Sentiment score
5.0
Proofpoint Email Protection reduces phishing, streamlines operations, improves email hygiene, lowers security incidents, and enhances financial management.
The return of investment was quick and easily seen within the first 90 days, and that is when an actual quarterly meeting, a QBR, would take place to be able to show that return on investment.
The ideal situation would be to have all these portals combined into one unified dashboard.

After Proofpoint Email Protection, phishing has been completely eliminated, so it is working very efficiently.

Room For Improvement

Users seek improvements in data management, real-time updates, UI, training, dark web sources, and reduced false positives on Cybersixgill.
Proofpoint Email Protection requires better AI, usability, and support, addressing high costs and inefficiencies to improve security and productivity.
During the onboarding, that is the most crucial part to make sure that the organizations who purchase Cybersixgill ensure that they actually have the right person or persons to go through the onboarding.
I hope that in the future, Cybersixgill can separate the leaked credentials by email and domain.
Soc Analyst
The older legacy user interface just took a little to work with, and the new unified interface, as it was able to do more and more of the functionality of the old one, the product just got easier and easier to use.

In addition to the UI improvements, I would appreciate an increase in the speed of the tasks being processed on the pod.

Setup Cost

Cybersixgill offers competitive pricing, balancing affordability with market standards, though cost adjustments and currency exchange can affect value perception.
Proofpoint Email Protection costs $2-$7/user/month, seen as high, but justified by its robust security features.
Based on the needs of the customer, there was always a negotiation that could be done to get a slightly lower price.
Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees.
Products and solutions director at ITVikings
Given my other experience with other vendors, I think they are a bit on the high end and a bit on the pricey end for the email security functionality that we were using.
Sr Security Engineer at a comms service provider with 201-500 employees
Although it is a bit costly compared to Mimecast, Defender, and Cofense Vision, it is efficient and strong in security, so I do not mind the cost because I will not reduce my security risk.

Valuable Features

Cybersixgill offers user-friendly threat intelligence features, tracking, and analysis from deep and dark web, enhancing security monitoring.
Proofpoint Email Protection enhances security with advanced threat detection, customizable policies, and integration, reducing phishing and administrative workload.
The best feature that Cybersixgill offers with respect to dark web intelligence is that they provide very good screenshots of where the particular data has been taken, which allows for better visualization and understanding of the scenario, with the source being indicated through onion links that can be reverse-engineered for further investigation.
Associate at a financial services firm with 10,001+ employees
What specifically stands out to me about the cyber threat intelligence feature is the speed and the depth from the data lake.
I appreciate that I can search in the dashboard for credentials by entering the domain directly rather than navigating through other sections, making it very easy to check the dashboard.
Soc Analyst
Without Proofpoint Email Protection, most of these emails would have come through, slipped through Exchange, gotten into the user's mailbox, and created a lot of trouble for the organization.
Cyber Security Engineer at IT Naturally
Proofpoint Email Protection has positively impacted my organization by ensuring we are not at risk of a breach through email.

Featured Reviews

Proactive dark web intelligence has reduced breach impact and protects organizations quietly
Cybersixgill has one of the largest data lakes around. I think the way they can be improved is to be able to initially during the onboarding, make sure that the false positives are correctly addressed to really do the tweaks that need to be done to filter through exactly what the organization is trying to accomplish and give them the outcomes they are looking for without all the extra noise or chatter. I just think during the onboarding, that is the most crucial part to make sure that the organizations who purchase Cybersixgill ensure that they actually have the right person or persons to go through the onboarding to make sure that the data lake feeds can be properly set up and organized so it can filter through the noise and the chatter.

Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.
