have been a true game changer for our company. We have cleaned up inboxes of clutter and allowed our people to focus on important email. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

I would like it to be a little more forceful in its blocking of phish emails when they are reported. We do also still have the occasional emails make it through all the filters that is obviously malicious. Review collected by and hosted on G2.com.

It's easy to allow it to simply do its job and become less alert to threats because they are blocked. Review collected by and hosted on G2.com.

"Egress has been a great replacement for Mimecast!"
5/5
What do you like best about KnowBe4 Email & Collaboration Security?

Egress engineers made this deployment go very smoothly, there are almost too many positives to list but the most important pieces of Phishing and Ransomware detection have caught attacks that our former vendor and Microsoft Online protection have not caught in the past. The DLP feature has been great and has stopped multiple misdirected emails one of which could have been very harmful. The users love the Graymail folder and it really helps keep inboxes free of newsletters and solicited emails which has definitely enhanced productivity. Review collected by and hosted on G2.com.

What do you dislike about KnowBe4 Email & Collaboration Security?

The only enhancement request I would have is that when you mark something as "not graymail" it would move the message into the users inbox. Review collected by and hosted on G2.com.

Response from Isa Munoz of KnowBe4 Email &...

Thank you for sharing such a comprehensive review of Cloud Email Security! We're thrilled to hear about your smooth deployment experience and how our advanced detection capabilities are catching threats that other solutions missed. I'll share your suggestion about the Graymail folder functionality with our team. Thank you for being a valued KnowBe4 customer!
